In this case the system will behave normally as a 2 carrier system, but will NOT support diversity. When using diversity set-up (Standard configuration), the RF coaxial connection must be installed and RX-B input (6dB pre gain) must be set This configuration also applies to the 4 carrier configuration, where the carriers are defined as two 2 carrier systems. 2.6.4.2 RX-B setting (Diversity) in TetraOM: 24 Display setting 24+ Select RX-B input Cascaded (Standard setting) 24- Deselect RX-B input Cascaded NOTE: This must be configured in both BS421 2.6.4.3 3 And 4 carrier operation NOTE: Operation with 3 and 4 carriers with redundant BSC require a change to the HW of the BS421 and the SB421 (See the SB421 section for details) if the HW version stipulated on the serial number label is v1. HW version v2 and forth has the possibility to change the setting via the TetraOM program. This change is required to ensure correct BSC handover and synchronization of the carriers The change cannot be made in the field. The system must be ordered for 4 carrier operation or the units may be returned to DAMM for modifications. NOTE: For change in the field (trained staff only), please order a change kit from DAMM This kit includes a manual dealing with this issue and the necessary hardware, jumpers, screws, markings etc. For a 4 carrier system, 2 of the BS421 is marked “MASTER” and 2 are marked “SLAVE” One master and one slave are to be connected to each SB421, the master being TR1/TR3 and the slave TR2/TR4. NOTE: A GPS antenna should at least be connected to TR1 and TR3 2.6.4.4 Synchronization The TETRA Base Station TR's need to be time synchronized to operate correctly. Most important, all TR's in a radio cell shall be time synchronized to ensure correct timing for the mobiles, when switching from the control channel to a traffic channel on another TR. For a multi-cell systems, all radio cells are also recommended to be time synchronized to enable use of seamless handover (cell re-selection).](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-2.png)

Date DRAFT 1.01 2012-01-27 Damm Cellular Systems A/S, Denmark TetraFlex® 7.5 Manual - BS421 Configuration TetraFlex® 7.5 Manual 2-73 The Damm BS system has a flexible system to provide synchronization between individual Transceivers. Build-in GPS Receivers give absolute time synchronization to the radio cells. External Inputs can also be marked as Primary Sync. References. When a BS is Network locked, automatic frequency correction of the Master Oscillator (RX and TX carrier frequencies) is provided, and Seamless Handover to other Network Synchronized Cells is activated. The BS can be setup to run as either Sync Master 0 to 4 or Slave. The Masters shall preferably be provided with GPS antennas or an External Primary Sync source. The remaining BS's shall be setup as Slave and does not need a GPS antenna. The BS421 is provided with one External 1PPS (1 Pulse Per Second) output and two external 1PPS inputs. The Slaves shall receive external 1PPS inputs connected to Masters. In addition to the hardware 1PPS, sync messages are send every second on IP from the Masters to attached BS's. A Master will indicate Master Mode, if: 1) Synchronized to the internal GPS RX or 2) Synchronized to an External Input marked as Primary and indicating Master Mode The priority can be changed with OM command 72/MASTER/c (c = 0-4 or S) Master 0 priority: 1) Int.

The instruction is also valid only if the TMD412 is provided, as the TMD412 is identical to the TMA412 except for the additional Duplexer. The TMA is to be connected with the BS using 3 shielded cables with a maximum insertion loss of 8dB. The adjustment procedure requires the loss of all 3 feeders to be identical. The adjustment is done to adapt the TMA to the selected output power of the TR and to compensate the actual loss of the 3 feeders. The TMA including feeder loss and AI411 input attenuation is recommended to run with a pre-gain of 6dB. This has been chosen as a compromise between sensitivity and dynamic range. It is not recommended to operate a higher gain. Output power in analogue NMT/MPT mode is fixed to be twice the output power in Tetra mode. The following equivalent input levels at the TMA input from the RFTL are recommended: Mode RFTL level TMA input (+6dB) TR input Analogue High -105dBm -99dBm Tetra High -108dBm -102dBm Analogue Low (-10dB) -115dBm -109dBm Tetra Low (-10dB) -118dBm -112dBm Note that RFTL low level (-10dB) is not supported in the first versions of the TR411. 2.7.13.2 Tools and Equipment Operating the TetraOM System requires a PC to be connected to the BS, a screwdriver, and a short test cable.](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-15.png)

