INTRODUCTION

In accordance with the data published by the European Commission, the network

interconnection fees in the fixed line telecommunications network of Lithuania are among the

highest in the EU. In view of this situation, the Lithuanian Communications Regulatory

Authority (hereinafter, RRT) adopted a decision regarding application of the the hybrid

LRAIC (hereinafter, HY-LRAIC) model.

The purpose of HY-LRAIC model is to establish the interconnection service costs that would

be incurred by an effective operator in a competitive market. The model formation process

(until May 2007) is presented in the chart below.

Chart 1. HY-LRAIC model formation process.

HY-LRAIC model is formed by combining separate elements of BU-LRAIC and TD-LRAIC

models. I.e. first, the differences of BU-LRAIC and TD-LRAIC model results are established,

then the reasons for these differences are indicated. Following the above analysis and

pursuant to the comments given by TEO LT, AB (hereinafter, TEO), RRT adopts a decision

regarding the costs level of an efficient operator in a competitive market.

The purpose of the HY-LRAIC model documentation is to describe the MS Excel HY-

LRAIC model, its operating principles, structure, and the technological – technical –

management – economic solutions used and to present its operation manual.

1 MODEL STRUCTURE

1.1 List of cost objects

The list of cost objects in HY-LRAIC model should be consistent with service definitions

published by RRT rules; therefore it will comprise the following cost objects provided in a

table below.

Table 1. List of cost objects modeled in the HY-LRAIC model

No. Cost object Definition

1. Call set-up Establishment of communication link and termination in the operator network. Call set-up is ascribable to the type of costs accounted for per call, i.e. once for each call.

2. Termination

Call transfer from the local telephone switch (inclusive) which is located closest to the subscriber who is called and which has or can provide network interconnection, to the network terminal point where this call is terminated.

3. Origination

Call transfer from the public telecommunications network (hereinafter, the network) terminal point (defined in Par. 59 Art. 3 of the Law on Electronic Communications) where the call in initiated, to the telephone switch (inclusive), which is located closest to the call initiating subscriber and in which network interconnection is or can be provided.

4. Type I transit Call transfer via one network transit switch (including this switch).

5. Type II transit

Call transfer from (to) network local switch (excluding this switch), which is located closest to the calling subscriber (the subscriber called) and in which network interconnection is or can be performed, to (from) the network transit switch (including this switch), where network interconnection is or can be performed.

6. Type III transit

Call transfer from the network transit switch (excluding this switch), in which network interconnection is or can be performed, to the network transit switch (including this switch), in which network interconnection is or can be performed.

7. Type IV transit

International call transfer via one network international switch (including this switch), when the international call originates in the network, which is on the territory of the Republic of Lithuania.

6

No. Cost object Definition

8. Type V transit

Transfer of international calls between the network transit switch (excluding this switch) and network international switch (including this switch), where the international call originated in the network, which is on the territory of the Republic of Lithuania.

9. Local point of interconnection

Geographically defined location where public communication networks of the came or another entity are connected physically or logically to enable electronic communication service recipients of one entity to use interconnection and/or the services provided by the connections with the other entity‘s service recipients including all the entities with the access to respective networks. Network interconnection is a special type of access.

10. National point of interconnection

Geographically defined location where public communication networks of the came or another entity are connected physically or logically to enable electronic communication service recipients of one entity to use interconnection and/or the services provided by the connections with the other entity‘s service recipients including all the entities with the access to respective networks. Network interconnection is a special type of access.

11. Capacity at the point of interconnection

Telephone switch access capacity allocated at the point of interconnection measured by 2 Mbit/s ports and enabling call exchange between countries.

The list of cost objects is consistent with the list of cost objects in BU-LRAIC model. As

refers to the TD-LRAIC model the only difference in the service definition is the treatment of

costs related to call set-up and local point of interconnection . In the TD-LRAIC model no

separate cost object for call set-up has been established and all the related costs have been

allocated to the costs of corresponding cost objects related to per minute costs.

