Accepting Call

Nx12 has accepted an incoming call and is waiting for the Telco switch to connect it. Or incom-

ing POTS call is pending – system is ’oﬀ-hook’ waiting for loop current.

Connected

All signaling is complete – the ISDN voice channel is available for use. Or a POTS line is

‘oﬀ-hook’ and loop current has been detected.

Desktop Director Status

is screen shows the status each Desktop Director. CH represents the channel number. As it

is possible to connect two Desktop Directors on the same port, there are two channels per port.

ese are numbered left to right as viewed form the rear of the unit, with two channels per port.

Each channel is assigned a Desktop Director number: DD notiﬁcation. us, by looking at the

Director number on its LCD (upper left corner), it possible to ﬁnd out exactly which port this

one is connected to. One of two messages will be displayed:

Activated

e Desktop Director is up and running on this channel.

Deactivated

No Desktop Director is connected to this channel, or if it is, it is not being recognized by the

Nx12.

Whenever a Desktop Director is activated, an Errors number is indicated. is corresponds to

the number of data packets lost since this Desktop Director was powered on. An occasional er-

ror is not cause for alarm, however if you see multiple errors accumulating over time, this should

be investigated. Possible causes are bad wiring, a bad port on the Nx12, or a defective Desktop

Director.

Note

If a Desktop Director Is connected to an external power supply, unplugging the connection

at the back of the Nx12 will not reset the error counter. A few errors (2-3) when powering

up the Nx12 is normal. If a Desktop Director Is ‘frozen’, the Nx12 will deactivate it. If this ever

happens, unplug the Desktop Director, then plug it back in.

On the Nx12 LCD, it is possible to investigate further by pressing the OK button. is will give

access to a detailed Diagnostics menu for each Director.

Select any available Desktop Director connection: DD connection

e Far end menu gives a detailed error status coming from the Desktop Director side. e

Near end menu gives a detailed error status coming from the Nx12 side.

Tip

If you suspect a malfunctioning Desktop Director, check its error status before calling Telos

support. Having these details at hand will allow us to best assist you.
