Introduction to SUB / SUB unit


Chapter 2

Introduction to SUB / SUB unit

Channel Unit SUB / SUB belongs to the DYNANET family of equipment.SUB / SUB refers to the subscriber interface end of the transmission path (asopposed to the exchange end). The unit simulates the functions of an exchange tothe subscriber and controls the functions for the exchange signalling.

SUB / SUB units can be used in the following applications:

D in ordinary telephone networks

S to connect subscribers to a digital exchange directly at the 2048 kbit/sinterface (see Figure 1)

S to connect subscribers to an analogue exchange via a SUB / EXCH unit

(see Figure 2)

D in hot line applications (see Figure 3).

S CEPT A type mechanical structuresS 19 mechanical structures, for example DYNANET subrack

D compliance with ITU-T Recommendations G.712, G.713 and Q.552.

The unit has the ability to key the ringing signal. As this is the most efficient modeof operation for minimal power dissipation, it is recommended to configure thering generator for keyed operation if the following conditions are met:

D the ring generator used and the other channel units configured in the same

subrack support keyed operationD each subrack has its own ring generator.

If several subracks or cartridges share a ring generator, using the same rack bus, setthe ring generator for continuous operation. This is necessary because the controlsignal to key the generator is local to the subrack backplane and it is not passed onto the rack bus.

About this document

This document gives the instructions on installation and cabling of Channel UnitSUB / SUB (Subscriber unit / Subscriber end). In this document, the unit will bereferred to as the SUB / SUB. The following topics are covered:

D Precautions (Chapter 2)D Work order (Chapter 3)D Checking power supply and mechanical installation (Chapter 4)D Connecting jumpers (Chapter 5)D Connecting cables (Chapter 6).

SUB / SUB units cannot function on their own and, therefore, they are alwaysinstalled as a part of a larger system. SUB / SUB units are always operated and

controlled by the main unit of DM 2 or DM 2+. In this document, both equipmentare referred to as DM 2.

If the SUB / SUB unit is to be installed in a subrack that has already been set upcorrectly (for instance, as a replacement to a faulty SUB / SUB unit), it is onlynecessary to ensure that the configuration jumpers for the ringing voltage and lineimpedance settings are correctly positioned (see Chapter 5). No other hardwareconfiguration will be necessary.

Checking mechanical installation and power supply


Chapter 4


This chapter lists the preliminary inspections you should make on mechanicalinstallation and power supply before starting to set up a new DM 2 system thatincludes SUB / SUB units. If you are installing the unit as a replacement to a faultySUB / SUB unit, you can skip this chapter and continue from Chapter 5.

4.1 Mechanical installation

The SUB / SUB unit can be installed into CEPT A type or 19 mechanicalstructures, in any unit location. The dimensions of the SUB / SUB unit are 6Uhigh by 5T wide.

If you are setting up a completely new DM 2 system that contains SUB / SUBunits, check the following:

D Make sure that the subrack into which you are installing the units isundamaged.

D Make sure that the subrack or cartridge has been correctly installed (forsubrack installation, please refer to the subracks own installation manual).

D Make sure that the main unit has been installed correctly (for instructions,please refer to DM 2-MUX Operating Handbook or DM 2+ Operating

Manual).

4.2 Power supply

If you are setting up a completely new DM 2 system that contains SUB / SUBunits, check the following:

D Make sure that the rack has been properly earthed.

D If you want to use other kinds of channel units in the same setup as theSUB / SUB unit, make sure that the units are compatible with each other inthe area of voltage requirements.

7/30/2019 21206 (C33561.20 B0) User Manual

34/130



D Make sure that the following supplies are available in the subrack:

S battery voltage: 20 to 72 VS signalling voltage

B1: 43 to 58 V (nominally 48 V) with reference to ground

B2: 30 to 43 V with reference to groundS ringing voltage: approximately 75 V, 25 Hz.

The ringing voltage can be generated in a ring generator within the subrack or itcan be brought to the subrack from a central ringing source that is shared betweenseveral DM 2 setups.

