T1/E1 Multiplexers
Simplify Your Network and Lower Costs
Intraplex® ACS-160 and ACS-260 Series Access Servers provide a single, high-reliability multiplexing platform that enables a wide range of mission-critical voice, data and audio applications for land mobile radio, microwave, transportation and government networking operations. Consequently, network managers can significantly reduce the need to add and manage additional, multivendor access equipment and circuits, while actually increasing performance and uptime.
The Intraplex Access Server features a common architecture and platform that can seamlessly support almost any combination of T1 or E1 transmission requirements over copper- and fiber-based services, as well as licensed microwave or spread spectrum radio links in point-to-point or drop-and-insert configurations. Application modules are available for voice; LAN, synchronous or asynchronous data; and high-fidelity audio. The product design allows application modules, network interface modules and power supplies to be shared and swapped among units for additional flexibility and savings. The Intraplex Access Server is available in a 3RU package (T1 models ACS-163, -165, -166 and E1 models ACS-263, -265, -266) that provides maximum application flexibility or a space-saving 1RU enclosure (T1 models ACS-167, -168, -169 and E1 models ACS-267, -268, -269).
Meeting Application and Industry Requirements
The Intraplex Access Server is in use daily, helping to meet industry and application needs in a variety of settings, including:
- Mobile radio — for transmission of two-way radio traffic between dispatch centers and transmitter sites
- State and municipal microwave networks — for reliable, integrated voice and data interconnect
- High-reliability federal government installations — for transport of specialized voice and data traffic
- LAN connectivity — for LAN extension and bridging
- Specialized audio — for transmission of linear uncompressed, as well as compressed, high-quality audio in a variety of formats including MPEG Layer 2 and 3, enhanced apt-X and J.41
Harris Intraplex professionals are available to provide assistance with network design, planning, application support and training.

Product Details
Unmatched Performance
The Intraplex Access Server outperforms other multiplexers by incorporating unique transmission techniques that maximize end-to-end circuit availability for real-time application traffic and services. As a result, these products can maintain connectivity even under network conditions and error rates that would cause other equipment to fail.
The product can be configured to provide power supply and common equipment hardware redundancy, with automatic switchover when any failure is detected. Complete automatic line protection switching options are also available. The T1 access server includes an integrated Channel Service Unit (CSU) that provides performance monitoring and electrical protection, allowing for direct connection to public networks.
Reduce Network Management Burden
Integrating transmission requirements on the Intraplex Access Server eliminates the need to configure, maintain and manage a proliferation of specialized equipment. The product’s Windows®-based graphical user interface and command line interface simplify local or remote configuration, system diagnostics and monitoring of performance and alarm information. Bandwidth can be allocated to the server’s built-in network management communications channel for remote monitoring, and a single Intraplex Access Server can be used as a gateway to collect, store, and forward network management information from other Intraplex Access Servers located in one network. Complete SNMP monitoring and control of the Intraplex Access Server is provided using an optional system control module.
Intraplex Channel Modules
In addition to standard voice and data modules, the Intraplex Access Server also supports specialized cards for transmission of variable rate data, non-standard fixed data rates, baseband encrypted voice signals, and broadcast-quality audio signals. SynchroCast3™ capability can also be added to the Intraplex Access Server to establish robust GPS-based simulcast land mobile radio systems.
