Action
Check T1/PRI cable
and change if neces-
sary. If cable is okay,
CO is not sending any
signal. Contact CO.
To locate the AIS
alarm, have the carrier
check the T1 network
element connected to
the T1 interface and
trace the problem.
Cable is broken. If there
are no frame slips, con-
tact CO. If frame slips
exist, set this board as
the master.
Possible span mis-con-
figuration (i.e., ESF is
selected but the actual
framing is SF, or vice
versa). Check span con-
figuration.
Location condition,
equipment problem.
- For excessive BPV,
check AMI/B8ZS set-
ting.
- For LCV/OOF, check
the MVIP bus master
setting.
OR
Have CO perform a line
test to check for a faulty
cable or line.
