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 Option (AT&J)
Telco displays only on U. S. A. and Canadian 326X Series Modems. It is used to
select the RJ-jack type. Telco corresponds to the AT&J command as follows:
Telco Jack Selection Dial Transmit Level
RJ11C (Permissive) -9 dBm
RJ45S (Programmable) Programmable transmit level. The transmit level is -12 dBm if pins 7
and 8 on the jack are open (not connected).
Otherwise, the transmit level will be determined by the programming
resistor value (contact the Telco for further information).
