Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Chapter 3: Commissioning This chapter provides post-installation instructions on provisioning, configuring, calibrating, testing, and commissioning the Ripwave Base Station. Review Customer Network Plans As part of preparing to put the BTS into commission, it is important to review the actual installed site against the customer Network Architecture Plan - i.e., checking that all equipment and software are installed and available for use. Verify that all routers are installed and IP addresses are correct. Finally, make sure the installation is approved and signed off by all responsible parties. Install EMS Server The EMS is the management interface for all elements in the Ripwave system. The EMS Server has to be installed on a computer that is connected directly to the Base Station (called the Test EMS) or through the system backhaul (customer EMS). For testing purposes, the Test EMS Server is connected through an Ethernet hub or switch to the Ethernet port found on the front of the BTS (Figure 48). Note that the EMS Server does not support more than one Network Interface Card (NIC). The other port on the front of the CC card is a Serial (Universal Data) Port, also known as the Console Port. Using a laptop/portable computer connected through the data port, an on-site technician can communicate directly with the BTS using a terminal emulation software package. However, this is not recommended. It is always best to rely on the EMS interface for BTS information. When connecting the Ripwave equipment to the backhaul, refer to the Regulatory Information in Chapter 1, Page 8 – specifically regarding cabling to Ethernet or T1 backhauls. Ethernet connections require a UL497B listed protection device to be installed between the BTS and the first network device. T1 connections must be routed from the BTS through a UL497 listed protection device at the demarcation point. The interconnect cables for T1 backhauls must be a minimum #26 AWG wire, in accordance with NEC/CEC standards. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 75 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Figure 48: Ports on CC and MDM Cards Combo/Split Chassis TTA Serial Ports (factory use only) Ethernet Connectors T1 Connectors Serial Port (a.k.a. Console Port) If the customer’s EMS is installed and can be accessed through the backhaul, it can be connected via T1 or Ethernet to the BTS and used for testing purposes. The EMS software installation procedures can be found in the EMS Software Installation Guide, P/N 40-00017-00. After the EMS Server and Client applications are installed, the EMS database needs to be configured with the settings that are designated for the Base Station. The settings are found in the Network Architecture Plan provided by the customer. Verify Cable Connections Before proceeding, verify that all power is connected and present. Ensure that all T1 or Ethernet connections are installed correctly and are active. Verify that the BTS and the RFS are properly installed and that all cables are connected. 76 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Configure & Power Up the BTS Overview During initial power up a minimal set of configuration parameters have to be input to the BTS through the serial port on the CC card. These early configuration parameters are referred to as the “boot parameters”. They are required to get the BTS to communicate with the EMS Server so that all the configuration data can be downloaded from EMS to the BTS. The PC used at this point is a Test EMS Server (i.e., laptop). If the customer’s actual EMS Server is available, a separate Test EMS (i.e., laptop) may not be necessary. For simplification, whether it is a Test EMS laptop or the customer’s EMS Server, we refer to the device at this stage as the Test EMS. Set Up the Test EMS Typically, in order to keep a constant link an Ethernet hub (10/100 Base-T) connects the Test EMS to the BTS via a male to female RS-232 cable connected to the CC serial port. A connection between the serial port on the CC and the serial port on the Test EMS is also used. Standard communication software, i.e., a standard terminal emulation program, such as Windows HyperTerm or TeraTerm, is used during these early configuration stages. Step 1. Verify all RF cables going to the BTS are securely connected to the proper connector. Step 2. Connect an Ethernet cable to the Ethernet connector located on the CC card and to an Ethernet hub. Connect another Ethernet cable from the Ethernet hub to the Ethernet connector on the PC containing the Test EMS Server and Client applications. Step 3. Connect an RS-232 cable (DB-9 male to female) to the serial port (UART) located on the CC card to the serial port connector on the Test EMS computer. Note: A VT 100 terminal or any standard Windows based ASCII terminal emulation program can be used for connecting to the serial port. The connection for HyperTerminal is explained here. The steps to get to the HyperTerminal program may be different due to variances in the Operating Systems and in the setup of the PC. Step 4. Power on the Test EMS Server. Step 5. On the desktop, go to Start > Programs > Accessories > HyperTerminal > HyperTerminal (using whichever terminal emulation program you are running). Step 6. In the COM1 Properties window (Figure 49), under the Port Settings tab, enter the following configuration options. Click OK. