MAP MODE Determines the selection
method for the E1 sublink
time slots transferred to the
HDSL link.
Note:
The selected sublink time slots
are allocated the same time
slots in the HDSL link frame.
USER Free user selection of time slots
SEQ Sequential allocation of time slots, starting
from a user-specified time slot (defined under
START TS).
ALT Alternate allocation of time slots. This
selection means that starting from a specified
slot, defined under START TS, the time slot
allocation looks like this:
DATA NC DATA NC DATA, etc.
Default: USER
To assign individual time slots, select USER.
To let HCD-E1 assign the time slots
automatically in accordance with the
NUM OF TS parameter, select SEQ
(sequential allocation) or ALT (alternate
allocation).
If you have selected SEQ or ALT, you must
also set the starting time slot under
START TS.
NUM OF TS Selects the total number of
time slots being assigned.
NC, 0, 1, ..., 32 for UNFRAMED
1 to 32 for G732N
Default: NC
When working in UNFRAMED mode, this
parameter must be set to 32.
In ALT mode, the number of time slots
assigned depends on the value of START TS
and is 16 at maximum.
START TS Selects the starting time slot
for SEQ or ALT time slot
allocation
Any number in the range of 01 to 31, consistent with
the desired number of user time slots.
Default: 0
When working in UNFRAMED mode, this
parameter must be set to 0.
If you selected SEQ mode for G732N, make
sure that the sum of the START time slot
number and of the NUM OF TS parameter
does not exceed 31.
IDLE_CODE Selects the code transmitted to
fill idle (unused) time slots in
the E1 frames
The available selections are 00 to FF (hexadecimal)
Default: FF
