T1 channels on the same CPOS physical interface can use different clock modes,
depending on connected devices. For example, when connected to a SONET/SDH
device, a T1 channel should use the slave clock mode, and when directly
connected to another device with fiber-optic, it can use either mode so long as the
mode is different from the one used at the opposite end.
Note that different T1 channels of the same CPOS physical interface are
independent of one another in terms of clock mode.
