G. INTERNET PROTOCOL CARD (IPC) AND INTERNET PROTOCOL RESOURCE
CARDS (IPRC)
4.123 There are five different types of Internet Protocol (IP) cards available for use with the
Inter-Tel system:
•
New Enhanced IP Resource Cards: The Inter-Tel Axxess Internet Protocol Resource
Card (IPRC) "enhanced" daughter card offers new technology for echo cancellation on
all calls routed through the IPRC, as well as enhanced diagnostics for troubleshooting
echo problems. When the enhanced daughter card is installed and programmed, the new
technology on the daughter card replaces the echo cancellers on the IPRC, resulting in
improved echo cancellation. There are two types of enhanced daughter cards available:
—

For more information, refer to the IPRC Enhanced Daughter Card Installation Instruc-
tions (document part no. 835.3195) and the IPC/IPRC and IP Endpoint Firmware
Notice (document part no. 835.2720-9).
•
Version 9.0.0 Firmware IPRC: Supports both IP devices and private networking.
When version 8.1.x or later IPRC firmware is used with a v9.0 or later Axxess system,
the IPRC allows an Axxess system to share IP endpoint and IP networking capabilities
on the same IPRC. This functionality allows for a cost reduction where one IPRC pro-
vides sufficient resources for both the IP endpoints and IP networking. Each IPRC sup-
ports up to 32 IP devices (16 IP devices without an IPRC daughter card), MGCP trunks,
SIP trunks, multi-protocol devices, Model 8602 IP softphone, or IP networking ports.
The new IPRC configuration replaces both the Private-Networking IPRC and Devices
IPRC in previous releases. When upgraded to v9.0, the system prevents IPRCs running
with firmware older than version 8.1 to come online.
•
Version 8.1 Firmware IPRC: Supports up to 32 IP devices, MGCP trunks, multi-pro-
tocol devices, and IP networking ports (it does not support the IP SoftPhone). This card
is also required if using peer-to-peer (P2P) audio. This card uses a software license and
does not require a PAL. Unlike prior versions of IPRC firmware, the v8.1 IPRCs cannot
be placed behind firewalls (from the endpoint perspective) or Network Address Transla-
tion (NAT) boxes. The new firmware also does not provide a BOOTP server for IP
address assignment. The card requires a static IP address or the use of either a third-
party BOOTP sever or a DHCP server. Inter-Tel, however, strongly recommends that
you use a static IP address for the IPRC.
NOTE:
points only, such as the Model 8600, Model 8662, Model 8620, and Model 8690. It does
not regulate the number of endpoints that use IP only, such as the Model 8660 and IP
PhonePlus, or the number of MGCP gateways/endpoints.
•
Version 1.x Firmware Networking IPRC: Supports 16 private networking ports using
IP. This card requires a networking PAL. If desired, you can upgrade this card to a v8.1
firmware IPRC.
