ODU grounding and connection of the cables to hybrid and antenna Fig. The lineup consists of the following steps: on site radio terminal installation user connections and ODU installation as described in the relevant chapters equipment switchon equipment configuration through PC software antenna alignment for maximum received RF signal level network element configuration check measurements.
Traffic Baseband - Tributary Used tributaries must be enabled on local and on remote equipment. Service channels Service Channels Service channels setting must be the same on local and on remote equipment: different settings of not used service channels, between local and remote equipments, cut the operation of those service channels properly set also. Purpose of antenna alignment is to maximize the RF received signal level.
The relationship between AGC voltage and received field is shown by Fig. The received field level has a tolerance of 4 dB in the full temperature range. A factory default address is assigned to each network element that must normally be reconfigurated on site following the network administrator rules. This has to be done via serial cable or Ethernet cable. Warning: the checks that follow require a good knowledge of the program use. The description of each menu and relevant windows are given by the program itself as help on line.
Run the program and perform the connection to equipment by choosing from menu Option the connection made via serial cable. Perform the login to the equipment by entering: Equipment IP address 3. Enter the required port addresses in the available communication ports. The relevant routing rules must be normally given by network administrator.
Station name and remote element table must be assigned following description of the contextual help online? Assign the address in accordance to the address of the remote element you want to reach. It is advisable to perform the following measurements to check the correct operation of the radio hop: transmitted power received power RF frequency BER measurement.
Perform the BER measurement and check that values comply with the requirements. Settings here below are intended to be done both into local and remote radio equipment. The software to be used depends on the equipment you have to configure. In the following chapters all configuration steps are shown using LCT. Please refer to Fig. The other ports should be disabled. The correct cable crossover arrangement must be selected too see Fig.
Enable LLF if needed only at the end of link line up. For Untagged traffic, connections are done with Lan per port selections. Referring to Fig. Possible selections of Ingress Filtering Check: 1 2 Disable For all pass configuration Disable Output policy for Tagged packets: Level 2 priority, if used, defined for all the ports for incoming packets already Tagged. Invoming Untagged packets at Lan-1 are sent into output part queue following this selection.
In this example packets are inserted into queue 0. All types of packets go into Default Priority Queue. Settings are done to transfer only Tagged traffic within some Vlans. We want that Vlan , , and 1, 2, 3 can pass into the radio link and all the other Tagged or Untagged packets should be blocked. Inside LCT, select tributary window see Fig. All the used ports must be enabled, so enable Lan1 and Internal Port, see Fig.
The other port should be disabled. The correct Cable crossover arrangement must be selected too. Vlan settings for Lan1 and Internal Port should be like in Fig. All Untagged packets are blocked at the incoming port and outgoing Tagged packets dont change. Vlan membership is described into Vlan Configuration Table. A port can be member of no one, one or more Vlans.
There are 4 queue at each output port. The decision about to which output queue to send a packet is defined into Ethernet switch window selections for Into Lan1 window select Priority In this example incoming tagged are tagged and it is necessary to transfer the packets with no change so they must exit from output ports tagged, see Fig. Incoming Untagged packets at Lan-1 are sent into output part queue following this selection. In this example 3 local port must communicate with corresponding remote ports.
All the ports share the same radio channel but traffic originated and directed to Lan1 should be kept separated from traffic from Lan2 and Lan3 and viceversa. Lan1 to Lan1 connection should transfer tagged packets with Vlan 1, , and untagged packets. Unspecified tagged packets must be stopped. Lan2 and Lan3 have the same requirements. All the used ports must be Enabled.
Untagged traffic transits only if the selection for Ingress Filtering Check is disabled at each input port and a separated Vlan for Untagged traffic is set up for each port. The correct Cable Crossover arrangement must be selected too.
Vlan , , are allowed to exit at Port1 with tags Tagged. Different default Tags allow to keep separate the traffic from Lan1, Lan2 and Lan3 exiting at Port 1. At the remote end the traffic is split and forwarded from Port1 to Lan1, Lan 2 and Lan3 without Tag to preserve the original format. The same settings should be done inside the remote equipment. Maintenance 1. Normal operating condition Rx level on both ODU match values given by hop calculation. Equipment view current alarms with alarms grouping ALC Log history area with alarm correlation.
AL: alarms. Investigation must be made on a possible condition of bad propagation. ATPC info. Link telemetry fail No link between Local and Remote station. Traffic is cut. Telemetry link is a connection between local and remote IDUs. Link ID. EOC is the channel involved in management communication.
If EOC radio link is active:. Management is cut no remote ALC Traffic is OK. If relative LOS is active. Revertive When a branch is declared preferential. The return to preferential branch.
