NxT1 HSSI/V.35 Option Module (P/N 1200346L2)

V.35 is possible with the NxT1 HSSI Option Module with an appropriate adapter cable (ADTRAN P/N 3125I081@A); however, some HSSI menu options will be unavailable in this mode (see User Interface Guide section for details). Table 29 (below) and Table 30 on page 45 give the pinouts for the V.35 and RJ-48C (T1) connectors, respectively.
