2.2.4.3
Combined RadioBlade Transceivers in an RBS
The MCRB allows up to 6 BRs to be assigned to a single physical RadioBlade transceiver
with a requirement applied that all carriers need to be within the same 1.25 MHz band.
Because of this requirement, all frequencies need to be known prior to the programming
of the MCRB. To accommodate this, all BRs set up in the iDEN configuration page will
register with the network to get assigned frequencies. Once the frequencies are known,
and the available HW resources are known, the carriers are assigned to the MCRBs and
single-channel RadioBlade transceivers by the following rules:

1) Any 900 MHz BRs will be assigned to an MCRB.
2) The largest group of carriers which fall within the 1.25 MHz band is assigned to the MCRB if
2) The largest group of carriers which fall within the 1.25 MHz band is assigned to the MCRB if
one is available. (Note: This process repeats until there are no remaining unassigned MCRBs.)
3) Any carriers that remain unassigned are assigned to single-channel RadioBlade transceivers.
4) If any carriers are still unassigned, an alarm is sent to the OMC.

2.2.5 High Power Dual-Band RF Shelf
The MC-Series system provides one RF shelf per sector. The RF shelf contains
amplifiers, filters, combiners, redundant DC-DC converters and fans to provide cooling to
the power amplifiers (PAs).
