The connection establishment fails
Diagnostics
The modem connection is made, but the remote connection establishment fails. The DCD
LED on the TS module or modem lights up and goes dark again (CONNECTED LED with TS
Module GSM).
Remedy
1. Check the user name and password in the "Parameters > Outgoing Calls" tab.
2. If you are using an ISDN connection, make sure the B-channel settings of the two ISDN
TAs match.
3. Now do the following, depending on the connection type:
Connection via TS module
Connection via an external ISDN-TA (connected
using TS Module RS232)
Connection to an ISP In the "Parameters > TS Module" tab
under the "Protocol for outgoing calls"
parameter, set HDLC-PPP or HDLC-
transparent.
In the "Parameters > TS Module" tab under
"Initialization 2", specify an AT command which
presets the B-channel protocol HDLC-PPP or
HDLC-transparent on the ISDN TA. You can find
the appropriate command in the manual for your
ISDN TA.
Connection to a dedicated
dial-up server
In the "Parameters > TS Module" tab
under the parameter for outgoing call
protocols, make the same setting you
made on the ISDN TA of your dial-up
server.
In the "Parameters > TS Module" tab under
"Initialization 2", specify an AT command which
presets the same B-channel protocol as you set
on the ISDN TA on your dial-up server. You can
find the appropriate command in the manual for
your ISDN TA.