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 77 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Figure 49: COM1 Properties Bits per second: 9600 Data Bits: Parity: None Stop Bits: Flow Control: None Step 7. On the Test EMS Server, click on the Server icon to start the EMS Server. NOTE: This step assumes you have loaded and configured the EMS Server & Client applications. Step 8. Click on the EMS Configuration & Alarm Manager (CAM) icon to start the EMS Client GUI. Step 9. At the EMS Configuration & Alarm Manager login screen, enter the user name and password. The defaults are both emsAdmin. Add BTS in EMS Once you have the CAM application running on the Test EMS server, you will need to click on the BTS element tab to add the new BTS. Only the minimal configuration parameters have to be completed at this time - i.e., BTS name, ID, IP address, subnet mask, and gateway. Follow the Network Architecture Plan designed for this system. Also configure the GPS offset time. The default is 0 minutes, indicating the BTS would be located in the same time zone as Greenwich Mean Time (GMT). Change this value to whatever time is appropriate to the location of the BTS in relation to GMT time zone. For example, if the BTS is located in Dallas, Texas, which is 6 hours behind GMT time zone, you would enter –360. As you will see in the section that follows, you will also configure the RFS splitter loss at this time. For more details about configuring a BTS, refer to the Ripwave Configuration Guide. 78 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Configure RFS (Splitter Loss Value) Each RFS shipped is pre-programmed for the customer’s specific operating environment. An RFS Configuration CD accompanies the RFS equipment when it is shipped. The CD includes an RFS script and a Quick Guide with procedures on selecting the appropriate splitter loss values to be entered into the EMS database for the given Base Station. Each Configuration disk is unique to the individual RFS that is shipped. You cannot use the same disk on other RFS equipment. RFS Configuration Procedure Step 1. Remove the RFS Configuration disk from the RFS packaging, and insert it in the floppy drive of the Test EMS. Step 2. Copy the folder named “RFS” that is on the disk to the Test EMS Server:/scripts. It will take approximately 20 seconds to complete. Step 3. Open the new folder on the EMS server. You will see a list of file names. The format of the file names is as follows: RFS_serial number_frequency.cli Example: “RFS_024300001_2402500.cli” - This example of the configuration file is for an RFS with serial number 024300001 and a center frequency of 2.4025. Verify the correct serial number in the file name against the serial number of the RFS equipment. The equipment serial number may be found on the back of the RFS panel or on the side of the bottom cylinder of the omni antenna. Step 4. Determine which file you need to run, depending on the provisioned frequency of your BTS. NOTE: For 2.6 GHz systems, select the frequency that is closest to your provisioned center frequency. To find the provisioned center frequency for your BTS, open the EMS Configuration & Alarm Manager (CAM) application. Select the BTS tab and specific BTS, then Air Interface / Layer 2 / Carrier Data / Show Configuration. This will display the center frequency information. Step 5. Open the selected CLI file for editing using any text processing application program. Note the power splitter values listed there (i.e., write them down or print them out). Step 6. Modify the line that starts with “bts” by changing the BTS ID for your BTS. The default is “BTS 1”. For example, if the ID for your BTS is 252, change the “1” to “252”. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 79 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Step 7. Save this file as text, and then close it. Step 8. Start the EMS Config CLI application to run “script ”. Do this by entering the following: >enable >configure >script scripts/rfs/rfs_ _<7-digit frequency>.cli NOTE: For Unix operating systems, the CLI text is case sensitive and the slash marks should be backward slashes instead of forward slashes. Step 9. View the Power Splitter values in EMS to verify that the CLI script ran as expected. The Power Splitter values may be found under Layer 1 / Show Configuration > Antenna Table. You will need to “Refresh” the active screen to view the updated information. Step 10. Type “Exit” twice to exit the Config CLI edit mode. Power Up BTS Now you are ready to power up the BTS. Step 1. Ensure that input power has been connected to the BTS. Step 2. Switch the Power to ON. If the BTS is a Combo Chassis, the switch is located on the top right front of the BTS. The green Power On light next to the switch will illuminate (Figure 50). If the BTS is a Split Chassis, the Power ON switch is located on the back lower middle of the Digital shelf. The green LEDs on the RF/PA modules and the circuit cards in the BTS chassis should illuminate. The Power switch for the TTA is located on the lower middle back of the chassis. 