Introduction

System Capacities and Requirements

This section details the technical requirements and capacities of the system:
Hardware and software capacities for the system
Environmental requirements for placement of the control unit
Power and grounding requirements for operating the system
Capacities
The system can be arranged as a stand-alone system or as part of a private
network. Maximum system capacities are as follows:
Up to 108 simultaneous two-party conversations
Up to 80 line/trunk jacks, including loop-start, ground-start, DID, and tie
Up to 255 station endpoints that support a combination of the following:
— Up to 144 physical station jacks for telephones and adjuncts
— Up to 127 logical digital data ports (via 7500B Data Modules
System call-handling capability of 3888 hundred call seconds per hour
(ccs/hr)
Up to three 100D DS1 modules
The system has a total capacity of 224 jacks (80 outside lines/trunks plus 144
stations); however, each MLX module station jack supports two logical
endpoints (station devices that can operate simultaneously and independently).
For example, an MLX telephone with a Multi-Function Module (MFM) plugs into
only one station jack, but the jack supports the telephone and the equipment
connected to the MFM (such as a fax machine or an answering machine).
In a similar way, although the 100D module has only one jack, it can serve up to
24 endpoints (emulated lines/trunks or PRI lines/trunks).
Thus, the entire system can be configured to connect up to 80 lines/trunks and
255 station endpoints, a total of 335 endpoints.
NOTE:
The system has a time-slot capacity of 216. If more than 216 endpoints are
in use at the same time, blocking can occur.
