Application Scenario
Long-Range Wireless Phone Scenario 2

Private and Closed Cell Phone Network :

The user can deploy 3 LC-02/B Central Base in arange over 60~180Km. Dividing the range into 3 areas(say area A, B, and C); each area assigned a base (say Base A, B and C), each base applies a CO line (say line A, B, and C). With the manual ‘roaming’ feature, the user can access or be reached by different phone line service in different area of the range, and thus the phone service in the wide range is covered. The “roaming” among the 3 bases are set manually.

As the long range wireless telephone system (PABX/KTS) for Service Control Center: Free Cell Phone Charge

LC-02/B Central Base cascaded in Control Center forservice, patrol, emergencyor monitor...... CENTER!!

LC-02/H, LC-02/RC and LC-02/M as the client units of the system, can perform patrol and circular freely in the area; all the units can share the telephone service and facility; communicating with one another free of charge; or communicating through City phone line with limited charge.

Combination usage of PABX :Least Cost Regional Control Center for multi-area (Very limited phone charge)

Guide and proposal

Explanation of the proposal

	Communication Route for Dispatcher in Control Center to Control Center: CO line à area center PABX àdispatcher in the center

	Communication Route for Dispatcher in Control Center to service personnel in same area: LC-02/B à service personnel

	Communication Route for Dispatcher in Control Center to service personnel in different area: CO line à area center PABX à LC-02/B à service personnel

	Communication Route for service personnel to Control Center in same area: LC-02/B à dispatcher in the center

	Communication Route for service personnel to Control Center in different area: LC-02/B à PABX à CO line à areacenter PABX à dispatcherin area center

	Communication Route for service personnel to service personnel in same area: LC-02/B à service personnel

	Communication Route for service personnel to service personnel in different area: LC-02/B à PABX à CO line à areacenter PABX à LC-02/B à service personnel
