For checked the V.35 cables and the Wic1T, i need to make a local loop (B3) with a V.35 cable. With the V.35FC cable there is no problems, looping this pins:
J2·C-->J2·D (RTS-->CTS)
J2·E-->J2·H (DSR-->DTR)
J2·P-->J2·R (SD+-->RD+)
J2·T-->J2·S (RD- -->SD-)

the result is that the serial interface changes to looped status.
but the same procedure on the V.35MT cable don´t make the loop.
I try this but the interface don't change to looped status:

J2·P -J2·Y --> J2·R (SD+ --> SCT+ --> RD+)
J2·S -J2·AA --> J2·T (SD- --> SCT- --> RD-)
J2·U --> J2·V (SCTE+ --> SCR+)
J2·W --> J2·X (SCTE- --> SCR-)
J2·C --> J2·D (RTS --> CTS)
J2·F -J2·H --> J2·E (RSLD --> DTR --> DSR)

¿Any suggestion? Thanks!

I think i found the solution, here is:

For DTE V.35 Cable loop back the pinout is the next:

J2·C --> J2·D (RTS --> CTS)
J2·F - J2·E --> J2·H (RSLD --> DTR --> DSR)
J2·P --> J2·R (SD+ --> RD+)
J2·T --> J2·S (RD- --> SD-)
J2·V - J2·AA --> J2·U (SCTE+ --> SCT- --> SCR+)

Whit this the serial interface shows the looped status, there are imput and output packets whitout CRC errors,
I think is ok but if somebody tell me your opinion, I would be grateful !.
