8.4 Malfunctions in remote maintenance
8.4.1 The partner is not answering
Error message on connecting
"Partner not answering"
Remedy
1. Check the phone cables and the power connection of the TS Adapter IE.
2. Check the SF LED on the TS Adapter IE. If the LED is lit, refer to the section "Error
Diagnostics Based on LEDs".
3. Check the DCD LED on the TS Adapter IE or on the external modem of the
TS Adapter IE. If it is lit, an outgoing connection is possibly active. To exclude this error,
set the "Connection establishment" parameter to "never" in the "Parameters > Outgoing
Calls" tab.
4. Also check the area code and country code of the phone number you use to call the
TS Adapter IE.
5. If you are using an ISDN connection, the following may have caused the error:
The ISDN TA on the PC does not signal the B-channel protocol to the remote station
when connecting. Automatic detection of the B-channel protocol by the ISDN TA on the
TS Adapter IE then fails.
As a test, set the B-channel protocol of the ISDN TA on the TS Adapter IE to match your
ISDN TA on the PC:
– For an internal ISDN TA, change this setting in the "Parameters > Modem > Internal
Modem" tab under "Protocol for Incoming Calls".
– For an external ISDN TA, you must add an AT command under the "Initialization 2"
parameter in the "Parameters > Modem > External Modem" tab. You will find the
appropriate AT command in the manual for your ISDN TA.
6. If you are using an ISDN connection, there is another possible cause of the error:
You have configured a multiple subscriber number on the TS Adapter IE and the PABX to
which the TS Adapter IE is connected is working with number suppression, meaning it
does not transmit the subscriber number when calling.
