Code Enable/Disable
I
To enable iDEN operators or telcos to activate ESF loopback of the
Smartjack, the option Code Enable / Disable must be on/enabled in some
Smartjacks. This option does not have any direct effect on the operation of
iDEN equipment. Yet Code Enable/ Disable does affect the ability of the
operator/service provider to diagnose network problems.
The site controller responds to the loopback code designated for Channel
Service Units, which is different than for the Smartjacks. The site
controller responds to ESF loopback codes on the FDL message channel,
or the in-band loopback code.
