There are two main types of ISDN network terminals: basic rate BRI) and basic group rate PRI ). All interfaces provided by the Telecommunications Board to common users are BRI interfaces. The original twisted pair wires can be used at a rate of 144K

To ensure the synchronization between the UE and the base station, you need to maintain the uplink synchronization of the UE, that is, you need to adjust the scheduled time of the UE.
Enodeb checks the UE's reference signal (RS) to determine whether the UE is synchronized with the base station. If there is a synchronization d
