Installation and Operation Manual 3.3.7.6 – Frequency Scan Frequency scan is a special function of SAGEM-LINK F Pilot used to measure receive spectrum around receive frequency, in order to identify radio interferers which could degrade the link sensitivity. The results are displayed graphically and are stored in the IDU flash memory for further consultation.
There are four possible configurations : 1+0, 1+1 HSB (Hot Standby), 1+1 SD (Space diversity) and 1+1 FD (Frequency Diversity). SAGEM-LINK F Pilot allows to modify the current configuration to a new one. This change is made without any ODU connected.
Do not switch on the equipment until the far end has been modified accordingly. A 1+1 configuration on one end and a 1+0 configuration on the other end will cause a software issue.

6.3 - Ethernet Features Description Two basic built-in applications are available : bridging and bandwidth allocation. The Ethernet interface allows to connect SAGEM LINK F to standard IEE 802.3 Ethernet devices. 6.3.1 - Ethernet Bridging When bridging is selected, the system learns automatically the MAC addresses of subscribers and forwards only those packets destined for the service side.
6.3.2.1 - Learning process : The SAGEM-LINK F is able to allocate bandwidth fairly by routing outgoing traffic through a set of queues and scheduling the release of frames, from each queue, in an equal and fair manner. To do this the Bandwidth Allocator (BA) must know which network devices on the Subscriber Network are communicating with the Service Network and it must assign queues to those network devices.
The Queue Recovery mechanism works as follows: 1. When a Private Queue is available the SAGEM LINK F polls the MAC Table every 6 seconds to find the device or VLAN with the most Service Network traffic that does not have a Queue assigned to it.
When the Ethernet input is not connected to a Ethernet device, there is an Ethernet alarm. This alarm can be disabled by checking the corresponding case. 6.5 - Ethernet Alarms 6.5.1 - Ethernet RJ45 LEDs Page 122/142 Issue 04 : July 2005 Reproduction and communication prohibited without the written permission of Sagem Communication...
When the green LED is lit, it indicates that the Ethernet cable is properly connected to an Ethernet device. When it flashes it indicates Ethernet activity. If it is not lit, it means that the cable is not connected, or that the Ethernet interface which is connected to the SAGEM-LINK F does not work.

• For other capacities, the T/R spacing must be equal to 126 MHz. SAGEM-LINK F 8 GHz radios working with this frequency plan, use diplexers designed to work with this particular frequency plan. An ODU can transmit one 28 MHz channel with 119 MHz T/R spacing or two 14 MHz channels with 128 MHz T/R spacing.

You can now use the Ethernet port for Pilot software connection. Notes : 1. If you have a SAGEM LINK F Network, with a proper configuration on all Network Management Interfaces (you have previously defined Ethernet IP address and route table addresses), you can run the Pilot of any IDU within the network, by entering the IP address on the Pilot command line.
Upgrading a 2x2/4x2 Mbit/s IDU Some low cost SAGEM LINK F versions are working only at two data rates : 2x2/4x2 Mbit/s. In order to extend the capacity to the full range 2x2/4x2/8x2/16x2 Mbit/s, it is necessary to enter a registration key.
