HSS Interface connections
The connector on the high-speed synchronous serial interface is a high density
LFH-60 (as used on standard Cisco WAN port serial interface cables and
equivalents).
The interface specification (X.21 / V.35 etc) is automatically changed by simply
changing the type of interface cable connected to the HSS.
