2.1 MC-Series System Configuration
The MC-Series System can be configured to have 1, 2, or 3 sectors. The single sector, or omni
configuration can have up to 20 BRs. In multi-sector configurations, the BRs must be assigned to
sectors in groups of 8. For a 3-sector system the maximum number of BRs per sector is 8. For a
2-sector configuration one of the sectors can have up to 16 BRs, while the other sector can have
up to 8, providing a maximum capacity of 24 BRs in a 2- or 3-sector configuration.
The MC-Series System includes the following RadioFrame Networks hardware:
• BTS Interface Chassis (BIC) is the interface to the iSC and routes Ethernet traffic for up to
three sectors.
• Airlink Interface Chassis (AIC) performs the digital receive and transmit function for each
RadioBlade (RB) and provides the common timing source for each RBS.
• RadioBlade Shelf (RBS) enables up to 24 RadioBlade
®
transceivers. A second RBS is
required to provide diversity through “receive only” RadioBlade transceivers.
• iDEN 2-port RadioBlade transceivers (RBs) insert into slots in the RBS; each RB corresponds
to one iDEN BR.
• RF Shelf provides Rx-Tx amplification, filtering, and distribution between the RBSs and
external equipment.
• Power Distribution Unit (PDU) distributes DC power and provides overcurrent protection to
each component in the MC-Series System cabinet.
The MC-Series System includes the following non-RadioFrame Networks hardware:
• ISC-3s: two integrated Site Controllers (iSC 3s) for redundancy
• Environmental Alarm System (EAS)
provides additional external alarming as required.
• Channel Service Unit (CSU) single-rack unit, high multi-purpose cross-connect, with the
ability to aggregate multiple types of traffic onto a single T1 for backhaul to the MSO.
• DC power source.
