Hardware and Software Capacities
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
NOTE:
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, tie, and DSI
— Up to 400 extension endpoints that support a combination of
the following:
— Up to 272 physical extension jacks for telephones and
adjuncts
— Up to 200 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 3828 hundred call seconds
per hour (ccs/hr)
— Up to three 100D DS1 modules, maximum two per carrier;
the 24 channels on each 100D DSI module count toward the
80 line/trunk capacity
— Up to five 800 NI-BRI modules, maximum two per carrier
(Release 4.0 and later)
— One CTI link when operating in Hybrid/PBX mode
The system has a total capacity of 352 physical jacks (80 outside
lines/trunks plus 272 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 analog
modem) 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
400 extension endpoints—a total of 480 endpoints.
The next table, Hardware and Software Capacities, lists the
hardware and software capacities of the system. Constraining
