Aprisa SE Digital Microwave Radio
Summary
Compact high-performance access solution for low-
capacity linking applications. Robust transmission of Internet, voice and data services
over long distances and difficult terrain. Simple migration from legacy networks to IP and
broadband capabilities.
Overview
The Aprisa SE digital access radio is a standalone access solution for low-capacity linking applications up to 1200 Kbps. The optimized, compact design incorporates a customer interface card (CIC) available in several configurations including a mixture of fractional E1, Ethernet, analog voice and digital data circuits. The radio is very simply integrated and is configured on a laptop or PC using the supplied Aprisa Setup™ software and Aprisa View™, the network management system (NMS) for the management and monitoring from a central location of multiple Aprisa SE links.

Interfaces
We've taken some key decisions to ensure Aprisa SE can be swiftly integrated into your existing and future networks without the need for external third party multiplexer equipment. Aprisa provides a wide range of in-built interfaces to transport voice, data and Internet traffic.
Interface options available include:
- 2-Wire subscriber (PCM/ADPCM)
- 2-Wire exchange (PCM/ADPCM)
- 4-Wire E&M (PCM/ADPCM)
- Ethernet bridge 10/100Base-T (UTP)
- Fractional E1 – 2 Mbps G.703/4
- V.24/RS-232 low-speed async serial data
- High-speed sync serial data
Customer Interface Card
Different mixtures of these interfaces may be combined on a Customer Interface Card (CIC) to support different applications.

To manage distribution of the traffic capacity to of the interfaces, Aprisa SE has been designed with an embedded micro cross-connect switch. This enables traffic to be reconfigured as network demands change, and supports ‘drop and insert’ grooming of channels from E1 bearers.
Performance
The Aprisa product family has been designed with enhanced features to provide robust, reliable, ‘carrier-class’ transmission performance for long and challenging paths. Reed Solomon forward error correction (FEC) delivers exceptional data integrity while the multi-tap equalizers optimize Aprisa’s multi-path performance. Advanced digital filters provide optimum protection against adjacent channel interference, allowing you to maximize frequency reuse.
With frequency resources becoming limited and expensive we have maximized data throughput with support for 16, 32, 64 QAM and QPSK modulation.
Configuration and Management
Aprisa SE is simple to install and commission using the PC-based Aprisa Setup™ software. A full graphical user interface makes it easy to configure radio frequency, interface and cross-connect parameters and add site details. Full-range performance monitoring information is displayed to allow antenna alignment, link commissioning and ongoing monitoring without the need for external test equipment. The local-remote feature allows the whole link to be viewed and monitored at one time.
A comprehensive range of alarms is provided to aid link diagnosis. These alarms can also be used to trigger major and minor relay output events for external monitoring. Aprisa SE can be managed and monitored from remote locations across a wide area network, allowing technicians to diagnose faults and performance issues before going into the field.
Aprisa View™ is the Network Management System (NMS) developed by 4RF Communications for the management and monitoring from a central location of multiple Aprisa SE links. The Windows® based software is easy to use, runs on a standard PC or laptop, and operates on any IP-based management network. Aprisa View is quickly deployed into an existing network and may be purchased pre-installed on a Windows-based PC or laptop, or as software only for installation by the user.
Apresia SE Protected Radio Link
The Aprisa SE Protected Radio Link provides a dependable radio-backup system that secures equipment availability to increase network reliability. It has been engineered for mission-critical telecommunications (where link availability is paramount) and for remote or inaccessible installations that need to sustain traffic for long periods before equipment servicing is possible.
The protected radio terminal consists of two standard Aprisa SE terminals interconnected by an Aprisa™ MHSB Switch. The switch is housed in a 1U chassis, and is typically mounted between the Aprisa SE terminals. It is controlled by a CPU that monitors the condition of the Aprisa radios and responds to a preset combination of alarm conditions that could indicate a failure in the radio equipment.
Aprisa Setup, the PC-based configuration, monitoring and maintenance tool, is used to configure the terminals to work in MHSB mode. The Aprisa MHSB Switch requires no configuration.The protected terminals may also be integrated to allow switch events to be reported within the Aprisa View™ NMS software. Discrete alarm outputs are provided from the protection switch to indicate protected terminal health.