Any TR connected to the node can be used. o Make Local Blocking (01+) o Select test mode CW (02/- and 15/CW) o Check the TX output power to be set to the required value (13). o Check, the TMA pre-gain to be 6.0dB (72) o Key the transmitter (10+) and activate the RFTL (32+) o Display RSSI (R/21/0) o Turn the 3 attenuators on AI411 “GAIN A”, “GAIN-B” and RFTL “OUT” to maximum RSSI (minimum attenuation). Step 2: RFTL input level adjust This step adjusts the RFTL input attenuator to give a fixed level on the RFTL mixer independent of the selected output power: The attenuation shall be adjusted to the following: TR power (Tetra) TR power (Analogue) Attenuator 25W 50W 15dB 12W 25W 12dB 6W 12W 9dB 3W 6W 6dB 1.5W 3W 3dB o Turn RFTL input attenuator to minimum attenuation o Register the RSSI o Increase attenuation until the RSSI has decreased to the value from the table Step 3: RFTL output level adjust This step adjusts the RFTL output level at the BS TMA Test Connector to be correct, if the feeder loss is 8dB. o Remove the feeder on the Test connector on top of the rack. o Remove the feeder on the RX-A connector on top of the rack o Connect the test cable between the Test connector and the RX-A connector. o Adjust the RFTL out attenuator to give an RSSI of –47dBm on TR41x input. o Remove the test cable and re-connect the feeders again The –47dBm is related to the nominal test signal level of –105dBm at the TMA, with a coupling loss in the TMA in forward direction of 50dB and a feeder loss of 8dB. Step 4: Feeder loss compensation adjust This step adjusts the RFTL output attenuator and the RM input attenuators to compensate the feeder loss.](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-16.png)

If step 1 and 2 has been done correctly, the reading should be –105dBm, if the cable losses are 8dB. If the cable losses are less than 8dB, the input levels will be higher than –105dBm. The feeder loss will be: Feeder loss = 8-(105dBm+RSSI)/2 dB. o Adjust with AI411 RFTL “OUT” the RSSI TMA input reading exactly half the way down to –105dBm. For example if reading –100dBm then adjust to –102.5dBm. o Adjust the AI411 “GAIN A” to an RSSI input level on TMA-A input of –105dBm. o Adjust the AI411 “GAIN B” to an RSSI input level on TMA-B input of –105dBm.

To utilize SNMP you will need an SNMP Management Application. This application will gain access to the status of the TetraFlex network through the “SNMP Gateway”. This gateway could be a node in the TetraFlex network. In that case the PC which runs the SNMP Management Application will need to connect to this “SNMP gateway node” via the WAN connection. The SNMP gateway must have the SNMP extension agent installed and will need to have NM running. NM is responsible for updating all of the node status variables, whilst the SNMP agent will service the SNMP requests. The SNMP Management Application polls for the node status. Traps are not generated by the TetraFlex network. This is in accordance with recommendations found in the rfc1157. The SNMP agent packets can be downloaded from www.damm.dk extranet software download site. The SNMP agent packet consists of: SNMPAgent.dll This file is the actual SNMP extension agent. It works in correlation with the Windows SNMP service, which is already installed on the SB421 and BSC412. This extension agent is responsible for servicing SNMP requests. SNMP_install.vbs Script-file which will: Stop the Windows SNMP Service. Copy SNMPAgent.dll to SNMPAgent_.dll Import registry settings required to install SNMPAgent_.dll.

The DAMM TetraFlexApi.dll contains all the functionality to connect to the TetraFlex® Network and has a fully documented API to interface with the GUI. The dispatcher is delivered with a Multi Lingual Graphical User Interface. The DAMM dispatcher is generic and intended for standard use. In case the user wants additional features, this may be accomplished by programming their own application or obtaining a third party application using the delivered TetraFlexApi.dll and the TetraFlexApi.h file The TetraFlexApi.dll connects to an Application Gateway on a TetraFlex® node via a standard WAN IP connection. For API installation, please refer to the Application Gateway installation section. 2.9.2 Dispatcher Installation: The Dispatcher can only be installed outside the BSC, on a separate PC. It connects to the Application Gateway of the TetraFlex® through the WAN port. Prerequisite for this connection to be successful is that the WAN port of an Application GW node is physically connected to a network - and that the WAN port of the BSC/ Windows is configured with an IP address inside the same subnet as the PC on which the Dispatcher is going to reside. The dongle marked "API" must be inserted in the USB port of the Dispatcher PC before installing the Dispatcher. For the DAMM Dispatcher a dispatcher entry in the dongle must be present to allow the DAMM Dispatcher to start up. For a third party dispatcher, this entry is not relevant. When the BSC.exe is started, the Dispatcher installation files are automatically placed in the C:\Tetra\Share\Dispatcher directory on the nodes: By accessing the share on the node where the Application Gateway is setup from an external PC, the Dispatcher Setup.exe can be executed and the Dispatcher installation starts.](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-24.png)

