Personality PROM
• Enable CONFIRMED CALL for all GETCs except SCAT. If the GETC programmer does not allow for this, it is
accomplished by a hex edit of the personality per feature programming instructions 349A9945P1.
• CTIS is set to YES.
• Multisite System is set to YES.
• Individual channels are enabled for interconnect.
• Individual channels are enabled for External CIU (digital interconnect) only.
• Maximum Interconnect Calls is set to the appropriate number for the site.
• Recommended Special Call Hang Time is 30 seconds.

PI hang time and conversation limit should be set greater than those of the site so that the site GETC will generate
alerting tones to the radio before dropping a call. This setup provides the radio user the options of pushing the PTT button to
continue the call or simply allowing the call to be dropped due to expiration of the hang time or conversation limit.