From this perspective the costs of services calculated in TD-LRAIC model are reduced by the

costs of call set-up related costs and instead of it a new service call set-up is defined.

1.2 Network elements and activities

The list of network elements in HY-LRAIC should be consistent with model reference papers

published by RRT. Since both in BU-LRAIC and in TD-LRAIC the list of network elements

7

are consistent with RRT guidelines, in HY LRAIC the list of network elements coming from

TD-LRAIC model was applied.

This makes the HY-LRAIC more comparable with actual operator’s situation and the TD-

LRAIC model developed by TEO.

List of network elements applied in HY-LRAIC model is provided in annex No. 1.

1.3 Homogenous cost categories (HCC)

The list of homogenous cost categories (HCC) used in HY-LRAIC model is in compliance

with the mandatory guideline principles announced by RRT. Considering that the list of HCC

used in both BU-LRAIC and TD-LRAIC models is compliant with the guideline

requirements, the HY-LRAIC model uses the HCC list contained in the TD-LRAIC model.

This ensures higher explicitness of HY-LRAIC model, the compliance with the real situation

and comparability with the TD-LRAIC model prepared by TEO.

The list of homogenous cost categories (HCC) used in HY-LRAIC model is presented in

Annex No 2.

2 CAPEX

In HY-LRAIC model, the principles of accounting for total costs of non-current assets

(CAPEX) are harmonized with the mandatory principles published by RRT in the guidelines

documents. In order to ensure the compatibility of the model with the actual historical

accounting data of TEO, the straight-line asset depreciation accounting method is used.

The following formula is applied for calculation of current cost related to fixed assets:

)()()()( nHGnCDWACCnNRCnC ����

Whereas:

� )(nNRC – average net replacement cost for period n;

� WACC – weighted average cost of capital;

� CD(n) – current depreciation in period n;

� HG(n) – holding gain in period n.

CAPEX HCC cost category based on asset revaluation tables used in TD-LRAIC

model;

� Asset useful life periods – average weighted asset useful life periods by CAPEX

HCC categories used in TD-LRAIC model and presented by TEO.

� Price change indices (for calculation of asset storage income (loss)) – asset price

change indices presented by TEO.

2.1 Switching network

The valuation of switching network should be consistent with HY-LRAIC modeling

principles stated in executive orders published by RRT. In specific it should reflect only the

costs an efficient operator would incur.

Here it should be stressed that the costs should reflect the choice of an efficient operator - an

efficient operator should represent the lowest possible costs to build the network serving the

same level of service at the same quality as the current network. Because of this reason in

HY-LRAIC model switching network is valued based on the same principle as in the BU-

LRAIC model.

In specific determination of the value of the switching network is described in the following

sections.

2.1.1 General principles for modeling switching network

Valuation of costs from increase in switching network equipment in BU-LRAIC model is

based on traditional digital technology – Siemens EWSD technology.

Valuation of switching network equipment capacity consists of the following:

� traffic modeling by routing matrixes and M-curve;

� determination of switch and subscriber capacity numbers;

� valuation of switch and subscriber equipment capacity.

10

Equipment containing the switches is divided into three parts:

� equipment, the capacity of which is determined by the busy hours traffic erlang BHE

(e.g. number of ports);

� equipment, the capacity of which is determined by the number of busy hour calls

(e.g. central processing unit);

� equipment, the capacity of which is determined by the number of subscriber lines.

2.1.2 Routing matrix

The purpose of the Routing matrix model:

� calculation of on-switch and off-switch traffic ratio (ratio is used in the Network

design model);

� calculation of traffic minutes for each network element (minutes are used in the

Economic model).

Routing matrix model results are used in the Network design (for dimensioning) and the

Economic model (for interconnection services cost evaluation).

The following matrixes are used in the Routing matrix model:

� minute matrix – provides data of the traffic structure in minutes on the network;

� routing factor matrixes – provide data of the routing factors of network elements;

� weighted minute matrixes (or network element matrixes) – provide data minutes for

network elements.

All the matrixes are uniform as stated below.

