MM714 provides 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 public switched telephone network (PSTN). MF signaling is supported for CAMA ports.

MM714 provides the capability to configure any of the four line ports as:

• A wink-start or an immediate-start Analog Direct Inward Dialing (DID) trunk

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

The MM714 Analog Media Module also supports:

• Three ringer loads, which is the ringer equivalency number, for all four line ports, for the following loop lengths:

  • 20,000 feet (6096 meters) over 0.65 mm (.025 in.) wire (22 AWG)

  • 16,000 feet (4877 meters) over 0.5 mm (.02 in.) wire (24 AWG)

  • 10,000 feet (3048 meters) over 0.4 mm (.016 in.) wire (26 AWG)

    At .1 or less REN ringer loads, the supported loop length is 20,000 feet (6096 meters) at 22, 24, and 26 AWG.

• Up to four ports ringing simultaneously

• Type 1 caller ID and Type 2 caller ID

• Ring voltage generation for a variety of international frequencies and cadences

A hard-wired ground wire is added for each IROB-to-earth ground.
