2.2.2 Airlink Interface Chassis (AIC)
2.2.2.1 AIC
CRIC
The AIC Common RadioFrame Interface Card (CRIC) provides the Ethernet switch fabric
to route packets to/from the RBS. The AIC CRIC hosts a microprocessor as the primary
controller of BPC+SPAMs. The AIC CRIC has a serial port for local serial access, and
eight 10/100BaseT Ethernet ports that are currently not used.

2.2.2.2 BPC+SPAM
BTS Processing Card + Signal Processing Array Module (BPC+SPAMs) are DSP
modules that control the transfer of voice I/Q samples to/from the RBS. BPC+SPAMs
perform all necessary functions of radio link formatting, coding, timing, error control and
framing: Voice Control Procedure (VCP), Associated Control Procedure (ACP), Slot
Interchange Procedure (SIP) and Random Access Protocol (RAP).

2.2.2.3 ERTM
The Ethernet Rear Transition Module (ERTM), located in a rear slot of the AIC, interfaces
to the CRIC via eight RMII ports in the chassis midplane. The ERTM provides Ethernet
connectivity between the AIC and RBS.

2.2.3 RadioBlade Shelf (RBS)
The RadioBlade Shelf (RBS) houses the iDEN 2-port RadioBlade transceivers, the
RadioBlade transceiver “backplane” and RF combiner and splitter assemblies. The whole
assembly is housed in a pullout shelf to facilitate field replacement of the RadioBlade
transceivers.
