System Clock. There are three possible
messages associated with this ALERT :-

(When No BRI is in Sync or when the BRI that
was supplying system clock loses sync)
or
ALERT System clock gained from
BRI-n
(When a BRI acquires sync and provides
system clock)
or
ALERT System clock lost from BRI-n
(When a BRI loses sync and the next source
is hunted as appropriate)
Where n is the port number, 1 to 4
These ALERTs are only generated when the
CBUQBR is in Clock Master mode.

Where x and y are in the range 0 - 8 and :-
x is the number of channels in use
and y is the number of channels remaining
available
x + y = 8