The voltages are delivered to the SUB / SUB unit via the units back connector,PB1. The unit connects automatically to the voltages and to the subrack groundwhen it is plugged in the subrack.

Signalling voltages

B1 is the signalling voltage which generates the current for subscriber loop. In theunit TU 21206 the signalling voltage is 48 V (58 to 43 V).

The B2 signalling voltage 36 V (43 to 30 V) is optional and it is not necessaryfor operation of the unit. If the B2 signalling voltage is connected, the unitautomatically selects the lower signalling voltage for short subscriber lines. In thiscase the power dissipation in the unit is lower.

No separate signalling voltage is needed if the central battery voltage is in therange of43 to 58 V.

The positive pole of the battery voltage and the positive pole of the signalling

voltage must be connected to the subrack body even if the signalling voltage isbrought from outside of the system.

Using central battery voltage as signalling voltage

Normally the central battery voltage is 48 V whereupon it can be used assignalling voltage. In this case VNB (negative pole of the central battery voltage)and signalling voltage B1 are connected together.

Because the ground of the signalling voltage is connected in the unit to unitsground and further to the subracks body, the positive pole of the signallingvoltage source must be connected to the earthing of the rack/subrack. You should

also take this into account when you use the central battery voltage as signallingvoltage.

Ring trip

Ring trip detection is provided by connecting the signalling voltage in series withthe ringing voltage. Detection takes place as DC current detection.

The ringing voltage can be connected in two different ways:

D Ringing with reference to negative (-) voltage (default)S Jumper settings: TU 21206 NR4=RG_ref=GNDS

Ringing voltage RG1 of ring generator is connected to signalling voltageB1 (48 V).

7/30/2019 21206 (C33561.20 B0) User Manual

35/130



D Ringing with reference to positive (+) voltageS Jumper settings: TU 21206 NR4=RG_ref=B1S Ringing voltage RG1 of ring generator is connected to ground (GND).

(This jumper setting is possible to do in the ring generator of version08A or newer.)

NoteAll TU 21206 units fed by the same ring generator must have the jumper settingNR4 connected.

Connecting jumpers


Chapter 5

Connecting jumpers

Caution

Take standard anti-static precautions (such as a wrist strap earthed to the subrack)when handling the SUB / SUB unit, as it contains components which may bedamaged by static discharge.

Caution

Set the jumpers on the SUB / SUB unit before installing the unit into a subrack. It ispossible to cause damage to the SUB / SUB unit if the jumper settings are notcorrect.

The following jumpers have to be connected on the SUB / SUB unit:

D NR4 for ringing voltage reference (affects all channels)S ringing about groundS ringing about signalling voltage

D NR1, NR2, NR3 for line impedance (separately for each channel)

S 600 WS 270 W + (750 W // 150 nF).

5.1 Ringing voltage reference configuration

You may configure SUB / SUB units to use a ringing voltage about rack ground orabout the signalling voltage (48 V nominal). To configure the ringing voltage

reference, do the following:D On the SUB / SUB unit, configure jumper NR4. The setting affects all

channels.

D On the power supply unit, configure the ringing voltage reference line (RG1).

NoteThe RG1 connection at the power supply configures RG1 for all subracks orcartridges supplied by that power supply.

If NR4 is set up incorrectly for the ringing signal connected to the SUB / SUB unit,then premature ring trip may occur. For this reason you should take care whenusing a mix of compatible channel units in a DM 2 setup. All the units should be

capable of working with a ringing signal referenced about the same voltage andthe ringing signal should be configured accordingly.

Accessing and controlling SUB / SUB


Chapter 2

Accessing and controlling SUB / SUB

All software-configurable parameters for the unit are accessed via the serviceinterface of the main unit of DM 2-MUX or DM 2+. The main unit provides themenus related to the common parts of the equipment, and the SUB / SUB unitprovides menus relating to its own operation.

The SUB / SUB units are accessed and controlled using a Service Terminal orMacro STE (Service Terminal Emulator).

To access the SUB / SUB unit

D Connect, with an interface cable, the Service Terminal to the main unitsservice interface connector. If you are using the Macro STE, connect your PC

to the PC interface connector.

