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 Factors appear with a checkmark (✓) and are explained at the end of the table.
