|SUBJECT:||New Telephone System #2|
Beginning Monday, May 1, 1972, a toll diverter will be installed on all Optigan telephone lines to insure proper dialing of outside numbers.
Whenever you are dialing an outside number, you must first dial the preliminary numbers indicated on the attached sheets. Check the attached sheets for the prefix you are going to dial and you will be able to locate the preliminary numbers in the box to the right of the prefix.
Example: If you wish to dial an outside number which begins with the prefix “221”, you must dial “91”, as indicated on the attached sheet, to secure the proper outside line.
If, when checking for the proper preliminary numbers, you find either “9”, “5”, “74”, or any combination of these numbers, you must preceed the entire set of numbers with “81”. (See the notation in the upper right hand corner of the attached sheets.)
Example: If you wish to dial an outside number which begins with the prefix “270”, you must first dial “81”, then dial “5”, and then dial the number you wish to reach.
Example: If you wish to dial an outside number which begins with the prefix “330”, you will find that the preliminary number in the box to the right of “330” is the combination “74 + 9”. This means that you mustfirst dial “81”, then dial “74”, followed by “9”, and finally the number you are trying to reach.
The institution of this system will lessen Optigan’s telephone costs substantially. Please try to follow the above procedure carefully. If a number is dialed improperly, you will reach a loud siren and your call will not go through.
If you have any questions, please consult Steve Dion, extension 67.
