This involves defining the setup rules for the synchronization sources used.
– Priority principle: • the order of priority numbers take precedence, followed by the channel numbers, in increasing order of appearance; • an order number must be single (one specific number per sub-assembly); • order number one is for the highest level of priority. Note: Two sources cannot be assigned the same order of priority (the «Apply» button is not available).
4.5.7 – X-Pol RBS 4.5.7.1 – Radio group screen On the right of the BS supervision screen are all the X-Pol RBSs associated with the It is possible to have up to eight Radio Links and seven Radio Groups. A Radio Group is composed of a maximum of two OTU, two ORU and 6 AMD/IBS boards. When a Radio Unit is active and unlocked, it is displayed through a yellow wave (going out for the OTU or going inside for the ORU) A green point means that there is not any alarm; red point means that the unit has some alarm.

4.5.8 – Redundancy Radio capability 4.5.8.1 – Principle Redundancy of the A7390 system corresponds to a 1+1 configuration and works in the "cold redundancy" mode. That means for one active entity, there is one stand-by entity and when the active entity has failed, the switch over to the stand-by entity provokes a temporary service cut. Redundancy applies to the management part (ANT board). 4.5.8.
We could create a new Radio Unit with other carrier (see § 4.5.7.3 – Screen Radio Unit Creation) The management of the second pair must be manager by a porteur different from the first pair. The second radio is supervisor with the other IBS. We can verification with the mouse on the radio managment It is necessary to position the mouse on the connection «Radio Manager Link» which we have in the screen.
4.6 – NT Supervision The system manages 100 NTs maximum per BS, with 31 NTs maximum per upstream for 28 MHz channelization and 15 NTs for 14 MHz.

4.7 – Radio supervision and parameters 4.7.1 – Radio configuration To access the supervision and parameters of the Radio link, click on the button shown here (BS screen button bar) The Radio Configuration screen is displayed and presents the radio characteristics. The screen displays as many "Radio link # ..." tabs as there are radio links in the system (8 maximum). Click on the arrow to select the bandwidth: 14/4 Us*3.
IF YOU WANT TO CREATE AN IP SERVICE ON AN NT, THE UPSTREAM USED BY THIS NT MUST BE CONFIGURED. CF. § 1.. 1. Define the channelization ckick on the button (14/4 Us*3.5 or 28/4 Us*7 MHz). 2. Define the downstream central frequency. 3. Define the upstream central frequency. 4. Define the frequency of X-Pol Tx (OTU). 5. Define the frequency of X-Pol Rx (ORU). 6. Define the Transmission Power dBm (+17 dBm) with the step of 1 dB. 7. Define the Rx gain dB (-40 dB) with the step of 1 dB. 8.
4.7.2 – Dynamic Traffic Configuration To access the configuration of the IP data traffic, click on the button shown here (BS Details screen button bar).
4.7.3 – On-demand Service management 4.7.3.1 – Introduction Radio resources management consists of distributing system resources, for each upstream and downstream channel of each radio link, according to customer services to be created. Customer services are available according to two types of radio traffic: dynamic (dynamic IP) and static (leased lines, static IP). The bit rate available for each radio channel is given by the bandwidth defined in the Radio Configuration screen (see § 4.7.
4.7.3.2 – Access to the radio pre-configuration To access on-demand services management and proceed with radio preconfiguration, click on the button shown here (in the button bar of the BS Details screen). Click on these tabs to configure the other channels Click on the arrow to enable Service of RRM.
– limit = 1 means no overbooking is allowed, – limit > 1 means it is possible to use more bandwidth than the physical one. – Upstream channels Call Admission Control Strategy: – Guaranteed MCR, allows the CAC to deny connection to an RRM port if the current sum of the connected RRM ports does not allow to accept the new RRM port without exceeding the dynamic resources. Degraded MCR allowed: – allows the CAC to accept every connection request.
Click on these tabs to display the radio resources of the other channels Meaning of the colors used to show the different parts of the bandwidth: The blue zone represents the bit rate allocated to leased lines (LL) type services. The yellow zone represents the bit rate allocated to static IP (IPstat) type services. The light grey zone represents the proportion of bit rate still available to create new static services (FreeS) without disturbing the dynamic zone.
