Indoor Unit (IDU)
The WitLink-2000® is the first radio system to incorporate front-loadable plug-ins to support diversified network
requirements. The WitLink-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.
WitLink-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).

Outdoor Unit (ODU) and Antennas
The WitLink-2000® flexible ODU/antenna combination is available
in all frequencies within 7~38GHz range, with ETSI and FCC
approved versions. The radio frequency components of the ODU
are contained within a hermetically-sealed enclosure. The ODU
may be press fitted onto the antenna and can be mounted on a mast,
tower or rooftop. This flexible design allows the ODU to be
disconnected from the antenna without affecting antenna alignment,
and directly mounted to the antenna without the need for use of any
waveguides or adaptors. One coaxial cable is used to connect the
ODU to the IDU. Power is provided to the ODU via this single cable.
The compact, aesthetic WitLink-2000® ODU is capacity independent as well, resulting in quicker deployment
and redeployment, simplified logistics and reduced spare part requirements.

WitLink-2000 Technical Specifications Rev-02
1+1 Redundancy Kits for 1 and 2 Antenna Configuration
WitLink-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 WitLink-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.

WitView-EM: SNMP Element Manager
WitView-EM™ is an intuitive, pro-active element network management system with enhanced diagnostic
and performance monitoring tools. It provides open, reliable and user-friendly GUI-based SNMP management.
Based on a standard SNMP platform, WitView-EM™ can be integrated with HP OpenView™ or used as a stand-alone
management application. WitView-EM™ supports local and remote terminal configuration, status/alarm reporting,
traps, statistics (per G.826) and diagnostics. WitView-EM™ provides the SNMP tool to proactively manage
all links from a single operator console, over IP. WitView-EM™ runs on Microsoft Windows® 95/98/2000 or
NT stations. The embedded SNMP agent in each WitLink-2000® IDU implements standard IEFT/RFC MIB II Ethernet,
E1/DS1, E3/DS3 MIBs, and private WitLink-2000® MIB extensions that enable remote monitoring and control
of the entire link or complete network from a single point. An incorporated RIP Protocol enables simultaneous
management of all radio links. All radio links can be easily in-band or out-of-band controlled from the management
station. All system parameters are software configurable.
Trivial File Transfer Protocol (TFTP) enables remote software upgrading.
