Connecting an ATA2 to CICS Loop 1

I am trying to isolate a connection problem using the Nortel Remote Software, and would like to rule out the quality of the circuit. It seems that most posts point to the PBX being oversensitive to line quality.

With CICS 4.1 w/IRAD 4 POTS x 16 Unit
Connect an ATA2 (say ext 223) to incoming Line003
Connect an ATA2 (ext 224) to a PC

In Theory the pc should be able to dial directly into the unit's IRAD feature by dialing extension 223.

Am I right to think this should produce a quality circuit?

Would there be any danger to the PBX (grounding, expected latency)?

Thanks
 
You don't call into an IRAD by intercomming an extension. Technically the IRAD doesn't have an extension at all.
You could call in and get say the Receptionist and have he/she/it do a Feature 817 to transfer you into the IRAD or you could have a single line that is assigned in phone system programming (Under IRAD programming) to the IRAD. That way you call that line directly from the remote computer and get directly in....

In the first post, I have IRAD set to pickup Line003 on the second ring.
I have had no success using the remote software. I am trying to figure out why.
Most of the posts in Tek-tips state either that the incoming line quality is to low to support a sustained connection with the PBX (something about the internal modem on the Nortel CICS is very sensitive) or that newer PC modems require a different set of initialization parameters (the old hayes "ATxxxxx" command codes).
I am trying to isolate if it is bad line quality by supplying the PBX Line003 with a perfect analog pots line.
Hence the use of an Nortel ATA2. The ATA2 has an intercomm extension of 223. But when you dial 223 from any other extension the analog side of the ATA2 actually rings the inbound Line003 on the PBX.
I figure that the short hop from the Analog adapter to the PBX has got to be the best quality line I can get. If that does not work then I must have a modem problem.

So my question is, will the Nortel ATA2 supply a perfect line (cadence, ring, battery, etc.)? Or is there a danger in doing this?

Ultimatly dialing the 223 extension from an inside line is just simulating and outside call.
 
Ah, I gotcha! Pretty clever. I haven't had a real problem calling into the IRADs on the CICS. Are you getting any specific error? IRAD not responding or something like that?

Can I ask you a few questions about the IRAD. I have supported a couple of CICS units over the years, but never used the IRAD feature. The client I am installing this for is 400+ miles away, so I thought it would save time and money.

I have put a ton of hours into making this unit's IRAD work; and can't believe that it hasn't worked. I consider my tech skills to be quite good/experienced (sounds conceeded, sorry). With that said, I need to weigh my options and decide if the remote management is worth it.

Do you use the Nortel Remote Software often?
If so what do you find most useful?
What are the limitations that you find?

Using Nortel ICS Remote tools 10 I consistently get a "Connected" status shortly followed by "RAD NOT RESPONDING", then the lines drop (usually the PC first, and the PBX about 60 seconds later).

Thank you so much for your help!!
 
bodifrench, I use the NRU usually many times a day, with very few connection problems.
I use a Hayes Accura 56K external modem the most so that I can watch the status lights. I use the default init. modem string with no problems.
I run NRU 10 on Win 2000 PRO, and WIN XP operating systems.
Have not yet upgraded to NRU 11 at this time.
I also run Norstar Manager 3.5 on the same systems.
I also run Norstar Manager 2.0 for old DR-5 systems on a WIN 98 machine.
To answer your questions, everything about NRU is very useful. Any programming you do locally can be done remotely, plus doing system backups is very important.


The only limitation I have found is that you cannot do cross connects or pull the power plug remotely.
Have you tried a different line at your end?
I have played around with an ATA to a RAD, and have had some success, but you could get a line hung since there is no DS signal from an ATA.
Have you tried an Operator transfer connection (F817)to see if that works for you? You could put an external RAD (temporary) on your CICS to help determine where the problem is.

I have had the same problem using internal modems. Try an external serial port modem.

Thanks MarvO,
Your last post got the rodent running on his wheel, that powered on the dim light in my head. Been trying to figure out why the simulated CO line (that is really connected to the ATA) would not drop/disconnect the line. A soon as I unplugged the line(not really good for the loop circuit) it would close the line.

You were right on the money about the ATA not generating the DS. Re-reading your post saved me some serious time. Thank you

All my CISCO ATA devices do generate DS Superv; so I took it for granted.