80 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Figure 50: BTS Power On Switches Combo Chassis Power ON/OFF Split Chassis Off/On switch Step 3. Watch for the auto-boot countdown command. Type in config on the computer keyboard to interrupt the standard boot sequence. The window of time to type in “config” after auto-boot starts is 20 seconds. BTS Bootup The BTS is shipped with a default value of a 20-second countdown to interrupt the standard bootup sequence. You can escape the standard bootup when the display shows the following: autoboot countdown : quick [quick|delayed] To escape the initialization sequence, type in config before the 20-second counter reaches zero. Note: Under the next section, “Boot Prompt”, you will see how to disable the 20-second countdown in lieu of a shorter, 1-second countdown. This will minimize downtime during unattended restart conditions, for example, if there is a power outage and the BTS is recovering. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 81 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Boot Prompt After you have escaped from the automated boot sequence, the console will display a rudimentary Boot prompt: [Navini Boot]: This prompt offers the ability to perform a small set of operations. Enter ‘?’ or ‘h’ followed by the Enter key to display a list of commands (Exhibit 1). To invoke any of the commands, simply enter the single letter command with optional parameters, followed by the Enter key. Exhibit 1: Boot Commands [Navini Boot]: ? adrs[,n] adrs adrs, nbytes, value adrs, adrs, nbytes print this list resume boot sequence print boot params change boot params display memory modify memory fill memory copy memory @ – Use this command once all parameters have been set as desired. This will resume the boot initialization sequence that you escaped from previously. p – This command displays a concise representation of the current parameters used for boot configuration. c – Use this command to alter the current boot parameters. Once selected, a detailed sequence of options is prompted, and is covered in detail later. After all of the items in this list are completed, you return to the [Navini Boot]: prompt. This option sequence allows you either to accept the current value by pressing the Enter key or to enter a new value from the range or values listed, followed by the Enter key. Additionally, you can enter ‘.’ followed by the Enter key to erase the current value of an item and return it to a default state. If you make an error, you can choose ‘-‘ (hyphen) followed by the Enter key to return to the previous item in the list. Alternatively, you can fix an error by proceeding with the selections and select ‘change' when you return to the [Navini Boot]: prompt. d – Display memory allows you to display portions of the BTSs memory with user-defined values. It should only be performed with the assistance of a certified Navini service technician. m – Modify memory allows you to alter portions of the BTSs memory with user defined values. It should only be performed with the assistance of a certified Navini service technician. 82 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 f – Fill memory allows you to alter portions of the BTSs memory with a fixed pattern. It should only be performed with the assistance of a certified Navini service technician. t – Fill memory allows you to alter portions of the BTSs memory with a pattern from another area of memory. It should only be performed with the assistance of a certified Navini service technician. Ethernet Configuration The Ethernet configuration is grouped into three sections: general, EMS, and traffic path. An example of the Ethernet configuration parameters is shown in Exhibit 2. Exhibit 2: Ethernet Configuration [Navini Boot]: p date and time autoboot countdown ems inet snmp community traffic path mac address ip on enet (active) ip on enet (standby) netmask on enet ip on backplane gateway on enet 01/09/2003[10:19] MM/dd/yyyy[hh:mm] delayed [quick|delayed] 172.16.0.10 public enet [enet|atm] 00:04:6a:00:01:20 172.16.23.181 172.16.23.182 255.255.0.0 10.0.0.1 172.16.0.100 General The general section offers you the ability to change the date and time manually. If a GPS has been installed, the BTS will automatically set the date and time: date and time : 08/21/2002[13:21] MM/dd/yyyy[hh:mm] When this line is displayed, the current date (08/21/2002) and time [13:21] are displayed. Accept the defaults by pressing the Enter key, or enter “date” at the console and a new value using the format indicated in military time (Hours 1-24). All 5 fields must be entered as specified. Leading zeroes can be omitted. Previously, it was mentioned that the 20-second auto-boot countdown timer can be disabled and a 1 second countdown can be used instead. To enable this feature, change the autoboot countdown item from “delayed” (which is 20 seconds) to “quick”, which is 1 second: autoboot countdown : delayed [quick|delayed] Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 