TAMB2  
Telephone Paging Access Module  
The TAMB2 telephone paging access module provides a  
means of interfacing various analog telephone port types to  
a paging system amplifier to enable a facilityʼs telephone system  
to be used to make audio announcements over its paging  
system. The TAMB2 will interface to analog loop start and  
ground start trunk ports as well as analog ring-up station lines.  
It provides a means of connecting an external audio or music  
source that will play over the paging system when no pages  
are in progress. A set of contacts are provided to signal external  
equipment of the TAMB2ʼs operational status. Various DIP  
switches and controls provide a wide range of flexibility over  
how the access module will operate. The TAMB2 can be  
mounted on a wall, mounted as a single unit in a rack (optional  
rack mount kit required) or mounted 2-up, side-by-side in a  
single rack space.

Theory of Operation  
Loop Start Interfacing:  
(in the case of talkback paging equipment). Disconnection of  
the page happens when the loop start trunk goes on hook and  
loop current flow stops. In this mode, the TAMB2 responds to  
the status of the loop current flow and generally no timers are  
needed to control when it disconnects. However, a Trunk Timer  
feature is provided that can help prevent accidental lock-up of  
the paging system (see featureʼs description below).  
The TAMB2 provides a 24V DC talk battery on its T (tip) and  
R (ring) terminals. When it detects a DC loop current flow  
through these terminals, it will activate. Upon activation, it will  
produce an announcement tone and connect in the paging  
amplifier through an isolation transformer. The announcement  
tone can be set to be heard only at the paging phone or at both  
the phone and over the paging system. The TAMB2 allows  
bi-directional audio, both to and from the paging equipment  
Ground Start Interfacing:  
In addition to the tip and ring connections to this port, an  
additional connection between the TAMB2ʼs G/S terminal and  
the PBX ground must be established. When idle, the TAMB2  
opens an internal relay contact in series with its T (tip) terminal,  
and monitors for loop current flowing in its R (ring) terminal.  
When the PBX grounds the TAMB2ʼs R terminal, loop current  
flows and is detected. The TAMB2 responds by closing the  
relay contact in series with its T terminal. Once this connection  
is established, the TAMB2 will produce an announcement tone  
and connect in the paging amplifier through an isolation trans-  
former. The announcement tone can be set to be heard only at  
the paging phone or at both the phone and over the paging  
system. The TAMB2 allows bi-directional audio, both to and  
from the paging equipment (in the case of talkback paging  
equipment). Disconnection of the page happens when the  
ground start trunk goes on hook and loop current stops. In this  
mode, the TAMB2 responds to the status of the loop current  
flow and generally no timers are needed to control when it dis-  
connects. However, a Trunk Timer feature is provided that can  
help prevent accidental lock-up of the paging system (see  
featureʼs description below).  
Trunk Timer Feature:  
When interfacing to either loop or ground start trunks, a Trunk  
Timer feature can be enabled which will interrupt loop current  
flow to the PBX port for 1 second after either the VOX or  
Default time has expired. In many PBX systems this break in  
loop current will cause the connection between the TAMB2  
and the calling station to be cleared, allowing another caller to  
access the paging system. This is designed to protect the  
paging system from a phone that may have been hung up  
incorrectly and is locking out access to the paging system.  
In addition to enabling this feature, the Default time period must  
be set and/or the VOX timer must be enabled and its time set.  
Both timers do not have to be used, but at least one must be  
enabled for this feature to work.  
Station Port Interfacing:  
The TAMB2 answers the station port after it detects high  
voltage (90V) ring on the line. The unit can be set to answer  
the call immediately or after the end of the first ring burst. Once  
answered, the unit provides an announcement tone and con-  
nects the telephone line to the paging amplifier through an iso-  
lation transformer. The announcement tone can be set to be  
heard only at the paging phone or at both the phone and over  
the paging system. The TAMB2 allows bi-directional audio,  
both to and from the paging equipment (in the case of talk-  
back paging equipment). Since the TAMB2 cannot directly  
determine the state of the calling partyʼs phone, it must use  
indirect methods to determine when to disconnect. Discon-  
nection of the TAMB2 from the call is controlled through 3  
methods. 1) A default timer will drop the call after a preset  
amount of time has elapsed (1-200 seconds), 2) A VOX timer  
will drop the call after it detects no audio for a preset amount  
of time (1-11 seconds), 3) The unit will immediately drop the  
line if it detects a CPC pulse (break in loop current) from the  
PBX/CO port. Any of these disconnection methods can be in-  
hibited, however at least one must be enabled to ensure that  
the TAMB2 will disconnect.

