The Transport Module is visually similar to an Optical Module, but with internal hardware differences to
permit it to also perform the job of a Service Module. It is not interchangeable with an Optical Module.
A pair of Transport Modules is required to create a UniTransport link.
From a software perspective, any permutation of Service Module and Transport
Module may be fitted to the input slots of a Primary Hub, and any permutation of
Optical Module and Transport Module may be fitted to the output slots of a
UniTransport Hub.
From an RF perspective, note that the uplink performance as seen by any one
Base-Station is inversely proportional to the number of Remote Units that it is
connected to a UniTransport system needs to be designed and planned just
like any other DAS.
12.2 Configuration of UniTransport Hub
As with all Primary Hubs, up to 4 Services are connected through Service
Modules in the rear slots and their levels are adjusted according to the required relative levels and the
expected absolute levels. The UniTransport Hub is capable of grouping the input services through a
switch matrix and routing some or all to the outgoing Transport Modules in the front Optical slots. These
controls on the System Setup page are configured as normal.
The right-hand side of the System Setup view shows a list of connected downstream Primary Hubs, as
well as the usual list of Remote Units, if any are connected.
The key difference between a directly-connected Remote Unit and one connected via a downstream
Primary Hub is that the gain budget is now split into two parts. There might be a need for 20dB gain
between a service input and each Remote Unit output, and to reach the overall link target, both the
UniTransport Hub and the downstream Primary Hub need gain settings that add up to 20dB. To make
it as simple as possible, the hub software calculates all the settings from your input of the power level
that is to be sent over the fiber.
