What is c3gCdmaLastCallDisconnReason?

This read-only enumeration records why the modem's last CDMA call disconnected, with specific causes such as modemOffline(2), noService(4), abnormalCallEnd(5), or various base-station-initiated release reasons. An admin diagnosing intermittent cellular WAN drops relies heavily on this object, since it turns a vague "the connection dropped" into a specific cause like loss of coverage versus a base-station-initiated release. For example, a pattern of repeated noService(4) disconnect reasons would point the admin toward a coverage problem at the site, whereas repeated baseStatRelease-type reasons would point toward carrier-network-side call management.
