Mm710 Ds1 Media Module - Avaya G350 Maintenance Manual

Avaya Communication Manager controlled maintenance
MG-DS1 (DS1 Interface Media Module)
Echo cancellation is turned on or off on a trunk group basis using the change trunk-group command.
If the TRUNK GROUP field, DS1 Echo Cancellation? is set to y, echo cancellation will be
applied to every MM710 trunk member in that trunk group. The echo cancellation parameters used for a
given trunk member are determined by the Echo Cancellation Configuration Number administered on the
DS1 Media Module form for that specific trunk's board.
NOTE:
It is not necessary to busyout a port or trunk group to change the DS1 Echo
Cancellation? field on page 2 of the change trunk-group form; however, the
modified setting will not take effect until one of the following occurs:
Echo cancellation on the MM710 is selectable per channel, even though it is administrable on a trunk
group basis. For example, if all but two ports on a MM710 need to have echo cancellation applied, those
two ports must be put in a trunk group where the DS1 Echo Cancellation field is set to n. The
remaining ports will be in a trunk group(s) where the DS1 Echo Cancellation field is set to y. A
user will have the ability to cancel echo coming from the network (far-end echo) or coming from the
switch (near-end echo).

MM710 DS1 Media Module

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 MG-DS1 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.
NOTE:
The MM710 provides Echo Cancellation, and in addition, the MM710 firmware may be
updated using the firmware download feature.
The MG-DS1 maintenance strategy includes logging in-line errors reported by the MG-DS1 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 MG-
DS1 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.
