Conditions/Comments
The collision alarm will continue until the IP address conflict is resolved.
The collision detection will only occur in the same network subnet as the SV9100.
The G-ARP packets are sent every 5 minutes, this timer is not programmable.
If multiple IP address collisions are detected only one will be shown on the Alarm Display
Telephone. The table below shows information about alarm priorities.

IPLE Blade

GPZ-IPLE Blade
When assigning the IP addresses to the GPZ-IPLE and GPZ-IPLE Gateway, the addresses must be in the
same network address range (subnet). The GCD-CP10 Ethernet connection requires a separate IP
address in a different network address range (subnet).
When you have a GPZ-IPLE card attached to the GCD-CP10, the GCD-CP10 NIC is no longer required to
be connected to the network. All applications that previously terminated to the GCD-CP10 NIC card can
now be terminated through the GPZ-IPLE NIC.
For example, PC Pro, Web Pro, SMDR, etc. terminate to the GPZ-IPLE NIC card, when installed. Both the
GPZ-IPLE and GCD-CP10 NIC share the same default gateway assignment. The default gateway
command is used by both NICs, allowing only one device, GPZ-IPLE or GCD-CP10, to route outside of its
own network address range (subnet).
The programming information can be found in the relevant section of the IP Manual.
When an IP Phone or IP Trunk calls a legacy device (Keyphone, SLT, trunk) the speech has to be converted
from IP to TDM technologies. The GPZ-IPLE card provides this function. The GPZ-IPLE card has a
maximum capacity of 256 DSP resources on board; each one can convert a speech channel from IP to
TDM and vice versa.
Note: It is possible for IP phones to talk directly to other IP phones without using any DSP's on the GPZ-
IPLE card. This method is referred to as Peer to Peer communication.
Available Codec's
A codec is a standard for converting an analogue signal to digital. This conversion process is handled by
the DSP (Digital Signal Processors) on the GPZ-IPLE card.
Each codec has different voice quality and compression properties. The correct choice of CODEC will be
based on the amount of bandwidth available, the amount of calls required and the voice quality required.
