The software is called "BTMon" (e.g., "BTMon_version_276.exe") and is 
(or at least was) readily available on the web.  Logging in to the 
2700 requires a password.  If it was changed by the telco, you will 
likely never get in.

I have worked with a number of these units and, particularly now, 
when mobile providers are transitioning to LTE and abandoning CDMA, 
it may be best to just keep the PRS10 and gut the rest.  I have one 
stock 2700 left, and the last time I turned it on it could not find 
any CDMA signals.  Also, even with a CDMA network available, 2700s 
were distinctly inferior to GPSDOs with respect to frequency 
stability.  The PRS10 can be disciplined with the PPS from a GPS receiver.

Best regards,
