The MM711 media module provides analog trunk and phone features and functionality.

The administrator can configure MM711 ports 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 PSTN

• MF signaling for CAMA ports

• Analog, tip/ring devices, such as single-line phones, with or without a LED message waiting indicator

Other MM711 media module hardware features include the following:

• Three ringer loads, which is the Ringer Equivalency Number (REN), for the following loop lengths:

  • 20,000 feet (6096 meters) with a 0.65 mm wire

  • 16,000 feet (4877 meters) with a 0.5 mm wire

  • 10,000 feet (3048 meters) with a 0.4 mm wire

  With ringer load of .1 or less, the supported loop length is 20,000 feet (6096 meters) with a 0.65 mm, 0.5 mm, and 0.4 mm wire.

• Up to eight simultaneously ringing ports

  Branch Gateway supports this number of ports by staggering ringing and pauses between two sets of up to four ports.
