* Note: Earth Ground is only required in ground start applications.
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.
