EN_B2H
EN_B1H
The bits EN_D, EN_B2H and EN_B1H are used to select the timeslot length for the D-
channel HDLC controller access as it is capable to access not only the D-channel
timeslot. The host can individually enable two 8-bit timeslots B1- and B2-channel, i.e.
the first and second octett, (EN_B1H, EN_B2H) and one 2-bit timeslot D-channel
(EN_D) on IOM-2. The position is selected via HCS.
