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:
Declaring The Jack Type
Once 326x Ready displays, you must declare the jack type you used 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.
4) Press . In this example Telco = RJ11C is displayed.
You have now declared to the modem the jack type you are using.
If this is the first-time you are installing the modem, the modem is set
(factory default) for connection to an RJ11C permissive jack. Installation is
complete.
If this is not a first-time installation, connect the modem to an RJ45S
programmable jack and set the Telco option for this jack type. To use a
programmable jack, contact your telephone company to arrange for installation.
NOTE: You can also select the dial line jack type using the AT&J command.
Refer to Appendix A for details.
