Does anybody have a good diagram showing how to wire a 202 D mount to a 685A subset with a 6 wire cord so that the F terminal on the 425 network is used, providing a dial filter?

I haven't been able to find the CRPF topic that discussed using 6-conductors.
However, here is a diagram for a 212 that does use the F-RR dial filter and 5 conductors:

502-320-401 issue 1 in the TCI library.

Just ignore the bottom 3 wires since these contacts are not in a 202 or 211.

Changes for 202 compared to 212:


212 (as shown in diagram)                    202

6-pair inside wire:                                 D5 (or D6) mounting cord:

W-BL                                                   Green     (Connect to green on hook switch in 202)

BL-W                                                   Red        (Connect to R terminal on right in 202 base, along with red handset wire)

W-O   (from B terminal in 212)              Black      (Connect to black handset wire in 202 using your own junction)

O-W   (from BL terminal in 212)            Yellow     (Connect to BK on dial in 202)   

W-GN                                                  White      (Connect to Y on hook switch in 202)

                                                           Blue        (not used)


G handset:                                           E1 or F1 handset:

Black to B terminal on block                 Black to B in 685A subset

Red to R terminal on block                   Red to R terminal on right

White to R terminal on block                N/A

White to W terminal on dial                 White to W on dial   

Note that when using a 685A subset, the black handset wire does NOT connect to BK on the dial
