Dial and Leased Line Transmit Levels

Dial Line Transmit Level

Your 3260, 3261, 3262, or 3263 Modem does not support the DL TX option. You
select the dial line transmit level through the Telco option in the TELCO OPT’s
category. Use the following as a guide:

Leased Line Transmit Level

Front Panel Option: LL TX Level

Factory Default: 0 dBm

The leased line transmit level for the 3260, 3261, 3262, or 3263 Modem is adjustable
from 0 to -15 dBm in 1 dBm increments.

Making Telephone-to-Modem Connections

To use a telephone with your modem, connect the telephone cable to the PHONE
jack at the rear of the modem.

Connecting an Exclusion Key Telephone

In some cases, you can connect an exclusion key telephone to the modem for manual
dialing and answering or normal voice communication. This allows you to answer
and initiate calls manually with the telephone and then connect the modem to the line
by switching the exclusion key. Install an exclusion key telephone as follows:

1) Connect the exclusion key telephone to the RJ36 jack if your modem is

connected to an RJ4MB/RJ36, RJ45S/RJ36, or RJ16C/RJ36 combination.

2) Connect the 8-pin modular cable from the modem DIAL LINE jack to the

RJ11C, RJ4MB, RJ45S, or RJ16C data jack.

Connect the exclusion key telephone to the PHONE jack on the rear panel if
your modem is not connected to an RJ36 jack combination.

3) From the TELCO OPT'S menu, set the Telco option to a jack type (RJ16C,

RJ45S, or RJ4MB) supporting the exclusion key feature.

Telco Jack Selection
