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 communications. 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:
Option Setting
AT Command
RJ11C 0,
1
RJ45S 2
RJ16C 3
RJ4MB 4
DECLARING THE JACK TYPE
Once 326X Ready displays, you must declare the jack type you need to connect your modem to the dial/leased
line so that the modem recognizes this connection (see Tables C-16 or C-18). You can declare the jack type as
follows:
1)
Press until TELCO OPT’S is displayed.
2)
Use to move through the TELCO OPT’S menu until Telco = jack type is displayed. For
example, you may see Telco = RJ16C in the display.
3)
Press until you see the jack type you used to connect your modem to the dial/leased line. For
example, you can select Telco:RJ11C.
