Introduction
The NTBK22 Multi-Purpose ISDN Signaling Processor (MISP) card is a
microprocessor-controlled signaling processor that performs Data Link
(Layer 2) and Network (Layer 3) processing associated with ISDN BRI and
the OSI protocol.
The NTBK22 Multi-Purpose ISDN Signaling Processor (MISP) card is
specific to Option 11C system and is supported on the Main cabinet. It
performs Data Link (Layer 2) and Network (Layer3) processing associated
with ISDN BRI and the OSI protocol. A description of the ISDN BRI feature
is contained in ISDN Basic Rate Interface: Maintenance (NN43001-718).

Physical description
The MISP occupies one slot in the Media Gateway. It uses one of the
network loops to interface with SILCs and UILCs and to provide 32
timeslots for D-channel signaling and packet data transmission. The other
loop address is used to communicate with the Call Server.
