Hi Team,
The router ASR1006 we have P2P link terminating on serial interface ( channelized E1 ) which has ppp encapsulation . But suddenly yesterday 6 of our P2P link went down while troubleshooting we observed when we use hdlc as encapsulation link came up . Further on troubleshooting we removed the working link ppp encapsulation and reinsert the ppp encapsulation back but the link didn't came up . We have checked at remote router , and confirmed that on it encapsulation is also ppp . Also service provider confirmed that there is just a transmission in between those P2P which went down , and they don't have provision to set any encapsulation on there end.

NAME: "SPA subslot 0/3", DESCR: "8-port Channelized T1/E1 to DS0 Shared Port Adapter"

Further with troubleshooting , we have terminated the P2P link on the different router and found the P2P link UP with PPP encapsulation .
Also attaching the respective logs for the same & provide me further suggestion on this case if these cards gone faulty at the same time or some other issue
The sample configuration is below,
