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
