Mobile Equipment Identifier (MEID) is a newly designed way to uniquely identify the mobile stations (MS) due to ESN exhaustion. In the Active Cell operating mode and IS-2000 system, the test set supports to test an MEID-equipped MS. The MEID related information either reported or retrieved during MS registration can be observed from the Mobile Reported Information screen. Also, you can establish a call between the test set and an MEID-equipped MS using the Public Long Code Mask (PLCM) determined by the specified PLCM Type .
The
MEID Support
setting is used to enable (
On
) or disable (
Off
) the test set to support of MEID and Enhanced PLCM tests for an MEID-equipped MS.
MEID Support
is set to

CALL:MS:REPorted:MEIDentifier:QUERy
command.

is set to

). The MEID-equipped MS only registers to the test set using pseudo-ESN which is derived from its MEID value. The pseudo-ESN reported from the MS is displayed on the Mobile Reported Information screen (see
ESN
).GPIB Command: CALL[:CELL]:MEIDentifier:SUPPort[:ENABle]
The
PLCM Type
determines how an MEID-equipped MS generates its public long code mask (PLCM).
