While you are trying to have a call on a mobile phone connected to TEMS Investigation, you may face an error like this:
An error concerning RAS occured, State AuthNotify. 734.0: The PPP link control protocol was terminated
Indeed, this isn’t a specific problem for TEMS, see below.
This is a common problem for Point-to-Point Protocol (PPP) dial-up connection. So, Microsoft has a help page for that. It says:
- Click Start, point to Settings, and then click Network and Dial-up Connections.
NOTE: For Windows Server 2003, click Start, point to Control Panel, and then point to Network Connections.
- Right-click the appropriate dial-up networking connection, and then click Properties.
- Click the Networking tab, and then click Settings.
- Click to clear the Negotiate multi-link for single link connections check box (if it is selected).
- Click OK, and then click OK.
- Double-click the connection, and then click Dial.
- If this procedure resolves the issue and you can establish a dial-up connection, you do not have to follow the remaining steps in this article.
- If this does not resolve the issue and you cannot establish a dial-up connection, go to step 7 to continue to troubleshoot this issue.
- Right-click the connection, and then click Properties.
- Click the Security tab.
- Under Security options, click Allow unsecured password in the Validate my identity as follows box, and then click OK.
- Double-click the connection, and then click Dial to verify that you can establish a dial-up connection.
If the first resolution doesn’t work, try this one. There is useful information about this problem in TEMS Investigation help file:
- PDP Context Activation failure. See the Activate PDP Context Reject message in the Layer 3 Messages window for the cause value.
- The phone lacks an APN for the network. Try setting the APN by sending the following command to the phone: AT+CGDCONT=1, “IP”,”my_server.com” (replace the final string by the correct URL).
