Host Unit
The rack-mountable URH Host Unit is typically
located at a Base Station or a facility housing
a suite of Base Stations. On the forward path,
the Host Unit receives the RF signal from the
BTS and digitizes the designated RF band and
digitally transports it over single mode fiber or a
Millimeter Wave link to the Remote Unit. On the
reverse path, the Host Unit receives the digitized
RF signal from the remote unit and converts it
back to RF for the BTS.
The URH Host Unit is completely modular in
design, with all major modules; SeRF (Serial RF)
card, DART (Digital/Analog Radio Transceiver)
card, Power Supply, System board and Fan
being hot swappable.
The URH Host Unit supports up to eight DART
cards (supporting up to eight remote units) and
is capable of simulcasting signals up to as many
as eight Remote Units.
The Host Unit utilizes an embedded element
management system for system configuration
and network monitoring. The embedded EMS
collects alarm information from both the Host
and Remote Units. For multiple link deployments,
multiple Host Units can be networked together
at the same BTS site. Host Units can be daisy-
chained together to allow monitoring and
control of multiple Remote Units from a
single user interface.
In addition to sending alarm notifications to
the Element Management System (EMS) through
software, the URH Host Unit also features front
panel alarm reporting. LEDs on the front panel
of the Host Unit will change color depending
on the status of the unit. LED displays provide
information regarding the following items:
