Explanation
Choose DS3 (T3), E3 or HSSI to match the type of link you are analyzing, then
choose the frame check sequence (FCS) standard: CRC-16 (the default) or CRC-
32.
You must set this to match the settings on the frame relay CSU/DSU.
If ATM or LAPB is the selected encapsulation method, you must choose the sub-
protocols on the link.
Check if your link is configured for fractionalized operation. Fractionalized DS3
and E3 are not supported.
Set to match the bandwidth and channel settings of the fractionalized HSSI link
under analysis.
