Radio Digitali - Serie DRS/MW LINK
The DRS provides a cost-effective solution to high capacity data transmission requirements. Operating from 6 to 38 GHz, it features compact/easy to install IDU and ODU. The DRS provides user accessibility functions including Transmit Power, Receive Signal Level (RSL), and operating frequency. Additionally, it features enhanced software allowing capacity/configuration upgrade, downloadable field upgrades and an optional embedded SNMP agent for advanced network management capabilities, making it the ideal solution for networks operated by mobile service providers, internet service providers (ISP), utilities, public telephone operators, local governments, TV networks and corporate users. The DRS represent a new microwave architecture designed to address universal applications. The same ODU can be used for PDH, SDH and IP applications offering modulation schemes from QPSK up to 128QAM, and selectable channel BW of 3.5, 7, 14 and 28 MHz (from 10 to 56 Mhz in the WB option). The Software Defined Indoor Unit (SDIDU) offers a basic configuration, suitable for PDH application and can be upgraded with simple fw and plug-in hw modules for Super PDH, SDH, FE, GE and ASI options. This advanced technology platform is designed to provide the flexibility to customers for their current and future network needs. The ODU supports all applications within the same HW platform covering from QPSK up to 128 QAM with very low Phase Noise and superior reliability (high MTBF). The IDU supports both 1+0 and 1+1 protection and Ring architectures, it is provided in a chassis arrangement 1U 19 inch standard rack. The modem and power supply functions are supported using easily replaceable plug-in modules. An additional feature of the IDU is provision for a second plug-in modem / IF module to provide repeater or transit network configurations (East/West) or Capacity Doubling (East/East). DRS includes integrated Operations, Administration, Maintenance, and Provisioning (OAM&P) functionality and also Design features enabling simple commissioning for the radio network installation in the customer’s premises. Another highlight is the scalability and the capability to support a Ring architecture. This Ring or consecutive point radio architecture is self-healing in the event of an outage in the link and automatically re-routes data traffic, thereby ensuring the continuity of service to the end user. The overall architecture consists of a single 1U rack mount Indoor Unit (IDU) with a cable connecting to an Outdoor Unit (ODU) with an external antenna.
