DEFINITY Switch Connectivity

1 Networking Overview

PACCON (si only)

The Packet Controller (PACCON) board (TN778) is replaced by the NetPkt board (TN794) starting in R7. For pre-R7 systems, PACCON provides an interface to the processor for D-Channel signaling over the packet bus.

The following table gives a summary of the different types of call connections and how the voice and signaling data are transmitted between switches.

For DCS+, X.25, and ppp connection types, the signaling and voice data are sent together over tie-trunk facilities as TDM-multiplexed frames. The DCS signaling data is sent as packets over a permanent virtual circuit (PVC) on tie-trunk facilities.

For C-LAN Ethernet connections, the signaling and voice data are sent together over tie-trunk facilities as TDM-multiplexed frames. The DCS signaling data is sent as TCP datagrams over an IP network through the C-LAN.
