The PZ-( )ILPA contains a regular TCP/RTP/IP stack that can handle real time media. The
PZ-( )ILPA ETU is an end-point on the IP network from the network administration perspective.
The CD-CP00-AU 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 Voice over IP connections, PZ-64IPLA supports a maximum
of 64 Voice over IP connections, PZ-128IPLA supports a maximum of 128 Voice over IP
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.
UNIVERGE SV8100 supports Early Media.
UNIVERGE SV8100 SIP restricts an outgoing call under the following conditions:
SIP configuration failed
SIP registration failed
CD-CP00-AU and MG16 Link down
Lack of PZ-( )ILPA resource
Lack of a PZ-( )ILPA bandwidth
Both port numbers can be configured by system data.
ToS Support.
