Page Local Line Loopback In this mode, data coming from the remote user equipment is looped back to it locally. This loopback is initiated by the managing computer connected to the local unit. Page Local Internal Loopback Activating Install Mode causes both sites to go into install mode, causing disruption in service for approximately fifteen seconds.

Page Chapter 10 Hub Site Synchronization When several units are collocated at a common hub site, interference may occur from one unit to another.
Like any other RF deployment, the wireless operation is highly dependent on factors such as available frequencies, the physical spacing between radios, other interfering radios, and whether WinLink or RADWIN units are installed.
This set- ting prevents the unit from causing interference. WinLink radios used as independent units do not require HSS hardware. The efficiency of the air interface will vary according to the product used Configure the unit from the Link Configuration Wizard according to the procedure described above. It synchronizes the trans- mission timing of multiple Hub-Sites to the same clock source thus eliminating mutual inter- ference. This is an impossible situation, if all the links must send and receive together.
It is further complicated by adding a third and further sites as shown. Notice that there are no Installation or Configuration wizards. Such configuration as is necessary is car- ried out using a modified version of Site Configuration for WinLink Page Figure Sitec 2.

WinLink offers a wide operat ing frequency range. A free frequency channel must be det ermined wit hin t he operat ing range, for opt imum performance.
As much det ail as possible should be obt ained about t he t wo designat ed ODU inst allat ion sit es and t he area bet ween t hem. Mark t he t wo designat ed inst allat ion sit es on a t opographic map of t he area. Measure t he dist ance bet ween t he sit es; check t hat it is wit hin t he specified range of t he equipment. On t he urban map, check for developed areas sit uat ed bet ween t he t wo inst allat ion sit es.
Pay at t ent ion t o t hese areas when performing t he physical sit e survey; t here may be t all buildings, RF t owers, or t ransmit t ers, which could cause int erference t o t he link.
Check t he area bet ween t he t wo sit es for obst ruct ions such as: High ground - hills or mount ains Lakes or large bodies of wat er. Wat er has a reflect ion effect on RF signals like a build- ing. This t ype of reflect ion causes t he received amplit ude t o be reduced.
