Questions:
(1) In iBasis coverage document released 2022-04-07 what do the value pairs, in seconds, mean in the right hand most four columns?
(2) Does iBasis support periodic-TAU (Tracking Area Update) extended timer encoding, or only the older periodic-TAU? In which regions?
(3) Using eDRX as a power savings mode, is there any necessary negotiation between User Equipment and provider, to establish UE registration persistence?
