NxT1 HSSI Option Module (P/N 1200346L1), 50-Pin SCSI-II
The NxT1 HSSI Option Module uses a single 50-pin SCSI-II interface to combine up to eight T1s of data
(four from the NxT1 HSSI Module T1 ports and four from other T1 ports installed in the system). Table 26
gives the pinouts for the SCSI-II connector, and Table 28 on page 45 gives the pinouts for the RJ-48C (T1)
connector.
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 (for details, see
the
User Interface Guide
section). Table 27 and Table 28 on page 45 give the pinouts for the V.35 and
RJ-48C (T1) connectors, respectively.
