Allow Multiple Attendants to Answer Sequenced
Calls While Eliminating Call Crashing
The SQRG-12 Sequential Ring Generator is
designed for applications where more than
one person answers incoming calls and
those persons may be in locations where the
TMS-6X or TMS-12A is not visible.
The SQRG-12 eliminates confusion about
which line to answer next by displaying the
oldest call as a ringing line on all phones in
the phone system.

requested, this number must be provided to the telephone company.
The REN is used to determine the number of devices that may be connected to a telephone line. Excessive REN's on a
telephone line may result in the devices not ringing in response to an incoming call. In most but not all areas, the sum of
the REN's should not exceed five (5.0) To be certain of the number of devices that may be connected to a line, as determined by the total REN's, contact the local telephone company. For products approved after July 23, 2001, the REN for
this product is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the
REN without a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
The plug used to connect this equipment to the premises wiring and telephone network must comply with the applicable
FCC Part 68 rules and requirements adopted by the ACTA. If your home has specially wired alarm equipment connected

The SQRG-12 is a sequential ring generator option for use with the TMS-6X and TMS-12A. The SQRG-12 will re-ring lines for the
KSU/PABX based on line status information from the TMS-6X or TMS-12A.
The SQRG-12 is designed for applications where more than one person answers incoming calls, or in locations where the TMS-6X or
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 re-ring all calls that are ringing or holding within the call sequencer. This is
required in many P ABX applications and some key system applications to prevent call crashing (glare) problems when the C.O. lines connected to the TMS-6X or TMS-12A are also used for outgoing 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, or the TMS-6X has special software “TMX-PRAL” installed.
A. SQRG-12 Operation when Ringing Calls in Sequence
When the SQRG-12 is used with loop start C.O. lines, and you want the calls to ring through to the telephones in sequence (one at
a time), use J2 to block C.O. ringing from passing to the PABX or KSU. As a call rings in, the TMS-6X or TMS-12A detects the ringing, and tells the SQRG-12 to ring that line through to the PABX or KSU (only if this line is the oldest call). If a live operator does not
answer, the TMS-6X or TMS-12A will answer the call, play the message and put the caller on hold, while continuously commanding
the SQRG-12 to re-ring that line into your system. As new calls ring in on other lines, the SQRG-12 blocks these calls from ringing
through to the PABX or KSU until they have become the oldest call. Once an operator answers the oldest ringing call, the TMS-6X
or TMS-12A will begin ringing the next oldest call through to the PABX or KSU. This process of ringing calls through one at a time
will continue until the operators have answered all holding or ringing calls.
B. SQRG-12 Operation when Ringing All Calls
When the SQRG-12 is used with either loop or ground start C.O. lines, and you want all holding or ringing calls re-rung through to
the telephones, use J1 to pass tip ground (for ground start trunks), and ringing through to the P ABX or KSU. Note internal DIPswitches 1 through 12 must be set to OFF anytime you use the J1 jack. The J1 jack is a straight through jack, so in the idle state, the C.O.
tip and ring are passed straight through to the PABX or KSU. When the TMS-6X or TMS-12A recognize that there is an incoming
call on a line, the call sequencer commands the SQRG-12 to re-ring that line along with any other lines that are ringing or holding.
While the SQRG-12 is ringing a given line position of the PABX or KSU, the SQRG-12 constantly maintains a grounded tip condition
(for ground start lines), supplies -48V DC battery on the ring side of the phone line and superimposes its high voltage ringing on this
- 48V DC. This is purposely part of the SQRG-12 design to give the ground trunk card in the PABX or KSU the impression that the
line is a ringing line that has never been answered, even though the TMS-6X or TMS-12A may be holding a call on that line. All calls
will continue to ring through to the PABX or KSU until the call is answered by a live operator, or the caller hangs up (abandons).
Although the J1 jack was designed for ground start C.O. lines, it also works properly for loop start C.O. lines when using the “ring all
lines” mode.
