On SDH provided service it should always be set to clock from
the line at both ends. On PDH, [i.e. DS3 E3 E1] one end should be internal
one should be clocked from the line.
I've seen certain cross connect and other devices that provide
framing [FR swiches etc] that break this rule, and its hard to tell
if its telco misconfiguration or vendor issues.
