ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup A CPU called the Hubmaster is a special Hub node that controls tenant processing for Digivance CXD nodes on its subnet. For a definition of tenant sectors, see Section 6.1. The Hubmaster also functions as a time server for a Digivance CXD subnet (using Network Timing Protocol), and can be set up to provide DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name Service) to its subnet as well.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup Table 3-1.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup • Ensure that FBHDC modules are connected to FSC modules. (See Hub Installation and Maintenance Manual for details) • An RF chassis in a Hub rack contains enough slots for 2 sets of tenant RF equipment, where a set of tenant RF equipment consists of one FSC, one HUC and up to two FBHDC’s.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 6.2 BTS Connection MIB Within the Hubmaster node, the BTS Connection MIB is used to create new tenant base station sector instances (simply called "tenants" from here on) to be configured, monitored, and controlled in the Digivance CXD system.

Select the I2C Bus and Slot of the FSC module to that of its corresponding BIM. Set the I2C slot value to “2”.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 6.2.9 Composite Mode The Digivance CXD default forward gain balance is called “composite mode”. In this mode, a composite RF signal will have gain of +42dB (Cell/SMR) and +45dBm (PCS) through the system. The maintainer is responsible for ensuring the desired signal level into the system. See Table 3-3 for sample input and output signal strengths: Table 3-3.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup • The Tenant ID sub-string is comprised of four particular pieces of information: Tenant Name, BTS ID, BTS Sector, and Tenant Band. These four pieces of information form the Tenant ID sub-string, where each piece of information is delimited by a single character (currently a colon ":"). • The IP Address sub-string indicates the IP Address of the CPU node that transmits the pathtrace string.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup Figure 3-2. Tracing Pathtrace, Two Tenants 6.3.4 Pathtrace Reverse Transmission The RDC is the originator of the pathtrace string in the reverse paths of the system. However, it is desirable to maintain continuity between the forward and reverse pathtrace strings.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup In the Hub, the RSC module receives the pathtrace strings from several RDC’s into its FPGA from its DIF input connection. The RSC HCP reports the received input pathtrace strings in its MIB for use by higher-level processes, as described in sections below. The RSC has the added responsibility of determining the "majority inputs" to determine the most-prevalent input pathtrace based on Tenant ID sub-strings.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 7 TENANT CONFIGURATION The Tenant OAM MIB is the primary interface for configuring the operating parameters of tenants in the Digivance CXD system. The Tenant OAM MIB is used exclusively at the Hubmaster node, where any changes made to operating parameters are validated and pushed down to the proper node(s) by Tenant processing. 7.1 Setting Protocol transceptTenantOAMTable.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 7.6 Setting RAN Forward Gain Offset transceptTenantOAMTable.transceptTenantRanForwardGainOffsetX, where X = 1-8 The RAN Forward Gain Offset is a parameter in the Tenant OAM MIB that allows the target RAN Gains for this tenant to be adjusted. This effectively allows the cell coverage provided by a given RAN to be adjusted.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 7.11 Using Tenant Mode transceptTenantOAMTable.transceptTenantMode Tenant Mode is a parameter in the Tenant OAM MIB that will allow the tenant to be put into a special mode such as "disabled", or "test",. This functionality is not currently supported in the Digivance CXD software. 7.12 Enabling / Disabling Delay Compensation transceptTenantOAMTable.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 7.15 Enabling / Disabling RAN slots transceptTenantOAMTable.transceptTenantRanDisableX, where X = 1-8 The RAN paths belonging to a tenant can be disabled using the RAN Enable/Disable parameters of the Tenant OAM MIB. Doing so will disable the PA in the RAN. These MIB fields are enumerated types with values "Enabled" = 0, and "Disabled" = 1.

ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 8.2 Bracketing of Lost RANs When a RAN CPU is removed from the network, or if tenant processing is unable to communicate with one of its RANs, then that RAN ID in the Hostname table is bracketed. For example hostname would be reported as [hostname]. In addition, the RAN ID in the Address table is also reported in a different fashion when a RAN is "lost".
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup There are two main ways to access the output of NIPR/S for use in the identification of related nodes. The most accessible way is to utilize SNMP to view the Hub Node MIB and RAN Node MIB at the Hubmaster node. To get an unbroken list of Digivance CXD IP addresses that the Hubmaster is currently servicing, telnet into the Hubmaster node on port 7401. No user name or password is necessary.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup There are two default user accounts that come standard in the Digivance CXD network. The “operator” account has access to the Digivance CXD binaries and is used for regular maintenance. The “root” account has full access privileges to the entire file system. In addition, the “operator” account has “sudo” privileges, which may be modified by the network operator to tailor operator access.

It is expecting as input the IP address of each Domain Name Server that the Hubmaster node can connect to. If there are no upstream DNS servers, leave this entry blank.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 10.2.2 Incorporating Existing LAN DHCP Using a pre-existing LAN DHCP server is ideal when the Digivance CXD network only contains one Hubmaster node. In this configuration, there is no need for a router between the Hubmaster and the rest of the LAN, since all nodes are on the same subnet.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 10.2.5 Incorporating Existing LAN DNS The method of incorporating an existing LAN DNS begins with configuring the Hubmaster DNS forwarding as outlined in Section 10.1.5 and continues with some maintenance at the upstream DNS. At a minimum, the upstream DNS needs to be updated with each Hubmaster node’s IP address and full hostname (including its domain).
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 11.1.4 Hostname transceptHubNodeTable.transceptHubNodeHostname This entry shows the hostname of the CPU occupying a specific index of the Hub Node MIB. This entry is automatically set up by Digivance CXD system software. Changing hostnames on Digivance CXD nodes is not recommended, but can be accomplished by logging into the target node. 11.1.5 IP Address transceptHubNodeTable.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup For cases where a GPS receiver is not present and it is desired to manually enter the GPS coordinates, the Hub Node MIB contains two MIB fields to configure the GPS longitude and latitude settings. Since only the Hubmaster node in the Digivance CXD system contains a GPS receiver, these MIB fields will not be used for Hub Slave nodes.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup 11.2.4 Site ID transceptRanNodeTable.transceptRanNodeSiteID This entry displays the RF Network’s Site ID where each RAN is installed. In conjunction with the Pole Number, this is the mechanism used to pinpoint any RAN’s physical location. GPS can also be used, where available. The Site ID may be 64 characters long. Note: For tenant information propagation to occur, this field must be populated. 11.2.
ADCP-75-192 • Issue 1 • December 2005 • Section 3: Network and System Installation and Setup from this MIB, the operator must set the “Clean” value to 1. The old node information will be removed. No further action is required. Note that if the node is present and valid, it will reappear within seconds, even if it is cleared. 11.2.9 RAN Disable transceptRanNodeDisableTable.transceptRanNodeDisableRanState This entry in the RAN Node MIB allows a given RAN to have all of its PAs disabled(*).

ADCP-75-192 • Issue 1 • December 2005 • Section 4: BTS Integration The BIM input balancing procedure is as follows: 1. Insert signals into the HP Attenuator at the recommended input level (composite). 2. If the input level is lower than the recommended value, adjust the transceptTenantMoreAttenTable.transceptTenantBimForwardAttenZOffset fields in the Tenant OAM MIB by a comparable amount. For example: If the PCS composite input is 44 dBm, enter a -30 into the transceptTenantMoreAttenTable.
ADCP-75-192 • Issue 1 • December 2005 • Section 4: BTS Integration 2.3 Functional RAN Call Verification At the completion of BTS integration, it is recommended that the coverage area be driven to insure all RANs are operational. The following procedure is recommended: 1. Place calls on all RF channels supported by targeted RAN sector 2. Ensure hand-offs between RANs and RAN to tower are functional.

