IP-Connected Trunks
IP-connected trunks allow trunk groups to be defined as ISDN-PRI-equivalent tie
lines between switches over an IP network.
lines between switches over an IP network.
Trunks using IP connectivity provide cost-reduction and simplified management.
Benefits include a reduction in long distance voice and fax expenses, facilitation of
global communications, full-function networks with data and voice convergence, and
network optimization by using the existing network resources.

H.323 Trunk
The TN802B IP Interface in Medpro mode enables H.323 trunk service using IP
connectivity between two DEFINITY ECS systems. H.323 trunk groups can be
configured as DEFINITY-specific tie trunks supporting ISDN trunk features such as
DCS+ and QSIG, or as generic tie trunks permitting interconnection with other
vendors’ H.323 v2-compliant switches, or as direct-inward-dial (DID) type of
“public” trunk providing access to the switch for unregistered users. A variety of
signaling options can be chosen by the system administrator.

IP Trunk
The IP Trunk mode (of the TN802B IP Interface) will typically be chosen for
interoperability with existing TN802 (as opposed to the TN802B) IP Interface circuit
packs. IP Trunk mode can be used only between two DEFINITY switches. Each IP
Interface circuit pack in IP Trunk mode provides a basic twelve-port package that can
be expanded up to a total of 30 ports.

IP Softphones
DEFINITY IP Softphones operate on a PC equipped with Microsoft Windows
95/98/NT and with TCP/IP connectivity to DEFINITY ECS. DEFINITY IP Solutions
supports three IP Softphone configurations:
95/98/NT and with TCP/IP connectivity to DEFINITY ECS. DEFINITY IP Solutions
supports three IP Softphone configurations:
•
Road-warrior application of IP Softphone — a PC running the DEFINITY IP
Softphone application and an H.323v2-compliant audio application, with a single
IP connection to a DEFINITY server.

standard telephone with a separate PSTN connection to the DEFINITY server.

The DEFINITY IP Softphone can also operate in a “native H.323” mode, which is a
PC-based single phone with limited features.

Documentation on how to set up and use the IP Softphones is included on the
CD-ROM containing the IP Softphone software. The documentation includes a
Getting Started quick reference, an overview and troubleshooting document, and
context-sensitive help integrated with the softphone software.
