Our device is set up to provide AT Commands directly to nRF9160 using a USB UART connection and control using a VT100 Terminal simulator. When attempting to connect to the R&S CMW500 Call Box, our device sees the Call Box, but there is no connection established.
According to COPS command... our device finds the CMW500... 
Note: We already made sure that the CMW500 is able to connect to a golden sample using nRF9160, so the settings on CMW500 appear to be correct. All we simply did was ensure that the Call Box was ready, power on our device and ensure that the Module was on with AT+CFUN=1 command.
Is there another command(s) to get the devices to properly communicate to result in a "Connection Established" so that then an AT command script can be run while communicating to the Call Box? This is a requirement from a government Test Agency.