D Switch on the Service Terminal or start the Macro STE. After a few seconds,the top level menu that is common to all equipment is displayed.

D Establish a direct connection to DM 2: OBJ 7 RET. After a while, the main menuof DM 2 appears on the screen.

D Choose the type of function you want to access (for example, Settings) in themain menu.

D Choose number 9 in the subsequent menu.

D Choose the unit by typing in the number of unit slot in the subrack. Thesubrack slot numbering starts from the left of the subrack.

If the selected unit slot is empty or houses a MUX unit instead of a SUB unit, youwill get the following response:

No tributary unit

in this location

If a unit has been taken out from the subrack and the equipment configuration hasnot yet been modified with a software command, the response below will be given.You will get the same response also if the selected unit location contains aninoperative unit.

Missing unit in

this unit location

After you have selected the unit, the SUB / SUB menu for the type of function

selected (for example, Settings) appears on the screen.

Configuration dependent entities in the command strings are represented byabbreviations (listed in Service Menu Reference of this manual). You will have toreplace the abbreviation by a proper value when keying in the command.

NoteIf the Service Terminal is left unused, it will disconnect and switch offautomatically after a specified time-out has elapsed (the default time-out is 10minutes).

Commissioning SUB / SUB


Chapter 3


The following describes the steps necessary for commissioning a SUB / SUB unit

for normal operation in a DM 2 system. This chapter deals only with the softwareconfigurable parameters and is divided into the following sections:

D commissioning procedure for replacing a damaged unitS with the settings of the old unit restored to the new unitS without restoring the settings of the old unit to the new unit

D commissioning procedure for configuring a unit in a new DM 2 system.

Before configuring the software, make sure that the jumper settings for ringingvoltage reference and line impedances have been set correctly (seeInstallation inthis manual).

If you request the commissioning of a unit that is already in the commissionedstate, then its current configuration is copied to the next unit in the cartridge. Thisallows the configuration back-up of the unit to be kept up-to-date if changes aremade to its settings.

NoteCommission a configured unit only when all of its channels are idle. Thecommissioning process will terminate any calls that are currently in progress.

3.1 Replacing a damaged unit

There are two alternative ways to do the replacement depending on whether youwant to restore the settings of the old unit to the new unit or not.

NoteRemove only one unit at a time. When a new unit is inserted in the subrack,back-up copies are exchanged between the units next to each other. To make surethat this is done successfully, let the equipment stabilise for about 2 minutes beforechanging the next unit.

56/130



3.1.1 Restoration of settings

When this procedure is used, the new unit will have the same settings as the oldone. This procedure can be used only if the Hardware ID of the new unit is thesame as the one of the old unit.

1. Disconnect the signal cables and pull out the damaged unit from the subrack.2. Insert the new unit in the same unit slot and connect the signal cables.

3.1.2 No restoration of settings

When this procedure is used, the new unit will have all settings at their defaultvalues.

1. Remove the old unit from the configuration using the Remove unit command(6,2,2,u; u = number of unit slot in subrack).

2. Disconnect the signal cables from the damaged unit and pull out the unit fromthe subrack.3. Insert the new unit in the subrack.4. Issue the Add unit command (6,2,1,u; u = number of unit slot in subrack).5. Connect the signal cables.6. Make sure that the new unit works as intended.

3.2 Commissioning units in a new DM 2 system

The commissioning procedure consists of the following steps:

1. Configure the units in the DM 2 setup by the Install all units command.2. Set default settings.3. Set identifications.4. Set unit settings.5. Configure interfaces.6. Make sure that the new unit works as intended.

NoteIf you add a new channel unit to a partially complete DM 2 system which iscurrently in use, configure the unit using the Add unitcommand (6,2,1,u) ratherthan the Install all units command (6,2,3). Install all units command will terminateall calls currently present on the existing units.

3.2.1 Configuring units in a DM 2 setup

To configure all units in a DM 2 setup, enter:

TOP6,2,3RET Install all units

To verify that the SUB units are configured, enter:

TOP6,2,0RET Display

7/30/2019 21206 (C33561.20 B0) User Manual

57/130



To check that no errors were encountered while installing the new units, enter:

TOP1RET Fault display

If the fault display indicates a SUB / SUB power supply fault, check the following

points:

D Is the SUB / SUB unit correctly installed into the cartridge or subrack?D Are the connections for the voltages and grounding correct?

