transceiver for transmission to the interconnected Remote Node(s).In the uplink path the Host Unit converts
a composite multi-band optical signal into independent RF signals for interconnection with the BTS receive
elements.
3.1.2 Interface with Cellular Phones
The mBSC Remote Node interfaces with the cellular phones through the service antennas. In the reverse
path, the Remote Node receives RF signals from cellular phones. In the forward path, the Remote Unit
transmits the RF signals to the cellular phones. A bi-directional antenna is connected to the mBSC Remote
Node to transmit and receive RF signals from the cellular phones.
3.1.3 Fiber Optic Transport
The Host Unit is connected to each Remote Node over a single optical fiber. The optical fibers must be
terminated withE2000/APC connectors for connection with the Host Unit and the Remote Node. For MIMO
operation a duplicate set of BTS interface, fiber transmission, and remote node equipment is required, along
with an additional optical fiber.
3.1.4 Powering
The Host Unit is powered by -48V DC which is supplied by either the equipment room power distribution
cabinet or an AC/DC converter. The Remote Node is powered by 110/220VAC, 50/60Hz power which is
supplied through a power supply distribution junction box.
3.1.5 Cooling
The Host Unit is cooled through cross-convection without fans.
The Remote Node contains multiple single-band Remote Units, which are cooled through continuous air
flow fans mounted on the top of each singe-band unit. A minimum of 200mm (7.87 inches) of clearance
space must be provided on both the top and the bottom sides of the Remote Node for air flow.
An alarm is provided that indicates if a high temperature condition occurs.
3.1.6 Fault Detection and Alarm Reporting
LED indicators are provided on the front panel of the Host Unit to indicate if the mBSC system is operating
as expected (normal) or if a fault is detected. In addition, normally open and closed alarm contacts (for both
major and minor alarms) are provided at the Host Unit for connection to a customer provided external alarm
system.
The mBSC system also includes a standalone (optional) Element Management System server, which
interconnects with each Host Unit in a multi-system deployment, and is used for system configuration, status
monitoring, and SNMP alarm reporting / management.
