tion and termination networks directly, rather than having it run out of the origination network,
through the Call Relay 60 and back out to the destination network.
In this mode, the Call Relay 60 can support up to a maximum of 90 simultaneous calls when used as
an H.323 signaling gateway (this mode of operation is known as the “Gatekeeper Routed Call
Mode”); endpoints can register to the Call Relay 60’s gatekeeper.

Provides Load Balancing
Using multiple Call Relay 60 units provides a way for load balancing. For example, one unit can be
used as a primary portal and another as a secondary portal. You can divide the calls between portals
or simply use one as a backup. In the event of an IP link failure, the redundancy offers maximum
reliability.
SNMP Support
The Call Relay 60 supports Simple Network Management Protocol (SNMP), the standard protocol
used to exchange network information between different types of networks. The Call Relay 60 acts
as an SNMP agent to receive commands and issue responses to the network manager. The network
manager will then be able to perform certain functions, such as generating and sending traps.
Call Relay 60 communication
The Call Relay 60 provides a single IP address for accessing the public IP network.
Easy Connect to Console
Plugging a DB-9 cable provided by Quintum between a PC and the unit’s asynchronous RS-232 port
will connect the unit and get you up and running. Through this port, you are able to configure an IP
address for the Call Relay 60 portal.
