Because the presentation of HDLC encoded data on the physical interface is lsb first, the lsb is
right-aligned in the transmit and receive shift register.
A D-channel byte is formed by concatenating two D bits from each of four frames. This data is also
right-aligned in the D-channel receive register as shown in
13.2.3.4
As with the B channel, a mechanism is provided to support incoming D channels containing unencoded
data, even though as of this document’s publication date, no communication protocols using unencoded
D-channel data are known.
As with unencoded (PCM encoded) B-channel data, it is assumed unencoded D-channel information is
presented on the physical line msb first. The msb is left-aligned in the transmit and receive shift register,
that is, the first bit received is aligned in the msb position through to the last received bit of a byte that is
aligned in the lsb position.
A D-channel byte is formed by concatenating two D bits from each frame over four consecutive frames as
shown in
