Chapter 3 Using AT Commands

64

Note: The high threshold must be greater than the low threshold, otherwise, both of 

them will be reset to the defaults as shown in the table.

If you set %M2=1, %M3=0, %M4=0 and %M5=1, the BOD function will be disabled and the TA 

establishes fixed multilink PPP data call with both two B-channels and release bandwidth for 
voice calls.

Use this function to set restrictions on incoming calls. 

Refer to 

more information.

Use AT%Id=<phone number> [/<sub-address>] to configure a list of incoming 

call phone numbers (with sub-addresses), then use AT%P0=n to reject or accept the calls with 

the phone number in the list.

Table 18   Call Bumping AT commands

AT%M2=0

Disable bandwidth release for voice calls.

AT%M2=1

Enable bandwidth release for voice calls (default).

Table 19   BOD AT commands

AT%M3=n

n= 0-64 (Kbps), the default is 35.
Set the maximum threshold. The TA adds the second B-channel when traffic is 

above the threshold.

AT%M4=n

n= 0-64 (Kbps), the default is 25.
Set the minimum threshold. The TA drops the second B-channel when traffic is 

below the threshold.

AT%M5=n

n= 1-255. The unit is 5-second. The default is 24, that is, 2 minutes.
Set the time interval between calculating traffic load.
