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.
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.
You can install this card in slots 1 through 4 in the Media Gateway. The card is not supported
in the Media Gateway Expansion.
Note:
When configuring BRI trunks, the MISP (NTBK22) card must be co-located in the same
Media Gateway as the SILC (NT6D70) and UILC (NT6D71) cards the MISP is supporting.
Refer to ISDN Basic Rate Interface: Installation and Configuration (NN43001-318) and ISDN
Basic Rate Interface: Features (NN43001-580) for additional information.
