3.7.5 Line Connection ['l']
Description
A line connection is a connection which occupies all timeslots, full line
rate for example, on 1 interface, but is not in RAW mode. This line would
look like this:
l bit_offset ifc_num
The
bit_offset
field is always
0
. There has been no use for this at the
present time. In order to configure a line connection on interface
0
it
would look like:
l 0 0
3.7.6 RAW Connection ['r']
Description
A RAW connection is a connection which occupies all timeslots on 1
interface and is in RAW mode. RAW mode is when no
de-framing
, or
un-bitstuffing
is done. Just the straight data from the timeslots read by
the firmware. This line would look like:
r
ifc_num
In order to configure a RAW connection on interface 4 it would look like:
r 4
3.7.7 Sub-channel Connection ['s']
Description
A sub-channel connection is an HDLC connection which occupies 1, 2, or
4 conectutive bits within a timeslot on one interface. The line would look
like this:
s bit_offset ifc_num ts_num ts_mask
The
bit_offset
field is always 0. So far, we have no use for it. In order
to configure a connection on interface 6, timeslot 2, bits 0-3 would look
like this:
s
0
6

1 bit equals 8 kbps. For example, 1 timeslot at 64k consists of 8kbps in a
sub-channel. An 8kbps time channel extends 2x8 to 16k, 4x8k to 32k.
1 Timeslot [64k]
8 8 8 8 8 8 8 8
