# 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

Display Output
Monitoring timeslot 0 using DSP timeslots 144 (line.out) and 145 (line.in)
Making switch connections 16:0->17:144 (line.out) and 0:0->17:145 (line.in).

Repeat ...

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

l inemon -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.
