Nortel Meridian 16 Channel Analog Message Waiting Line Card (NT8D09BA)

The NT8D09 Analog Message Waiting Line Card is an Intelligent Peripheral Equipment (IPE) line card that can be installed in the NT8D37 IPE module. Up to 16 cards are supported. The analog message waiting line card provides talk battery and signaling for up to 16 regular 2-wire common battery analog (500/2500-type) telephones, modems, and key systems. This card can also provide a high-voltage, low-current signal on the Tip and Ring pair of each line to light the message waiting lamp on phones equipped with that feature. This voltage is provided by the NT6D40 Peripheral Equipment Power Supply, DC. Cards later than vintage NT8D09AK support u-Law and A-Law companding, and provide a 2 dB transmission profile change. The transmission change improves performance on long lines, particularly for lines used outside of a single-building environment. Compatible with Meridian 1 systems.
