DIP Switch Function
1
Sets unit for either Station access or Trunk (Loop Start
and Ground Start) access.
2
Determines if Loop Start or Ground Start trunk access
will be used.
3
Determines if a Pre-Announce tone is to be heard in
handset and paging speakers (set to 0) or if a Confirmation
tone is to be heard in handset only (set to 1).
4
Determines if the VOX timer will operate. Set to 0 to
enable the VOX Timer, or 1 to Disable. Only applies to
Station Access mode or Trunk Timer feature use.
5
Sets unitʼs delay before answering a station access
page to immediate answer (set to 0), or to answer after
1st ring burst (set to 1), (station mode only).
6
Sets unit to detect (set to 0), or ignore CPC pulse (set to 1).
A CPC pulse is issued by certain equipment when the
calling party has hung up (station mode only).
7
Determines if the Trunk Timer function will be used (set
to 0), or not used (set to 1). See Trunk Timer Features
section for description of function.
8 / 9
Switches 8 / 9 are used together to set the range for
the Paging Time control or to disable the Paging Default
timer, 0/0 = 1- 50 sec, 1/0 = 50 -100 sec, 0/1 = 100 -200
sec, and 1/1 inhibits the timer.
IMPORTANT NOTE:
DO NOT inhibit all of these disconnect features at
once. One of the 3 methods for the TAMB2 to disconnect from a station
port must be enabled. If you disable both timers and the
CPC-detection, or the PBX/CO does not issue CPC pulses when the call-
ing party hangs up, there will be no means for the TAMB2 to
disconnect from the call. You will need to cycle the DC power to the
TAMB2 to disconnect the call.

The contact closure contact set is provided to signal to external equipment the TAMB2ʼs
operational state. The contact set is single pole, double throw, and changes state from what
is screened below the terminals when the TAMB2 becomes active and returns when the unit
becomes idle again.