83 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 EMS This section concerns the configuration of the EMS Server itself. First, the Internet (inet) IP address of the Server is specified. Make sure to fill this field with the address of the Server used to configure this BTS. Your BTS is shipped with this field un-initialized. You must provide a valid 4-digit IP address before you can proceed. For example: ems inet : 172.16.0.10 The second parameter that you must specify to allow the EMS Server to recognize this BTS is a community string for the EMSs Simple Network Management Protocol (SNMP) interface. The default community string shipped with the BTS is “public”. Press the Enter key to accept this default, or type in a new value and press the Enter key to alter it: snmp community : public Traffic Path The last major block of configurations required for an Ethernet backhaul to the BTS is the traffic path parameters. The first prompt instructs the BTS to use the Ethernet as the WAN (backhaul) configuration. It must be set to “enet” for an Ethernet backhaul. If “atm” is selected, proceed with the description in the ATM or IMA sections. The BTS is preconfigured to use Ethernet for the WAN connection. Press the Enter key to accept this default: traffic path : enet [enet|atm] The BTS address is specified next. Every BTS must be uniquely addressed and have values that equate in the EMS configurations. This address information defines the Layer 2 parameters first, and then it defines the Layer 3 parameters. For Layer 2, you are only given an opportunity to see the Ethernet Media Access Control (MAC) address used by this BTS. This is a unique number programmed in the BTS. You cannot alter it. However, situations may develop in which you need to know the MAC address and, therefore, need to display the information. For example: mac address : 00:04:6a:00:01:20 Next are the IP addresses that represent this BTS: one for the active CC card and one for the standby CC card. Enter the IP for the active controller card, for 172.16.23.181, and the next IP (172.16.23.182) is automatically assigned to the Standby card. ip on enet (active) : 172.16.23.181 ip on enet (standby) : 172.16.23.182 84 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 The standby field is only displayed for your convenience and cannot be altered. Note that the BTS automatically handles switching the address when a failure occurs on an active Controller card, requiring the standby Controller to go into service. However, the MAC addresses remain fixed. Coupled with any IP configuration is a need to specify the corresponding subnet mask. Refer to common network administration literature for guides on addresses, networks, masks, and gateways. In short, the subnet mask identifies the portion of the IP address that is common to those devices connected to the same Ethernet. The most important “other” device is the BTSs default gateway (specified later). The portion is identified using a logical “and” of the mask with the address. For example, a subnet mask of 255.255.0.0 and with an IP address of 172.16.23.182 yields a network of 172.16.x.x. In this case, the default gateway must also be on the 172.16.x.x network. The BTS requires that this association be met. If not, you will be asked to try again. netmask on enet : 255.255.0.0 The BTS uses a high-speed Serial Line Internet Protocol (SLIP) connection to communicate with the redundant T1/Controller Card. This interface is only used internally and has a fixed subnet mask of 255.255.255.252. The host portion of the address –that is, the least significant 2 bits– is automatically provided by the software based upon slot ID. However, you may want to alter the default network address to avoid conflict with your network. The BTS is shipped with the 10.0.0.0 network as the internal network. This is a reserved network not used on the Internet. However, if your private network utilizes this private address space, you may need to change it to avoid the conflict. ip on backplane : 10.0.0.1 As for the default gateway for the BTS, all traffic routed outside the directly connected Ethernet port goes through the gateway. Furthermore, the gateway must be reachable on the directly connected Ethernet port. Therefore, the BTS will prevent you from entering a default gateway address that fails the logical “and” test discussed previously. This address is specified on the line item shown below: gateway on enet Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 : 172.16.0.100 85 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 ATM/T1 Configuration For an ATM/T1 configuration, the items shown in Exhibit 3 are identical to Ethernet with the exception of the traffic path, which must show “atm” for this type of configuration. Exhibit 3: ATM/T1 Configuration date and time : 01/09/2003[10:22] autoboot countdown : delayed ems inet : 172.16.0.10 snmp community : public traffic path : atm mac address : 00:04:6a:00:01:20 ip on atm (active) : 172.16.23.181 ip on atm (standby) : 172.16.23.182 netmask on atm : 255.255.0.0 When ATM is selected for the WAN interface using the traffic mode parameter, an additional set