5.9.3.1 Interfacing the ELIC
The PCM interface of the ELIC can easily be connected to the Multipoint Switching and
Conferencing circuit MUSAC (PEB 2245) when using the set-up and PCM timing as
shown in figure 120. This configuration can then for example be used in a PBX to
implement conferencing functions for up to 21 simultaneous conferences.
