CODAN Digital Microwave Radio

CODAN 8800 series - 7 GHz to 38 GHz

The CODAN 8800 series Digital Microwave Radio (DMR) provides 16 E1 (16 DS1), E3 (DS3), and 10/100BaseT ETHERNET transmission on an indoor unit and outdoor unit hardware platform. This is common across the entire frequency range from 7 GHz to 38 GHz.

This lightweight and rugged DMR delivers an exceptionally high grade of link performance particularly in difficult propagation conditions. In protected configurations, the CODAN 8800 offers 100% redundancy and uses advanced signal combining techniques to achieve exceptional link reliability.

The CODAN 8800 series digital microwave radios complies with the international standards for safety, spectrum emission and data transmission.

The product is software scalable and can be configured either locally or remotely. For large network roll-outs, installation can be undertaken by semi-skilled labour on site with commissioning by technical staff at a remote location.

All CODAN equipment is backed by a three year warranty and CODAN worldwide support network.

Key features

• Adaptive Reed-Solomon Forward Error Correction (FEC) provides a high grade of service through high immunity to multi-path reflections.
• Continuous Phase Modulation is robust and gives exceptional performance in high interference environments.
• Adaptive Receiver Intermediate Frequency Control substantially reduces adjacent channel rejection.
• Automatic Transmit Power Control (ATPC) and Remote Transmitter Power Control (RTPC) parameters are software controlled.
• CODAN MINET, the Windows® based element manager, controls and monitors the network configuration via the SNMP Network Management Interface. CODAN MINET can control data transmission capacity and firmware upgrades throughout the network.
• 100% equipment redundancy is featured in Hot Standby and Space Diversity configurations. Redundancy  switching  decisions are optimised for space diversity operation.

Data interfaces

CODAN network management

CODAN MINET is an intuitive, network management system with enhanced monitoring and diagnostic tools. It provides a simple graphical user interface to configure and manage local, remote and network radio terminals. Reporting of alarm status and statistical performance data further enhances CODAN MINET capability.

Because CODAN MINET is based on a standard SNMP platform it can be easily integrated with HP Open View.

The software enables proactive management of all links in a network from either single or multiple operator consoles running Microsoft Windows NT®, 98 or later.

Any Ethernet LAN attached management station running CODAN MINET can also be used to conveniently manage an IDU via the unit’s 10BaseT Ethernet management interface. SNMP management and cascading between IDU are standard features.

All radio links are easily controlled from the management station by either in-band or out-of-band signalling. IP Routers in each agent distribute the management information through the network to provide simultaneous management of all links from a single console. Inclusion of Trivial File Transfer Protocol (TFTP) capability enables remote site configuration and firmware upgrades.

With CODAN MINET definable alarm mapping capability, users can customize link and external alarm reporting criteria.

Redundant operation

The CODAN 8800 series digital microwave radio supports 100% redundancy in a 2RU solution with either single or dual antenna configurations.

Redundancy switching decisions are conditioned by parameters such as:

• Link Status (fault condition)
• User Definable Receive Signal Level
• BER performance

The controlling algorithm provides hitless switching between the main and standby receiver paths. Space and frequency diversity operation is also supported.

A single antenna configuration requires the installation of an RF splitter. The splitter is optionally available as either:

• an asymmetric split of 1.8 dB for the main branch and 6.5 dB split for the standby branch;
• a symmetrical 3 dB split for both main and standby branches.
