HOT TIP!
If you suspect the SPIDs given you are wrong, or the basic line provisioning (configuration) is
incorrect, call the Telco and ask to speak to someone who can “log into the switch”. They will
probably need to have someone call you back. Only once you have this person on the line, and
they are logged into the switch, ask them to look at the SPIDs programmed there. Also get this
person’s fax number and send them the ISDN ordering information form the Appendix of this
manual.
Sometimes the information in the business office computer is wrong. By verifying what is
programmed into the actual switch you can save time.
We’ve included some useful diagnostic aids in the system to help you determine where a
problem is originating. A good starting point is the ISDN status, accessible on the LCD by
pressing the Status button:
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, information 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
Wait SPID has been sent to network (DMS Cust. And Natl I-1 only).
Network has not approved SPID (i.e. SPID is likely incorrect).
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.
