Evolved Trunking Core (eTC)

The Evolved Trunking Core (eTC) performs LTE mobility management, call control, resource allocation, and database management. It provides rich multi-media trunking services, such as mission critical push-to-talk (MCPTT), mission critical video (MCVIDEO), and mission critical data (MCDATA). Besides, the eTC enables intercommunication between the broadband and narrowband trunking communication systems. ATCA server supports more sites and more throughput, also supports single board expansion, local redundancy feature.


l  Supports abundant trunking services, including private call, group call, emergency call, short message, status message, positioning, etc.

l  Perfectly compatible with existing narrowband systems and enables unified services and management of the narrowband and broadband systems on one platform.

l  Supports load balancing, multi-level redundancy, mutual authentication, air interface encryption (AIE), virtual private network (VPN), Internet Protocol Security (IPsec), and end-to-end encryption (E2EE).

l  Flexible configuration enables smooth system upgrade and expansion.


l  Supports ATCA server featuring multi-protocol compliance, modular design, high performance, and large capacity.
