T-Server Upgrade 7.2 - 7.6 Nortel x.25 NCS2000/2100 (DMS-100) Connect Problem

[smarsolais]

Upgrading T-Server from 7.2 to 7.6

I'm getting a problem connecting to the switch when trying T-Server 7.6.0.13 and 7.6.0.9 Nortel NCS2000/2100 over x.25 switch link. 

I have simply created a new T-Server from 7.6 template in CME and I imported all options from a running T-Server 7.2 application. Theoritically, these options, I thought, would have been sufficient to at least connect to the switch regardless of new features available in the new version.

What is strange here is that I see that T-Server sends a DV-APPL-LOGON to the switch but I do not get any error back from the switch. I only get a timeout from the T-Server after 10 seconds waiting.

Moreover, I can see from my EICON card tool that when the attempt is made to logon to the switch that an x.25 session is opened through the link so I'm thinking this confirms the link parameters are fine.

If I stop the 7.6 versions and start over the 7.2 version then 7.2 will start fine which seems to indicate the switch is not the issue here.

The LEC software load of the DMS is 14.

Have you checked the TServer release notes and deployment guide? You jumped two major releases up, some options may be deprecated or removed. Also, I guess you have checked whether TServer 7.6 supports your switch version especially on a X.25 link, haven't you?

Hi there,

One check new option on Tserver 7.6 into release notes.
Second you might check your Switch option, different option have to be added. Because the way Genesys handle their call in 7.6 is very different from 7.2. That could explain why 7.2 works and 7.6 doesn't work.
