TN9400 Trunked Core Network
Why choose a TN9400 Trunked Core Network?
Flexible, cost-saving design
The TN9400 offers both P25 Phase 1 trunked and trunked simulcast operation, and supports P25 Phase 2 operation (with the TB9400). The trunked Analog Gateway (TAG) enables connection to legacy analog consoles. This provides a cost-effective infrastructure to meet your communication and operational needs now and in the future.
The TN9400 supports remote management for greater operational efficiency. Data transmission is supported over a standards based IP data pipe. Maximum site spacing with Linear Simulcast Modulation (LSM) (used with the TB9400).
P25 standards compliant
The TN9400 follows the P25 open standards compliance, and allows expansion via P25 open standard interfaces: CSSI and ISSI.
Dependable, secure reliability
The TN9400 offers high availability for ensured continuity of network operation in case of server failure. It also supports end-to-end encryption for secure transmissions.
Modes of operation
Phase 1: P25 Phase 1, P25 Phase 1 trunked simulcast, P25 Phase 1 trunked LSM
