Good afterrnoon,......
I had our switch technicians create some 4 wire (S/T) type interfaces off of
our campus switch to get into our CCIE practice lab. They are terminated on
a 66 block in another building. I verified them there, and wire-wrapped them
to a DSX panel that terminates in our lab.
I am using a 1003 router for my test device using a plain Jane config....
(Isdn switch-type basic-5ess.... no shut on interface..... deb isdn
q921...... sho isdn stat) just to verify the lines. Here is the problem:
When I got it to the lab building it wasn't working properly...... Sho isdn
stat initally showed Layer 1 active..... Layer 2 waiting to establish....but
after awhile Layer 1 goes to ErrorInd.......
debug shows TX> ...yadda-yadda...... but getting NO response (RX) from
switch..... VERY sure its not a wiring issue.......
My question is,... and I've tried in vain to find the answer on the
internet, is "What is the distance limitation on S/T type copper run?"
Thanks in
advance!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
