For proper operation of the site controller and iDEN system, the Smartjack
should be set up with the following options. The telco owns and maintains
the Smartjack, and should be involved in switch setting changes.
B8ZS Line Coding:
I
iDEN requires B8ZS line coding, while many non-iDEN applications use
AMI line coding. Improper selection results in "ones density" errors and
prevents proper site controller operation. Operators have reported
difficulties when the service provider provisions intermediate repeaters
with an "auto" function. If problems occur on the span, the intermediate
repeaters may automatically start switching between AMI and B8ZS,
searching for a signal. Some Smartjacks have automatic capability as well.
