OpenVox B200E User Manual page 21

OpenVox B200E/BE200E has great adaptive ability that it
can be set as TE/NT mode automatically without any
parameters. When the driver module "wcb4xxp" loaded,
B200E/BE200E card can be configured for TE or NT mode individually
by jumpers. This port configuration is detected by the driver
automatically. You can see the messages when execute a command
below:
# dmesg|grep wcb4xxp
[root@localhost Dahdi]# dmesg|grep wcb4xxp
