The G450 Branch Gateway is a 19-inch 3U rack-mountable device. The Branch Gateway contains VoIP resources, a layer 2 switch, modular interface connectivity for traditional trunk and station access, and performs the function of a gateway or gatekeeper. It also houses eight Media Module bays. The Branch Gateway is designed to offer options and scalability. You can mix and match Media Modules, as well as add additional Branch Gateways as they grow in size.

S8300E server

The Avaya S8300E server is an Intel™-based server complexe that carry:

• Administration and maintenance provisioning software

• Web server

• Linux OS

• H.248 Branch Gateway Signaling Protocol

• CCMS messages tunneled over H.248 Signaling Protocol

The S8300E server can act as the primary server of the Branch Gateway, or can serve as a local survivable processor for remote or branch customer locations.

MM710B T1/E1 Media Module

Comcodes (for Services Ordering Only): 700439250, 700466634

The MM710B T1/E1 media module offers the combined features of a DEFINITY DS1 circuit pack and includes the following:

• A built-in CSU

• AMI-BASIC

• Both A-law for E1 and μ -law for T1

• Line Coding: AMI, ZCS, B8ZS for T1 and HDB3 or AMI for E1

• Stratum 3 Clock compatibility

• Trunk signaling for supporting US and International CO trunks and tie trunks as currently in existence

The MM710B T1/E1 media module supports the universal DS1 conforming to 1.544 Mbps T1 standard and 2.048 Mbps E1 standard.

ISDN PRI is also supported for T1 or E1 revenue-associated option. MM710B is RoHS compliant.

DEF DS1 LOOPBACK JACK 700A

Provides the ability to remotely troubleshoot the MM 710 T1/E1 media module. It is required for any customer with a maintenance contract and highly recommended for any other customer.

Material Code: 700406101

Apparatus Code: None

Required for any customer with a maintenance contract and an MM710 or MM7110B T1/E1 media module. Highly recommended for other customers to avoid expensive technician visits.

MM711 Analog Media Module

Comcodes (for Services Ordering Only): 700394661, 700466626

The MM711 Analog media module supports eight analog interfaces allowing the connectivity of Loop Start, Ground Start, Analog DID trunks, and 2-wire analog Outgoing CAMA E911 trunks. The MM711 Analog media module also allows connectivity of analog, tip/ring devices such as single line telephones, modems or group 3 fax machines. Each port may be configured as a trunk interface or a station interface.

Also included is support for caller ID signaling, ring voltage generation for a variety of international frequencies and cadences, and administrable line termination styles. MM711 is RoHS compliant.

MM714B Analog Media Module

Comcodes (for Services Ordering Only): 700453889, 700466618

The MM714B Analog media module supports four analog stations and four CO trunks, as well as an Emergency Transfer Relay between a line port and a trunk port. Analog DID trunk connections are associated with the ports labeled Line and not Trunk. MM714B is RoHS compliant.

MM712 DCP Media Module

Comcode (for Services Ordering Only): 700394745

The MM712 DCP media module allows connectivity of up to eight 2-wire DCP voice terminals. MM712 does not support 4-wire DCP telephones.

Signal timing specifications for the MM712 support TDM Bus Timing in receive and transmit modes. The Branch Gateway supplies only +5 VDC and –48 VDC to the MM712 media module. Any other required voltages must be derived on the module.

The MM712 comes with loop range secondary protection. The MM712 is also self-protecting from an over current condition on a tip and ring interface. MM712 is RoHS compliant.

MM716 24 port Analog Media Module

Comcodes (for Services Ordering Only): 700394703, 700466642

MM717 24 port DCP Media Module

Comcode (for Services Ordering Only): 700394711, 700501048

The MM717 DCP Medial Module supports 24 DCP stations. The MM717 uses a 25-pair amphenol connector on the media module’s faceplate. The 24 DCP ports are intended for in-building use only. Phone lines connected to those ports are not to be routed out-of-building. Failure to comply with this restriction could cause harm to personnel or equipment. MM717 is RoHS compliant.

MM720 BRI Media Module

Comcode (for Services Ordering Only): 700394752

The MM720 BRI media module contains eight ports that you can administer as BRI trunk connections or BRI endpoint (telephone and data module) connections. 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 D channel occupies one time slot for all eight D channels

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

The MM720 BRI media module does not support combining both B channels together to form a 128 Kbps channel.

For BRI trunking, the MM720 BRI media module supports up to eight BRI interfaces, or up to 16 trunk ports, to the central office at the ISDN S/T reference point.

For BRI endpoints, each of the eight ports on the MM720 BRI media module can support one integrated voice/data endpoint or up to two BRI stations and data modules. Supported endpoints must conform to AT&T BRI, World Class BRI, or National ISDN NI1/NI2 BRI standards. The MM720 BRI media module provides -40 volt phantom power to the BRI endpoints.

MM720 is RoHS compliant.

The MM721 BRI media module contains eight ports that you can administer as BRI trunk connections or BRI endpoint (telephone and data module) connections. 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 D channel occupies one time slot for all eight D channels

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

The MM720 BRI media module does not support combining both B channels together to form a 128 Kbps channel.

For BRI trunking, the MM720 BRI media module supports up to eight BRI interfaces, or up to 16 trunk ports, to the central office at the ISDN S/T reference point.

For BRI endpoints, each of the eight ports on the MM720 BRI media module can support one integrated voice/data endpoint or up to two BRI stations and data modules. Supported endpoints must conform to AT&T BRI, World Class BRI, or National ISDN NI1/NI2 BRI standards. The MM720 BRI media module provides -40 volt phantom power to the BRI endpoints.

MM720 is RoHS compliant.

MM722 2-port BRI Media Module

Comcode (for Services Ordering Only): 700395239

The MM722 BRI media module provides two 4 wire S/T ISDN BRI 2B+D access ports with RJ-45 jacks. Each port interfaces with the central office at the ISDN T reference point.

Information is communicated in the same manner as the MM720.

MM722 is RoHS compliant.
