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.

Note 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:

1. From the Main menu, choose Diagnostics.

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