Displays the data rate at which each USSI port is currently operating. A port's data rate is determined by
the number of DS0s assigned to it and the rate per DS0 associated with the active maps.

A rate mismatch exists between the DTE clock and the network-side
clock (as set by DS0 assignment).
The USSI port is not able to lock onto the clock provided by the
network interface.
The DTE is sending an excessive number of consecutive zeroes to the
network interface.
The DTE is not providing an external transmit clock. This alarm
displays only if the USSI port is configured to get its transmit clock
from the DTE.
A packet endpoint has detected missing or incorrect framing.
