ALCULATION
Voice over IP (NECi SIP, SIP stations, SIP trunks) requires DSP resources to be able
to convert from TDM
3
to IP technologies. DSPs (Digital Signal Processors) take a
TDM signal and convert to Realtime Transport Protocol (RTP) for transmission as
VoIP, and vice versa. Each IP to TDM conversion requires a DSP resource.
DSP resources are provided by the GPZ-IPLE It can be difficult to work out how
many DSP resources are required in an UNIVERGE SV9100 system, because:
not all IP Extensions/trunks are used at the same time
peer-to-peer calls do not use a DSP resource
GPZ-IPLE IP Addressing
The GPZ-IPLE requires two IP Addresses, one for Signaling (PRG 10-12-09), and
one for the DSP Resources (PRG 84-26-01).
When assigning the IP addresses to the GPZ-IPLE card, they must be in the same network
(subnet). If the CPU will be connected to the network it requires a separate IP address in a
different network (subnet). When an GPZ-IPLE card is attached to the CPU, using the CPU
NIC is no longer required. All connections that previously terminated to the CPU NIC card
can now be terminated to the GPZ-IPLE NIC. For example, PC PRO, Web Pro, and ACD all
terminate to the GPZ-IPLE NIC card when installed. Both the GPZ-IPLE and CPU NIC
share the same gateway assignment. The default gateway command in Program 10-12-03 is
used by both NICs, allowing only one device,
GPZ-IPLE or CPU, to route outside of its own
network.
The following chart shows the minimum and maximum number of IP addresses used
with different GPZ-IPLE card configurations.

The number of DSP channels
depends on the VOIP license
loaded to GCD-CP10 up to 256.
