a 0.5dB hysteresis margin).
The Uplink AGC operating region continues through higher uplink signal levels, until the AGC/overload
attenuator in the Remote Unit has run out of range. This is typically 5 to 20 dB of active AGC range.
At that point the uplink will be switched off to protect the system.
The Uplink AGC threshold for each RU does not directly affect the uplink gain, though in some cases
where the target Uplink gains and RU AGC levels are high, the system may warn that the uplink gain
needs to be limited when a new configuration is Validated/Applied, to avoid over-driving the Service
Module outputs.
The user can Enable or Disable the power amplifier and the LNA in the Remote Unit (Radio State).
All Remote Units can be conveniently enabled/disabled and set to the same default settings by selecting
from the relevant drop-down at the top of the list of RUs, and clicking the adjacent “Set” button.
10.4 System Status
The System Status page displays the topology of the Distributed Antenna System and the status/details
of all the individual elements comprising the DAS. Configuration changes must be made via the System
Setup page.
10.4.1 System Status Topology Tree and Modules
The following color coding is used for Units in the Topology Tree and any associated Modules:
• Green Icon – Functional
• Amber Icon – Hardware or Service Warning
• Red Icon – Loss of Service / Fault
• Black Icon – Disconnected link (to RU or optical module)
• Grey Icon & Black Numeric – Module disabled by User
• Grey Icon & Grey Numeric – Empty slot or Module not present
• Blue Icon – Indicates an Optical Loop Back (OLB) present
The Icons alongside each Unit in the Topology Tree show the status of its Optical Links:
• Green Icon – Optical loss within usable range
• Amber Icon – Optical loss at upper end of usable range – clean connections
• Red Icon – Optical loss out of specification – link must be improved
• Blue Icon – Optical loss not yet measured
10.4.2 Unit and Module Details
When the System Status tree is expanded, it is possible to click on each item in the tree to see its
current properties, such as measured power levels and alarm status. All discovered Units and the
Modules in the Primary Hub are displayed:
• Primary Hub (PH): Head-end of DAS, interfacing Services to SHs and/or RUs
