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.

I. Expanding the Announcement Length

The TMS-12A ships with 32 seconds of high fidelity recording capability. Forty seven seconds of recording time is
possible at a lower fidelity by placing protocol switch 4 in the up position. A total of 2 minutes of high fidelity or 3
minutes of lower fidelity recording is possible with the addition of the Viking DRAM-1M (Fax Back Document 055)
memory expansion kit. For faster call processing, make your answer and pacifier announcements short.

Operation

A. Day Mode

In the DAY(3) or DAY(5) mode of operation, the TMS-12A will answer on the number of rings programmed (1, 2, 3
or 5) as explained in Programming, section B. This allows your receptionist to answer the phone first, if she is
available. After answering a call, the caller will hear the recorded greeting message. While this message is playing,
no other calls can be answered, but all calls that have met the ring delay will be answered as soon as the message
is finished. It is advisable to keep this message as short as possible. After the greeting has played, the caller is
placed on hold and the line that the oldest call is holding on will be displayed on the front panel of the TMS-12A or
on the optional TMS-RDMA remote display (see section D. Options, below). The call may then be released to the
receptionist by picking up that line.
released, the line that the next oldest call is holding on will be displayed.

Note: Only the oldest call may be released.

When the oldest call has been

While holding, and if recorded, a “Pacifier” message will be played approximately every 30 seconds.
If a call has been holding for longer than 4 seconds, the TMS-12A or TMS-RDMA will produce a double warble tone

audible signal (hold reminder tone) every 4 seconds.

B. Night Mode

In the NIGHT mode, the call will be answered after the programmed ring delay, the night message will be played
and the call will be disconnected.

C. Data Retrieval

In any mode of operation other than remote programming, statistics for Calls Abandoned, Calls Answered, and
Inbound Calls can be viewed.

1. Hold in the data switch, the display will show the current statistic total for the item highlighted by the LED (ABN,
ANS or INB).

2. To select the next statistic, momentarily release, then depress the data switch, and the next statistic item will be
highlighted.

3. The statistics can be reset to zero by depressing the reset button on the front panel of the TMS-12A.

Notes: This will reset the microprocessor and statistics only, the recorded messages will not be lost. However, any

calls holding in the TMS-12A will be dropped. This reset should only be done at a time when the TMS-12A is not
processing calls.

D. Troubleshooting

If the TMS-12A does not release the call to the key system or PABX, follow steps 1 - 3.

Note: This is usually

caused by high line current from the C.O. or PABX when the system is located close to a central office.

1. Measure the voltage across tip and ring when the key system or PABX has seized the line. The voltage must be
less than 11 volts for the TMS-12A to recognize that the key system or PABX has gone off-hook and that it
should release the line.

2. If the voltage is greater than 11 volts, install (2) 150 ohm, 1/2 watt resistors (included) in series with both tip and
ring as shown below.

Technical Support.

Optional Equipment

A. Using the TMS-12A with the SQRG-12 Sequential Ring Generator

The SQRG-12 Sequential Ring Generator is designed for applications where more than
one person answers incoming calls, or in locations where the TMS-12A front panel
display is not visible. The SQRG-12 eliminates confusion about which line to answer
next by only ringing the oldest call to the key system or PABX.

In some applications it is desirable to have the SQRG-12 ring all calls that are ringing
lines or calls that are holding on the TMS-12A. This is required in many PABX

applications and some key system applications to prevent call crashing (glare) problems
when the C.O. lines connected to the TMS-12A are also used for outbound calls by the PABX or KSU. The SQRG-
12 is capable of this mode of operation when DIP switch 3 on the TMS-12A is in the on position (see Programming,
section B).

For more information on the SQRG-12, retrieve Fax Back Document 060.

when

B. Using the TMS-12A with Remote Displays

Remote displays allow the TMS-12A to be installed in the phone room rather
than on the receptionist’s desk. They will

than

display the line that the oldest call is holding
on and provide a common audible warble
while calls are holding.

LM-12W, retrieve Fax Back
Document 665.

For more information on
the LM-24D, retrieve Fax

Back Document 670.

C. Additional Call Statistics

As an upgrade package for the TMS-12A, the TMS-STATS allows the user to collect more detailed call activity
information. The kit includes both serial and parallel interface boards and a special ROM chip. The serial interface
board allows the TMS-12A to be connected directly to the serial port of a personal computer while the parallel
interface board is provided for interfacing with standard printers. For more information, retrieve Fax Back

Document 080.
