AT&T MERLIN LEGEND Release 3.1 System Manager's Manual page 375

System Capacities
The system has a total capacity of 335 jacks (80 outside lines/trunks plus 255
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, T1 digital, or PRI facilities). Thus, you can configure the
system to connect up to 80 lines/trunks and 255 extension endpoints, a total of
335 endpoints.
IMPORTANT:
The system has a time-slot capacity of 216. If more than 216 endpoints are in
use at the same time, blocking can occur.
Table C–1 lists the hardware and software capacities of the system. Some
constraining factors appear with a checkmark (

If you are planning to expand your system, contact your AT&T representative for
additional considerations.
