A telecommunications system (10) includes a first cross-connect switch
(12) and a second cross-connect switch (14). The first cross-connect
switch (12) includes a switching matrix that provides information from a
matrix connection to a selector (28) of an output interface (18). The
selector (28) places the information from the switching matrix onto one
or both of a working channel (24) and a protection channel (26). The
second cross-connect switch (14) receives the working channel (24) and
the protection channel (26) at an input interface (20). The input
interface (20) includes a selector (30) that checks a signal quality of
the working channel (24) and the protection channel (26). When necessary,
the selector (30) sends a request to the selector (28) to bridge the
working channel (24) onto the protection channel (26). According to the
signal quality, the selector (30) selects one of the working channel (24)
and the protection channel (26) for transfer to a switching matrix (22)
of the second cross-connect switch (14). The selector (30) avoids
creating and deleting matrix connections in the switching matrix (22) in
performing protection switches between the working channel (24) and the
protection channel (26).
