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.

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.

Table C–1 lists the hardware and software capacities of the system. Some constraining factors appear with a checkmark () and are explained at the end of the table.

If you are planning to expand your system, contact your Lucent Technologies representative for additional considerations.