11

Routing factors and network element matrixes are designed separately for the following

network elements:

� subscriber unit;

� local switch;

� transit switch;

While summing the minutes in the network element matrix, the result is the number of

minutes for the network element. This figure is used afterwards in the Economic model for

the estimation of cost for one minute on a particular network element.

While summing up the fields that are in matrix diagonal (going lower from left to right), the

result is the total number of on-switch minutes. Their ratio with the total minutes is the ratio

of on-switch minutes to the total traffic.

The Routing matrix model provides the results according to the possible number of local

switches used by an efficient operator. Therefore, the Routing matrix model results are used

in Economic and Network design models and represent the number of local switches

calculated in the Network design model.

2.1.3 M – curve calculations

The M-curve represents the load of traffic in telecommunications network during certain

periods of the day.

The M-curve model calculates coefficients for BHT estimation. According to the data

received from the M-curve model, the amount of the necessary core network equipment is

determined.

Calculations in the M-curve model are based on the operator’s hourly traffic data on

workdays and weekends and other non-working days.

The model provides the following results:

� M-curve coefficients, which estimate BHT in the overall traffic;

� M-curve coefficients, which estimate work-day traffic.

Coefficients are calculated separately for the following services:

� on-net calls;

� interconnection calls;

� internet calls (dial-up).

12

For the calls from other networks and for the calls sent by transit, the same M-curve

coefficients are used as for the calls to the other networks.

The main principles for M-curve calculations:

� M-curve coefficients, which estimate the part of BHT are calculated by multiplying

the certain busy hour call traffic by 24 and dividing it by the workday traffic.

� M-curve coefficients, which estimate the call traffic on the workdays, are calculated

by dividing the call traffic on a workday by the average workday. The following

formula is used for the calculation of the coefficients:

57

255

���

hdwdwd

k

Explanation:

o wd – number of charged minutes on a workday;

o hd – number of the charged minutes on holidays and weekends.

Peak and off-peak price differentiation ratios are also calculated with a help of M-curve

model. These ratios are used for average service unit cost differentiation into peak and off-

peak. Following rules for differentiation are applied:

� Interconnection service unit cost differentiation into peak and off-peak is based on

local on-net calls tariff differentiation.

� Ratio, which is used for average unit cost differentiation to peak, is calculated as a

ratio of peak tariff for a local on-net call to average tariff for a local on-net call.

� Ratio, which is used for average unit cost differentiation to off-peak, is calculated as

a ratio of off-peak tariff for a local on-net call to average tariff for a local on-net call.

� Average tariff for local on-net calls is calculated based on actual tariffs and M-curve

for local calls.

� For calculating the average tariff for local on-net calls peak and off-peak time

intervals are defined according to the same rules as for interconnection traffic.

2.1.4 Subscriber units

The capacity of one subscriber unit is based on the number of subscriber modules. Subscriber

modules are subscriber unit’s structural units facing access network using the line card and

facing switching network using a 2Mbit/s link. One subscriber unit may consist of several

13

modules. The number of modules could differ depending on the producer of the module. The

number of subscriber modules depends on the BHE generated by the subscribers. The number

of subscriber modules is calculated using special engineering models. For the calculation, the

data of the generated busy hour traffic and the number of subscribers is necessary.

2.1.5 Local switches

There are two types of ports in the local switches: 2 Mbit/s ports, for the connection of

transmission lines to subscriber units and 2 Mbit/s ports for the connection of transmission

lines with other local and transit switches. Both types of ports are almost identical according

to their functions, yet their numbers are calculated in a different way.

In the local switches, the number of 2 Mbit/s ports dedicated to connection of transmission

lines with subscriber units is equal to the total number of ports in the subscriber units. Each

subscriber module has the same number of 2 Mbit/s ports (e.g. AXE and EWSD modules

have the same amount of four modules); therefore the number of ports for connection of

transmission lines with the subscriber units in the local switch could be easily determined

knowing the total number of subscriber modules.

