NOTE
When a call starts and ends, the MG shows the start time and the end time based on the polarity reversal
on the subscriber line. The billing terminal that supports the polarity reversal charging function, such as a
charging phone set, implements the polarity reversal charging function based on the start time and the end
time of a call.
7.2.2.7 (Optional) Configuring the Attributes of the Ringing Current
You can adjust the ringing tone volume by modifying the attributes of the ringing current.
Generally, the attributes of the ringing current need not be modified. You need to modify the
attributes of the ringing current according to the local standards only when the default ringing
current attributes do not meet the local standards.
Context
The attributes of the ringing current include the following two parameters:
l
Ringing current frequency: The higher the frequency is, the sharper the ringing tones are.
l
AC voltage amplitude: The greater the amplitude is, the louder the ringing tones are.
The default settings of the attributes of the ringing current are as follows:
l
Ringing current frequency: 25 Hz
l
AC voltage amplitude: 65 Vrms
Procedure
Step 1
In the global config mode, run the
voip
command to enter the VoIP mode.
Step 2
Run the
ring attribute set
command to configure the attributes of the ringing current according
to the data plan.
Step 3
Run the
display ring attribute
command to check whether the attributes of the ringing current
are the same as the planned data.
----End
Example
To set the ringing current frequency to 16 Hz (parameter value 0) and AC amplitude to 65 Vrms
(parameter value 1), do as follows:
huawei(config)#
voip
huawei(config-voip)#
ring attribute set frequency 0 acamplitude 1
huawei(config-voip)#
display ring attribute
ringing current frequency : 16Hz
ringing current acamplitute: 65Vrms
7.3 Configuring the VoIP ISDN BRA Service
This topic describes how to configure the VoIP ISDN BRA service on an IP network. When the
MA5616 uses the H.248 protocol, the device supports the access of the ISDN BRA user. ISDN
technology provides end-to-end (E2E) digital connection and supports multiple types of voice
and non-voice telecom services.
