ATM SVCs/Signalling

Fri Mar 21 16:20:16 UTC 2003

Mark,

1. What manufacturer of the devices and what model are the edge and then 
the network device you are connecting to?

2. What version and revision of UNI (3.1,4.0) is your edge device using? 
 UNI 3.0 is PVC, UNI 3.1 is original SVC support, UNI 4.0, 4.1 if it is 
out yet is more advnaced SVC. PNNI 0 did not support SVC so
      that would need to be at least PNNI 1.0 as I remember.

3. What version of NNI / UNI are the Network devices using?

4. What error code return are you getting?

5. Are your NSAPI addresses statis or dynamic and do you have dynamic 
TEI registration set or are they statucally assigned.

If your NSAPI and TEI are dynamic and your keep alives are not set rigth 
perodically you will drop "unregister" the NSAPI / TEI amd it will have 
to be reregistered again and
during this time the "route" would be dropped.
