3.4.1 Description
The PZ-32IPLA/PZ-64IPLA/PZ-128IPLA daughter boards are used
for converting the RTP (Real Time Transfer Protocol) packets via the
IP network and PCM highway. The daughter board is installed on the
CD-CP00. The IP telephones are connected directly to the IP bus.
When IP telephones need to be connected to a conventional PCM-
based digital circuit, this board converts the IP packet signal into a
PCM signal format and connects to the PCM time division switch.
The PZ-32IPLA/PZ-64IPLA/PZ-128IPLA daughter board is required
for IP telephones to communicate with non-VoIP UNIVERGE
SV8100 telephones, and place or receive outside calls.
The VoIP daughter board provides the voice (RTP/RTCP) processing
function. The call control function is mounted on the CPU. Only one
version of the VOIPDB (32, 64, or 128) can be installed on the CPU
at a time.
The VOIPDB daughter board provides:
32 (PZ-32IPLA) channels
64 (PZ-64IPLA) channels
128 (PZ-128IPLA) channels
