Avaya M770 Frame Switch Domains

The Avaya M770 supports two Frame Switches, named DomainXs: DomainXL (Left DomainX) spans slots 1-7, and DomainXR (Right DomainX) spans slots 8-14. Each DomainX supports up to 6 Gbytes of bandwidth. You can insert the M32-100T into either DomainX, provided you don't exceed the maximum of 100 Domain Resource Units (DRUs) per DomainX. Each module uses a certain number of DRUs; the M32-100T uses 12 DRUs.

M-ACC Module Architecture

The M-ACC module consists of separate X-Switch and ATM entities. The X-switch CPU connects the M-ACC module to the Avaya M770 X-Domain. The ATM CPU performs all ATM signalling. Each entity has it’s own embedded software.
