When I say "it's not working" I mean the following:
- The DSU led is steady green
- The ERROR led is flashing in red
- The ALARM led is steady red
Did loopback tests on both units with a straight through cable and they both
worked fine.
Performed a QRSS test on all DS0 with my T1 croosover cable and shows the
following: ES 0 BES 0 SES 0 SYNC *NO
I hope this is enough info...
