Telephony media modules

The G350 supports the MM711, MM714, and MM716 analog media modules, the MM312,

MM712, and MM717 DCP media modules, the MM710 E1/T1 media module, and the MM720 and MM722 BRI media modules.

MM711 analog media module

The MM711 provides analog trunk and telephone features and functionality.

Configuring MM711 ports

The administrator can configure any of the eight ports of the MM711 as follows:

●

●

●

Central office trunk, either loop start or ground start

Analog Direct Inward Dialing (DID) trunks, either wink-start or immediate-start

2-wire analog Outgoing CAMA E911 trunks for connectivity to the PSTN

Issue 5 June 2008 25

Optional components

●

●

MF signaling is supported for CAMA ports

Analog, tip/ring devices, such as single-line telephones with or without LED message waiting indication

MM711 also supports

●

Three ringer loads (ringer equivalency number) for up to 2,000 feet (610 meters) for all eight ports

●

Up to eight simultaneously-ringing ports

Note:

●

Note:

The media gateway achieves this number of ports by staggering the ringing and pauses between two sets of up to four ports.

Type 1 Caller ID

●

Ring voltage generation for a variety of international frequencies and cadences

Figure 8: The MM711 media module

MM714 analog media module

The MM714 analog media module provides four analog telephone ports and four analog trunk ports.

Note:

Note:

The four analog trunk ports

cannot

be used for analog DID trunks. Instead, the four analog telephone ports must be used.

Configuring MM714 ports

The MM714 provides you with the capability to configure any of the four trunk ports as:

●

●

A loop start or a ground start central office trunk with a loop current of 18 to 120 mA

A two-wire analog Outgoing CAMA E911 trunk, for connectivity to the PSTN. MF signaling is supported for CAMA ports.

Configuring MM714 line ports

The MM714 provides you with the capability to configure any of the four telephone ports as:

●

A wink-start or an immediate-start DID trunk

●

Analog tip/ring devices such as single-line telephones with or without LED message waiting indication

MM714 also supports

●

●

Three ringer loads, which is the ringer equivalency number for up to 2,000 feet (610 meters) for all eight ports

Up to four simultaneously-ringing ports

●

●

Type 1 caller ID and Type 2 caller ID

Ring voltage generation for a variety of international frequencies and cadences

Figure 9: The MM714 media module

MM716 analog media module

The MM716 provides 24 analog ports supporting telephones, modem, and fax. These ports can also be configured as DID trunks with either wink-start or immediate-start. The 24 ports are provided via a 25 pair RJ21X amphenol connector, which can be connected by an amphenol cable to a breakout box or punch-down block.

Configuring MM716 ports

The MM716 provides you with the capability to configure any of the 24 ports as:

●

●

Analog tip/ring devices such as single-line telephones with or without LED message waiting indication

A wink-start or an immediate-start DID trunk

MM716 also supports

●

Three ringer loads, which is the ringer equivalency number for up to 2,000 feet (610 meters) for all 24 ports

Up to 24 simultaneously-ringing ports

●

●

●

Type 1 caller ID

Ring voltage generation for a variety of international frequencies and cadences

The MM716 is compatible with Avaya Communication Manager release 3.1 and higher, and branch gateway firmware version 25.0.0 and higher.

MM312 DCP media module

The MM312 DCP media module provides 24 Digital Communications Protocol (DCP) ports with

RJ-45 jacks. The MM312 supports simultaneous operation of all 24 ports. Each port can be

connected to a two-wire DCP telephone. See Appendix B: Supported Avaya telephones

for a list of compatible DCP telephones.

Note:

The MM312 does not support four-wire DCP telephones.

Note:

Figure 11: The MM312 media module

MM712 DCP media module

The MM712 DCP media module provides eight DCP telephone ports. The ports support

two-wire Digital Communications Protocol (DCP) telephones. See Appendix B: Supported

Avaya telephones for a list of compatible DCP telephones.

Figure 12: The MM712 media module

MM717 DCP media module

The MM717 DCP media module provides 24 DCP ports of two-wire DCP functionality exposed as a single 25-pair amphenol connector. The DCP ports are exposed by connecting the module via a standard amphenol cable to a punch-down block with RJ-11 jacks. The MM717 allows you to use one of the smaller media module slots for a large number of DCP telephones.

MM710 E1/T1 media module

The MM710 E1/T1 media module terminates an E1 or T1 trunk. The MM710 has a built-in

Channel Service Unit (CSU) so an external CSU is not necessary. The CSU is only used for the

T1 circuit.

The MM710 features:

●

●

●

ISDN PRI capability (23B+D or 30B+D)

Trunk signaling to support US and International CO or tie trunks

Echo cancellation in either direction

Figure 14: The MM710 media module

MM720 BRI media module

The MM720 BRI media module provides eight ports with RJ-45 jacks that can be administered either as BRI trunk connections or BRI endpoint (telephone and data module) connections.

Note:

●

Note:

The MM720 BRI media module cannot be administered to support both BRI trunks and BRI endpoints at the same time. However, the MM720 BRI Media

Module supports combining both B-channels together to form a 128-kbps channel. CM 3.1 enables combining B-channels, using BONDing, to form a higher bandwidth connection.

Finally, if the MM720 BRI Media Module is administered to support BRI endpoints, it cannot be used as a clock synchronization source.

For BRI trunking, the MM720 BRI media module supports up to eight BRI interfaces to the central office at the ISDN TE reference point. Information is communicated in two ways:

●

Over two 64-kbps channels, called B1 and B2, that can be circuit-switched simultaneously

Over a 16-kbps channel, called the D-channel, that is used for signaling. The MM720 occupies one time slot for all eight D channels.

Issue 5 June 2008 29

Optional components

The circuit-switched connections have an A- or Mu-law option for voice operation. The circuit-switched connections operate as 64-kbps clear channels when in the data mode.

For BRI endpoints, the MM720 BRI media module supports up to 16 BRI stations and data modules that conform to AT&T BRI, World Class BRI, and National ISDN NI1/NI2 BRI standards.

The MM720 BRI media module provides -40 volt phantom power to the BRI endpoints.

Figure 15: The MM720 media module

MM722 BRI media module

The MM722 BRI media module provides two 4 wire S/T ISDN BRI 2B+D access ports with

RJ-45 jacks. Each port interfaces to the central office at the ISDN T reference point. Information

is communicated in the same manner as for the MM720. See MM720 BRI media module on page 29.

Note:

Note:

The MM722 media module does not support BRI stations or combining both B channels together to form a 128-kbps channel.