![Doc. No. Rev. Date DRAFT 1.01 2012-01-27 Damm Cellular Systems A/S, Denmark TetraFlex® 7.5 Manual - Voice Gateway TetraFlex® 7.5 Manual 2-108 Let us assume two organizations, one with the prefix 101 and the other with prefix 102, both have fixed phones with local numbers 301 and 302 and TETRA mobiles with local numbers 401 and 402. The user numbers in the subscriber register for the mobiles will for organization 1 be set to 101401 and 101402 and for the second organization 102401 and 102402. When making any call from 101401 the base station will add the prefix 101 from the profile to the called number. When dialing 402 the complete number will then be 101402. This is positively checked for existence in the subscriber register after which the base station will initiate a call to the SSI for that particular mobile. When making a call from mobile 101401 to the number 301 the base station will add the prefix and get the number 101301. This does not exist in the subscriber register so instead the base station will make a call to the voice gateway indicated in the profile. When the system PABX receives the number 101301 it recognizes the prefix 101 as belonging to organization 1 and will route the call from the PABX with the prefix removed, effectively calling organizations 1’s phone 301. When a fixed phone in organization 1 calls the number 401 their PABX will recognize the number as a TETRA mobile and route it to the TETRA system PABX. The TETRA system PABX will add their prefix 101 to get the full number 101401 and call the TETRA gateway. The TETRA gateway will find the user number in the subscriber register and then create a call to the associated SSI. 2.11 VOICE GATEWAY Voice gateways can be activated on any node using the SIP protocol with Voice-over-IP (VoIP). The gateway is able to handle up to 31 simultaneous speech connections including conversion of speech from TETRA to A-law and vice versa, when running on the standard BSC412 platform and up to 15 simultaneous speech connections when running on a standard BSC421 platform. Up to 32 simultaneous speech connections are possible when a voice gateway is installed on a PC node. The gateway does not provide any PABX features but has the capability to connect via the SIP protocol to an external PABX/gateway where routing, number modification, and protocol conversion (to e.g. ISDN or H.323) are handled. The gateway is tested to support the recommended Innovaphone V6 software, running on an IP400 (No PABX feature), IP800 or IP2000. Products from other manufacturers can easily be applied as well. Each voice gateway is related to a node number. The SSI provided from the mobile station when making a call is not used in the system. Instead the system will always look in the calling mobiles profile and forward the call to the specified primary or alternate gateway node. This ensures predicted functionality independent of mobile programming. The TetraFlex® System supports the unique feature of adding a fixed prefix to all PSTN calls made of mobiles with a specific profile. This prefix can be used in the interconnected PABX for routing analyses, allowing a single TetraFlex® gateway to route calls to different organizations. The TetraFlex® voice gateway supports incoming and outgoing duplex calls. It also provides full support to allow any PSTN phone (fixed, IP, GSM, etc.) to establish call in connection to group calls. The caller will initially be prompted for ID and pin code before the group attachment. All group communication can then be monitored in the phone. PTT activation can be done by a combination of key pressure and VOX (Voice Operated Transmit). The voice gateway automatically makes SIP registration to the PABX. In case the redundant BSC takes over it will automatically re-register with the same name and its new IP Address giving full gateway hardware redundancy. In addition an alternate voice gateway can be established and defined in the subscriber register.](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-38.png)

