Application Notes (for Compatibility Chart)

1.When used in any mode of a System 25, if the user initi- ates a call to the door and he wishes to enter the Option Selection mode, pressing three pound keys fol- lowed by the digit 3 (i.e., # # # 3, not # # 3) must be entered. Actually, the first # does not seem to be recog- nized at any time during the call. However, it should be noted that only # # 3 is needed to enter the Option Se- lection mode when the call is initiated from the door button press.

2.When sharing a trunk port on a System 25, that port must be configured as an “805” PBX/Centrex, not an “801” Loop trunk. This is the only way to transmit a hook flash to that port.

3.On the Merlin 1030/3070 tip and ring station application, there is a preset delay such that the Merlin system will disregard DTMF for the first 12 seconds of the connec- tion. In this mode, users have the choice of either changing that time period or waiting for it to time out for each call.

4.In general, the ring-cadence option selection applies only if there is an auxiliary alert device connected. All of the EKTS/PBX’s will “absorb” the ringing signal from the AT&T Door Phone Controller and generate their own ring cadence to the telephone sets.

5.When using the AT&T Door Phone Controller in any con- figuration with a Merlin System, the pound key must be pressed twice (##) for each pound (#) sent to the unit when dialing from a multi-button set.

6.Port Saver/Trunk Saver operation will not work for Tip/Ring sets. A switch-hook flash is not passed to the trunk port from these sets.

7.A trunk shared with the AT&T Door Phone Controller should not be placed in a trunk pool with other trunks.

8.When the AT&T Door Phone Controller shares a C.O. trunk, Trunk Saver operation is recommended.
