Indoor Unit (IDU)
The WL-2000 ® is the first radio system to incorporate front-loadable plug-ins to support diversified network requirements. The WL-2000 ® feature of auto-detecting the Plug-In type allows the end-users to seamlessly adapt to existing network requirements. Software-controlled "reduced capacity" utilizes Spectrum-on-Demand.
WL-2000 ® may scale from low capacity/low spectrum (such as 4*DS1/E1) to medium capacity / larger spectrum (such as DS3/E3) without the need of existing hardware modification. Furthermore, these changes are field upgradeable.
The Ethernet 10/100Base-T interface plug-in supports wireless bridge implementations. These implementations are ideally suited for Service Providers (ISP’s video-on-demand, MTU’s) and private networks. This plug-ins features two 10/100Base-T ports (Full Duplex) + 4*DS1 (E1) ports. The plug-Ins supports full transparent bridging. The PDH Plug-Ins may be used up to a maximum capacity of DS3+4*DS1 (E3+1E1).
Modular plug-in interfaces (6Mbps to 52 Mbps):
Wireless Bridge: 2*10/100Base-T+4*DS1
Wireless Bridge: 2*10/100Base-T+4*E1
PDH: DS3+16*DS1, E3+16*E1, 4*E1/8*E1
Entry-level SONET/SDH: STS-1/STM-0 (51.84 Mbps)