MSPCSerial PEI SwMI PCWanSubnet 1 Subnet 2 The TetraFlex® System supports dynamic multi slot packet mode where Packet Data gateway/servers can be activated at any node supporting standard IP communication between TETRA Mobiles and attached units like laptops, application servers, workstations, FTP servers, WAP servers, etc. anywhere within the IP network/Internet. Fixed IP addresses are allocated for the mobiles in the subscriber register allowing direct access to mobiles from different applications. Computers connected to the mobile have to be set to DHCP and automatically the system will provide them with an IP address, mask, DNS server, etc. The DNS server address is configured in the profile for the mobiles allowing mobiles to use their company DNS Server. By default the TetraFlex® Packet Data gateway automatically announces itself to the connected IP segment with the RIPv2 protocol. The main router/default IP gateway therefore has to have RIPv2 activated as it ensures automatic rerouting to the redundant BSC when it takes over. It is possible to set up two redundant PD gateways/servers in the mobiles profile. Note that the access to a packed data gateway is not needed for making IP communication between two mobiles as mobile to mobile packet data service always will be available. The TetraFlex® System has full support for multi slot PD giving an approximate throughputs from 3.5 to 14 Kbit/sec depending on the number of slots used. If possible the system will automatically assign 4 data slots at startup and then preempt data slots when necessary to assign slots for speech. Each data slot can be shared by two users making it possible to have a maximum of 8 packet data sessions running simultaneous. In case slots assigned for speech is available the packet data gateway will monitor timeslots every 5 seconds and reassign these for data transfer. 2.12.1 PD GW configuration](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-45.png)

The TetraFlex® system incorporates a Base Station Controller, referred to in this document as the BSC For a complete list of TetraOM commands see the TetraOM help files manual. Several methods of communication are available depending on the actual need and tasks to be done. Outdoor units (SB421/BS421) must be addressed by their IP address : Default IP for TR #1 is 172.16.1.11, for TR #2 it is 172.16.1.012 and so on Default IP for BSC #1 is 172.16.1.10, for BSC #2 (redundant BSC) 172.16.1.19 E.g.

To activate the HDLC bus UART, use TetraOM command AU+. If for some reasons the HDLC cannot be activated use AU/FORCED first. For onsite situations, a CRT, keyboard, and mouse can be connected directly to the BSC with standard extension cables. This also allows monitoring of the Windows booting, modification of the BIOS CMOS set-up, and makes it possible to alter the IP address when lost. When a TCP/IP connection is available, file transfer to and from the BSC is possible and may be used for backup, restore and software upgrade. 2.14.2 Power supply addressing outdoor (SB421) The internal Power supply in the SB421 can be addressed with the OM command: AP When succeed, the response from the PS is Address: AP [PS421] Note: The Power Supply can only be addressed when the SB421 IP address is selected in the connection list. 2.14.3 TR421, Combiner, Power supply addressing indoor (BS4xx) To get access to these units the IP address for the BSC must be used and Port 42024 as shown in the connection list below:](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-63.png)

Commands without parameters are display-only commands and will not make any changes. Therefore, it is possible to "page through" the commands to find the right one without any risk to change vital parameters. The commands are divided into groups, covering the different functions in the TR. For example, all the TR commands are in the 10 to 19 group. If the first two characters are not representing a valid number in the 00 to 99 range, an error message will be displayed: Invalid TR412 command This is however not the case if the first character is a +, which are reserved for commands to the test box. In this case no response will be sent. If an unimplemented TR command is called, the following response is displayed: Unimplemented command 2.14.3.1.2 Commands OM commands organization: M xx - Main BSC OM Commands F xx - Base Station Controller (BSC) OM Commands S xx - Base Station Switch (BSS) OM Commands H xx - Base Station (BS) OM Commands (only for BS41x) xx - OM Commands without a letter in front is used for TR, PS or TCC 2.14.3.1.3 Running commands](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-64.png)

PS, Combiner. C/”OM command” can be used to view the messages from the message queue. Example: R/07/S (Show the actual time date and century seconds) C/63/N (Shows the GPS data stream from a BS421) 2.14.3.1.4 Simultaneous commands From the TetraOM terminal window, it is possible to combine several TetraOM commands using the “|” (Pipe symbol). Example: 00|03/A (shows software version and alarm flag list) 2.14.3.1.5 Local blocking mode After power-on, the TR always starts in normal operating mode. If a given command requires local blocking, it is shown in the help area for the command. Commands that require local blocking are not available during normal operation for operator interference. If a protected command is called, the following response is displayed: Local blocking necessary Only commands with a parameter are protected. After activation of local blocking (01+), all commands except factory configuration commands are available. 2.14.3.2 Parameters Two types of parameters are used. Generally + is used as parameter to turn on, enable or step up and - is used as parameter to turn off, disable or step down. E.g. 11+ (turn power supply on) 11- (turn power supply off For more complex functions, a / is used as separator after the command no. followed by the necessary no. of characters for the actual function. E.g. 13/27 (set output power to 27dBm) If the parameter is not valid for the actual command, the following response is displayed: Invalid parameter](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-65.png)

