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.