of parameters is required (Exhibit 6). First of all, another IP address must be identified for the ATM interface. The ATM IP address cannot be the same as the Ethernet IP address. In this case, the Ethernet IP address is only used for debug purposes and is a non-routed interface. This means that the BTS can only reach other computers directly connected to the Ethernet port of the BTS. The only routed interface available is through the ATM port. This routed interface address is specified with the “ip on atm” line item and the corresponding netmask parameter (Exhibit 4). The information on network address specifications from the Ethernet Configuration section of this chapter applies to ATM as well. For ATM, the only gateway allowed for the BTS is on the ATM interface, as specified here. Exhibit 4: Additional ATM Parameters ip on atm (active) ip on atm (standby) netmask on atm ip on backplane gateway on atm 172.17.0.101 172.17.0.102 255.255.0.0 10.0.0.1 172.17.0.100 For an ATM system, the BTS must have some additional configuration for the Management Private Virtual Channel (Management PVC). Recall the boot parameter philosophy discussed before. The boot parameters only identify those settings required to allow the BTS to reach the EMS. Note that the boot parameters only allow specification for one PVC (the Management PVC), which is used to reach the EMS. All user traffic PVC parameters are specified in the EMS configuration. Ensure that the EMS parameters for the Management PVC match those being set here through the boot prompt. If not, as soon as connection is made with the EMS, the Management PVC will be reconfigured and can potentially disconnect the BTS from the network. 86 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 The PVC configuration is broken into 3 sections: ATM layer parameters; optional Inverse Multiplexing over ATM (IMA) parameters, and T1 physical layer parameters. The first item selects which ATM interface will be used for the Management PVC. If IMA is not selected, you may select from one of the 8 T1 ports numbered 1-8 using the option t1-N, where N is the port number. This is the same interface port number specified in the EMS. If IMA is desired, reference the following section: pvc type-atm i/f : t1-0 [t1-(1-8)|ima-(1-2)] The circuit identifier for this segment of the Management PVC is the next item specified. The first parameter identifies the maximum number of bits for any PVCs identifier Virtual Path Identifier/ Virtual Channel Identifier (VPI/VCI) pair. The BTS restricts the available set to 13 total bits. However, you are free to divide those 13 bits between the VPI and VCI as needed, with the VPI having a maximum allocation of 8 bits. You can choose the number of bits for each by selecting two values separated by a “:”. Or you may select the BTS default of 3 VPI bits and 10 VCI bits by pressing the Enter key: pvc id size vpi:vci : 3:10 [1-8:1-13] Having specified the number of significant VPI and VCI bits, now select the actual identifier. The BTS will restrict the values entered for the VPI and VCI to the ranges you selected in the previous size specification. For instance, if 3:10 is selected as a size allocation, the VPI must be between 0 and 7. Again, you can select the values for the VPI and VCI separated by a “:” or accept the default value of VPI = 1 and VCI = 100 by pressing the Enter key. Be careful not to use the reserved VCI values from 0-15 that are often used in ATM networks for Operation, Administration, and Maintenance (OAM) purposes. pvc vpi:vci : 1:100 [0-255:16-8192] The service category for the Management PVC is specified next. The choices are Unspecified Bit Rate (UBR) or Constant Bit Rate (CBR). Other ATM service categories are available for traffic PVCs, but those are specified in the EMS configuration. UBR and CBR both require a set data rate and delay variation parameter. The data rate is specified in cells per second in the ATM Traffic Contract’s Peak Cell Rate (PCR) field. The delay variation is in the ATM Cell Delay Variation Tolerance (CDVT) in the ATCs CDVT field. Specify the PCR and the CDVT values separated by a “:” or chose the default by pressing the Enter key. pvc service category : ubr [cbr|ubr] pvc atc pcr:cdvt : 3641:100 [1-3641:0-100] Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 87 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 The final set of values is used to configure the T1 parameters. The line type allows you to select Extended Super-Frame (ESF) or D4. ESF format is the standard format for ATM/T1 applications. D4 format is supported as an alternate; however, T1 signaling capabilities may be limited. Check your network plans for a definition for your specific application. line type : esf [esf|d4] Additionally, you must choose a line coding type: line coding : b8zs [b8zs|ami] The approximate length of the T1 line is specified next. It is used to control the signal conditioning used on the T1: line length (ft) : 500 Finally, the T1s timing source must be specified. A T1 uses only one timing source either at the near-end or far-end of the line. You may select the BTS as the originator of the timing source by selecting “local”, or you may select the far-end as the timing reference by selecting “loop”. line clock source : loop [loop|local] IMA Configuration If you decide to utilize IMA groups to pool the T1 resources, then the same parameters described for the ATM/T1 Configuration above also apply to configuring IMAs. Refer to Exhibit 5. Exhibit 5: IMA Configuration date and time ems inet snmp community traffic path mac address ip on enet (active) ip on enet (standby) netmask on enet ip on atm (active) ip on atm (standby) netmask on atm ip on backplane gateway on atm 08/21/2001[10:22] 172.16.0.10 public atm 00:04:6a:00:01:20 172.16.23.181 172.16.23.182 255.255.0.0 172.17.0.101 172.17.0.102 255.255.0.0 10.0.0.1 172.17.0.100 In addition, the ATM interface must be specified as IMA and reference one of two IMA groups used for the Management PVC. This IMA group must match what is identified in the EMS. Use “0” for the first group and “1” for the second group. 88 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Each group identifies a set of T1 ports that are being combined to form one larger virtual port. For the sake of boot parameter specification, ALL T1 interfaces for the Management PVCs IMA group are assumed to be identical. So the parameters for T1 specifications apply to all T1s of the IMA group: pvc type-atm i/f : ima-0 Once the IMA interface is selected, a set of IMA parameters must be specified for the IMA group used by the Management PVC. An IMA group inherently supports dynamic addition and drops of individual T1 facilities from the group to facilitate fault tolerance to failed T1 facilities. The minimum number of T1 ports, or links, that must exist for the IMA group to function is specified here. A value from 1-7 is required for each one of the receive and transmit directions. Separate the values with “:”. You can increase the values from the default of 1 link in each direction or accept the default by pressing the Enter key. ima min rx:tx links : 1:1 [1-7:1-7] Next, specify which T1 ports are used to form the IMA group. This is a list of T1 port identifiers (1-8), each separated by commas. The BTS makes sure you enter at least as many links as you specified for the minimum requirements above: selected ima links : 1,2,3,4,5,6,7,8 The near- and far-end IMA protocols use an ID number to identify each other. This value must agree with that provisioned at the far-end of the IMA link. The BTS defaults to a value of 0, but you can specify any value from 0 to 255: ima group id : 0 [0-255] Group symmetry modes allow symmetric or asymmetric operation of IMA links: ima symmetry : sym [sym|asym|asym-cfg] IMA frame length specifies the size of the IMA frames that are being transmitted: ima frame length : 128 [32|64|128] The IMA alpha/beta/gamma parameters are used by the IMA frame synchronization mechanism.: ima alpha:beta:gamma : 2:2:1 [1-2:1-5:1-5] The IMA clock mode selects either a common or independent IMA clock mode (Exhibit 6). It is the same as for ATM/T1. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 89 Ripwave Base Station I&C Guide Navini Networks, Inc.

This is a fixed process that cannot be altered in the field. Auto-booting is the process that can be escaped by user intervention, (i.e., enter “config”), in order to enter the boot prompt.

This file system is used to store operating code images, configuration data, and log files. The BTS Operating System software handles the images, data, and files and does not require operator assistance. There are three on-board file systems’ FLASH and RAM drives. The FLASH drive is at /tffs0 and the two RAM drives use /dev0 and /dev1. All on-board file system drives have dedicated functions and should not be altered or used through manual operations.

The TCP, UDP, IP, and ARP protocol stacks are created. Interfaces for the stack are then created and attached to the stack. Three or four interfaces are created depending on the selection for “traffic path” in the boot parameters. The Fast Ethernet Controller, fec (0), is created and attached for the 10/100 Ethernet ports on the BTS. If “atm” is selected, then a WAN Ethernet Controller, WEC (0), is also created and attached to the stack to perform RFC1483 Ethernet bridging onto the ATM interface. Internally, the BTS utilizes a high-speed SLIP interface, sl (0), to provide communication between redundant devices. Finally, a debug local loopback interface, lo (0), is created and attached.

After initial installation and provisioning through the boot line, “EMS” is selected as the Config Data Source. In this case, all remaining parameters are downloaded from the EMS. Once the BTS and EMS have synchronized and ownership of individual elements in the MIB negotiated, subsequent reboots of the BTS will indicate the local “BTS” copy of the MIB is being used. This reduces the burden and start-up time of a system-wide restart: Selecting Config Data Source as BTS ......Done Once the MIB information is identified, the SNMP agent is initialized. At this point, the EMS can begin communicating with the BTS via this agent: Initializing SNMP Agent ..................Done The BTS tests that a path through the WAN exists to its EMS Server.

