Knowledge Worker Environment - Nortel CCT User Manual

Knowledge worker environment

In a knowledge worker environment, Communication Control Toolkit requires
the following network Ethernet ports:
one 10/100BASE-T port for the ELAN subnet
one 100BASE-T port (or better) for the Nortel server subnet
Network interface card binding order
Configure the binding order of the network interface cards so that the Nortel
server subnet card comes first, then the ELAN subnet card, and then the virtual
adapters for remote access. Disable NetBios on the network interface card
connected to the voice switch (ELAN subnet NIC); because NetBios is not a
routable protocol, NetBios traffic does not work well on multi-homed hosts.
Nortel server subnet requirements
The Nortel server subnet is an Ethernet link between Communication Control
Toolkit and the client PCs.
To ensure that Communication Control Toolkit traffic is not affected by non-
Communication Control Toolkit data traffic, create a dedicated (quiet) subnet for
Nortel voice application servers, and connect Communication Control Toolkit to
this subnet. Use an Ethernet switch or router to provide routing between this
subnet and your Nortel server subnet.
The illustration on page 92 shows this network configuration.
