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.

Notes: If the PABX does not recognize lines on the TMS-6X as busy and call crashing is observed, set up those lines as “incoming only trunks” on the PABX. If those lines  
must be used for inbound and outbound calls, you must use the special software TMX-PRAL. Contact Viking product support at (715) 386-8666 for more information. Do not  
install bridging clips on any connections which connect the two halves of the punch down terminal block. Bridge clips should only be installed as a method of bypassing equip-  
ment. In order for the SQRG-12 to work properly, the four-wire modular jack must be installed between the TMS CONTROL LINE on the SQRG-12 and the SQRG jack on the  
TMS-6X or TMS-12A.

Operation  
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 old-  
est 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 PABX applications and some key system applications to prevent call crashing (glare) problems when the C.O. lines con-  
nected 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 oper-  
ation 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 ring-  
ing, 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 PABX or KSU. Note internal DIP switch-  
es 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.