Chapter 3 Calibrate the Base Station Calibrating the Base Station detects the phase differential between the antennas and matches the output power across all antennas in the RFS. The calibration procedure must be performed at least three times to verify consistency of the returned values. Ensure that the BTS has been powered on with the power amplifiers on for at least fifteen minutes to allow them time to warm up and stabilize. Calibration Procedure To calibrate the BTS, follow the steps in the procedure below. Refer to the Ripwave Configuration Guide, as needed. Step 1. On the Test EMS, click on the Server icon to start the EMS Server. Step 2. Click on the EMS Configuration icon to start the EMS Client GUI. Step 3. At the EMS Configuration & Alarm Manager login screen, enter the user name and password. The defaults are emsAdmin / emsAdmin. Step 4. Verify that Antenna Power, RX Sensitivity, and Cal Cable Loss values are entered in the fields in the EMS. NOTE: The Power Splitter Loss was entered when you performed the RFS configuration earlier. Step 5. Click on the BTS that is being installed to select it. Right-click on the highlighted BTS and select Action > Configure. Refer to Figure 51. Figure 51: Select BTS 100 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Step 6. Click on Air Interface > Layer 1, and then click Calibrate. In the resulting dialog box (Figure 52), select FULL CALIBRATION and Calibrate. Figure 52: Calibrate BTS Step 7. When the Warning window appears (Figure 53), click Yes. Figure 53: Warning Window Step 8. The Full Calibration window appears during system calibration (Figure 54). When calibration is complete, the Full Calibration window changes and displays the finish time and the result. Click the Close button to close the Full Calibration window. Note that the result of “Done” does not mean that the system passed calibration. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 101 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Figure 54: Full Calibration Window Step 9. Click Show Configuration and select the Antenna Table tab (Figure 55). Check the Tx Gain and Rx Gain columns (the last two columns in the table) for transmit and receive results. The transmit and receive results for all the eight antennas must be between 1 and 254. The eight values in each column should be relatively close to each other. A value of zero indicates a problem with the associated antenna path. Figure 55: Show Configuration/Antenna Table 102 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Step 10. Perform the calibration function two more times. Ensure each time that the values remain relatively stable (+/- 3), and that none of the results is zero. After you perform the second calibration, click on Configure. The Config Layer 1 Data window (Figure 56) shows the data from the second calibration. The values in the main screen from the Show Config selection are from the first calibration. Compare the values from the two calibrations to ensure that they are stable, and not equal to zero. Figure 56: Config Layer 1 Data Window Step 11. Close the Config Layer 1 Data window. Update the main screen by clicking the Show Configuration button. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 103 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Perform the Calibration Verification Procedure Base Station Calibration Verification is a set of procedures to verify that the equipment has passed calibration and that the RF portion of the equipment is operating within acceptable parameters. The results of the tests should be documented in the Base Station Calibration Verification Form, P/N 40-00059-00. This form, along with the procedure and form instructions, may be found in Appendix V. Single Antenna Test The object of the RFS Single Antenna Test is to verify the functionality of each antenna element in the Ripwave Radio Frequency Subsystem (RFS). The 8 antenna elements work together to create the beamforming that results from using a Smart Antenna - Phased Array technology. Using 8 combined single antenna elements creates the beamed radiation that is part of what constitutes the gain of up to 18 dB during transmission of data. In order to verify the correct beamforming and that each single antenna is working properly, we have to turn off the individual PA that controls each antenna element, one at a time. The Single Antenna Test should be performed after completing the Base Station Calibration Verification procedure. This test is necessary since an equipment calibration does not check the functionality of the RFS, and the Calibration Verification only searches for losses in the RFS, not RFS functionality. More specifically, the Single Antenna Test checks the following: 1. Low Noise Amplifier (LNA) at the RFS. LNAs are an integral part of the smart antenna technology. 2. Power Amplifiers. There is one PA for each antenna element, for a total of 8. Each PA converts IF to RF and vice versa and amplifies the signal before transmission and after reception. 3. Modulations. As each antenna element is checked, the variable modulations are checked. The higher the modulation, the higher the power and the better the data rate. The test ensures that all modulations possible, i.e., QPSK, 8PSK, and QAM16, are working properly. Export BTS Data Once you complete the calibration verification, export the BTS configuration data to a text file. This is done by highlighting the specific BTS in the Configuration and Alarms Manager (CAM) window, and on the Main Menu select File > Export BTS Data. This saves the configuration information if needed for later retrieval. 