V.35 ADAPTER

The V.35 adapter provides two V.35 ports. The card contains two female DB26 connectors. A V.35

adapter cable converts the DB26 connection to a standard V.35 connection. You can configure each

port for DTE (external clocking) or DCE (internal clocking), and each port supports data rates from

56 Kbps to 2,048 Kbps.

The V.35 supports network side connections, providing dedicated connections to other systems.

The adapter can take advantage of network connections such as NTT’s HSD-Y lines, DDS lines in

the U.S., and private network connections through a T1 multiplexer or a channel bank. The V.35

can also take advantage of switched network connections by using an external Data Service Unit

(DSU) or Terminal Adapter. The V.35 supports lead-controlled dialing to the Terminal Adapter.

ONNECTION

The V.35 interface is provided by an adapter cable that converts the DB26 connection on a V.35

adapter to a standard 34-pin V.35 connection.

Each port on a V.35 adapter has software configurable for DTE (external clocking) or DCE (internal

clocking). Be sure to use the appropriate V.35 adapter cable (DTE or DCE).

The DTE V.35 adapter cable provides a standard 34-pin connection with male contacts. The DCE

V.35 adapter cable provides a standard 34-pin connection with female contacts. The following table

shows the pin and signal assignments for the V.35 adapter provided by the adapter cable.
