Anleitung Zusammenfassung
The MIB fields are: transceptBtsConnectionTable.transceptBtsConnectionBimI2cBus and Page 25 © 2007, ADC Telecommunications, Inc. ADCP-75-192 • Issue 2 • June 2007 transceptBtsConnectionTable.transceptBtsConnectionBimI2cSlot • The BIM module belonging to this tenant must have RF connections to one FBHDC modules. Select the I2C Bus of the FBHDC module that matches the BIM I2C bus value. Set the FBHDC I2C slot value to “1”. The FBHDCs belonging to a single tenant (i.e. having RF connections to the same BIM module) should be co-located in the RF chassis, with an FSC and HUC modules separating them. The MIB fields are: transceptBtsConnectionTable.transceptBtsConnectionHdcXI2cBus and transceptBtsConnectionTable.transceptBtsConnectionHdcXI2cSlot, where X = 1 or 2. • The FBHDC module belonging to this tenant is cabled to a single FSC module, which is located in a chassis slot directly above the tenant's FBHDC module. Select the I2C Bus and Slot of the FSC module to that of its corresponding BIM. Set the I2C slot value to “2”. The MIB fields are: transceptBtsConnectionTable.transceptBtsConnectionFscI2cBus and transceptBtsConnectionTable.transceptBtsConnectionFscI2cSlot • When using receive diversity, the BIM module belonging to this tenant must have two RF connections to a single HUC module. One for primary reverse signals and the other for diversity reverse signals. Without receive diversity, only the Primary HUC output need be cabled to the BIM. The location of the HUC module for this tenant must be co-located with the FBHDC and FSC modules belonging to this tenant. Set the I2C Bus of the HUC module to that of its corresponding BIM. Set the I2C slot value to “0”. The MIB fields are: transceptBtsConnectionTable.transceptBtsConnectionHucI2cBus and transceptBtsConnectionTable.transceptBtsConnectionHucI2cSlot. Once the above I2C addresses are set for the tenant being configured, the Hub Config Process will push this information down to the Hub RF Connection MIB on the node/CPU that manages the tenant RF hardware. Clearing Tenants It is possible to “de-configure” a tenant, which will clear all of the configuration information described above, by setting the Clear field in the BTS Connection MIB for this tenant to a value of '1'. This will allow the configuration process to be restarted from the beginning. The MIB field is: transceptBtsConnectionTable.transceptBtsConnectionClear Page 26 © 2007, ADC Telecommunications, Inc. ADCP-75-192 • Issue 2 • June 2007 3.3.2.7 HUC Invalid Config The BTS Connection MIB contains a read-only field that reports the state of the HUC Invalid Configuration fault field. This information will allow the person configuring the system to know that the tenant has been completely and correctly configured - this is known when the value in this field is reported as “No Fault” or '0'. The MIB field is: transceptBtsConnectionTable.transceptBtsConnectionHucInvalidConnection. 3.3.2.8 Composite Mode The Digivance CXD/NXD 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 7. Output Signal Strength INPUT (RMS AT FBHDC INPUT) CELL/SMR OUTPUT(RMS AT ANTENNA PORT) PCS OUTPUT (RMS AT ANTENNA PORT) -2 dBm +40 dBm +43 dBm -4 dBm +38 dBm +41 dBm -7 dBm +35 dBm +38 dBm As the protocol is irrelevant in this mode, the default protocol is “none”. In addition, only a single FSC channel is activated. To sum multiple FSC channels, set the composite mode entry to “disabled” and follow instructions on setting channels in Section 7 Tenant Configuration. The MIB field is: transceptBtsConnectionForwardGainTable.transceptBtsConnectionForwardGainCompositeMo deFlag 3.3.2.9 Power Attenuator IDs The BTS Connection MIB contains two fields that allow the external power attenuators to be identified. The attenuators reside in a shelf at the top of each rack. To configure these two MIB fields, the nomenclature described in 3-1. HUB Rack Numbering, should be used. This dictates that the attenuators should be given names that indicate the shelf number and the location on the shelf. For a given tenant, the two power attenuators must be configured with unique IDs, where the allowable values are strings of length 1-16. If both attenuators are configured, then software will configure the BIM to operate in duplexed mode, otherwise, software will configure the BIM to operate in non-duplex mode. The MIB fields are: transceptBtsControlParamsTable.transceptBtsControlParamsPowerAttenXLoc, where X = 1 or 2. Page 27 © 2007, ADC Telecommunications, Inc. ADCP-75-192 • Issue 2 • June 2007 3.4 Tenant Configuration The Tenant Operations Management and Maintenance (OAM) MIB is the primary interface for configuring the operating objects of tenants in the Digivance CXD/NXD system. The Tenant OAM...
