The PZ-( )IPLA contains a regular TCP/RTP/IP stack that can handle real time media. The

PZ-( )IPLA daughter board is an end-point on the IP network from the network administration
perspective.
The CD-CP00-US uses SIP Protocol to provide telephony services between remote stations

through the IP Network. This is an IETF/ITU standards-based protocol.
Speech-connection audio quality depends greatly on the available bandwidth between the stations

in the data network. Because Internet is an uncontrolled data network compared to an Intranet,
using this application in Intranet WAN environment with known (or controlled and assured) Quality
of Service (QoS) is highly recommended.
The PZ-32IPLA requires three IP addresses, the PZ-64IPLA requires five IP addresses and the

PZ-128IPLA requires nine IP addresses.
An on-board RJ-45 connector provides a WAN/LAN connection. Voice and signaling data to/from

the IP Stations are converted into IP Frames and transmitted through the Data Communication IP
Network.
PZ-32IPLA supports a maximum of 32 VoIP connections, PZ-64IPLA supports a maximum of 64

VoIP connections, PZ-128IPLA supports a maximum of 128 VoIP connections.
Duplex mode (Auto, Full, or Half) and speed (10 or 100 mbps) are configured via SV8100 chassis

programming.
In voice communication, particularly Internet telephony, the Mean Opinion Score (MOS) provides a
numerical measure of the quality of human speech at the circuit destination. The scheme uses
subjective tests (opinionated scores) that are mathematically averaged to obtain a quantitative indicator
of the system performance. The maximum MOS is 5.0.
UNIVERGE SV8100 supports a 100 rel option and Session Timer option.
