Hi everyone, could somebody tell me which phone´s brand or model will store the RPLMN in its file?
I mean, there are some phones which does not store the RPLMN and other ones does it,is it a matter of brand or model? I tried Nokia 6101 and it does not do it, but I do not have chance to test it in other Nokia models.
Thanks a lot.
I need some help to learn the drive test in GSM and WCMA. I am a beginner for this pls any one explain some basic testing of the device during INter RAT and what are the prameters need to check for this in QXXDDM
Line Reversal was used with Analogue Networks. Classic Coin and Fee Checks with Payphones.
For Signalling C7 / ss7 is ubiquitious. Some Networks (legacy
requirements) still support R2 MFC signalling.
For Landline solutions with a Local Loop (Two-Wire interface), a line reversal is used to provide “wetting current” before CLI is sent to the CPE. Line Reversal, FSK (CLI) followed by the Ringing Current (from the CLIC).
