2.1 MC-Series High Power System Configuration
The MC-Series High Power system can be configured to have 1, 2 or 3 sectors. The
single-sector configuration can have up to 12 BRs. In multi-sector configurations, up to 12
BRs may be assigned per sector, providing a maximum capacity of 36 BRs in a 3-sector
configuration. As shipped, the MC-Series system is configured for 3 sectors.
Configurations are summarized in Table 2.

The MC-Series High Power system includes the following RadioFrame Networks
hardware:
• Power Distribution Unit (PDU) distributes DC power and provides overcurrent
protection to each component in the MC-Series system cabinet.
• Airlink/BTS Interface Chassis (ABIC) performs the digital receive and transmit
function for each RadioBlade
®
transceiver, provides the common timing source for
the RBS and is the interface to the iSC and routes Ethernet traffic for up to three
sectors.
• iDEN multi-channel RadioBlade (MCRB) transceivers insert into slots in the RBS;
each MCRB corresponds to up to six iDEN carriers in the 800 or 900 MHz band.
• Diversity RadioBlade Shelf (RBS) supports up to 36 BR, utilizing 6 Multi-Channel
RadioBlade transceivers, with an additional 6 MCRB for receive diversity.
• Rx Filter Shelf is equipped with two identical Rx paths per sector for receive
diversity.
• Tx Filter Shelf is a quadplexer for the Tx signal from both the 800 and 900 MHz
multi-channel power amplifiers (MCPAs) and the Rx signal from both the 800 and
900 MHz bands.
• Tx Sampling Ports, or sniffer ports, on the front of the Tx Filter Shelf allow the Tx
signals to be monitored without affecting normal operation.
• DC-DC Converter Bank supply +28 VDC to the six MCPAs.
The MC-Series system includes the following non-RadioFrame Networks hardware:
• iSC-3s: two integrated Site Controllers (iSC 3s) for redundancy
Caution!
Tx Sampling Ports may exceed +30 dBm peak power. This is composite output
power.
