Host Communication Module

Overview

The host, as the client in the client/server model, maintains the connection to a Matrix Controller, SS7, ISDN, VDAC-ONE, or IP Network Interface Series 2 card. The host application can issue any number of requests to connect and disconnect. The CSP services each connection request instantaneously. Each subsequent connect request issued "steals" the previous connection.

API Messages

All API messages should be sent directly to the active matrix card’s IP address. Messages should not be sent to the matrix card’s shared IP address; the shared IP address is used for SIP redundancy only.
