1+1 Redundancy Kits for 1 and 2 Antenna Configuration
WL-2000 ® supports Hot Standby redundancy with no single points of failure.
Redundancy is achieved by routing the tributaries and interfaces input lines via a passive Redundant Switching Unit (RSU). The switching logic is performed in the RSU. Switching decisions are made according to Hardware and Software failure indications (link status, RSL, BER, etc.) generated by each terminal. A defective IDU or ODU can be easily removed without affecting the operating link and replaced with no down time. The RSU is backup powered by either IDU. The RDK (Redundancy Kit) is used to complete a protected WL-2000 ® terminal.
The RDK-X2161-C-13-38-1ANT kit supports one antenna configuration, for all frequencies, with asymmetric split RF Coupler. The kit includes the RSU, Redundant Plug-in (RPI-X2161, E3+16E1 or DS3+16DS1) and the upper and lower interconnection assemblies used to interconnect the RSU with the two IDUs. The kit includes the ODU Protection Assembly (OPA), which includes the ODU-1+1 Mount, one RF directional coupler and one rigid waveguide.
Not included (per terminal side) are the 2 IDUs and 2 Plug-ins, 2 ODUs, 1 Antenna + mount, 2 coaxial cables and one flexible waveguide used to interconnect between the OPA and the selected antenna.
The RDK-X2161-2ANT kit supports two antenna configurations for all frequencies. The kit includes the RSU, Redundant Plug-in (RPI-X2161, E3+16E1 or DS3+16DS1) and the Upper and Lower interconnection assemblies used to interconnect the RSU with the two IDUs. Each of the two ODUs are individually connected to an antenna. It is possible to mount the ODUs directly to the antennas, or use a flexible waveguide (Requires Mount-1+0 to mount the ODU on the pole). Not included (per terminal side) are the 2 IDUs and 2 Plug-ins, 2 ODUs, 2 Antennas + mounts, and 2 coaxial cables.
