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.
