Tip/Ring telephone sets connected to the Merlin System
through a BTMI cannot use Port Saver/ Trunk Saver op-
eration. The BTMI wiII not transmit the required
hook-flash signal.
System 75 requires a pound (#) to be dialed at the end
of every dial string. This is required to send the dialed
number to the trunk port.
Tip/Ring telephone sets cannot be used in this mode to
access the AT&T Door Phone.
For PARTNER telephone sets not equipped with a Re-
call button, “FEATURE 03” must be dialed to send a
hook-flash signal to the trunk port.
In the Ringdown mode, no number should be pro-
grammed in the AT&T Door Phone for it to dial when
the door button is pressed. The PARTNER Plus system
should be programmed to alert the desired stations
when the door phone goes off-hook on its station port.
The information for this system is based on engineering
judgment.
