TMS-12A
12 Line Call
Sequencer
September 11, 1998
Answer up to 12 Lines
The TMS-12A Automatic Call
Sequencer will answer up to 12
inbound lines promptly with a clear,
digitally-recorded voice announcement informing the caller that their
call will be taken by the first
available representative. The call is then placed on
hold. In addition, two TMS-12A’s can be cascaded to
support up to 24 lines.
Optional music and/or promotional announcements will keep the caller assured that
their phone connection is intact and will be answered soon. A pacifier message can
also be recorded to confirm that the call will be answered.
Call statistics as well as the line number of the oldest holding call will be displayed on
the LED. In addition, an optional ring generator, SQRG-12, may be added to provide
complete sequencer automation.

B. Master/Slave Wiring
Using an additional TMS-12A configured as a slave, up to 24 lines can be sequenced. In the master/slave
configuration, all recordings, statistics, remote access and answer protocols are handled independently between
master and slave.
To enable a TMS-12A to be a slave unit, set switch 12 to the up position, “SL” will be displayed on the display. The
slave lines will be displayed as lines 13 - 24 on the master TMS-12A, TMS-RDMA or the LM-24D. The pins shown
below must be tied together for master/slave operation.

The security code is used to gain access to remote programming and recording through line 12 only. To change the
security code, set the 16-position rotary CODE switch on the front of the unit to positions “1” through “9” only. This
will be your security code.
See sections D. Recording/Playback and E. Answer Protocols for more information on remote programming and
recording.

The ring delays are 1 and 2 in respect to the answer protocols (DAY(3) = 1, DAY(5) = 2, NIGHT = 1)
Normal ring delays (DAY(3) = 3, DAY(5) = 5, NIGHT = 3)
Only the oldest call will be released from the TMS-12A
The TMS-12A will release any call
The optional SQRG-12 will re-ring all lines being sequenced on the TMS-12A
