‡ The system is said to have a total capacity of 224 (80 CO trunks plus
144 extensions), However, those are physical jacks. Each MLX
station jack represents 2 logical endpoints (ports). For example, an
MLX telephone with a Multi-Function Module (MFM) plugs into only
1 station jack, but the jack supports the telephone and the adjunct
connected to the MFM (fax machine, answering machine, etc. ) The
1 station jack is supporting 2 endpoints.
Although it has only 1 jack, the 100D module can serve up to
24 endpoints. Therefore, the entire system can be configured to
Connect up 1080 trunks and 255 station endpoints, a total of
335 endpoints. This total of 335 endpoints exceeds the system’s
capacity of 216 time slots. If more than 216 endpoints are in use at the
same time, blocking can occur.
