Installing an interface cable on the IPLink 2635’s V.35 interface port

The IPLink Model 2635 comes with a V.35 interface presented on a DB-25 female connector (see figure 10).

The interconnecting cables shall be acceptable for external use

and shall be rated for the proper application with respect to volt-

age, current, anticipated temperature, flammability, and

CAUTION mechanical serviceability.

The Model 2635 V.35 (DB-25) interface is configured internally as a DCE. However, when using the Patton cable with the 2635, the V.35 interface at the M/34 end of the cable is a DTE (see figure 11). In other words, the Patton DB-25 to M/34 cable is a sync null modem cable.
