CCIS Networking via IP (Non Peer-to-Peer Connections Basis).



The PZ-(X)IPLA daughter board is an optional interface package for converting the
Real Time Transfer Protocol (RTP) packets on the IP network to PCM highway. IP
telephones must be connected directly to the IP bus. When IP telephones are
required to be connected to conventional PCM based digital circuit, the PZ-(X)IPLA
converts IP packet signals. The PZ-(X)IPLA provides the digital signal processors
(DSPs) for IP stations and trunks.
A DSP provides format conversion from circuit switched networks (TDM) to packet
switched networks (IP). Each voice channel from the circuit switched network is
compressed and packetized for transmission over the packet network. In the reverse
direction, each packet is buffered for de-jittering, decompressed, and sent to the
circuit switched network. Each DSP converts a single speech channel from IP to TDM
and vice versa.
K-CCIS – IP with PVA
Enhancements
Version 3.01 or higher CPU software and K-CCIS – IP Compact Flash with
PVA License is required.
The K-CCIS – IP with PVA feature provides the benefits and additional feature
compatibility of Key-Common Channel Interoffice Signaling (K-CCIS) between
multiple systems including NEAX PBX systems connected together over a Data
Communication IP Network (Intranet). Voice Signals and common signaling from and
to distant offices are converted into IP packets and transmitted through the Data IP
Network. When using this feature, both Voice and Data Communication lines are
integrated into one network and communication costs can be reduced.
This feature is available betweenUNIVERGE SV8100, Electra Elite IPK II, Electra
Elite IPK and NEAX PBX systems.
The following features are provided:

IP trunk connections over CCIS Networking via IP provide telephony services
between the UNIVERGE SV8100, NEAX IPS, IPX, SV7000 and the UNIVERGE
SV8300.
The UNIVERGE SV8100 uses the NEC proprietary CCIS Peer to Peer protocol
over IP to communicate from system to system.
The PZ-(X)IPLA is required for connections between IP terminals and IP trunks.
Only one PZ-(X)IPLA daughter board can be accommodated per system with a
maximum of 128 DSP resources per system.
