KDB-SLI

This is a daughterboard that can be installed only in the 12 or 24 button keyset. The KDB-SLI will provide one additional SLI circuit for the connecion of any statndard telephone device. This KBD-SLI will only operate when the keyset is connected to a DLI card installed in the first cabinet so it can use the second B channel. NOTE: The circuitry on a KDB-SLI does not provide a disconnect signal or have the over voltage protection necessary for OPX operation.