In fact it is not in relation to changes introduced in 7.40 that the routers have been mandatory. In fact the nature of multicast – when connected over switched networks (layer 2) can make problems with broadcast like behavior of the traffic. Meaning that a network which is shared with other users may be flooded with traffic from TetraFlex nodes While saying that routers are mandatory – it is also a fact, that the rendezvous point (RP) router is mandatory. It may lead to the misconception that RP is single point of failure. In the basic configuration of the router network this might be correct – as the RP is sitting as hub for all other routers, i.e. all traffic passes here. However – there are router techniques available – making it possible to introduce load sharing and redundancy setup for RP’s. Recommendations for this are under preparation. Cisco acronyms for this are MSDP (multicast source discovery protocol) and Anycast RP. 2.16.2 Network layout principle As opposed to the virtual network between the TetraFlex® sites – which in its nature is a mesh network, the routers connecting the sites are connected in a star type network. The connections through the internet, which the routers use as their backbone, are all radiating like spokes in a wheel from one router that is announced as the rendezvous point. The routers then facilitate mesh type communication around the network, through routing tables built inside the network. In reality the multisite Tetra network from Damm Cellular Systems A/S is two or more release 7 TetraFlex® nodes – working together through an IP network. All parties are equal and no node is single point of failure. The subscriber relevant information is contained in two registers. Inside the network, these registers are distributed and present on all nodes at all times. The distribution of the registers is done through multicast routing in the connecting router network. With respect to the registers and housekeeping of the same – a node is pointed out to contain the master mode register. This node keeps track of register checksums on all nodes in the network. In case of checksum mismatch on one or more nodes, the master register will initiate a download and overwrite of the relevant register(s).](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-81.png)

A 4-port switch module (HWIC-4ESW) is available from Cisco. 2.16.4 IP addressing schemes IP addressing recommendation is based upon a 172.16.x.x address. Inside a given node – the 4th octet of the address is assigned as the host address: .10 and .19 for BSC1 and 2. .11, .12, .13 and .14 for the BS421’s. The 3rd octet is reflecting the node number. For IP interconnection via routers, the subnet mask is set to 255.255.255.0 or /24. For IP interconnection via switched network, the subnet mask is set to 255.255.0.0 or /16. If changing these masks – remember to change also in the DHCP server on outdoor type TetraFlex®. All communication between the nodes in the multisite network is based purely upon IP. The network must provide both unicast routing and multicast routing. Group calls and register replication uses multicast communication and full duplex calls between two mobiles or to external PSTN via SIP also uses multicast although in nature being point to point In TetraOM connection to the BSC – use the command S71 to display the relevant settings in regards to multicast networking. 224.239.016.000/28 is the default multicast address segment in use by the system for register replication and for signaling of call activity between BSCs in the TetraFlex® network. The address can be changed to meet special requirements. 224.238.016.000/28 results in a address of 224.239.16.1 for exchange of control packets between BSCs and for call signaling. Further an address of 224.239.16.3 is created – which is used for multicast traffic relating to discreet listening. 224.239.16.4 is the multicast address used for replicating the subscriber register 224.239.017.001 is the default multicast address in use for log server signaling. The address can be changed to meet special requirements, amongst others allowing for more than one log server. 225.000.000.000 is the so called CMoIP base address. CMoIP is the actual communication data stream. The address can be changed to meet special requirements. It is possible to change the two first octets of the address – whereas the two last octets are assigned automatically by the system. This base address describes in the given example an address range of 225.000.000.000 to 225.000.254.255. The CMoIP address is assigned to calls in the TetraFlex system and signaled to all other BSCs through the signaling group 224.239.16.1. The assignment of CMoIP address is done by the originating BSC and is done as incremental and round robin – meaning start at 225.0.0.0, next call 225.0.0.1, and next 225.0.0.2 until 225.0.254.255. Then system restarts numbering from 225.0.0.0. When a BSC starts up – it automatically involves the IGMP (Internet Group Management Protocol) and send off an “IGMP join” message to the network on the LAN. This “join” is sent](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-83.png)