3.2.2 Setting default settings

If you have installed the unit with the 6,2,3 Install all units or 6,2,1 Add unitcommand, default settings for that type of unit should already be in use. If,however, you make a mistake during reconfiguration of the unit and start theconfiguration process again, you can restore the default settings for the unit using

the Set default settings command, 6,9,u,1,1.You can display all current parameters using the Display settings option, 6,9,u,0.

Commissioning the unit requires setting of some parameters. Many of theparameters are channel-specific, and many have default values (factory set),which may already be acceptable to you. The default settings are listed in Table 1.

Parameter Default setting

Voltage supervision Enabled for all three supervised voltages (signalling,5 V and ringing)

Channel use All channels out of use

Time slots Time slots set to 1 to 6 (for channels 1 to 6)

Wire levels for all channels 7.0 dBr in the receive and +0.0 dBr in transmitdirection

2-wire balance impedancegroup for all channels

Set to group 1: 600, 600

Channel blocking Disabled for all channels

Signalling mode Set to Normal for all channels

Metering use Disabled for all channels

3.2.3 Setting identifications

To help you in managing the unit, you can set an identifier for the unit. The otheridentifications are fixed and can only be displayed.

The identifier can be up to 15 characters long. Usually, it describes either thelocation or function of the unit.

To display the identifier, enter:

TOP4,9,u,2RET

To modify the identifier, enter:

TOP4,9,u,7,2,1RET

Note

When entering IDs using the Service Terminal, the alphabetic characters have tobe entered as hexadecimal integers, terminated by the ASCII key (characters from Ato F may, however, be entered as INV1...6). Spaces are not accepted but may besubstituted by underline characters. For further details and hexadecimal codes,refer to TC 21700 Service Terminal, Operating Handbook.

3.2.4 Setting unit settings

Voltage supervision

The unit supervises three voltages on the board:

D signalling voltage (48 V)D 5 VD ringing voltage (75 VAC).

Each of these individual voltages can be set supervised.

To set voltage supervision ON or OFF for the channels, enter:

TOP6,9,u,2RET

If supervision is enabled, a Power supply fault alarm will be generated if asupervised voltage exceeds its specified range. We recommend that supervision isenabled for all three voltages, as this will allow rapid detection of faults such as afailure in the ring generator.

The measurement circuitry for these voltages is calibrated at the factory, but ifnecessary, this calibration can be redone using the Voltages option (7,9,u,1). It isnot likely that the unit will require re-calibration, unless you have accidentallyaltered the calibration values.

Fault consequences

To specify the consequences of some fault conditions, enter:

TOP6,9,u,4RET

7/30/2019 21206 (C33561.20 B0) User Manual

59/130



This option sets the consequences of AIS or blocking. You can set the events tocause a B-alarm, or no alarm. Additionally, you can set blocking to leave thesubscriber line in either the Open state, or with reversed polarity feed applied.

3.2.5 Configuring interfaces

Each SUB / SUB unit can be configured either separately or by copying thesettings from another SUB / SUB unit. The settings can be entered separately foreach channel.

Wire levels

To set the wire levels, enter:

TOP6,9,u,3,3RET

This option sets the relative voice level on the subscriber interface lines.

2-wire balance impedance

To select a balance impedance most suitable for the speech wire interface, enter:

TOP6,9,u,3,5RET

This option sets the 2-wire balance impedance group for individual channels.

The 2-wire balance impedance should be selected for the closest match with theimpedance of the line plus terminating equipment connected to a channel.

Signalling modeTo set the subscriber line signalling to use either normal (back-to-back) or hot lineprotocol, enter:

TOP6,9,u,3,7,ch,RET

Metering use

To set metering ON on a subscriber line, enter:

TOP6,9,u,3,8,ch,RET

Time slots for channels

To allocate time slots to channels, enter:

TOP6,9,u,3,1, ch,3RET

You can allocate any time slot 1 15 or 17 31 to any channel. However, you mayfind it convenient to allocate channels to units in consecutive groups of six.Allocate consecutive time slots using the All channels option (6,9,u,3,3,11) in theSelect channel menu. Time slot 16 is used for signalling, and it will be skippedautomatically if you use the All channels option.

