12.10. Indication of Network Service Availability
The STAT_LED pin status shows information on the network service availability and
Call status. In the UC864-E-AUTO / AWS-AUTO modules, the STAT_LED usually
needs an external transistor to drive an external LED. Because of the above, the
status indicated in the following table is reversed with respect to the pin status:
