The MUSAC is a memory time switch device for a PCM PBX system, offering a variety of additional
features like multipoint switching, conference calls, programmable noise suppression and
attenuation. The MUSAC works either in standard configuration for usual switching applications or
in the primary access configuration, where it realizes, together with the PEB 2035 (ACFA) and the

configurations the conference and multipoint switching capability can be used.
