Chapter 1 — Provisionin
Introduction
This chapter out lines the procedures required to determine equip ment
requirements.
Provisioning a new system
Provisioning a new system consists of:
• Defining and forecasting growth.
• Calculating num ber of trunks required.
• Calculating num ber of lines required.
• Assigning equipment and preparing an equipment summary.

Forecasting trunk and line growth
The first step i n provisioni ng a new system is to forecast t he number of trunks
and lines require d at two-year and five-year interva ls .
The number of t runks a nd line s re quired whe n the system i s pla ced i n serv ice
(cutover) is determined by the customer. If the c us tom er is unable to provide
a two-year and five-ye ar growth forecast, then an estimate of an nual growth
is used to e stimate the number o f trunks and line s required a t the two-y ear and
five-year intervals.
Calculating number of trunks required
Enter the quantity of each type of trunk required in Worksheet A. This
determines t he number of trunk cards required at cut over, two-year, and
five-year intervals.
Calculating number of lines required
Enter the quantity of each type of analog and digital line required in
Worksheet B. This determines the number of Meridian Digital Telephone
TNs and Analog (500/2500 ty pe) TNs required at cutover, two-year, and
five-year intervals.

Conference channels
The conference function is provided by the NTMW01 Small Syste m
Controller (SSC) card. Two conference circuits are always active, a third
becomes active when the expansion cabinet is equipped.
Each conference cir cuit supports 16 conferees. Therefore the SSC card
supports a total of 32 conferees.
The Fiber Expansion Daughterboard supports an a dditional conference
circuit. Therefore a total of 48 conferees are supported when the SSC card is
equipped with a Fiber Expansion Daughterboard.

Chapter 2 — Transmission parameters
Introduction
The Meridian 1 Opti on 11C Com p act system uses µ-Law companding to
convert signals from analog to digital and from digital to analog.
Transmission characteristics are given in this chapter. Except where indicated
otherwise, the design objectives given are met when measured between 2
wire and 4 wire analog input and output interfaces terminated with their
nominal impedance.
The reference frequency is 1024 Hz. The reference level is -10 dBmO (as an
alternative a reference level of 0 dBmO may be used).
Transmission
Loss Plan
Insertion loss
The insertion loss of a private branch exchange (PBX) conn ection is defined
as the differen ce between the power del ivered from the (test) re ference source
into the input port and the power at the output port. For insertion loss tests
both the signal source and the measurement ins trum ent have impedances of
600 ohms. The test frequency is 1024 Hz.
The insertion losses between various Peripheral Equipment (PE) ports are
connection - specific in order to be compatible wit h end-to-end network
connection loss requirements. The Op tion 11C Compact loss specifications
are in ag r eement with North American standards, which are for mulated to
provide satisfactory end-to-end performance for connections within private
networks and between private and public networks.
Meridian 1 Option 11C Compact Technical Refer ence Guide
Page 12 of 136 Chapter 2 — Transmission parameters
The los s plan strategy fo r PE combines electrical loss with terminal acoustic
parameters for optimum transmission performance. For this reason, some
connections have asymmetrical loss in order to conform with network loss
plans. This asymmetry is resolved at a remote point (another switch) in the
overall connection.
Tables 1
, 2 and 3 provide loss values measured in decibels (dB) for
connections between:
• PE ports (lines and trunks)
• Digital ports (PRI or DTI)
Tables 1
, 2 and 3 are in matrix format; note the direction of the arrows when
searching for a lo ss v alue.

Input Impedance and Balance Impedance
Input Impedance for a port is the impedance as seen looking into the port from
the tip and ring.
The Balance Impeda nce is the output source impedan ce of the port and is
designed to match the impedance of the transmission line plus the far end
trunk.
