3.4.6 Call Bumping (Bandwidth Release) for Voice Calls

Refer to Section 2.5.2 on page 34 for more information.

Table 18 Call Bumping AT commands

AT COMMANDS

DESCRIPTION

 

 

AT%M2=0

Disable bandwidth release for voice calls.

 

 

AT%M2=1

Enable bandwidth release for voice calls (default).

 

 

3.4.7 Bandwidth On Demand (BOD)

Refer to Section 2.5.3 on page 34 for more information.

Table 19 BOD AT commands

AT COMMANDS

DESCRIPTION

 

 

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.

 

 

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.

3.4.8 Incoming Call Screening

Use this function to set restrictions on incoming calls. Refer to Section 3.4.8 on page 64 for more information.

3.4.8.1 Data Call

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.
