Understanding on standard buffer capacity for busty traffic on Multiplexer

Request support in understanding buffer capacity of a Multiplexer card and how is it calculated.
Are there any standards for buffer capacity when an Ethernet card is designed?

Issue details provided.Any related info ,please feel free to ask.It would we great if someone could help me with this issue as we have reached a standstill at present.Thanks in advance!!

 

Issue and Analysis

Ping Packet drops observed(1% loss in 10000) while pinging from one router interface(1 gig on GSR router)to another,which is connected via a multiplexer link(EoSDH).On changing the link to another Multiplexer Ethernet card (EoSDH) there are no ping packet drops observed.On checking the packet capture of the traffic on the Ethernet port of router and plotting a graph using an IO plotter for 10 msec ,there are nil/very minute burst observed on the traffic.But on checking the   1 msec IO graph there were huge no of burst observed on the traffic.We had put shaper on the GSR router outbound traffic but still there were spikes in traffic in capture.We had also tried policer on the Router port also but also there were burst in traffic. 

We had found that buffer of two cards used in multiplexer was different and initial card was having a lesser buffer than the second Ethernet multiplexer card.

1) Would like to know is they a way i can fine tune traffic to control the burst in traffic(GSR router) so that same Multiplexer card can be used?
2)What is the standard buffer capacity for the EoSDH Multiplexer card/port and how is it calculated?
3)Is there any other alternate methods to resolve the issue with the old setup?
