Test utilities
●
setslot
A utility to assign timeslot for HDLC channel. Only useful for TDM/E1 port.
Usage: setslot IF DIR SLOT
IF := hdlcx
DIR := [-]tx/rx ('-' for remove)
SLOT := [0-127]
Example :
# setslot hdlc0 tx 0
TDM/E1:ch0: TS 0 => Chan 0
# setslot hdlc1 tx 1,2
TDM/E1:ch1: TS 1 => Chan 1
TDM/E1:ch1: TS 2 => Chan 1
# setslot hdlc0 rx 0,2-5
TDM/E1:ch0: RS 0 => Chan 0
TDM/E1:ch0: RS 2 => Chan 0
TDM/E1:ch0: RS 3 => Chan 0
TDM/E1:ch0: RS 4 => Chan 0
TDM/E1:ch0: RS 5 => Chan 0
# setslot hdlc1 -tx 1,2
TDM/E1:ch1: Remove Tx TS 1
TDM/E1:ch1: Remove Tx TS 2
# setslot hdlc0 -rx 2-4
TDM/E1:ch0: Remove Rx TS 2
TDM/E1:ch0: Remove Rx TS 3
TDM/E1:ch0: Remove Rx TS 4
●
sethdlc
A utility to set HDLC mode. See sethdlc README for detail information.
Example : # sethdlc hdlc0 hdlc
●
hdlctest
A utility to do HDLC transmitting and receiving test.
Usage: hdlctest (hdlcX | hdlcX:hdlcY) [number_of_packets [packet_size [test_patten]]]
It supports two port tests. If only one port is specified, the tool both transmits and
receives on this port. It two ports are specified, the tool transmits on the first ports and
try to receive on the second port.

List HDLC channels
The HDLC channels are just a network devices in Linux. Use ifconfig command to see them.
Example :
# ifconfig -a
