3.4.6 Call Bumping (Bandwidth Release) for Voice Calls
Refer to Section 2.5.2 on page 34 for more information.
3.4.7 Bandwidth On Demand (BOD)
Refer to Section 2.5.3 on page 34 for more information.
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 65 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.
Table 17 Call Bumping AT commands

Table 18 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.
