NxT1 HSSI/V.35 Option Module

The NxT1 HSSI/V/35 Option Module (P/N 1200771L1) uses a single 50 pin SCSI-II interface (or V.35
interface using an optional adapter cable) to combine eight T1s of data (a combination of eight using the
four NxT1 HSSI/V.35 Module T1 ports and other T1 ports installed in the system). See Pinouts 30 and 31.
