I'm hoping you guys can suggest something because after several calls to SCSI over the last few months I'm at the point of having to rip it out.
Setup is a DTU3 Plus with high gain antenna, Tecom V8. Signal strength of 19-22 depending on weather, fail point is supposedly 12.
There is no PSTN available onsite, very low activity at site it can be a couple of days between opens.
SCSI was selected as was only option available for a regional site that the clients monitoring centre supports.
The GSM fault output is regularly going into alarm and being stored in the Tecoms buffer. GPRS fault is also occasionally seen.
Of concern is several times multiple GSM fault alarms are being received at once ie 20+ as if it has been offline for a long time.
This is occurring about once a week at random times.
My understanding is the outputs go into alarm if signal strength drops below 12 or if it does not receive an ack from CMS on its 4hr poll.
According to the CMS the 4hr polls are being received at their end.
Originally the fault outputs where alarming every 4hrs at poll time until SCSI changed something to resolve this.
Their response on the continuing issues is "network failure's"
Interestingly I had the CMS check some of the other customers with same units and they could not find any with the fault outputs programmed.
Anyone had this sort of problem with this equipment and been able to resolve it?
