The Pin pattern and identification is as noted above for the fifteen (15) leads unused from the V.35 connector and the six (6) leads unused through the patching function. Any one of the fifteen leads to a maximum of six may be routed through the patch mechanism by means of straps if the user desires to bring more than the 19 lead V.35 interface through the patch mechanism. The procedure to follow to add a lead through the patch mechanism is simple. Assume you desire to bring lead EE through the patch mechanism on a DTE-A, DTE-B, and DCE module. Simply add a strap from E2 to EE on each of the three connector units on the FFM-01 or FFM-02 Subboard and lead EE is now routed through the patch mechanism and also switched from A to B if that action occurs. The procedure for the interface modules is the same. A strap added from E2 to EE on the top port will cause EE to appear at the top port only. If it is to appear also at the bottom port the additional strap must also be added there.
