CCIS Networking via IP (Non Peer-to-Peer)
When the distant PBX system does not support peer-to-peer, the systems are connected with IP trunks
(including Voice Compression Trunks (VCT)), via Time Division Switch (TDSW). Voice signals of IP
terminals are transmitted via IP-PADs, while those of legacy terminals are directly connected to the IP
trunks. Call control signals between the systems are also transmitted over the IP trunks. Voice
compression of G.729a (8Kbps) and G.723.1 (5.3Kbps/6.3Kbps) can be provided by the IP trunks with
.
VCT cards
Service Conditions on Non Peer-to-Peer Connections
IP trunk connections over CCIS Networking via IP are available when the distant systems are
NEAX 2000 IVS
connections.
The IP-PAD is required for connections between IP Enabled Dterm terminals and IP trunks.
Maximum one IP trunk card can be accommodated per PIM. Maximum eight IP trunk cards can
be accommodated in the system
Maximum voice channels per IP trunk card depends on the payload period as follows (payload
period can be assigned in system programming):
Payload Period
10 ms
20 ms
30 ms
40 ms
Maximum 127 voice channels can be provided per system (point-to-multipoint connection).
IP trunk cards must be connected with the intranet via router.