The joining of the two groups will be active for as long as the BSC is active. When a call is initiated, it is signaled to all other BSC on multicast group .1. All other active BSC will receive this message. The signaling makes it possible for all the BSC’s to decide whether a given call is relevant to any terminal under its control. At same time – the originating BSC will assign a CMoIP address to the actual call and send an IGMP join message to the network to create the group in the routers. The address of this given group is contained in the signaling. Any BSC that has interest in receiving the packets from the CMoIP group will make an IGMP join on the CMoIP address. After the call activity is terminated – the given CMoIP group will be taken down by IGMP disjoin messages. The above mechanism is used both for group calls, full duplex calls, semi duplex calls and voice gateway calls.

Date DRAFT 1.01 2012-01-27 Damm Cellular Systems A/S, Denmark TetraFlex® 7.5 Manual - IP Backbone network layout and configuration TetraFlex® 7.5 Manual 2-157 Activity in the TetraFlex® nodes may induce traffic load on the connecting IP backbone network. This load varies, depending on the type of activity. 2.16.5.1 Group call: The communication scheme in use for group calls is point to multipoint. As the call type by nature is one too many – this is comparable to point to multipoint. The BSC with PTT’ing terminal will generate a stream of data packets. All nodes with members of the same group as the PTT radio will receive the data stream and present it on their air interface. The CMoIP stream will be at approximately 12 Kbit/s on the LAN port of the SB421. After having passed the router the resulting bandwidth will be 22 Kbit/s. The difference is relating to the fact that IPSec and GRE both will add protocol overhead to the stream. At the rendezvous point – the data stream will be replicated as applicable – resulting in one or more data streams leaving the rendezvous router (RP). Amount of outgoing streams from RP is decided through the IGMP mechanism. To summarize: at the RP router – there will be one incoming voice stream with bandwidth 22 Kbit/s per active group call (from the PTT BSC). The amount of outgoing bandwidth is decided through IGMP and is 22 Kbit/s per receiving BSC. The incoming/outgoing pattern will change according to which node has the PTT activity 2.16.5.2 Full duplex: Full duplex call is point to point. In TetraFlex® it is still transported as multicast. The full duplex call will generate a bidirectional voice packet stream. So at each BSC relating to the call there will be 12 Kbit/s outgoing and ingoing. Thus a full duplex call will load the RP with 2*22 Kbit/s in both ingoing and outgoing direction. 2.16.5.3 Half duplex: Half duplex call is point to point. In TetraFlex® it is still transported as multicast. Half duplex call will generate a voice packet stream where the direction of packets is decided by the PTT BSC. So a half duplex call will load the RP with 22 Kbit/s ingoing and outgoing. 2.16.5.4 Replication: The replication of subscribers is done via the signaling group and the replication group. All active BSCs are listening to the signaling group. When a master register decides to replicate because of checksum errors or a forced download of subscriber details is initiated through TetraOM, it results in a data stream from the BSC with the master register to the RP and outgoing stream from the RP as many as there are BSC’s with faulty slave registers. The replication is done at a rate of 130 Kbit/s on the LAN – resulting in 158 Kbit/s on the “outside” port of router. So in a scenario with 10 nodes (1 master register and 9 slaves) this will result in RP load of 1*158 Kbit/s incoming and 1*158 Kbit/s outgoing if 1 slave register is faulty. If 2 slave registers are faulty the resulting load on RP is 1 ingoing and 2 outgoing streams. 2.16.5.5 Control packets:](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-87.png)

