TIE Line Network – Alternate Routing
Description
When more than two PBXs at different locations are interconnected with a network of TIE
Lines, your KX-TD500 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-TD500 bypasses it and
selects the secondary-route. On reception of a TIE call, KX-TD500 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.

1.
Ext.1000 dials "77+952+2000."
2.
When "952" is found in the table, TG10 (Hunt Sequence 01 for "952") is selected
automatically.
•
If TG10 is not available, TG11 (Hunt Sequence 02) will be selected. In this case, the call
is sent to PBX-2 via PBX-3 and -4. The treatment of the call is decided by Routing Table
of PBX-3 and then PBX-4.
3.
The call is sent to PBX-2.
