PDH DATA RADIO LINK

YTMW WaveLink Digital Microwave Radio System is an emerging wireless telecommunication Technologywhich combines high frequency microwavetechnology, digital modulation and demodulation technology, computer controland telecommunicationtechnology. It has been used widely in the aspects of post, electricity,academics, and variousenterprises, military and professional systems especially for connectingbetween base stations of mobilecommunication. As an approach of rapid connection, it could also been inemergency and urgent communicationwidely. It is fast to setup, and can be deployed with great ease during urgenttimes when the needfor communication is imminent. The E1 PTP DigitalMicrowaveRadios of YTMW could be operated in the frequency of 2GHz 15GHz andcould be customized according to customer need. The system is a multi-functionand multi-purpose total solution of voice which provides date transmission ratefrom 2 E1 to 17E1 alongwith Ethernet transmission for flexible deployment Applications The unique architecture of YTMWDMS makes it ideal for deployments in a variety of applications such as mobilenetwork backhaul applications and fixed services applications. Lower frequencycoverage provides the ability to cover long distances over difficult terrain,and higher frequencies are suited to short-distance urban deployments as afiber/cable alternative for backbone or access traffic. * MobileCommunication Network For 2G and 2.5G backhaul, YTMW PDH systems are usedby carriers to interconnect base transceiver stations (BTS), and high-capacityradios to interconnect base station controllers (BSC). For 3G backhaul, our low/medium-capacity PDHsystems interconnect UMTS mobile base stations (Nodes B). * FixedService Network YTMW DMS supports IP network, LAN and WAN,with integrated voice and data transmissions over the same microwave link. Atypical application would be for an enterprise with a branch office located atsome distance from the main premise.*Private Communication Network YTMW DMS is also used to providecommunications links for private networks. For companies requiring frequentcommunications into areas without extensive telecommunications infrastructureor in areas where the cost of local access is high, installing and maintaininga YTMW DMS can be very cost effective. * BackupCommunication Network Microwave radio networks do not suffer fromthe long periods of outrage which often occurs when a fiber optic cable is cut.YTMW DMS is a viable secure and reliable alternative to protect missioncritical communication services. *Broadcast Contribution/Distribution Network With the implementation of terrestrialdigital broadcast, YTMW DMS is an excellent alternative for carrying bothcontribution and distribution services. Whether the network is PDH or IP-based,YTMW DMS will provide reliable and high performance transmission of the DAB/DVBsignals. KeyFeatures and Highlights * Broadfrequency coverage (all ITU frequency bands, from VHF-15GHz) * E1, FastEthernet tributary interface options * DataCompatibility With field-replaceable plug-in modules forIP interfaces, PDH provides extremely cost-effective 100 Base-T transport, witha duplex throughput of up to 37 Mbps, to provide superior error performance forthe transport of IP data. *Powerful Configuration Options Configuration options for high availability1+1 hot standby, space and frequency diversity for protection of traffic overchallenging paths. Choice of standard or high power options, with AutomaticTransmit Power Control (ATPC). *Compact and split-mount architecture Lightweight and compact size simplifies siteacquisition and installation. Small footprint avoids complicated cabling, asone indoor unit is capable of supporting several outdoor units. * CostEffective Deployment and Maintenance Featuresdesigned to enhance ease of use for installation, commissioning andmaintenance, such as simple front-panel controls, advanced loopback options,SNMP Network Management, and performance monitoring to ITU-T Rec. G.821/826. lComplies with all relevant ITU-R, ITU-T, and ETSI standards
