Howdy folks!

Got another question. When a trouble is refered to as a AIS-CI issue.. What does that include? wiring? equipment? or is it just a general alarm?.. Got a customer with that type of trouble and his asking what does it refer to?

The following CI Alarm are detected at DHEC245007 ATI
A. AIS-CI Detected
Z. AIS-CI Detected

Thanks..

Bob

Alarm Indication Signal - Customer Installation.

Do a search in this forum and you'll find all the info you need. Here's a clip:

"All T1 NIU's since 1998, and all HDSL units since 1999 support a feature called AIC-CI.

AIS-CI is a variant to the standard AIS alarm pattern. AIS-CI is sent into the network by NIU's & HDSL remote units upon detection of a loss of signal (LOS) from the attached CPE, or if the customer equipment is sending AIS. This tells the LEC technicians that the AIS "like" signal is not a network fault, but a fault that is originating from the CPE side of the DEMARC. ANSI T1.403 & ANSI T1.231 go into considerable detail with AIS & AIS-CI."
