Description
Trunk Group
ID number of this ISDN trunk group. A valid number ranges
from 1 to 31. It should not overlap with existing FXO PSTN
trunk groups.
Trunk Ports
The
Trunk Ports
is the logical range of the sum of B and D
channels. Each physical ISDN port occupies three Trunk
Ports, two B and one D channels. User only needs to
specify the B channel number here, since D channel is
reserved in the 3
rd
trunk port for each physical ISDN port.
E.g. Assume there are four ISDN ports in the PBX and no
other FXO/FXS modules installed, then one can set each
pair of numbers here, like 1,2 but excluding 3,6,9,11.
)
If a four-port FXO/FXS module is also installed, then the
Trunk Ports here should be numbered from 5 to 16
instead of 1 to 12. Make sure to specify the indices of
ports correctly, or PBX will not start. One can refer to
the
POTS Setting
page before configuration.