The number of ports, which are used for connection of transmission lines with other local or

transit switches, is conditioned by BHE directed to these switches. BHE designated for these

ports is calculated by multiplying the BHE part designated for the ports for the connection of

transmission lines with the subscriber modules by routing factors. The routing factor in the

current case is the average number of local switches used for the completion of a call. The

number of ports used for connection of transmission lines with other switches is calculated

according to the First Erlang Model. This statistical model calculates the number of

transmission channels according to the call traffic and the possibility of network overload.

One 2 Mbit/s transmission line consists of 31 transmission channels for the call traffic and

one transmission channel for the synchronizations. The statistical matrix used for the

calculations is designed according to the engineering assumption and consists of the columns

where probability of overload is reflected and the lines where erlangs are stated. The field of

the matrix shows the number of necessary changes in the transmission line. Less than 1

percent probability of overload maximum available traffic in 2Mbit/s transmission line is 21

erlang. The number of local switches is calculated by dividing the total number of ports from

the maximum number of ports in the switch.

14

2.1.6 Transit switches

The number of 2 Mbit/s ports used for the transmission lines among the switches is

determined by the BHE among the switches. Transit switches are connected only to other

switches (there is no direct access among the subscriber units and transit switches). An

assumption concerning the transit switches:

� transit switches are directly connected to at least one switch;

� transit switches are directly connected among each other;

� transit switches are directly connected to all other operator networks.

As well as in the local switches, the number of ports used for the lines connected to other

switches is determined by the BHE traffic directed to these switches. BHE designated for

transit switch ports is equal to the call traffic in subscriber units or in the connection to other

network points multiplied by the routing factor. In the current case, the routing factor is the

average number of transit switches used in one call.

The number of transit switches is calculated by dividing the total number of ports from the

maximum number of ports in the switch.

2.1.7 Busy hour call traffic

The major task in determining the capacity of switching network equipment is BHE

estimation. BHE is calculated according to operator statistics based on charged call minutes.

The following assumptions have been made:

Call traffic assumptions

Call traffic assumptions have a great impact on the final BU-LRAIC results. These

assumptions are about:

� call duration and dialing duration ratio;

� successful and unsuccessful call ratio;

� call duration.

The necessary data is extracted from the operator statistics, core network characteristics or

analyzing the sample part of call traffic.

Demand dimensioning

Infrastructure of the core network is designed according to the future market demand. It is

essential for the design to describe the period, for which design of the core network is being

15

made. It is done by comparing short-run surplus costs with the core network upgrade costs,

which occur when network is upgraded right then when there is a need.

Description of call traffic distribution throughout the day

Switching network infrastructure is designed according to the BHE. BHE is calculated using

the statistics of the average network traffic and the statistics provided by the operator about

call disperse throughout the time.

BHE is calculated according to the formula below:

60365 21 ffV

2.1.8 HY-LRAIC switching network topology

The schema of HY-LRAIC model efficient switching network topology ir presented in the

chart below. Note that any changes in HY-LRAIC model related to network modeling inputs

would result in different switching network topology from the one presented below.

17

Chart 3. HY-LRAIC switching network topology

2.1.9 Switching network cost estimation

After the description of switching network, its capacity cost may be estimated. Separate

elements of network equipment have a sophisticated structure. For example, a switch can

have different elements: „Line Interface Card“, „LIC Magazine“, „Port“ „Magazine“, etc.

Each of them has individual functionality and is influenced by the traffic.

Algorithms are constructed according to the network elements architecture; afterwards the

content of each network element is determined.

Investments in one part of the element are multiplied by the required number, thus the

necessary investment incremental costs are identified.

Costs of switches do not reflect the total costs of switching network. Switching network

management system costs are included into the model using benchmarks.

18

2.2 Transmission network

Based on the results of TD-LRAIC model analysis performed within the process of HY-

LRAIC model formation, it can be stated that TD-LRAIC and BU-LRAIC models do not

significantly differ with respect to the transmission network costs attributed to final cost

objects.

Consequently, HY-LRAIC model used the data of TD-LRAIC model. It ensures higher

explicitness of HY-LRAIC model, correspondence to the real situation and comparability

with the TD-LRAIC model prepared by TEO.

