Step 1 Change the SoftCo hookflash threshold.
-
If the user's POTS phone is connected directly to the SoftCo5816, run the config hookflashtime mpu lowerlimit <30-1000> upperlimit <30-1000> command to change such threshold.
-
If the user's POTS phone is connected to the SoftCo5816 user box, run the config hookflashtime subbox no <1-4> lowerlimit <30-1000> upperlimit <30-1000> command to change such threshold.
-
If the user's POTS phone is connected to the SoftCo9500 user box, run the config hookflashtime subbox slot <2-9> port <1-4> lowerlimit <30-1000> upperlimit <30-1000> command to change such threshold.
Step 2 Change the IAD hookflash threshold.
-
For the IAD101H and IAD102H, run the devasi parameter set 1 command to set the upper limit, and run the devasi parameter set 2 command to set the lower limit.
-
For the IAD104H, run the devasi parameter set 3 command to set the upper limit, and run the devasi parameter set 4 command to set the lower limit.
-
For the IAD1224, run the dev parameter set 1 command to set the upper limit, and run the dev parameter set 2 command to set the lower limit.
-
For the IAD208E(M) and IAD132E(T), run the devasi parameter set 3 command to set the upper limit, and run the devasi parameter set 4 command to set the lower limit.
Step 3 If the fault persists, contact Huawei technical support engineers.
