CONNECTING THE TELEPHONE
You must have a MODULAR phone, but you do not need a modular handset

MODULAR PHONE, including the Trimline model.

receive a program from a friend, the friend ill start in Originate
mode, and you ill start in Ans er mode.

the service you are using. There are some additional instructions in
