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.
