The Mm710 Ds1 Media Module; Media Module Administration And Options - Avaya G700 Maintenance Manual

6 Avaya MultiVantage Software-Controlled Maintenance:
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).

The 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 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 .
Note: 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:
• 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
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.

Media Module Administration and Options

The DS1 configuration for each Media Module is administered on the DS1 Media Module form.
Bit Rate is set to 1.544 Mbps for 24-channel systems, and 2.048 Mbps for 32-channel systems.
Country Protocol is used to drive layer 3 protocol decisions based on PRI specifications
specific to a given country (not those related to specific features). This Country Protocol is
independent of the Country parameter administered on the country-options system-
parameters form. Different DS1-MM Media Modules may be administered with different Country