ADCP-75-192 • Issue 1 • December 2005 • Section 5: Software Updates 3 UPGRADING EXISTING SYSTEM The most common upgrade scenario is one where an existing, fielded, operational system is having all of its CPUs upgraded to the next version of software. Some important notes regarding this type of upgrade: 3.
ADCP-75-192 • Issue 1 • December 2005 • Section 5: Software Updates • Test scripts being run to ensure that processes are running as expected. • If the autonomous actions taken by the upgrade executable discover that the upgrade was not successful, the upgrade executable will report this information in the log file located at /var/log/opencell-upgrade. Otherwise, a successful status message will be reported to that log.
ADCP-75-192 • Issue 1 • December 2005 • Section 5: Software Updates On the upgraded RAN CPU, verify PAs are functioning and power levels are as expected. Refer to the above "Preliminary Steps" section for details. 5 FAILED UPGRADES In the case of a failed upgrade, it will be desirable to attempt to return the target CPU to its previous revision by uninstalling the most recent software upgrade. This action will be accomplished with the use of a downgrade script that is installed as part of the upgrade.
ADCP-75-192 • Issue 1 • December 2005 • Section 5: Software Updates Upgrading a CPU does not require that a restore of the backed up files be performed unless a problem is encountered. Any data contained in the MIBmap files and any configuration data in the system configuration files will remain untouched through a software upgrade. The only time that backup data needs to be recovered is when an upgrade has failed and the CPU is being reverted to the previous version using the downgrade script.
ADCP-75-192 • Issue 1 • December 2005 • Section 5: Software Updates • address should be the IP address of a trap-sink (an SNMP manager that can receive traps); there can be any number of trap-sinks – simply enter one line per trap sink. • domain is that of the ADC system subnet on which nsupdate is being run. After completing the desired number of lines, finish by entering two blank lines and then a Ctrl-D.
ADCP-75-192 • Issue 1 • December 2005 • Section 5: Software Updates • In the event that a spare CPU cannot be updated because of the above restriction, the CPU will have to be upgraded on a standalone chassis that is not resident on the fielded system or be returned to the factory for upgrading. • It is NOT possible to update a spare Hub Master CPU while the fielded system's Hub Master is still installed, because two Hub Masters in the same domain will cause chaos on the network.

ADCP-75-192 • Issue 1 • December 2005 • Section 6: Autonomous Software Functionality 3 REVERSE AUTOMATIC GAIN CONTROL The Digivance CXD system autolimits any strong in-band signal which reaches the RAN at a peak input level of greater than -38 dBm relative to the antenna port. The process does this by monitoring A/D overflows and adding attenuation in the RDC when these overflow occur. “AGC events” are logged on the CPU running the RDC process. Attenuation is backed out as the signal strength subsides.
ADCP-75-192 • Issue 1 • December 2005 • Section 6: Autonomous Software Functionality 7.1 Noise Test The front-end noise will be monitored by reading the noise power value from the reverse channels in the RAN SIF module belonging to the tenant-sector being analyzed. The in-band noise power (N) and total signal power (S+N) will be measured and analyzed in the SIF using an FFT analysis, as follows: The RCM software will generate faults if the integrated power levels are below the specified thresholds. 7.

ADCP-75-192 • Issue 1 • December 2005 • Section 7: MIB Structure Each Hub/RAN node contains a Bus Scanner process whose responsibility is to discover the presence/absence of hardware modules and to start/stop HCP’s to manage those hardware modules. The Bus Scanner MIB reports the information defining the hardware “discovered” at that node. Each node contains a Network Node process to manage information about that CPU, where the interface is the Network Node MIB.
ADCP-75-192 • Issue 1 • December 2005 • Section 7: MIB Structure Tenant processing determines the location of its related nodes and hardware using a process called the Tenant Scan process that polls the Equipment MIB’s located at each node in the network. If the Equipment MIB indicates that there is hardware belonging to that tenant on that node, then the Tenant process in the Hubmaster will add that node to its "managed node" list.
