Problem

Diagnosis/Test

Possible Solution

If operating the 326X Series Modem on a leased line, and you experience this type of problem...

Modem won't connect

NOTE: CQMS parameters are only valid once the modems are connected (in data mode)

Check leased line cable for conformance to 2- or 4-wire pinouts (U.S./Canada only).

Ensure one modem is set for answer and one for originate.

Ensure modem is set to match line type (2- or 4-wire).

If you are still experiencing problems, run an LAL pattern test on both modems.

•For a 3261 2-wire leased line cable, pinouts should be Pin 1 (ring) and Pin 2 (tip)

•For a 3261 4-wire leased line cable, pinouts should be:

—Pins 1 (TX Ring) and 2 (TX Tip)

—Pins 7 (RX Tip) and 8 (RX Ring)

For pinouts for your country and model, refer to Appendix C.

•Confirm the Tx and Rx connections for your leased line jack.

•If errors are found on either end, contact Telenetics Customer Support or your local distributor.

•If the LAL pattern test passes, you may have line problems; contact your telephone company.
