TransTel Model TD-824-I Digital Telephone System – Programming Forms Manual

Example 2:
A customer has local lines and a Foreign Exchange (FX) into a town just across the state line (and in another area
code). He wants to make sure calls to the other town always go over the FX.
The telephone numbers for the next town use 5 different central office codes, 541 through 545. The area code for
the next town is 838. Most of his office staff is used to dialing the next town from home and they pick up the phone
and dial 1-838-541-1234 (for example).
The TD-824i is programmed to take this digit string and make sure it gets on the FX line, which is in trunk group 2.
Modify digits table 06 is to be used as a reference in this example.
To allow the call to go out over the FX, we will need to remove the 1 plus the area code, so the digits to delete field
will be programmed to remove 4 digits (1838). That leaves 541-1234 remaining. This digit string is what is required
to dial on the FX, so we do not add any digits to it.

Example 3:
The system is installed in a branch office in the suburbs. The main headquarters downtown has provided an OPX
circuit that acts as a station off the headquarters’ telephone system. To reach anyone at headquarters, all someone
in the suburbs office has to do is access the OPX (which appears as a CO trunk on the TD-824i) and dial an
extension number. However a number of employees still access a CO line and dial the company’s main number
downtown. This ties up a CO line in the suburban office and another one at main headquarters. The company
wants any calls made to the main HQ office to instead go over the OPX circuit to HQ. The number is a local call.
The telephone number is 638-8923.
To make this work, we will tell the system in Form 75-01 to recognize 638-8923 and to use route table 11.

On Form 76-11, we will tell the system to use trunk group 3 and modify digits plan 2.

Note: Display will not show all this information onscreen at one time. As you enter information, display will scroll off
to the left, showing further entries on the right.
On Form 77-03, we will program the system to delete all 7 of the digits dialed (638-8923) and replace it with 0
(zero) to ring the operators’ station.

Example 3A:
After the system has been in a while, the customer wants to be able to call HQ using the local lines if the OPX is
busy.
We will add to Form 76-01. On it we will make trunk group 1 the second choice. Since the digits need no
modification from the 7 that are dialed into the TD-824i, we do not need to assign a modify digits table.
