channel of a disabled D-channel is not manipulated by the control
channel master. It passes the value stored in the EPIC-1 control memory
(C/I or MR must = “blocked”). The disabling of a D-channel has an
immediate effect also when the channel is active. In this case the
transmitter (HDLC-controller in the subscriber terminal) is forced to abort
the current frame.
The control channel of an enabled D-channel is manipulated
a) by the control channel master, if AMO:CCHM = 1,
b) directly via DCE, if AMO:CCHM = 0.
