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 DS1-MM can only be administered as trunks to other switches.) For more information on how MM710 ports can be used, see the maintenance objects (MOs): ISDN-SGR, ISDN-TRK, ISDN-LNK, TIE-DS1, CO-DS1, DID-DS1, and WAE-PT.
| The MM710 provides Echo Cancellation, and in addition, the MM710 firmware may be updated using the firmware download feature. |
The DS1-MM maintenance strategy includes logging in-line errors reported by the DS1-MM Media Module, running tests for error diagnosis and recovery, and raising or clearing maintenance alarms.
MM710 Media Modules support the following:
Each trunk, line, or endpoint has its own maintenance strategy, but all depend on the health of the DS1-MM 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.
