CCIS Networking via IP (Non Peer-to-Peer)
When the distant NEAX 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
ƒ IP trunk connections over CCIS Networking via IP are available when the distant systems are
NEAX 2000 IVS 2 , NEAX 2400 IPX or Electra Elite IPK that do not support peer-to-peer
connections.
ƒ The IP-PAD is required for connections between IP Enabled D term terminals and IP trunks.
ƒ Maximum one IP trunk card can be accommodated per PIM. Maximum eight IP trunk cards can
be accommodated in the system
ƒ Maximum voice channels per IP trunk card depends on the payload period as follows (payload
period can be assigned in system programming):
Payload Period
Maximum Voice Channels
per IP Trunk
10 ms 4
20 ms 8
30 ms 16
40 ms 16
ƒ Maximum 127 voice channels can be provided per system (point-to-multipoint connection).
ƒ IP trunk cards must be connected with the intranet via router.
