Channel
Framing is required to recover the channelized E1. In transparent operation,
the framing is configured as Unframed. In this case the G.SHDSL framer must be
set to Nx64 with N=32. For any framing such as FAS or CAS, the G.SHDSL framer
must be set to E1, then the E1 framing here may be set accordingly.
The cross reference table between Channel and Framing:

FAS
Frame Alignment Signal uses a 7-bits pattern to establish
and maintain the frame synchronization. The FAS word
is located in timeslot 0 of frame. In FAS mode there are
1~31 timeslot available for use data.
CAS
Also known as time slot 16 multi-framing. It requires a
multi-framing alignment signal to be present for frame
sync. The Multi-frame Alignment Signal (MFAS) is
inserted into the 16th timeslot of frame 0 of the 16-frame
multi-frame.
In CAS mode, there are 30 channels available for user
data. If timeslot 16 is included in the unit’s mapping, it
will be disregarded.
