NORTEL NT5B18ABAA LS/DS ID 8PORT CO CARD

The BCM-CTM 8 connects up to eight analog CLID PSTN lines to the BCM system. Two auxiliary ports permit the connection of a 33.6+ Kbps modem, fax machine or single line analog telephone to line 1 or 5. When the auxiliary device is using line 1 or 5, the BCM system does not allow other telephones to use line 1 or 5. When a single line analog telephone is connected to the auxiliary port, it can be used as an emergency telephone.
