The ConnecT 56K DSU has an eight-position modular jack labelled

“TELCO.” The connector is used for connecting to the network when the

The primary DTE should be connected to either the RS-232 DTE

connector or the CCITT V.35 DTE connector. The maximum cable

lengths recommended are 50 feet for the RS-232, and 100 feet for the

CCITT V.35. The pin assignments for the connectors are listed in

Table 2-2, “Pin Assignments for Primary RS-232 Connector” and

Table 2-3, “Pin Assignments for Primary V.35 Connector”.

The V.35 connector is recommended for use with data rates above
