11.4 AT*EALS Ericsson Request ALS Status
Used to request the MS to give ALS (Alternate Line Services) status.
The information is available on the SIM card. If ALS is active, the user
has two lines for voice calls. The line number or name tag for the line is
then indicated on the display.
11.5 AT*ECSP Ericsson Customer Service Profile
This command is used to read the customer service profile (CSP) from
the SIM. CSP is a list on the SIM, which indicates the services that are
user accessible. Each of the services has a related bit within the CSP.
The services are grouped into service groups, with a maximum of 8
services in a group. For each service group, a bit mask tells which
services are available (bit=1). Unused bits are set to 0.
