The Forward and Reverse Delay Compensation processes, which balance the signal delay in a
simulcast group, can be enabled/disabled using the associated objects in the Tenant OAM 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.
3.4.13 Forward/Reverse Target Delay
transceptTenantTargetDelayTable.transceptTenantForwardTargetDelay
and
transceptTenantTargetDelayTable.transceptTenantReverseTargetDelay
The Forward/Reverse Target delays can be adjusted using the Tenant Forward/Reverse Target
Delay entries in the Tenant OAM MIB. The valid range of values for the Forward/Reverse target
Delay is 12,000 to 195,000 ns with a default of 100,000 ns.
3.4.14 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 objects 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. 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. For example:
To disable RAN 3 in a simulcast, set transceptTenantOAMTable.transceptTenantRANDisable3
to a “1” (disabled).
3.4.15 FSC Atttenuator Offsets
transceptTenantCalTable.transceptTenantFscAttenX
If not using Composite Mode, there is a step during Forward RF Path Balancing that requires
that the FSC Digital path attenuators be adjusted. These adjustments need to be made in the
Tenant OAM MIB in the FSC Attenuator Offset fields, of which there is one per channel in the
Tenant OAM MIB with the naming convention. The values that are set in the Tenant OAM MIB
will be pushed down to the appropriate FSC MIB Attenuator fields. Doing these settings in the
Tenant OAM MIB will allow consistency with the maintenance of configuration data.
