Receptacles, Cables, and Pinouts

This section provides information about the HSSI cables you should use with the HSSI port adapter. Two types of cables are available for use with the HSSI port adapter: the HSSI interface cable used to connect your router to an external DSU (and HSSI network) and a null modem cable, which allows you to connect two routers back to back. Both HSSI cables are available only from Cisco systems and conform to EIA/TIA-612 and EIA/TIA-613 specifications.

HSSI Interface Cable

The HSSI cable (CAB-HSI1=) connects the HSSI port adapter with the external DSU. The HSSI cable is 10-feet (3.048 meters) long. The maximum HSSI cable length allowed is 50 feet (15.24 meters). Figure 1-5 shows the HSSI cable and the 50-pin connector used at each end of the HSSI cable. Table 1-1 lists the pinout.
