Chapter 3 - Unpacking & Setup

3.4Setup

Perform the following procedure to connect your cables and, if necessary, change to V.35 signaling on the data port.

1.If the DTE device has a V.35 interface, the internal shunt must be moved to the V.35 position and a V.35 adapter cable must be connected to the data connector (labeled “RS232”). Refer toV.35 Shunt for procedures on moving the shunt to the V.35 position. Refer to Appendix A for cable details.

If the DTE device has an EIA-232-D interface, a standard RS232 (straight-thru) cable can be used.

2.Connect the external wall transformer power supply to the DSU, then plug the power supply into a live AC outlet. The DSU has no power switch; however, when power is applied to the unit, the front panel LEDs will light.

3.Connect the DTE device to the RS232 connector on the back of the DSU.

4.Connect an RJ-48 phone cable to the LINE connector on the back of the DSU. Connect the other end of the phone cable to the local access line jack.
