V.35 Interface Converter Cable Wiring

Table B-10 describes the V.35 interface-converter cable wiring. The 50-pin connector

on this cable connects to the 50-pin WAN connector on the SWAN concentrator, and

the 34-pin connector connects to a standard V.35 connector (4,5) with female contacts.

This cable presents special EMI problems because the modem connector itself is not

shielded. The 50-pin connector and the cable are fully shielded, however.

The four-bit ISEL value is %b0110.
