IP based RNC Sync requirements

Hi guys,
This is my first topic here and won't be last.
We are building a new UMTS network and the vendor suggested that there is no need for RNC clock source since it is IP based (both A and Abis)
Thanks.

Hello

Hello,
If this is RNC then it must be Iu interface not Abis. Yes if this interface is over IP. Then no need for clock sync , as it is required in case of ATM. In IP case, control plane will be on Sigtran ( M3UA) and the User Plane will be on RTP.

Thanks

actually it's a dual mode BSC/RNC all based on IP

Hi~~ Dose SIGTRAN need 1588

Hi~~ Dose SIGTRAN need 1588 protocal to deliver clock from CN to NODE ?

if M2PA then sync is not

if M2PA then sync is not needed.
Node and CN should refer to same source for clock but is is not necessary to be 1588
