Field Installation Stages

• Equipment Setup

• Site Survey

• LBC – Link Budget Calculator

• Installation sequence

Equipment Setup

• 2 ODUs (if External > 2 Antennas +Mounting kit+ 2 N-Type cables)• 2 IDUs / PoEs• 2 IDU-ODU cables• 2 ODU Mounting kits• 2 Power supplies / Power cables• Grounding cables • Grounding lags• Installation Tools (should include also 13mm torque / Spanner + Tools for

installing the External Antenna)• Laptop (+Ethernet cables) • WinLink1000 Manager software

Site Survey – Important

• Must be carried out before starting installations.

• In order to verify the necessary environmental conditions for the successful operation of the link.

• In order to determine the best conditions for the WinLink installation, and to find a traffic-free operating frequency.

• In order to avoid problems and delays during the installation.

Site Survey - Stages

The Site Survey consists of three stages:

• Preliminary survey – Check the line of sight between the installation sites.

• Physical survey – On site preparation for installation.

• Radio Frequency (RF) survey (Recommended) - Using a spectrum analyzer, scan the installation area in order to identify RF interferences and to find a clear channels to be configured.

ODU / IDU Mounting Kit

LBC - Link Budget Calculator

• Reliable tool for calculating expected performance of a link• Can be used prior to installation to define and verify link parameters (expected RSS,

maximum range, number of E1s/T1s, etc.)• Enables verification of installation quality• Calculations consider “real world” factors• Link Budget Calculator is provided with any purchase of ODU and it is part of the

WinLink Manager

Link Budget Calculator

Installation Sequence

• Mount the ODU on the pole using the Mounting kit. • (In case of External ODU, mount the antenna and connect it to the ODU

using the N-Type cable).• Connect the ODU to the IDU using the IDU-ODU cable. • Ground the ODU.• Ground the IDU.• Connect the power to the IDU.• Perform the antennas alignment. • Install the RADWIN Manger on the laptop using the customer CD. • Run the Installation wizard using the WinLink1000 Manager.

Troubleshooting - Link

• Verify that both antennas have the same polarization (horizontal/vertical).• Check all the WinLink™ 1000-AIND cable connectors for faulty connections.• Verify that there are no obstacles in the Fresnel zone of the antenna path

such as large buildings, trees, etc.• Use a spectrum analyzer with suitable sensitivity to measure the signal at

the distance between the sites.• If nothing improves the receive power level, check the overall link.• Reduce the distance of the link-move the equipment from one site closer to

the other site-where it is possible to actually see the antennas with the naked eye.

• If you now get the expected receive signal level, you can assume that the equipment is operational, and the problem arises from interference between the sites.

User Types - Manager

There are three user types:• An Observer has read-only access to the link. An Observer can

monitor the link, generate reports, but may not change any link parameters.

• An Operator can install and configure the link.• An Installer can, in addition to functioning as an Operator, also

change the operating band. The latter function has legal ramifications, requiring familiarity with local regulations.

Adaptive Modulation

• Enables the system to change modulations automatically, depending on channel characteristics

• Enables the user to maximize the Ethernet throughput without degradation in the TDM service quality

• Supported Modulations and Air Rates:• BPSK (9Mbps)• QPSK (12Mbps, 18Mbps)• 16QAM (24Mbps, 36Mbps)• 64QAM (48Mbps, 54Mbps)

ACS (Automatic Channel Selection)

• Automatic selection of “best-quality” channel (based on PER) • Enhanced robustness and higher performance• ACS available in all WinLink™ 1000 products

Selectable Channel Bandwidth

• Channel Bandwidth selection menu 5MHz,10MHz or 20MHz • Default setting: 20MHz• More channels per band• Eases collocation deployments• Changing Channel Bandwidth sets the link back to Install Mode

TPC– Transmit Power Control

• Enables control of ODU transmitted power level • Available in all products

• Why use it?• Reduce co-location interference• Environmental issues

Advanced TDM Clocking

• Transparent (default)• LBT / Recovered or Recovered / LBT• Internal/Recovered or Recovered/Internal

Transparent/Transparent The clock at Site A regenerates the clock from Site B and vice versa.

Loop time/Recover The Site A port receive-clock is used as the transmit-clock for that port on both sides of the link.

Recover/Loop time The Site B port receive-clock is used as the transmit-clock for that port on both sides of the link.

Internal/Recover The Site A port uses its internal oscillator to generate its transmit clock while the Site B port regenerates the clock received at the Site A port.

Recover/Internal The Site B port uses its internal oscillator to generate its transmit clock while the Site A port regenerates the clock received at the Site B port.

Security & Encryption

• Enhanced air interface security for carriers and private networks• Encryption using AES 128-bit key• Initial encryption and authentication based on user-defined master key and password

AES - National Institute of Standards and Technology (NIST) Advanced Encryption Standard (AES).

AES128 - Takes uses less than 1% of the link capacity

Management Security

Three levels of password protected user authorization: Read – Enables SNMP get command Read/Write - Enables SNMP get and set command Traps – Enables SNMP Traps receiving

Enhanced Security

• In addition to existing security features such as:– Link Password (SSID)– AES 128 Encryption

• Release 1.790 & above have “Link Lock” feature:

Enhanced Security

• New ability to “lock” operation of specific ODU to the current remote ODU by MAC address

• Can be activated via the manager application in one direction or both • Prevents service/bandwidth theft even if the link password is known• “Lock” can be disabled only from the location it was activated

Ethernet Throughput Control

• Max Ethernet throughput can be controlled in steps of 64Kbps• Enables service pricing flexibility for service providers

VLAN management

• Enables separation of user traffic from NMS Traffic• All the protocols supported (ICMP, SNMP, TELNET and NTP)• Affects all types of management connections (local, network and over the air)

The Jitter Buffer

• By configuring the Jitter Buffer, the receiver jitter buffer for each site can be enlarged, thereby increase system resistance to interference

• By decreasing the jitter buffer we decrease the system delay. • The jitter buffer can be configured between 2.1 and 16.0 milliseconds

Telnet

• Supported for all WinLink 1000 products• Support local configuration and monitoring of the ODU on site (remote configuration

cannot be performed via Telnet)• Telnet login password = community strings

• Read allows display only• Read/write allows display and set commands
