This document is for you if you want to learn a bit more about how Meridian 1 – Option 81C PBX system works. This document will be good for those who need to know about the configuration of Meridian 1. A little bit telecommunication knowledge is required to go through this document.

This document has been made with the full reference of M1R25 document of Nortel Networks. So, thanks for the Nortel Networks.

Types of telephone systems

When telephones are required in a building for a group of users, there are several options from which to choose

There are three main types of systems are:

Centrex Key System Private Branch Exchange

Nortel Networks manufactures systems of all the three types.

The Nortel Networks system that servers Centrex telephones is called the DMS systems The Nortel Networks system that servers Key System telephones is called the Norstar systems The Nortel Networks system that servers Private Branch Exchange are called the Meridian 1 systems

PBXs, trunks, and Central Offices

PBXs provide telephone service to large numbers of users, usually between 30 and 10,000.When you are connected to a PBX and you lift the handset of your telephone, the dial tone you hear is coming from the PBX.

2

The PBX receives the digits you dial, interprets them and connects you to the destination you want. Sometimes the destination is an internal telephone, connected to the same PBX. Sometimes it is an external telephone connected to the PBX by a trunk.

Trunks are pairs of wires or optical fiber that connect the PBX to an outside system. One of these systems is called a Central Office. The Central Office (or CO) provides telephone service to businesses and residences in your local area.

Central Offices are sometimes called exchange offices. When your call goes out to one of these offices you have accessed the exchange network, sometimes called the public exchange network.

If you have more than one trunk connected to the same end-system, handling the same kinds of calls, arrange them in trunk groups (also called trunk routes). For example, trunks connected to the Central Office that handle public exchange network calls are called Central Office Trunks (COTs).

Analog and digitalThere are trunks that handle analog signals and those that handle digital signals. There are analog and digital PBXs as well as analog and digital telephones.

Analog signals are transmissions that travel along in a wave format. They might travel through a wire (when a signal is traveling along a trunk) or the air (when you are speaking to someone beside you).

Digital signals are on and off pulses put together in a particular sequence. The pulses and the sequence are deciphered by equipment at the other end that can either read the message and understand it digitally or change it into an analog format to be heard and understood by a person. When a telephone or system is called digital it means it is built to send and receive signals in a digital format.

The Meridian 1 is a digital PBX system

The Meridian 1 can be connected to both analog and digital trunks

System models

There are three distinct families or generations of PBX systems manufactured by Nortel Networks. The most recent generation is called the Meridian 1. The earliest Generation was called the SL-1, followed by the generation called the Meridian SL-1.Each generation has at least three models.

3

CONTROL

NETWORK

Each model is designed to handle different quantities of telephones. Generally, you can divide each generation into the categories of small, medium and large systems. In the most recent Meridian 1 generation there is also a system that handles a very small number of telephones.

MERIDIAN 1 HARDWARE

The hardware components of the system belong to three main groups of equipment.

Common Equipment (CE)

Network Equipment (NE)

Peripheral Equipment (PE)

5

COMMON EQUIPMENT (or) CONTROL EQUIPMENT

CALL PROCESSOR (CP)

The components in this area of the machine can be called the computer because they control the operation of the rest of the system.

Central Processing Unit (CPU) Memory Disks Input/output ports

The CPU performs the functions required by the telephones and trunks connected to the system.

The memory has all the instructions stored so the CPU can operate.

The disks have a permanent record of the instructions. If the memory is erased because of a power failure, for example, the instructions stored on the disk are automatically loaded into the memory when the power failure ends.

The input/output ports are called Serial Data Interface (SDI) ports. They allow your system maintainer to connect a terminal to the system for programming purposes. If you are going to move, add and change telephones, you will be using this terminal as well. Other devices, such as printers for traffic studies and call detail records, are also connected to these ports

Inter-Processor bus to communicate with in the Control Equipment

INPUT/OUTPUT DISK UNIT WITH CD- ROM (IODU/C)

Software is delivered to Meridian 1 systems by CD-ROM. IODU/C applies to Options 51C, 61C, 81, and 81C.

CORE NETWORK INTERFACE (CNI)

It provides interface between the inter-processor bus and the network shelves It provides interface between the Call Processor and the Three Port Extender (3PE) cards, each CNI can be connected to

two 3PE cards

NETWORK EQUIPMENT

The telephones and trunks interconnected by the PBX are connected using the Network Equipment components of the system.

6

Time slots

The system uses timeslots to connect each party on an active call. If two internal telephone users are speaking, the system uses two timeslots to connect them, one for each telephone. If a telephone user is calling out on a trunk, the system uses two timeslots, one for the telephone and another for the trunk.

Loops and Super loops

These timeslots are present on Network Equipment components called Loops. Each Loop has 32 timeslots, if it is an Enhanced or Standard Loop. Meridian 1 systems use Enhanced Loops. Meridian 1 systems can also use newer versions of Loops called Super loops. Super loops have 128 timeslots. Loops and Super loops are cards that sit in the Network Equipment area of the machine. A Virtual Super loop has been introduced in X11 Release 25 to support i2004 Internet Telephones. Up to 1024 telephones can be configured on a single Virtual Super loop for a system, compared to the traditional 512 telephones. Collectively, 32 loops are called a group. The Option 81C is called a multi-group system because you can equip up to five groups.