60/130



Channel use

Each channel of the unit can be set into use or out of use. The channel settings areretained also when the channels are out of use.

To set channels in use or out of use, enter:

TOP6,9,u,3,1,chRET

Channel blocking

Blocking can be used to take a line out of use temporarily, without affecting theother parameters of the channel.

To block a channel, enter:

TOP6,9,u,3,6,chRET

3.2.6 Checking the operational condition

Check operation

By connecting the 2-wire interfaces, make sure that the SUB / SUB unit is workingas intended.

Check fault indications

Check that the red and yellow LED both on the DM 2 main unit and on the SUBunit are OFF. The service LEDs indicate the following conditions:

Fault indications

RED Serious fault impairing the function of the equipment

YELLOW Exceptional condition in the equipment or unit, forexample, a loopback or other service function

GREEN Equipment or unit is accessed via a Service Terminal

Check the fault display for possible fault conditions. The fault display showsfaults in all units controlled by the DM 2 main unit. In the case of a fault, it shows

the faulty units ID, fault status and fault data.

To display faults, enter

TOP1RET

If no faults have occurred, the response is:

*DM2 (OK) (where DM2 is the identifier of the main unit)

If a fault has been detected by the main unit:

S check the equipment configurationS look for possible causes, for example, loopbacks set on.

Locating faults


Chapter 4

Locating faults

The SUB / SUB units do not require scheduled maintenance. Maintenance actionsare necessary only when a fault is indicated by means of an alarm.

This chapter lists some features that may be useful in finding out a cause of a faultin the operation of the SUB / SUB unit.

4.1 Rack alarms

The different alarm classes are:

A Prompt alarm

Generated by a fault which inhibits the normal operation of the equipment. AnA-alarm is always generated only by the equipment that has actually detected thefault (AIS or far-end alarm is sent to the other parts of the system as an indicationof an already detected fault). Immediate actions are usually required to return theequipment back to normal operational state.

B Deferred alarm

The equipment is still operational but the quality of the services provided hasdegenerated.

D Reminder of an alarm

In a fault situation, rack alarms A and B can be removed by giving the Local alarmcancel command. As a result, rack alarm D is given to remind of the cancelledalarm(s). When the fault has been repaired, the alarm indication functions arerestored to normal state by selecting Reset local cancel command.

S Service alarm

An S-alarm is generated when the equipment in the far end sends a far-end alarmor an alarm indication signal (AIS) is received. An S-alarm is also given when themain transmission channel is not available. Thus, the S-alarm providesinformation on the state of both transmission directions.

The difference between S- and A-alarms is that the S-alarm indicates a seriousfault in the operation of the main transmission path, whereas the A-alarm indicates

7/30/2019 21206 (C33561.20 B0) User Manual

62/130



faults on a certain channel (or channels), while other channels (services) may stillbe operating normally.

4.2 LEDsThe LEDs on the front of the unit provide some indication as to current activity ofthe unit, or the type of fault, if one is present.

The red LED indicates either that the unit has not yet been configured into theDM 2 system or that a serious fault has occurred in the unit. If the LED isindicating that the unit is not configured, the fault display does not indicate anyfault.

The yellow service LED indicates faults in the signal received by the unit, powersupply faults, or service conditions, such as loopback or blocking. The unit itself isnot usually at fault if the yellow LED is lit, as this alarm generally indicates either a

user-initiated service condition, or a fault in far-end equipment or cabling.

The green service LED is lit when the unit is accessed by the Service Terminal.

4.3 State and fault messages

The state and fault messages of the equipment obtained through the service menuoption 1 Fault display are described below. The rack alarm/service LED indicationin each situation is also given.

