Connecting the Model 3088/CA (V.35) serial interface
Model 3088/CA supports V.35 serial port connections. This section describes how to connect the serial ports
to your V.35 equipment.
Connecting the Model 3088/CA (V.35) to a “DTE” device
The Model 3088/CA provides a V.35 DCE (data circuit terminating equipment) interface on an DB-25
female connector. As a DCE, this interface is designed to connect to DTE equipment, such as a router. When
connecting the V.35 interface of the Model 3088/CA to your DTE device, use a V.35 straight-through cable
(see figure 8). Appendix D on page 78 describes pin assignments and signal sources for the Model 3088/CA
V.35 interface. When purchasing or constructing an interface cable, refer to the pin diagrams in Appendix E
on page 80 as a guide.
