You should clue in immediately to the very first probme - Layer 1 status
deactivated. You've got a physical layer problem. Look for a cabling issue
to be occurring between your routers and the ISDN switch.
Traditionally, an NT1 is used to connect an S/T interface to the ISDN cloud
(the NT1 provides a U interface for the S/T interface of an ISDN capable
device). However... Optsys indicates that if you have a U interface on your
router, you require an NT1. This is contrary to the ISDN specs. This is the
excerpt of the ISDN faq Marc Russell referenced:
Q - My router has a U interface type. What do I need to connect to a
Simline2?
A - You need an external NT1
And that doesn't make any sense to me. If you've got a U interface, you
don't
need an NT1 - however again, this is contrary to the Optsys Slimline faq:
Q - My router has a U interface type. What do I need to connect to a
Simline2?
A - You need an external NT1
And that's completely backwards to the ISDN reference points I learned...
TE2 - TA
|
| TE1 - NT1 ISDN cloud NT1 - TA - TE
| | | | | |
R S/T U U S/T R
I can't recall this exactly offhand, but I recall seeing something saying
don't plug an S/T interface directly into a U interface because damage can
result. I think it's in Cisco's documentation for the router--check there
for
confirmation. If you hooked up things incorrectly, you may have damaged your
equipment.
Note that you want to use a straight-through cable between the NT1 and ISDN
simulator.
Hope this helps...
