I'm having drops in the Circuit Emulation


I'm having some drops in the circuit emulation between BTS and BSC connection. Did a ping from the BTS router to the BSC router and  there is no packet loss ou high delay. Could someone help? I'm finding that the drops are being caused by jitter, there is a link with DWDM transmission in the middle. Perhaps the DWDM is not configured correctly.

ping X.X.X.X size 1600 df-bit 

Type escape sequence to abort.
Sending 5, 1600-byte ICMP Echos to, timeout is 2 seconds:
Packet sent with the DF bit set
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/8 ms
