Tone Injection 6-1
Chapter 6
Diagnostics
This chapter describes the Vmux-2100 diagnostic functions, which include:
• Tone injection
• Loopbacks (local and remote)
• Ping utility.
6.1 Tone Injection
The test tone is a data sequence at a rate of 1 kHz. This data sequence is identical
to the data sequence that would have been generated if a 1 kHz signal having a
nominal level 0 dBm were applied to the input of the channel speech processor.
The tone should be received clearly by the corresponding subscriber connected to
the PBX at the nominal receive level. Vmux-2100 supports tone injection towards
the local side only (see Figure 6-1).
The tone injection is activated individually per timeslot. However, multiple tone
injections can be run at the same time. Vmux-2100 allows you to set the tone
injection timeout causing the tone relay to deactivate automatically after the
desired period of time.

Before performing tone injection, make sure that the timeslot to which you intend
to inject the tone belongs to the properly configured E1/T1 port.
To activate tone injection:

The Diagnostics menu appears (see Figure 6-2).
