Returns the command to its default setting of disabled.
no
Disables the PDSN/HA from treating IMSI and MIN as the same for identifying the PDSN/HA session.
Usage
Generally on an HA, the IMSI and MIN are treated as different and hence the RRQs with 1x and DO PDSNs
are processed as different sessions. You can use this feature to treat the IMSI and MIN with the matching
lower 10-digit as the same for identifying a session. The 10-digit MIN and the 15-digit IMSI are treated as
equivalent for the purpose of matching sessions if the lower 10 digits are the same. Any handoff from 1x to
DO or vice-versa is treated as the same session if the NAI and HoA also match. If the NAI and/or HoA do not
match, then the duplicate IMSI session detect and terminate feature is applicable.
