Description This command applies to E1 voice only.
In the R2 signaling A-bit and B-bit are used to transmit the valid information, and the
actual transmission signal has nothing to do with the setting value. C-bit and D-bit do
not transmit the valid information, and generally the set signal value is adopted as the
transmission signals. Therefore, for the R2 signaling, this command only makes sense
to C-bit and D-bit.
Using this command, you can adjust the values of C and D bits according to the line
signaling encoding standards in different countries. For example, in China, the values
of C and D bits of R2 signaling are fixed to 1 and 1 respectively. However, in most
other countries, the values of C and D bits are 0 and 1 respectively.
This command takes effect only after the mode zone-name {custom| standard}
command is configured , and is invalid after command mode custom configured,
namely the values of C and D will not be changed. With mode custom configured, all
signal values of R2 signaling are set manually. With mode zone-name custom
configured, some signals values are set as required, while most signal values comply
with the standard of the zone-name country.
