linemon examples

The following examples show how to use linemon to record and display specific trunk timeslots:

• Recording and displaying trunk timeslot 0 in T1 mode

• Recording trunk timeslot 40 in E1 mode

• Recording timeslot 0 in T1 mode using a specific board and specific monitors

For all linemon commands, the -n option can be ignored when both of the following are true:

• Default switching between trunk timeslots and MUX DSP timeslots is used on the CG board.

• The MUX DSP resource starts on DSP timeslot 0.

Recording and displaying trunk timeslot 0 in T1 mode

The following example records and displays trunk timeslot 0 using T1 mode (the default mode). The command shown here also works for an E1 trunk, if the monitored timeslot is less than 24.

Command

linemon –d 

Received data

Note: To ensure that linemon is recording an H.223 level 2 3G-324M call, verify that the received data contains E1 4D 00 00 00.

Recording trunk timeslot 40 in E1 mode

The following example records trunk timeslot 40 using E1 mode.

Command

linemon -l 40 -e

Received data

E1 CAS or PRI mode set (30 timeslots per trunk)
Monitoring timeslot 40 using DSP timeslots 144 (line.out) and 145 (line.in)
Making switch connections 16:40->17:144 (line.out) and 4:10->17:145 (line.in).
Recording of Line Out and Line In Started.

Recording timeslot 0 in T1 mode using a specific board and specific monitors

The following example records timeslot 0 on board 1 into monitor_ts0.out and monitor_ts0.in. It uses T1 mode (the default mode).

Command

linemon -b 1 -f monitor_ts0

Returned data

Monitoring timeslot 0 using DSP timeslots 144 (monitor_ts0.out) and 145 (monitor_ts0.in)
Making switch connections 16:0->17:144 (monitor_ts0.out) and 0:0->17:145 (monitor_ts0.in).
Recording of Line Out and Line In Started.
