5.3.4 Connection to a PBX
If the telephone entry system is going to be connected to a PBX system, you may need to program
extension numbers in place of a seven-digit telephone number. To do this, enter the extension
number and fill the remaining spaces with the # key in the phone number programming step. For
example, if the PBX system uses four-digit extensions and you want to program extension 2217 as a
phone number, in step 3, section 3.2.2 press:
3. (beep).
If the PBX system requires you to dial 9 to obtain an outside line, and you want to program some
outside line phone numbers in the system, program the number 9 as one of the alternate area codes.
In step 3, section 3.2.3 press:
3. (beep).
Then program the outside phone number as a long distance number (3.2.4) using the area code
reference number used to program 9.
5.3.5 Areas with 10-digit Dialing
If the telephone entry system is installed in an area where the telephone company has instituted 10
digit dialing, simply program the required number of alternate area codes into the system without
preceding the area code with the number 1. If 310 was one of the area codes required, in step 3,
section 3.2.3 press:
3. (beep).
Then program the outside phone number as a long distance number (3.2.4) using the area code
reference number used to program 310. Program additional area codes and phone numbers as
described in sections 3.2.3 and 3.2.4.
