Tait TN9400

TN9400 Trunked Core Network


Tait P25 TN9400 trunked networks are IP-based digital systems specifically designed to provide P25 open standards compliant mission-critical communications over wide geographic areas. Our trunked networks are extremely resilient, with multiple levels of redundancy for reliable communications. For those seeking a single supplier for system supply and support, we can provide you with complete network maintenance and enhancement.

Why choose 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.

Operational efficiency
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.