Introduced in X11 Release 25, Fiber Network fabric (FNP) allows the expansion of Meridian 1 Option 81 and 81C systems from five Network groups to eight Network groups, a 60% increase in port and trunk capacity. A Dual Ring fiber optic network has replaced the intergroup cards and intergroup module in pre-Release 25 Meridian 1 systems.

A Fiber Network provides 7680 timeslots for 3840 simultaneous conversations. This significantly enhances the number of telephones that you can configure on a system.

Network Controller cards ENET – Enhanced Network card (handles 2 network loops, max. 8 per N/W shelf), XNET –Super loop Network card (handles 1 super loop – equivalent to 4 network loops), max. 4 per network shelf)

Digital Trunk Cards DTI – Digital trunk interface (E1 for Europe, T1 for North America), PRI– Primary rate interface (PRI2 for Europe, PRI for North America)

Conference and Tone and Digit Switch CardsWhen you look at your system you will notice there are also Conference cards and Tone and Digit Switch (TDS) cards sitting near the Loop and Super loop cards. They are also part of the Network Equipment. The Conference card supplies extra timeslots to a conversation when additional people are added in a conference. The TDS card supplies tones like dial tone and busy tone, when told to do so by the computer in the system. On some systems, the Conference and TDS functions are combined on dual-function cards.

Peripheral Signaling provides buffering and signaling interface between CPU and peripheral equipment

Clock Controller Provides a stable clock reference for synchronization with the public network (PSTN); requires when system uses digital trunks

PERIPHERAL EQUIPMENT

Line cards and trunk cards

The telephones and trunks on your system are connected to the system with cards that sit on shelves. There are line cards for telephones and trunk cards for trunks.

7

On the newer Meridian 1 systems these shelves for cards are housed in modules.There are unique cards designed for each type of telephone and trunk. More than one telephone or trunk is connected to a card. The version of the card determines how many can be connected. When you add more telephones and trunks to your system, you will need to add more cards when the existing ones are fully utilized.

Density

A term, density, is used to describe, in general, the vintage and capacity of a card. For example, when line cards were introduced in 1975, they had four units on them to connect up to four telephones. These are called single-density cards. Later, line cards were introduced with twice as many units for twice as many telephones and these are called double-density cards. The development of new cards continued, with the introduction of quad-density cards that connect up to 16 telephones, and then octal-density cards. These have 32 units, 16 of which are for digital telephones and the other 16 are for associated data terminals that you can connect to the telephones.

PE cards vs. IPE cardsThere are two versions of cards:

Intelligent Peripheral Equipment (IPE) Peripheral Equipment (PE)

Meridian 1 systems can accommodate IPE cards and PE cards. Only upgraded SL-1 and Meridian SL-1 systems can handle IPE cards. If not upgraded, they can only have PE cards.

Intelligent line cards and trunk cards can have more telephones and trunks connected to them than the older, non-intelligent kinds of cards. This saves room in your system and keeps your system small.

XPEC- Controller card – performs protocol conversion between DS30Y (used in super loop side) and DS30X (comm.b/w xpec & ipe). Intelligent cards are served by Super loops. Non-intelligent cards are served by Loops.Other line cards placed in PE XALC, XDLC, XUT, LSE1 and XEM

Ring Generator - generates the electrical signal, which causes an analog set to ring

Digitone receiver (DTR)

If you use Digitone-type telephones, your system has digitone receiver (DTR) cards. Digitone-type telephones are sometimes called 2500 or DTMF telephones. They are analog telephones that out pulse tones when keys on the keypad are pressed.The CPU of your system requires assistance in interpreting these analog tones. The DTR card was designed to interpret these tones and change each tone into a digital signal, suitable for the CPU.You need DTR cards if your system has any Digitone-type telephones, or Digitone-type trunks which carry these tones into your system from other systems.

STIPULATION

The greater the number of Loops or Super loops equipped on your system, the greater the number of timeslots you have. As you add more telephones and trunks to your system it is important to keep the timeslots in mind.

If you do not provision sufficient timeslots, or manage the system properly, the users on your system might begin to complain of poor service. This usually appears first in the form of dial tone delay problems.

8

When users lift their handsets to make calls, it is called taking their telephones off-hook. The system attempts to provide dial tone to the telephone that is off-hook. Timeslots are needed in order to provide dial tone. An under-provisioned system will not have enough timeslots for the demand, especially during busy times of the day. If there are not enough timeslots available for dial tone, a user must wait until another user on the same Loop (or Super loop) hangs up. Since Super loops have far more timeslots than Loops, dial tone delays usually do not occur when you use Super loops on your system.

This demand for timeslots is called traffic. You can predict the expected demand with the help of your system supplier. The occurrence of service problems is sometimes called blockage. There are many things you and your system supplier can do initially, and on an ongoing basis, to eliminate blockage. Refer to the module called Traffic for many suggestions.
