Description Use the mode command to configure the R2 signaling mode in a country or region.
Use the undo mode command to restore the default, as you would with the mode
itu-t default-standard
command.
This command applies to E1 voice only.
The implementation and parameters of R2 signaling vary in different countries.
Therefore, the mode needs to be adjusted to enable 3Com router to exchange R2
signaling with the switching devices of different countries or regions. According to
the configuration, the system automatically selects the appropriate subscriber-line
state, service type, metering signal, and the signal values of C and D bits, etc. At
present, it supports the modes in Brazil, Mexico, Argentina, India, New Zealand,
Thailand, Bengal, South Korea, Hongkong, Indonesia, as well as the countries and
regions that comply with ITU-T standards.
If the default-standard parameter is configured, then the system will initialize the
subscriber line status, service type, metering signal and C signaling bit and D signaling
bit and other parameters according to the national standards of the countries or
regions.
In the custom mode, you can configure the specific signaling exchange process and
signal values of R2 signaling, so as to adjust the R2 signaling in your country in a more
flexible way.
You can execute this command only when the register-enable off command
is configured.
