DSP Status Minor Alarm 1

[RDECIT]

We have two units in a cluster that have exactly the same hardware. (3300 MXe, PRI and BRI cards installed)

Both are showing the same minor alarm.

DSP Status - Minor - Total 8 - Unavailable 12%

I have ran SHOW STATUS DSP and had this output:

Slot Number 1 Dsp 0 State: ACTIVE

Slot Number 5 Dsp 0 State: ACTIVE
Slot Number 5 Dsp 1 State: ACTIVE
Slot Number 5 Dsp 2 State: ACTIVE
Slot Number 5 Dsp 3 State: ACTIVE

Slot Number 7 Dsp 0 State: ACTIVE
Slot Number 7 Dsp 1 State: ACTIVE
Slot Number 7 Dsp 2 State: ACTIVE
Slot Number 7 Dsp 3 State: ACTIVE

I'm a bit lost now, as this shows them as active and I'm not experienced in DSP trouble shooting.

I'm not sure what the process was, but they should have made it clear that you need new DSP hardware for T.38.

One of the common misconceptions however is that you need it to act as a transient node. i.e.

Controller A -> SIP -> Controller B -> IP trunk -> Controller C

If a TDM fax machine off of A calls a TDM fax machine off of C, only A and C need T.38 licenses. In other words, it's only required where the fax is terminating onto the TDM plane.
