Avaya 03-300430 User Manual

The MM710 Universal DS1 Interface Media Module provide an interface to the DS1 facility, and 
are designed to support 24 DS0 channels on a 1.544 Mbps DS1 link, or 32 DS0 channels on a 
2.048 Mbps link. The DS0 channels can be administered as trunks to other switches, lines to 
off-premises stations, ports to line-side PRI terminating devices, or ports to other line-side 
non-PRI terminating devices. (DS0 channels on the MM710 can only be administered as trunks 
to other switches.) For more information on how MM710 ports can be used, see these 
maintenance objects: ISDN-SGR, ISDN-TRK, ISDN-LNK, TIE-DS1, CO-DS1, DID-DS1, and 
WAE-PT. 

Note:

The MM710 provides Echo Cancellation, and in addition, the MM710 firmware 
can be updated using the firmware download feature.

The MG-DS1 maintenance strategy includes logging in-line errors reported by the MM710 
Media Module, running tests for error diagnosis and recovery, and raising or clearing 
maintenance alarms.
MM710 Media Modules support the following:

●

Digital Tie, CO, and DID trunks

●

DS1 off-premises (OPS) lines

●

Narrowband and wideband access endpoint ports

●

ISDN-PRI trunks and accompanying signaling channel

●

PRI endpoint ports (PE-BCHL) and accompanying signaling channel

Each trunk, line, or endpoint has its own maintenance strategy, but all depend on the health of 
the MM710 Interface Media Module. Refer to the following MOs for details: TIE-DS1, CO-DS1, 
DID-DS1, OPS-LINE, ISDN-TRK, ISDN-LNK, ISDN-SGR, WAE-PT and PE-BCHL.