2.3 Cables and ducts

During the TD-LRAIC model analysis it was established that there are no essential unit value

differences (calculating 1 km) between the cables and ducts in BU-LRAIC and TD-LRAIC

models. The essential difference identified is the total length of cables used in the models.

In the HY-LRAIC model formation process, a hybrid algorithm for establishing the total

model cable length was created. Based on this algorithm, the actual transmission copper cable

length used in TD-LRAIC model is adjusted by a certain factor thus eliminating the effects of

copper cable length redundancy in the routes.

The above factor is calculated based on the following assumptions:

� On average, on the same cable route a defined number of remote concentrator units is

connected to the switch;

� Distances between all remote concentrator units on the same rout are the same.

Based on these assumptions, the following can also be calculated for comparison purposes:

� Number of different incoming cable routs (units per local switch are divided by

unites per route);

� Angle between different routes based on an assumption that distances between them

remain the same (angle of 360 degrees is divided by the number of incoming).

2.4 Intelligent network

HY-LRAIC model uses the intelligent network cost accounting principle applied in TD-

LRAIC model – this type of costs is included and distributed to cost objects as separate

19

independent HCC. In BU-LRAIC model, this type of cost is accounted for using the

benchmarks and proportional (to accrued costs) cost allocation methods.

Application of TD-LRAIC principles in the intelligent network cost case ensures higher

explicitness of HY-LRAIC model, correspondence to the real situation and comparability

with TD-LRAIC model prepared by TEO.

2.5 Other network and general purpose equipment

The following groups comprise the groups of other network and general purpose costs:

� Sales accounting system;

� Land and buildings;

� General purpose equipment;

� Network management systems;

� Other core network equipment;

� Access network equipment;

� Leased lines equipment.

Based on the results of TD-LRAIC model analysis performed in the process of HY-LRAIC

model formation, it can be stated that TD-LRAIC and BU-LRAIC models do not significantly

differ with respect to other and general equipment costs attributable to ultimate cost objects.

Consequently, HY-LRAIC model used TD-LRAIC model data. It ensures a higher

explicitness of -LRAIC model, compliance with the real situation and comparability with TD-

LRAIC model prepared by TEO.

20

3 OPEX

OPEX cost levels in BU-LRAIC and TD-LRAIC models were approximately the same and

did not constitute essential differences between the two models. Since actual data is used in

TD-LRAIC model (in BU-LRAIC model this part of costs is evaluated using benchmarks)

and in order to ensure that HY-LRAIC compares better with TD-LRAIC model prepared by

TEO, HY-LRAIC model used operating cost information of TD-LRAIC model.

21

4 HCC COST ALLOCATION TO NETWORK ELEMENTS AND

ACTIVITIES

In HY-LRAIC model, HCCs are attributed to network elements in the same proportions as in

TD-LRAIC model HCCs are attributed to network products and other activities.

The following cost groups constitute exceptions from this general rule:

1. Subscriber units – subscriber unit costs distribution between access and core network

element groups is based on BU-LRAIC calculated proportions (by traffic and access

increase costs). Subsequently, in cost allocation TD-LRAIC calculated proportions

are used for separate network elements.

2. Local and transit switches – local and transit switch costs are distributed to traffic

(BHT), call (BHCA) and general purpose network element groups based on BU-

LRAIC calculated proportions (according to respective engineering model results),

and internally – based on TD-LRAIC calculated proportions.

3. Common administrative costs – when allocating costs of this group, adjusted TD-

LRAIC proportions are used by taking a part of sales related general administrative

costs out of network elements intended for network equipment in proportion to

accrued costs. Sales activities administration costs are accumulated in a separate

network element.

22

5 ALLOCATION OF NETWORK ELEMENTS TO COST OBJECTS

When allocating network elements to cost objects, the same principles were applied in HY-

LRAIC model as in TD-LRAIC model. The main two differences between the calculations

made in TD-LRAIC and HY-LRAIC models is evidenced in:

1. The case of call set-up service distinction, since all the call set-up related costs in TD-

LRAIC model were not attributed to one call set-up cost object.

