Program Notes for Centrex
BN : AXS-003 revision 2 July 19, 1995
To use the AXS in conjunction with either Centrex or on the telephone set side of a PBX you must instruct it that it is working into the system (CODE 0650X) and what the C.O. access codes are (CODE 065XYY).
1. Centrex / PBX Compatibility CODE 0650X X = Extension Number Length
This program code instructs the AXS that it is working into CENTREX or PBX and the length of the extension numbers in the system. Therefore, the proper programming for two (2) digit extension numbers would be 06502. An entry of 06500 disables the CENTREX / PBX Compatibility.
2.Centrex Access Code CODE 065XYY X= Code Number (1-5)
YY=Access Code (1 or 2 digits)
This program code allows you to program up to 5 two digit access codes into the AXS dialer. If you required 3 different access codes because of different line groups you are accessing you would require 3 entries at this code. For example, if you are required to dial '9' for one C.O. group, '81' for a second group and '85' for a third group you would require the following program;
06519
065281
065385
0654
0655
It is imperative that unused code numbers are set to zero (0) length as above.
When a user is dialing be sure that they are dialing a Centrex access code before the number they are calling. In the Parallel Program before the instruction to Dial Drop Recorded Telephone Number to Trunk (instruction 60XX) insert instruction 63 Dial Drop Recorded Centrex Access Code followed by a Short Delay (5910). The 63 instruction dials the PBX access code that was dialed by the User, that was recorded by the dialer.
63 5910 6000 93 95 99
The AXS also comes preprogrammed with a parallel program to handle all calls that are not Centrex or PBX outgoing calls. Program 23 in the dialer is the default program which is loaded when the dialer's initial power up reset is done.The default program is as follows;
6000, 93, 99
To accommodate the systems that have the varying digit length, Software 088 or later allows the 60XX instruction to be 6000. When this instruction is contained in the string, as with the other program strings, an interdigit timer must expire or the Force Continue Digit be dialed to indicate the end of dialing before the AXS will continue to the next instruction. If the system being used only has one digit length for their internal numbers, then, as before, you should enter the same value in the 60XX instruction of program 23 as the number entered in the PBX Compatibility Box. The valid entries for extension digit length are 1 to 6.You must change the 6000 instruction to be 600x where x is the same extension number length as was programmed at CODE 0650x.
When a User goes off hook, to make a call, the AXS monitors the line to see if one of the programmed access codes is dialed. If a code is dialed the AXS stores that code in a buffer and returns dial tone to the user. It then proceeds to record the dial digits and search the tables for a match. Once a match is found and a parallel program is to run the access code must be dialed for an outside line. The 63 instruction does this. If one of the access codes is not dialed the dialer assumes that an internal call is required and defaults to program 23.
