1.6.1.5 Central D-Channel Processing
In this application the EPIC-1 not only switches the B-channels and performs the C/I-
and monitor channel control function, but switches also the D-channel data onto the
system highway. In upstream direction the EPIC-1 can combine up to four 16-kbit/s D-
channels into one 64-kbit/s channel. In downstream direction it provides the capability to
distribute one 64-kbit/s channel in four 16-kbit/s channels.
