B-2 Access Manager 2000 User Manual
The modem must be configured to communicate at 2400 baud, 8 data
bits, no parity, one stop bit.
All the commands listed i n TableB-1, “Modem Configuration for OSI
Protocol (DTR Lead),” on page B - 3 through TableB-3 , “
Modem
Configuration for TABS Protocol ,” on page B-6 must be preceded by the
characters AT. For example, to disable character echo, type “ATE0&W”.
Otherwise, the following command should also be entered to cause the
modem to recall User Profile 0 on power-up:
AT&Y0&W
The “&W” command writes the changes to User Profile 0. See the
following tables:
■
Table B-1, “Modem Configuration for OSI Protocol (DTR Lead),”
on pag eB-3
■
Table B-3, “Modem Configuration for TABS Protocol,” on
page B-6
Be careful if you enter commands after you have completed the
Smartmodem configuration. Any subsequent commands at a different
baud rate may override the 2400 baud speed selection. The last command
entered and stored with “&W” determines the speed at which the
Smartmodem initially answers an incoming call.
Note: This configuration does not apply to CSUs and Controllers in the
OSI Mode. It is for use only with non-OSI Protocol CSUs or
Controllers.
To properly initialize the modem after it is configured, powered up, and
connected to the CSU or Controller, the CSU or Controller should be
powered down for a few seconds and then powered up again. This will
allow the CSU or Controller to initialize the modem and configure itself
The following devices operate with the configuration shown in Table B - 1,
“Modem Configuration for OSI Protocol (DTR Lead),” on page B - 3.