104 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 Perform Local Modem Tests Local wireline, then over-the-air, Modem testing will verify that the Base Station is working properly and is able transmit and receive data. Data rates are not being checked at this time. Refer to Appendix W to set up and perform the Local Modem procedures. Install & Test Customer EMS Operations If you have been using a Test EMS up to this point, you will now need to install and test the customer’s EMS server. This involves installing the EMS Server and Client on a computer that is connected through the system backhaul. When connecting the Ripwave equipment to the backhaul, refer to the Regulatory Information in Chapter 1, Page 8 – specifically regarding cabling to Ethernet or T1 backhauls. Ethernet connections require a UL497B listed protection device to be installed between the BTS and the first network device. T1 connections must be routed from the BTS through a UL497 listed protection device at the demarcation point. The interconnect cables for T1 backhauls must be a minimum #26 AWG wire, in accordance with NEC/CEC standards. If the customer’s EMS is already installed and has been used for testing purposes, skip to the “Verify System Performance” section of this chapter. Install EMS Software The EMS software installation procedures can be found in the EMS Software Installation Guide, P/N 40-00017-00. After installing the EMS Server and Client applications, the EMS needs to be configured with the settings that are designated for the Base Station. The settings are found in the Network Architecture Plan provided by the customer. Ensure connection between the Base Station and the backhaul. The connection to the Base Station will be either an Ethernet connection or T1 connections. Verify EMS to Base Station Connectivity Follow the steps below to ensure the EMS and Base Station can communicate. Step 1. Open a Command Prompt window on the computer where the EMS is installed. Step 2. Ping the Base Station using the CLI command ping . Verify that a reply from the Base Station is received. Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 105 Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 3 Perform Calibration Using Customer’s EMS This step is necessary only if you have been using a Test EMS up to this point. You will need to install the customer’s EMS server and software. Calibrate the Base Station using the customer’s EMS. Follow the same calibration procedures described earlier in this chapter, Calibrate the Base Station. Perform the procedure three times and make sure that the results are stable (+/–3). Verify System Performance Drive Study The preliminary Drive Study is performed if no RF coverage model is available. The Drive Study helps you to map out the coverage area. Later, the full Drive Study is performed to see if the system’s coverage area is as predicted and, if necessary, to fine-tune the RF model. Following the detailed Drive Study procedures in Appendix X, you will perform a preliminary Drive Study by driving back and forth through a sector, staying on major roads about a kilometer apart. Special attention has to be paid to the null and fringe areas. You will follow this scheme for each sector in the site, recording the results of all tests. The test results will be sent for evaluation, along with the Location (FTP) test results, to Navini Networks Technical Support. If the results are not adequate, Technical Support will have you adjust some of the RF parameters and perform the Drive Study again. Location (FTP) Test Location Tests are performed to see if the system file transfer functions are working as predicted between CPE and Base Station. These are conducted in stages as well. The first stage is the preliminary Location Test, where you perform three uploads and three downloads at three locations with the Base Station in line-of-sight (LOS). Then you perform three uploads and three downloads at three locations with the Base Station in non-line-of-sight (NLOS). For the NLOS testing, you will need to find an obstacle, such as a building, between the CPE and Base Station. Results are sent, along with the preliminary Drive Study results, to Navini Networks Technical Support for evaluation. If the results are not adequate - i.e., file transfers do not meet customer’s objectives - Technical Support will have you adjust some of the RF parameters and perform the Location tests again. The detailed Location Test procedures and form are located in Appendix Y. To summarize, these are the high-level steps for verifying system performance: 1. Conduct preliminary Drive Study (if no RF coverage map is available). 2. Conduct preliminary LOS Location Tests. 3. Conduct preliminary NLOS Location Tests. 106 Part #40-00047-07 Rev F v1.0 (TTA) October 9, 2003 Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 3 4. Send all test results to Navini’s Technical Support for evaluation. 5. If directed by Technical Support, adjust RF parameters. 6. Conduct full Drive Study. 7. Conduct full LOS Location Tests. 8. Conduct full NLOS Location Tests. 9. Send all test results to Navini’s Technical Support for evaluation. The cycle continues until the performance objectives are reached. Verify System Operation With Multiple Modems Set up three computers with Modems connected to them. Perform file transfers from all three computers to verify Base Station operation. Back Up EMS Database After all system installation and commissioning activities are complete, perform a backup of the EMS database. The procedure can be found in the EMS Administration Guide. Place the backup files on a different system server where they will be periodically backed up on a tape drive. Customer Acceptance To conclude the installation and commissioning activities, gather all of the required documents and forms from the installation and commissioning procedures to create a comprehensive system I&C package. Refer to Appendix Z for a summary of the documentation package. The customer and Navini Networks will sign the Customer Acceptance Form. A copy of this form is provided in Appendix AA. The signed form and the system I &C package are provided to the customer. The original, signed Customer Acceptance Form and system I &C package are stored in the Navini Networks Technical Support database.
