1.7.1.3 Central D-Channel Processing
In this application the EPIC 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 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 to four 16-kbit/s channels.
