The Multipoint Switching and Conferencing Unit (MUSAC-A) combines a time switch unit
(MTSC) and a powerful signal processor on one chip. The MUSAC-A enhances the
capabilities of a PBX by supporting teleconferencing and multipoint data communication
over voiceband channels. Digital signal processing techniques are used to implement
the conferencing algorithms. Up to 64 channels of the 512 incoming PCM channels may
be manipulated by the signal processor and output to any of 256 outgoing PCM
channels. All functions are programmed and controlled via an 8-bit standard
μ
P interface
(Intel type).
The MUSAC-A is fabricated using the advanced CMOS technology from SIEMENS and
is mounted in a P-LCC-44 package. Inputs and outputs are TTL-compatible.
The PEB 2445 is pin and register compatible to the PEB 2045.
In addition, it includes the following features:
Conference Unit
Programmable attenuation for each output channel in the range of
4 dB up to 12 dB.
The attenuations of the outputs and the attenuations in the conference unit can be
selected independent of one another.
