The Extension on PABX
Gibbs: Good morning, Mr. Allison. Could you tell me how the user at any extension on our new PABX will benefit from its greater number of facilities? Allison: Of course. First you must make a clear distinction between internal and external calls. For internal calls, pick up the handset, wait for the dial tone- which is almost instantaneous with this electronic system- then simply dial the four numbers of the extension. Gibbs: How do you obtain an outside number? Allison: You pick up the handset, wait for the internal dial- tone, then push button number 2, which will send you the dial- tone of the outside network. After that, you dial the outside number in the usual way, using the appropriate local, regional or international codes. Gibbs: In what way does the PABX make the switchboard operator’s work easier? Allison: Well, you’ve probably noticed that each extension has four digits. The preceding two digits, which make up the full six- figure number, are the same for every extension in the company, in this case, 55. So anyone outside can dial 55 followed by the four digits of the internal number, and the call is switched directly to the internal extension without disturbing the operator. Gibbs: I see. So the operator isn’t really necessary? Allison: Yes she is, because she can still be contacted directly- her own number is 552222- and, if the phone rings for more than 15 seconds at any extension without being answered, the call is switched automatically to the operator. Gibbs: How do you transfer your number to another extension if you leave your office for a long period? Allison: Pick up the handset, wait for the internal dial- tone, push button 8, and you’ll receive another lower- pitched dial- tone, after which you dial the number of the extension in the office you’re going to. You’ll then get a short dial- tone informing you that your “new” number has been recognized and stored in the PABX. Now, when you come back to your office, don’t forget to dial 8 followed by your own extension number, so that your own number is returned to your office. Do make sure you do that, or all your calls will continue to be transferred to the office where you were before! Well, let’s make sure you’ve understood all that, shall we? Gibbs: OK. Pick up the handset. Internal dial-tone. Dial 8. Short recognition dial-tone. Extension number of the other office. On returning to my own office, I dial 8 then my own number. Would you mind explaining how I can be called back automatically if my correspondent’s line is engaged when I phone? Allison: Right. Don’t forget this system only works if both you and your correspondent go through the same exchange. For internal calls, this is obviously the case with the PABX. You dial your correspondent and receive the engaged tone. Then, you simply press button 4 and hang up. When your correspondent hangs up, the phone will ring in your office, which, in turn, causes the phone in your correspondent’s office to ring! Simple, isn’t it? Gibbs: I suppose so! Could you also let me know what…
