Hardware and Software Capacities
You can configure the system as a stand-alone unit or as part of a
private network. Maximum system capacities are as follows:
■
Up to 108 simultaneous two-party conversations
IMPORTANT:
If more than 108 conversations are in progress at the same
time, blocking can occur.
■
Up to 80 line/trunk jacks, including loop-start, ground-start, DID,
and tie
■
Up to 255 extension endpoints that support a combination of the
following:
—
Up to 255 physical extension jacks for tip/ring telephones
and adjuncts
—
Up to 127 logical digital data ports (through ISDN terminal
adapters connected to jacks on the MLX module) providing
RS-232 connections to data terminals and personal
computers
■
System call-handling capability of 3888 hundred call seconds
per hour (ccs/hr)
■
Up to three 100D DS1 modules, maximum two per carrier
■
Up to five 800 NI-BRI modules, maximum three per carrier
(Release 4.0 and later)
■
One CTI link when operating in Hybrid/PBX mode
The system has a total capacity of 280 jacks (80 outside lines/
trunks plus 200 extensions); however, each MLX module extension
jack supports two logical endpoints (extension devices that can
operate simultaneously and independently of each other). For
example, an MLX telephone with a Multi-Function Module (MFM)
plugs into one extension jack, but the jack supports both the
telephone and the equipment (for example, a fax or an answering
machine) connected to the MFM.
Similarly, although the 100D module has only one jack, it can serve
up to 24 endpoints (emulated lines/trunks or PRI lines/trunks).
Thus, you can configure the system to connect up to 80 lines/trunks
and 255 extension endpoints-a total of 335 endpoints.
The following table, Table of Hardware and Software Capacities,
lists the hardware and software capacities of the system.
Constraining Factors appear with a checkmark (

explained at the end of the table.