Connections to Paging Amplifier Input  
Balanced Input Wiring:  
PAGE  
OUT  
The TAMB2 was designed to connect to a 600-ohm bal-  
anced TEL input. The amplifierʼs input sensitivity should  
be high enough that with 200mV input signal, the amp  
will be able to produce its full rated output power. If input  
sensitivity is not high enough, try using an unbalanced  
input with a WMT1A transformer (as shown below).  
600-ohm Balanced Input  
PT PR G/S  
IMPORTANT  
Keep Amp turned off until all  
wiring to the TAMB2 is complete  
Unbalanced, Hi-Z Input Wiring:  
Wiring to an unbalanced Hi-Z or AUX input normally requires the use of a WMT1A trans-  
former. The output levels of the TAMB2 generally cannot drive this type of input to full rated  
power since the AUX input is less sensitive than the specialized TEL inputs. The WMT1A  
provides about a 5X voltage increase in the ampʼs input.

PBX Loop Start Trunk Port  
CO/PBX Station Port Connections  
Wiring to the ground start trunk port requires a connection  
between the TAMB2ʼs G/S terminal and the ground of the  
PBX. The AC chassis ground for the PBX can typically be  
used for this connection.

Connections to a Music Source  
AUDIO OUT  
L
MUSIC SOURCE  
R
The TAMB2ʼs Music Input will combine a stereo signal into mono or a mono source can be connected to either of the two  
RCA jacks. The MUSIC control is used to set the level of the music source when playing through the paging system. Set  
the level of the page using the amplifierʼs level control, then use the TAMB2 music control to set the background music level.  
IMPORTANT NOTE: When using the TAMB2 in ground start trunk mode with a music source that uses a 3-prong  
grounded plug, it may be necessary to use WMT1A transformers to isolate the music sourcesʼ outputs from the TAMB2ʼs  
music inputs. The music sourceʼs signal ground, which may be connected to the the AC line ground, could create an elec-  
trical short with the connection from the TAMB2ʼs G/S terminal to the PBX ground (which is typically the AC ground for the  
PBX) causing the TAMB2 not to function.  
Power Supply Connections  
All operational modes of the TAMB2 require the connection of a user-  
supplied 24V DC power supply. The connection polarity is marked on the  
unit. The supply input is polarity-protected so that reversed polarity will  
not damage the unit, but it will not operate until the condition is corrected.

or greater  
(user supplied)  
When using multiple TAMB2ʼs in an installation, it may be more con-  
venient to use a single, user-supplied power supply and wire the  
power terminals of the multiple units together. When doing this, make  
sure the power supply is 24V DC and can supply 0.15A x the units  
being powered.  
Rotary Control Functions  
PAGING TIME  
This control is used to set the maximum paging time within the Paging Time Range  
set by DIP switches 8 & 9. MIN Time is the lowest time of the selected range, MAX  
Time is the longest time. The control is linear and the “tick” marks represent 5 or 10  
second (approx.) intervals, depending on range set, to make setting a specific time  
simple. The Paging Timer can be inhibited.  
VOX DELAY  
This control sets the period of silence that must elapse for the unit to determine that  
paging activity has likely ended. The “tick” marks represent 1-second (approx.)  
intervals. This timer can be inhibited.  
TONE  
This control sets the level of the audible tone that indicates that the paging  
connection has been established. The tone cannot be inhibited, but the volume can  
be turned down so it cannot be heard.  
MUSIC  
This control sets the level of an external audio source feeding the paging amplifier  
when no page is active.
