keep careful track so you know what you have eliminated. Step 6. Fix the problem.

A Final Thought…

Constantly apply sanity checks. More than three decades ago, the Firesign Theater put out an album called “Everything You Know is Wrong”. Use that as your guiding philosophy in trouble- shooting a Telos Two set-up. For example, just because you checked the Telco line last night and it was fine does not mean that it’s OK now.

At 3:00 AM when the problems seem intractable and you are ready to give up engineering, remember that the system has worked and will work. Never panic–you are smarter than it is.

6.4 Troubleshooting ISDN Problems

Status Screen for ISDN troubleshooting

This screen shows the status of the ISDN connection. You can determine if the line is connected and whether the line and the Telos TWOx12 are successfully configured. In addition, informa- tion about calls is displayed here. One of the following status words will be shown for each active ISDN channel:

Deactivated

No line connected, or connected to wrong jack on the TWOx12. OR, ETS 300 permits the Telco to put a line to sleep. Deactivated will be displayed when this occurs

SPID Pending

The SPID has been sent to network (DMS Cust. And Natl I-1 only). Network has not ap- proved SPID.

SPID Error

The SPID is incorrect or line is grossly misconfigured

Ready

The unit sees a live ISDN S interface (ie external NT1 is present or internal NT1 has completed startup). If the SPIDS are present, they have been sent and approved.
