In a recent building demolition I grabbed an Amtel Apartment entry type phone. (I can email pictures). Basically there is no display on the unit...just a handset, hookswitch, red indicator "in use" light, and a touchtone keypad. The part number on the Pc board inside is60-08241, and the designation is AMTEL CLASSIC. I have some limited programming instructions from the client, but I need to know the interconnect on the terminal board inside, i.e. terminals for the power, AC?DC? voltage? Door lock contacts? Pick up the phone, hit a four digit number, person answers, and hits a touch tone to let you in. Does anyone have anything on this unit? I can send you pictures if that will help.