2. Point of interconnection on local level cost calculation, as the calculated cost of local

POI in TD-LRAIC does not reflect the total cost of local POI and reflects only the part of

the cost, which is related to capacity to provide local POI service.

In HY-LRAIC calculations, the following cost groups are allocated to call set-up cost object:

intelligent network (and related costs), billing system (and related costs) and signalization

equipment costs.

Thus, billing systems (and related costs) and signalization equipment costs, which in TD-

LRAIC model were distributed among all cost objects, in HY-LRAIC model were attributed

to call set-up cost object. In the case of intelligent network costs, modeling is based on

arguments that call completion in TEO network should determine the same utilization of

intelligent network resources as on-net calls in TEO’s network. When developing HY-LRAIC

model, the costs related to the intelligent network included in the call set-up, equal to number

portability costs calculated in TD-LRAIC model for local calls in TEO network. The model

also provides for a possibility to calculate the call set-up intelligent network costs based on

an assumption that all the costs related to this platform are distributed equally among all

successful calls in TEO network (i.e. in proportion to the number of successful calls).

With no information on actually incurred cost, because there are no alternative operators

interconnected on local level, the cost of local POI service in HY-LRAIC is calculated on the

assumption that technological process of POI service is the same both on local and national

levels. In this case, the annual service unit costs should be equal, i.e. the annual cost of one

local POI is equal to the cost of one national POI.

The cost of interconnection at all local POIs should not exceed the cost, which would be

incurred by an efficient operator. Difference between actual and modeled number of POIs, is

taken into account using the following formula:

fakt

efektefektfakt N

NSS

�� ;

23

where:

efektS - the cost of one local POI for efficient operator;

faktN - the number of actual POIs on local level;

efektN - the number of local POIs in efficient network.

The measurement unit of origination, termination and transit cost objects is minute, therefore,

the costs of these object units are calculated per minute. Meanwhile, the call set-up cost

object measurement unit is a call, thus in HY-LRAIC model, the unit costs of this cost object

are calculated per call. The measurement unit of cost objects of local and national points of

interconnection is the point of interconnection. The measurement unit of the capacity in point

of interconnection is 2 Mbit/s port.

The cost of signaling, sinchronisation, number portability, CPS and CS is included in the

cost of interconnection services (including call set-up), modeled in HY-LRAIC model.

Local switch dimensioning principles are stated in the scheme below:

Scheme 4. Dimensioning of the local switches (see scheme 2 for legend labels)

The number of local switches is dimensioned according to the following three parameters:

� The number of local switches necessary to meet the port demand;

� The number of local switches, necessary to meet busy hour traffic demand;

� The number of local switches, necessary to meet subscriber line demand.

43

Scheme 5. Number of switches according to the number of lines (see scheme 2 for legend labels)

Number of switches is estimated according to the number of analogue BRA, digital PRA and

capacity of switch and its utilization rate.

Busy hour call attempts

Principles for calculating the number of switches required to meet BHCA demand are stated

below:

Scheme 6. Number of switches according to the BHCA (see scheme 2 for legend labels)

The number of local switches is calculated by calculating the demand for processor

equipment caused by the BHCA. The following call attempts are measured:

� BHCA generated by subscribers;

� interconnection BHCA;

� Internet (dial-up) BHCA.

The number of local switches is calculated by the following procedure:

44

� first, a processor is dimensioned for each different type of BHCA according to

BHCA and its routing factors;

� second, the demand for processor equipment is calculated;

� third, the number of switches is estimated based on the demand, capacity per one

processor and processor capacity utilization rate.

Number of ports

Principles used for estimation of switches required to meet the demand for ports are stated in

the scheme below:

Scheme 7. Calculation of the number of local switches according to the number of ports (see scheme 2 for legend labels)

The number of ports is estimated according to the following:

� subscriber facing ports;

� network facing ports.

