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 MG 1000S. 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 MG 1000S. The card is not supported in the MG 1000S Expansion.

Note: When configuring BRI trunks, the MISP (NTBK22) card must be co-located in the same MG 1000S as the SILC (NT6D70) and UILC (NT6D71) cards the MISP is supporting.
