atcomsystems.ca/forum Forums Other TDM Phone Systems Executone-Isoetec Telephones & Systems SL PORTS TRY AGAIN

IDS 648 with 3.0x09 software.
Fax machines through system on analog ports with DNIS through T1.
Every once in a while the sl port will die, no dt at all.
If I go to the port and assign a new extension # the port comes back and works fine.
Tried everything new sl card, new tri ps, moved cards to different slots, still ng.
If you take the corrupted extension and put it on a digital station port the phone comes up fine, back on the sl port DEAD.
Anybody know of any documented BUGS or a fix.
Rick

what else do you have on that Tri-power supply besides the SL board?
have you tried using an opxi instead?
TJ

Only things on tri ps is another sl card.
Too many faxes to start using those useless opxi boxes!!!!

Are you having trouble with 1 sli port or is this occuring to different ports?
Are there enough DTMF receivers?
Keys assigned properly to the sli ports?
Is the problem affecting inbound,outbound or both?

What card slot is the sli card in? I had something like this happen three weeks ago.

When you notice that the port goes dead - has it been off hook by the fax machine? In other words is the fax not disconnecting after a call and holding the line open, which will cause the IDS to eventually take the port out of service. What is the status of the ext. in the C-screen when you notice that the port is dead? Have you reset the port on the SLI card, before moving it?

The card is in cabinet 2 originally in last slot, then moved to third from last slot.
I have 15 fax machines in the system. It seems to happen on 5 machines. These five machines get the heaviest in and out traffic. They could work fine for up approximately three weeks, then the extension dies. No dt and no receiving. Reset on port does nothing, moving that extension to any sl port will kill the port. The only fix is to asssign a new extension number to the port until it dies again. three dtmf receivers between three cabinets.C screen shows nothing off hook.

Rick,
Please make sure that you do not have an 821 key on any of these ports. Go to H screen and L K 821
An IN/OUT key will get you every time. You may need to change the phone type in the A-K screen to 48k or DSS to view all of the available assignments. You may find that somehow this key is being toggled by someone who is not hitting the proper line access key when sending a fax. On another note, I've found that it's very helpful to add a dtmf/station combo card into the cabinet where you have any sli card. Some of the newer 12 port sli cards will accommodate a daughter board with (i think) four dtmf receivers. This will help lighten the load on the EVCM.

The 821 key is stupid, but these are the things that get us pulling our hair out.
If that doesn't work, I'll try to duplicate the problem here and fight with it.

Good luck,

The only things programmed on those stations is two LCR keys.
The SL cards in question do have piggyback cards on them.
The only thing I can think of is corrupt database. Handpack is something I would rather not do (300+ phones) if u know what I mean!!!!!!!
Thanks
Rick

Yes, handpacking sucks. I did one last week for a car service in the city. Gotta love those over-nighters.

I'll pm you with my cell number. This problem is very interesting to me.