45

The number of subscriber facing ports is estimated according to the number of analog and

digital BRA, PRA lines (one port meets 4 line cards):

� the number of ports for analog and digital BRA lines is calculated according to the

fact that one port meets 4 line cards;

� the number of ports for digital PRA lines is calculated acoording to the fact that one

port meets 120 PRA lines;

� the number of ports for V.5.2 connections is calculated by dividing the total traffic

generated in digital and analog lines by 212.

Network facing ports are divided into three groups:

� transit switch facing ports;

� interconnection facing ports;

� internet facing ports.

Internet facing ports are estimated according to the following procedure:

� first, according to the BHE data and routing factors, the traffic on network facing

ports is estimated;

� second, traffic on one transmission link is estimated;

� third, according to the traffic on one transmission link and possibility of overload, the

number of transmission link channels is calculated;

� fourth, according to port capacity and routing factors, the number of ports required to

transmit the traffic through one transmission link is calculated;

� fifth, the total number of network facing ports is calculated.

The calculation procedure includes estimation of on-net BHE, interconnection points BHE

and internet BHE generated. The port demand is calculated by estimating the possible

number of swithes that ranges from 7 to 15.

principles as in the case of local switches. The only difference is the usage of numerical

values of routing factors, because only traffic in transit switches has to be taken into account.

Busy hour traffic. The number of transit switches necessary to meet BHCA demand is

estimated using the same principles as in a case of local switches.

6.2.7 Worksheet „EWSD LRAIC traffic“

In the MS Excel worksheet „EWSD LRAIC traffic“ incremental costs caused by increased

traffic are calculated. Incremental costs are calculated for the following components:

� subscriber units;

49

� local switches;

� transit switches.

Revaluation of subscriber unit incremental costs:

� calculations are made according to the following principle –costs of the network

elements calculated in the „Network nodes access“ are subtracted from the network

composition part costs calculated in the „Network nodes“;

� „Network nodes“ indicate costs of the network elements according to the current

number of subscriber lines and traffic generated;

� „Network nodes access“ indicate the network element costs if the number of

subscriber lines remains the same but the traffic is equal to 0;

� the difference of the costs reflects the traffic incremental costs.

Costs of the local switches are influenced by the call traffic, therefore all the switches costs

are considered as the incremental costs. In order so separate the cost set-up and cost duration

costs, it is necessary to distinguish, which parts of the switches are influenced by the quantity

of calls and which parts are influenced by the duration of the calls. In the table below all the

switch constituents cost groups are stated:

Scheme 10. Logical routing matrix scheme

Detailed calculations of the routing matrix are done in the MS Excel worksheets „Minutes“,

„Dimensioning“, „Routing“, „LS“, „TS“, „SU“. The results are displayed in the worksheet

„Results“.

Dimensioning is done by using matrixes; all the matrixes used in the models are of the same

shape.

6.3.1 Worksheet „Minutes“

The worksheet is designed for the primary information on the call traffic in order to enter the

numbers of minutes. The worksheet consists of two tables described below.

Table „Minutes“

The table is a minute matrix; its lines indicate different call set-up and the columns – call

termination locations. Crossing fields are the filed with the data on yearly call traffic

expressed in minutes.

The data in the model is the entry data used in the further model development.

Table „Diagonal matrix“

The table is a diagonal matrix with all cells equal to 0 excluding the figures in the matrix

diagonal from the left to the right, which have the meaning of 1. The diagonal matrix is

designed for estimation of one switch traffic part in the total traffic.

59

6.3.2 Worksheet „Modeling“

This worksheet is designed for the minute matrixes dimensioning according to the number of

local switches in the network. It is done by decreasing the number of local switches from 31

to 7. The results of every stage are saved in the field below the original matrix fields.

All the dimensioned matrixes (along with the interim calculations) are situated in the

worksheet in two columns:

� „Minutes“ – the column contains the matrixes with the data reflecting a change of the

local switch number, but does not reflect call traffic increment per call set-

up/termination location;

� „Adjusted minutes “– the column contains the matrixes with the data reflecting a

change of the local switch number and growth of call traffic per one call set-

up/termination location.

