NEC 2000 IPS manual Ccis Networking via IP Non Peer-to-Peer

Chapter 14 Common Channel Inter-Office Signaling (CCIS)

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 IVS2, NEAX 2400 IMX/IPX or Electra Elite IPK that does not support peer-to-peer 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	Maximum Voice Channels
	per IP Trunk
10 ms	4
20 ms	8
30 ms	16
40 ms	16

Maximum 127 voice channels can be provided per system (point-to-multipoint connection). IP trunk cards must be connected with the intranet via router.
