7.2 Setting Channels
transceptTenantOAMTable.transceptTenantChannelXVal, where X = 1-8
Each Tenant sector in the Digivance CXD system can support from 1-8 channels. Each of
these eight (8) channel values can be individually set in the Tenant OAM MIB. The valid range
of values is based on the band and protocol selected for this tenant, per the specifications used
to define each protocol. Refer to Chapter 4, Section 2. In Composite Mode, only channel 1 is
active.
7.3 Setting Hub Measured Forward Gain
transceptTenantOAMTable.transceptTenantHubMeasuredForwardGain
This parameter is no longer used in the Digivance CXD system.
7.4 Setting RAN Measured Forward Gain
transceptTenantOAMTable.transceptTenantRanXMeasuredForwardGain, where X = 1-8
This parameter is no longer used in the Digivance CXD system.
7.5 Setting FSC Gain
transceptTenantMoreControlsTable.transceptTenantMoreControlsFscOutputGain
and
transceptTenantMoreControlsTable.transceptTenantMoreControlsFscOutputGainOverride
This feature allows the user to adjust FSC output gain outside of the default setting. The FSC
Output Gain value is in tenths of a dB, and represents the amount of loss from full scale
entered digitally in the forward path. For example, if a set of input signals had a peak to
average value higher than 12 dB, an operator may wish to remove 3 dB of gain to allow for the
extra peak power. The transceptTenantMoreControlsTable.FscOutputGain entry would be set
to a value of -30 in such a case. The default state of FscOutputGainOverride is “disabled”. In
its default state the system counts active FSC channels and governs FSC gain accordingly. To
begin using a desired override value, set FscOutputGainOverride to “enabled”.
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. Chapter 4, Section 3.