In the highest positions, minute matrixes with the highest number of dimensioned local

switches are placed. By going down the column, the number of switches decreases.

The „Minutes“ column data is used for the traffic part in one switch estimation. The

„Adjusted minutes“ column is used to dimension the number of minutes per network

elements.

6.3.3 Worksheet „Routing“

The worksheet contains the following matrixes:

� local switch;

� transit switch;

� remote units.

The fields of routing matrixes display data on usage of separate network elements according

to the location of call set-up/termination.

6.3.4 Network element worksheets

Network element sheets in the Routing matrix modes consist of the following worksheets:

� „LS“ – Local switches;

� „TS“ – Transit switches;

60

� „SU“ – Subscriber units.

Network element worksheets are designed to dimension the number of minutes per

appropriate network element.

The number of minutes per appropriate network element is calculated by multiplying the

adjusted minutes in the minute matrix from the worksheet „Dimensioning“ column by the

network element routing factors calculated in the column „Routing“.

The number of minutes per appropriate network element is calculated according to the

number of local switches in the core network. It is done by multiplying the same network

elements routing matrix by the minute matrix, which reflects the appropriate number of local

switches. In the highest positions of the worksheet, matrixes reflecting the highest number of

local switches are placed, by going down, the number of local switches decreases.

6.3.5 Worksheet „Summary“

The worksheet is designed to display the following results:

� traffic operated in one local switch;

� number of erlangs per network element.

Worksheet columns indicate:

� network elements;

� part of call traffic operated in one local switch;

� part of the traffic operated in more than one local switch.

Lines of the worksheet indicate the number of local switches in the core network.

The number of minutes per network element is dimensioned by summing up the appropriate

network element matrix figures in the appropriate element sheet.

Traffic operated by one local switch is dimensioned by dividing the sum of minutes matrix

figures (worksheet - „Dimensioning“, column – „Minutes“) multiplied by the appropriate

diagonal matrix figures by the sum of the same matrix field figures. In other words, it is the

ratio between the sum of figures in the minute matrix diagonal and the sum of all figures in

the same matrix.

„HCC“, „Data“, „Results“ worksheets are designed to aggregate BU-LRAIC HCC cost

categories and network products into more aggregated groups, which, when certain

classification is applied, can later be compared to TD-LRAIC model‘s aggregated groups.

„HCC“, „Data“, „Results“ worksheets with all the data were transferred directly from BU-

LRAIC model. The information from these worksheets, after some aggregation is performed,

is transferred to the „Simplified BU-LRAIC model“ worksheet. The structure of „Simplified

BU-LRAIC model“ worksheet is described in detail in chapter 6.5.3.

Aggregated information (from BU-LRAIC and TD-LRAIC models) from the main

reconciliation model is transferred into the second part of the reconciliation module of HY-

LRAIC model. Based on the analysis of the differences in both models, the aggregated

simplified TD-LRAIC model is used for the explanation of the differences.

The differences between the two models are explained on separate worksheets with certain

corrections to the aggregated TD-LRAIC model. On the bottom of each correction worksheet

the assumptions for particular correction are presented. Correction worksheets are related in a

way that the final results after every previous correction are transferred into the next

correction worksheet so that all adjustment worksheets are linked. In this way the connection

between the corrections is maintained.

After all the corrections are performed, the results of the impact of the corrections on the cost

objects are presented – the impact of each correction on the final cost of cost objects on

average, in LTL cents and on the other worksheet of the results – cost of cost objects in peak

time, in Euro cents.

� Weighted useful life times of separate aggregated asset (CAPEX HCC) groups – used

for assessment of annual depreciation costs.

� Weighted ratios of net book value and gross book value (NBV/GBV) of separate

aggregated asset (CAPEX HCC) groups – used for the level of non-depreciated

assets.

� Asset price change indices by separate asset groups – used for the calculation of asset

storage income (loss).

BU-LRAIC model calculation principles and their realization in MS Excel software are

described in BU-LRAIC model documentation.
