TOA Electronics CP-63 manual Tie-line for 3 exchanges

3-6 The order of Tie-line link usage

The Tie-line Link Number which is used in calls between exchanges is not directly indicated, but you can possibly get it from the link number which is indicated on the HC-62.

When one Tie-line Link brings up some problems which cause the system not to work properly, try to find which link number is causing the problems from the indication on the HC-62 of the exchange making the call.

As Fig. 1 and Fig. 2 show, in the exchanges which make calls, the DL Link Number corresponds with Tl Tie-line Link Number.

In the exchange which is called, the Tie-line Link Number of the Tl Unit is fixed by connection between exchanges.

DL Links are used in numerical order.
