Menu-8C Miscellaneous Management Configuration
When you select Miscellaneous Management, Menu-8C appears. Menu 8C allows you to
configure a variety of parameters including connection, phone numbers, timing and error thresholds.
Menu-8E Modem Initialization Strings
If you select Modem Initialization Strings, Menu 8E appears Each unit can have a maximum of
two modem initialization strings. The first string (
String 1
) can be equal to or less than 20
characters, and the second string (
String 2
) can be equal to or less than 60 characters.
To initiate a modem connection:
1. The unit sends
+++
, followed by the first modem initialization string.
2. The unit then waits for a response from the modem to guard against the possibility of
losing the characters immediately after the modem resets.
3. After receiving the modem response, the unit sends the second initialization string (if
this string is programmed). The Dual Trunk E1 Router assumes that the modem always
sends a response; therefore, do not program the modem not to send a response.
4. If using the modem reset command, you should program everything up to the reset
command as the first modem initialization string.
5. Program the remaining commands as the second modem initialization string.
