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. There is one RAN Gain offset parameter in the Tenant OAM MIB
for each RAN in a tenant simulcast group. The valid range of values for these parameters is -
120 to +80, which is -12 to +8 dB in 1/10 dB units.
Note: It is possible to overdrive the forward path, which will cause the PA to fault and shut down.
7.7 Setting Reverse Gain
transceptTenantOAMTable.transceptTenantReverseGain
The Reverse Gain parameter in the Tenant OAM MIB allows the Reverse Gain Target to be
set. This value sets the gain for the entire reverse path. The valid range of values for this
parameter is -100 to +100, which is -10 to +10 dB in 1/10 dB units. The system assumes a 20
dB pad between the BIM and the BTS. If the 20 dB pad is not used then the +/- 10 dB gain
setting maps to +10 to +30 dB of gain.
7.8 Setting Reverse Cable Loss
transceptTenantOAMTable.transceptTenantReverseCableLoss
Reverse Cable Loss is a parameter in the Tenant OAM MIB to allow the signal loss due to
cabling between the base stations and the Digivance CXD system to be factored into the
reverse gain management processing. This parameter has a valid range of values of 0 to 50,
which is 0 to +5 dB in 1/10 dB units. The maximum cable loss between the BTS and the BIM
is 5 dB.
7.9 Using Tenant Reset
transceptTenantOAMTable.transceptTenantReset
Tenant Reset is a parameter in the Tenant OAM MIB that will allow all of the hardware that is
associated with a tenant to be reset. This functionality is not currently supported in the
Digivance CXD software.
7.10 Enabling FGC / RGC
transceptTenantOAMTable.transceptTenantForwardAGCDisable
and
transceptTenantOAMTable.transceptTenantReverseAGCDisable
The Forward and Reverse Gain/Continuity Management processes can be disabled on a per tenant
basis using the enable/disable parameters in the Tenant MIB. These MIB fields are enumerated
types with values "Enabled" = 0, and "Disabled" = 1. The reason for the inverse boolean logic is so
that the desired default values are set to be zero, which is the MIB default value.
