It doesn't really matter apparently.... different clocking, same clocking,
on the "silly" revisions it doesn't work anyhow.
Now it *may* be that there are revision D0's that do work, anyone ?
Kind regards,
Koen.

Is the clockrate on the lower connector the same as the clockrate on the
upper connector?
I know that some of the dual T1 cards are only able to provide clocking on
one of the two ports.

Subject: DCE Clocking on WIC-2T upper connector failing [bcc][faked-from]
Importance: Low
It's been a while since I wrote to groupstudy, so why not talk about
something I've noticed which was troubling me in the days I was cabling my
lab, and now I have some additional information that *might* help other
people....
The problem is with putting a DCE clock on the upper connector of a WIC-2T
interface. While putting a DCE clock on the lower connector (S0/0) works, it
is sometimes not possible to make it working on the upper (second) interface
(S0/1). The line protocol goes down after a few keepalives, and no pings can
pass regardless of the clocking rate put on the DCE side......
I solved this problem by cabling differently (no upper-to-upper connections
from WIC-2T to WIC-2T, but lower-to-upper connections with DCE on the lower
connector), or clocking DCE from a WIC-1T (which always seems to work).
Up until a few days ago, I was unable to find out what this would be
causing, was it a cisco platform problem or a WIC-2T problem.
I've done some tests with other revisions of the WIC-2T, and it appears that
this is a problem with certain revisions of the WIC-2T.
Unfortunately I only have HW revision 1.0, Board revision D0 in my home lab,
which seems to be having a problem with putting DCE on the upper connector.
(show diag)
WIC Slot 0:
Serial 2T (12in1)
Hardware revision 1.0 Board revision D0
However, trying with other versions, Revision A0 and C0 didn't experience
these clocking problems and worked perfectly..... In this case, older is
better ????
Maybe someone other has or will run across this issue, and this could help
them a little.
But I would still be interesting in hearing from others that have
experienced this problem, and be interested as well where they got the WIC's
from.......
Kind regards,
Koen.
