Chapter 14 Common Channel Inter-Office Signaling (CCIS)

For DtermIP to DtermIP connection via CCIS (Peer to Peer connection), the voice data is transmitted and received directly between DtermIPs via Intranet (CCIS via IP). For Dterm IP to Legacy terminal connection via CCIS, the IP-PAD card is required to transmit and receive the voice data. This card is used to control and convert the voice to data. The control signals are managed by the MP card in either of the connection above.