Locating faults


Power supply fault

One or more of the supervised voltages (signalling, 5 V or ringing) has exceededits specified range. Possible causes of this alarm are:

D failure of external signalling voltage supplyD partial failure of unit power supplyD failure of ring generatorD measuring circuitry out of calibration.

Channel blocked

One or more channels in the unit has been blocked from use via the serviceinterface or the unit is trying to use a time slot that is currently in use in anotherunit.

Loop to equipment

A loopback has been set up on one or more channels in the unit.

NoteA loopback will disconnect the traffic for a channel on which it is active.

Test mode

The unit has been put into one of the production test states, and thus cannotfunction normally.

AIS in TS 16

There is a fault external to the unit on the digital signal path or blocking has beenapplied from the exchange on a time slot allocated to the unit.

Equipment fault

A major failure of the unit. Faults such as EEPROM memory failure and unitpower supply failure are indicated by this alarm. If an equipment fault isregistered, it is probable that the unit will need to be replaced with a new one.

Installation error

The software version is incompatible with the hardware. The alarm is issued:

D when two units have accidentally been inserted in each others slots in thesubrack

D in the unusual circumstance when a new version of software is installed on anold version of hardware which it cannot control correctly.

Forced indication

One or more of the LEDs of the equipment have been set in a forced state (Forced

ON or OFF), and they are therefore unable to provide normal indication of alarmsor conditions until the forced state is removed.

7/30/2019 21206 (C33561.20 B0) User Manual

64/130



Unit not installed

The unit has not been configured into the DM 2 setup. This condition does notgenerate any alarm, but does cause the red LED to be lit.

Unit accessed via service interface

The unit is currently being accessed through the service interface.

4.4 Loopbacks

To help with fault location on the digital signal paths, a digital loopback can beconnected on the digital side of the CODEC (D-D loop). The loopback can be seton with command 5,9,u,2,ch,2.

Loopbacks and other controls operate on a timed basis. Set a time-out period using

command 6,9,u,6,1. After this selection, controls will continue to operate untilcancelled or until the time-out period expires. If you set the time-out period to65535, time-out will never occur.

4.5 Performance measurements

The unit can provide some (limited) performance or usage information using theTraffic andAlarms logs (7,9,u,5 and 7,9,u,6). These provide information on thenumber of calls processed, and the number of 2048 kbit line failure alarm eventsreceived by the unit. Both logs display a count of their respective events since theywere last reset.

The operating voltages can be checked by command 7,9,u,1. If the operatingvoltages deviate from the recommended values, it is advisable to check the batteryand the signalling voltage, and the connection between the positive pole of thesignalling voltage and the subrack ground.

4.6 Tests

For production purposes the unit has a set of test options, given in menu 9,9,u.Normally, you should not need to use this test facility.

NoteIf you enter a production test state accidentally (a rack alarm B, test mode, isgenerated), cancel the state with command 9,9,u,1,1.

The metering signal 12 kHz (charge indication) is active. If in the exchange endthe unit TU 21215 is used which does not support the metering function, thismetering function must be set out of use also in the SUB unit TU 21206 bycommand 6,9,u,3,8,ch,2.

NoteThis action concerns the SUB unit version 01A; in the unit version 03A thefunction is disabled by default.

Problem

In the hot line connection, a telephone gives a re-ring signal if both subscribershave not laid down the receiver exactly the same time.

ActionYou must set the hot line function into use by the Service Terminal command6,9,u,3,7,ch,2.

Problem

A new SUB unit in connection with an old EXC unit.

Action

When you use a new SUB unit (TU 21206 version 01A) together with an old EXCunit (TU 21215), the metering function must be set out of use.

In the new SUB unit version 03A this metering function is disabled by default.

In addition to this, in the old EXC unit the Ringing timing control setting (6,9,u,7)must be set to Direct timing (6,9,u,7,1).

NoteThe following question concerns the unit TU 21216.

Problem

The signalling is functioning normally but the voice is hardly to be heard.

Action

Unlike old units, the unit TU 21216 requires for its operation signalling voltage48 V. For this reason you have to connect the signalling voltage 48 V tosubracks B1. The positive pole of the voltage is to be connected to thesubracks/racks earth screw.
