5.2 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.
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 equip-
ment) interface on an DB-25 female connector. As a DCE, this interface
is designed to connect to DTE equipment, such as a router. When con-
necting the V.35 interface of the Model 3088/CA to your DTE device, use
a V.35 straight-through cable (See figure 6). Appendix C 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 dia-
grams in Appendix C as a guide.
