See Mounting the plinth on a wall for plinth installation instructions. Flexi Multiradio 10 BTS can only be installed as a right-hand installation because of optical cable routing reasons. Remove the two fixing studs from the front of the plinth or topmost casing. Remove the two screws at the bottom at the back of the casing. Fix the two plinth brackets at the back of the casing.

Align the plinth brackets with the remaining two fixing studs on the plinth and slide the module in place. Fix the plinth bracket screws. Check final steps on last graphic. At the front, fix the casing to the plinth or casing with screws.

Make sure a grounding cable is connected between the module front panel and plinth. It is designed to improve performance and is particularly useful for transmitting small amounts of payload data, such as VOIP, where the amount of payload may be smaller than the header.

Third and fourth generation wireless systems are being designed to support a wide range of services, including audio and video applications. One major problem with the IP based protocol architectures is the large overhead, which affects the limited bandwidth of wireless channels.

A low bit rate speech application can result in IP packets with a ratio of 30 bytes of payload to 60 bytes of overhead. To quote from RFC,Bandwidth is the most costly resource in cellular links.

Processing power is very cheap in comparison. Implementation or computational simplicity of a header compression scheme is therefore of less importance than its compression ratio and robustness. The overall reduction depends heavily on the size of the payload. The saving in overhead varies depending on the traffic models used. With that approach, advertised user service peak rates up to the cell peak rate can be momentarily supported in one cell.

The advertised user service rate will be, however, only a fraction of the cell peak rate. This also means that multiple users can be supported with that rate simultaneously.

With service differentiation, different maximum rates could be applied to different users. For example, premium users could be served with highest rates. If the number of users is low, transport costs could be reduced even further if the user service rate will be applied for dimensioning instead of the cell peak rate.

The practical maximum of air interface throughput could be achieved under such conditions, adding average capacity of the remaining cells to the one cell operating with peak rate. As illustrated in the above figure, this defines the recommended dimensioning range. Additional transport capacity beyond that range cannot be utilized realistically. In particular, the All-Peak concept will always lead to over-dimensioning, thus usually extra costs. However, if fiber is available at eNodeB sites, the incremental cost impact may be tolerable.

So, there will be cases where the operator requires that the transport sub-system shall be no bottleneck at all. The ToP clock is additionally filtered by collocated system clock to fulfill G.

Synchronizing PDH and 2. If eNodeB loses all sync sources, it switches to hold-over mode. The 2. In general, the LTE system is designed for low latency. This defines a design target with respect to LTE system performance rather than a hard limit.

In contrast to that, 3GPP Even though indicated in the table above otherwise, services using the reliable TCP transport 1 layer e. Transport Admission Control TAC is in charge of controlling admittance based on available resources on the transport network. For GBR traffic, information about the expected bit rate is available at this moment, but for non-GBR traffic, there is no knowledge and no control about the future user behavior. Non-GBR should be always suppressed there.

Configurations where eNodeB applications are bound to virtual addresses are typically used in scenarios where the transport link VLAN, IPsec tunnel shall be terminated with one IP address while application separation on L3 is also required.

In the simplest configuration, the eNodeB features a single IP address. Different interfaces belong to different IP subnets. It is required for on-path support to enable accurate phase synchronization. Similar to E-Line in that eNodeBs will not be able to communicate directly to each other traffic separation similar to point-to-point , but simpler to provision due to common point at the edge router.

Save the file on your PC. If you have earlier versions of the BTS Site Manager on your PC, you need to remove the installed versions before you can change the location.

It is not required to remove earlier versions of the BTS Site Manager when a new version is installed. If autoconnection is not enabled, the connection to the BTS must be done locally. Only HW and cabling need to be installed at the site. No personnel with telecom experience needs to be at the site to commission the BTS, as the integration of a newly installed BTS is fully automated. When the BTS is powered up, it will automatically check the BTS commissioning status, establish IP connectivity and retrieve operator certificate and trust anchors optional.

Autoconfiguration enabled This step is automatic if autoconnection is enabled. If autoconfiguration is not enabled, the connection to the BTS must be established remotely. The BTS autoconfiguration feature provides automatic commissioning and configuration of new or re-homed base stations from a remote network operation centre with minimal manual intervention. The automated configuration is initiated by the eNodeB auto configuration agent and controlled by the NetAct auto configuration application, which belongs to the overall NetAct SON coordinator application.

Prior to start of commissioning, there should be a visual check and inspection. For local connections, select Local. Information The default user name is Nemuadmin and the default password nemuuser. Using web interface at The FTM transport module provides a service to recover the transport module.

Information The progress of the operation is displayed in the Task Selection view. If you receive a message with the text Cannot establish secure connection, click the Accept button to connect to the BTS. One commissioning file is created that contains values for both BTS and transport.

Reconfiguration is only an option after initial commissioning has been completed. It allows you to update parameters from the existing configuration. This is not required for Manual or Reconfiguration. Site commissioning can only begin after all modules are initialized. If there are SW problems, the modules cannot initialize and the commissioning options will be grayed-out and not be selectable.

Location Enter the location of the element in the Location field maximum of 50 characters. Description Enter the description of the element in the Description field maximum of characters. The BTS ID has to be defined according to agreed value, which is usually determined at the network planning stage.

Do not assign arbitrary value for this parameter. If the value is changed it must be done in site commissioning. The Subnet Mask IP address can be 1. The other IP addresses can be 0. The leftmost 20 bits of the value correspond to the value of the eNodeB ID parameter lnBtsId and the 8 rightmost bits correspond to the value of the local cell resource ID lcrId. This parameter cannot be set by operator, it is calculated system internally and is only readable.

It name may either be detected by DHCP upon autoconnection or configured by the management system. CRL update This parameter specifies the period for executing a periodical interval update of the Certificate Revocation List. The value is given in hours. Value 0 means no periodical update. Ethernet CFM comprises three protocols that work together to help administrators debug Ethernet networks. These are: continuity check, link trace and loopback protocols.

They allow maintenance endpoints to detect loss of service connectivity amongst themselves. They also allow maintenance endpoints to discover other maintenance endpoints within a domain, and allow maintenance intermediate points to discover maintenance endpoints. They allow the transmitting node to discover vital connectivity data about the path. Link trace is similar in concept to UDP Traceroute.

Loopback indicates whether the destination is reachable or not; it does not allow hop-by-hop discovery of the path. One point performs test traffic generation and analysis. The other point must be able to send back the test traffic. The purpose of the measurement is to have an estimation of the quality and performance of the IP-based mobile backhaul for each QoS class independently, indicated by Diff Serv Code points.

The received packets need to be analyzed and used for statistics whether the responding partner is capable to generate a TWAMP Response message or whether it returns the sent message un- modified UDP echo server. Up to 10 simultaneous measurement sessions can be started on the eNodeB. The sessions can be used to get measurements on different QoS classes. Once started, the measurements are gathered forever or till the measurements are explicitly stopped.

The measurements are aggregated into PM counters that are uploaded every 15 minutes. Flash light ,pocket lamp or torch. Hammer Drill. Drill with screw driver.
