Inverse Multiplexing for ATM
Table-22 ConfigGroupWorkMode Command (Encoding: 07H)
This should be the third command issued to configure a group, i.e., this command should follow ConfigGroupInterface command.
Command Parameters
Byte Sequence
Parameter Name
Default
Description
1
Group ID
NA
The physical group ID (0~7).
This is the same Group ID in ConfigGroupPara command.
2
Symmetry mode
NA
0: SCSO (Symmetrical Configuration and Symmetrical Operation);
1: SCAO (Symmetrical Configuration and Asymmetrical Operation);
2: ACAO (Asymmetrical Configuration and Asymmetrical Operation)
Note: Value exceeding 2 will be regarded as 0.
3
Stuff mode
1H
0: ITC (Independent Transmit Clock stuff insertion);
1: CTC (Common Transmit Clock stuff insertion)
If at least one of the links uses independent clock pin as its clock input, stuff mode can only be set as ITC.
If all the links within the group use common clock pin (i.e., TSCCK and RSCCK) as their clock input, stuff
mode can be set as either CTC or ITC.
Note: Wrong configuration will lead to wrong ICP cells.
4
Stuff adv mode
1H
0: Pre-notify the stuff event 1 frame ahead;
1: Pre-notify the stuff event 4 frames ahead.
ICP stuff cell indication. It tells the FE the distance (unit is IMA frame) between the current ICP cell and
the forthcoming stuff ICP cell.
Note: The upper 7 bits are Don’t Care.

0: OK;
1: Invalid parameter;
2: The physical group is not configurable;
Others: Internal error. The chip should be reset.
