14.04 Alternate Routing
Description When more than two PBXs at different locations are interconnected with a
network of TIE Lines, your KX-T336 works as an intermediate switching office to
other PBXs in the network by relaying tie calls from one PBX to another.
A problem of telephone switching is that blocking sometimes occurs on the
network, and a call cannot be switched as required because all the lines on a
given route are occupied or unavailable.
By utilizing this relay function, several alternative routes can be set up
beforehand in addition to the primary-route. This permits TIE calls to be routed
from “A to B” or “A through C to B” and so on.
If the primary-route is poor because of equipment failure or congestion, KX-
T336 bypasses it and selects the secondary-route.
On receipt of a TIE call, KX-T336 analyzes it to determine the destination to
which the call must be sent or the route by which the calls will be sent, and then
transmit it.
Alternate Routing makes a TIE Line Network more flexible in adapting to peaks
of traffic and it provides a variety of different routing plans.