Date DRAFT 1.01 2012-01-27 Damm Cellular Systems A/S, Denmark TetraFlex® 7.5 Manual - IP Backbone network layout and configuration TetraFlex® 7.5 Manual 2-158 There will, at all times when the network is activated, be a background load on the router network. The load origins from the control messages exchanged between the BSCs. The control packets will load the router network with 0.3 Kbit/s per active BSC. 2.16.5.6 Log server: The load on the RP relating to a log server being present in the network depends on different factors. The log server must have connection to the multicast network. Any traffic, relevant to the log server, will be signaled to log server at the log server’s multicast address. Log server will – in case it is configured to log a given activity – join the given CMoIP group. Joining the given CMoIP will make the data available for the log server. From this – it is log server configuration and network configuration dependant how the traffic to the log server loads the routers and especially the RP. As it is the same CMoIP stream that is joined – the bandwidth per logged activity is still 22 Kbit/s. 2.16.6 The IP interconnection scheme of TetraFlex® per site All communication between the components of the TetraFlex® is based on IP. In relation to the outdoor type TetraFlex, the SB421 service box with its Windows XP operating system contains a DHCP server. IP address of the SB is x.x.x.10 and the 1st BS421 has IP address x.x.x.11, the 2nd BS421 has x.x.x.12, the 3rd has x.x.x.13 and the 4th has x.x.x.14. In case a redundant SB is in use, it must be numbered x.x.x.19. The SB421 has the LAN address x.x.x.10 or x.x.x.19. The same must be the case for the BSC configuration on the given SB421. In relation to indoor type TetraFlex® – the BSC412 must be configured LAN port x.x.x.10, respectively .19 for redundant BSC. Above address assignments are guidelines. But to ensure efficient support in case of trouble – it is recommended to keep this structure.

If such familiarity does not exist, it is strongly recommended to seek advice with a knowledge Cisco installer. 2.16.8 Recommended router hardware The router hardware recommended from Damm Cellular Systems A/S is a Cisco 1841 modular router. This router type has been tested and verified with the TetraFlex® multisite system. According to Cisco specifications – the 1841 router is capable of processing 75.000 pps (packets per second) – resulting in a theoretical maximum throughput of 38.4 Mbit/s. If this capacity for some reason should not be sufficient – it may be considered to focus on the Cisco 2811 router. This offers 120.000 pps/61.44 Mbit/s capacity plus it offers support for 48V power supply. Other router types and brands may be applicable. But in case the router type is not Cisco – Damm Cellular Systems A/S will not be able to offer any support. 2.16.9 Recommended router firmware The recommended firmware for the Cisco 1841 router is c1841-advsecurityk9-mz.124-15.T1.bin This has been tested and verified with the TetraFlex® multisite system. Any Cisco 1841 deployment with firmware revision lower than the specified – will not be supported.](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-90.png)

Damm Cellular Systems A/S recommends the use of Cisco products and especially the 1841 modular router has been tested and found suitable for this purpose. The following is a brief sketch of the techniques in use in the router network to form a routing that can cater for the needs of the TetraFlex multisite environment. 2.16.10.1 VPN Using IPSec with 3DES encryption on all traffic between the routers maintains security and integrity of the voice and data transported between the nodes in the network. 2.16.10.2 Multicast networking Multicast is a 1-to-many routing scheme. As opposed to unicast which is 1-to-1, the multicast allows a sender of information to address several receivers by sending one instance of the data. The multicast network replicates the sent data as applicable. 2.16.10.2.1 Routing multicast: Protocol-Independent Multicast (PIM) is a family of multicast routing protocols that can provide one-to-many and many-to-many distribution of data over the Internet. The "protocol-independent" part refers to the fact that PIM does not include its own topology discovery mechanism, but instead uses routing information supplied by other traditional routing protocols such as Border Gateway Protocol (BGP) or in this specific case static routing entry. The way PIM is routing is known as RPF, reverse path forwarding. The routing path of multicast packets is based upon the routing path for unicast packets – but is turning it around by 180 degrees. In unicast – the routing table is built on destination i.e. where the packet needs to go. In multicast the routing is based on where the packet comes from. In popular, the PIM forwards packets on all interfaces belonging to a multicast group – except for the receiving interface. A sub configuration of PIM is PIM Sparse Mode (PIM-SM).This version explicitly builds unidirectional shared trees rooted at a Rendezvous Point (RP) per group, and optionally creates shortest-path trees per source. PIM-SM generally scales fairly well for wide-area usage. 2.16.10.2.2 Group management in multicast: The control of members of the multicast environment, i.e. the nodes around the network that need to send or receive multicast traffic is done by Internet Group Management Protocol (IGMP). IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships. It is an integral part of the IP multicast specification, like ICMP for unicast connections. The TetraFlex release 7 supports version 3 of IGMP. Default setting in Cisco is version 2, but can be changed through configuration.](https://usermanual.wiki/Damm-Cellular-Systems-A-S/104012.User-manual-2/User-Guide-1739424-Page-91.png)
