Use Silicon oil around O-Ring in order to avoid that the rubber is dried and water, sand, dust could enter into the waveguide.

Tighten the 4 screws in order crossed, first on one diagonal and after on the other. Use oil ant-seizing betweenthe threads of nuts and bolts because often lack of lubrication could cause metal parts seized together.

1- In the top of Antenna, remove the tape and plug the cap.

2- In the bottom of Antenna, remove the cap to drain outthe water or Humidity.

Adaptive Code Modulation setting

Radio capacity:

Is Only Ethernet

ACM enable: fixed bandwidthand variable modulation, at themaximum possible

ACM disable: fixed bandwidthand modulation

• Downshift (from 1024QAM to 4QAM): decrease Ethernet Capacity

• Upshift (from 4QAM to 1024QAM): increase Ethernet Capacity

For each modulation profile the Ethernet throughput can be adjusted.

Synchronisation Priority or QualityWeb LCT: Main Menu – Synchronisation

SETS is a hardware circuit that select the sourceinterface of synch in base at priority or it canswitch the source according with quality.

Free Running = missing source synch, an auto Internal synch is generated by itself (PLL).

Holdover = degrade of Synch, trying to recover.Locked = normal situation of STM1 synchronisation of status control

Ethernet switch

Take account the value of Max Packet Size [byte] when "802.1Qsetting" is set as DISABLE or FALLBACK the switch adds 4 Bytesfor internal S_Tag. With 802.1Q setting in SECURE (that means that

packet VID must be contained in Virtual LAN table list, otherwisethe packet is discarded), no internal TAGs are added.

Time to refresh theMAC address table foreach Lan interface

Routing basedon VLAN ID

802.11ad as 802.1Q adds 4 bytes in the header ofeach packet, the first 2 bytes concern of TagProtocol IDentifier. This EtherType is fixed0x9100 defines the new format "Vlan Stacking".

Ethernet Frame Fragmentation

QOS preserves High prioritytraffic during traffic congestionsto reduce Latency and Jitter

Latency is the time taken to process a DATA (Response time in/out)

Jitter is a statistical variation delay of packets caused by internalqueues on congested routers
