2.2 RadioFrame Networks Hardware
RadioFrame Networks hardware receives layer-3 control messages (control, voice,
packet data, SNMP, etc.) from the iSC and converts them into layer 2 PDUs (Protocol
Data Units) that are sent every 15 ms (received every 7.5 ms). Then the AIC converts the
layer-2 PDUs into raw layer-1 Baseband I/Q samples that are sent/received every 7.5 ms.

2.2.1 Air/BTS Interface Chassis (ABIC)
The BTS Interface Chassis (BIC) interfaces to the iSC and provides all Base Radio (BR)
management functionality, including timing, converts iSC layer 3 messaging to layer 2
packets, and converts 1PPS 5 MHz clock to packet-delivered timing. Within the BIC
chassis are four assemblies (see the following illustrations):

chassis are four assemblies (see the following illustrations):
• BIC Common RadioFrame Interface Card (CRIC)
• BTS Processing Card (BPC)—up to three BPCs per system, one BPC per sector,
• BTS Processing Card (BPC)—up to three BPCs per system, one BPC per sector,
deployed in front slots 2, 3 and 4
• Ethernet Rear Transition Module (ERTM)
• Coax-to-RMII Transceiver Card (CRTC) (2) deployed in rear slots 3 and 5
• Coax-to-RMII Transceiver Card (CRTC) (2) deployed in rear slots 3 and 5

The Airlink Interface Chassis (AIC) provides layer-1 and layer-2 processing of call data,
including routing of packet data to RadioBlade transceivers in RBS, as well as timing to
the RBS. Within the AIC chassis are three assemblies:

• AIC Common RadioFrame Interface Card (CRIC)
• BTS Processing Card + Signal Processing Array Module (BPC+SPAM)—three
• BTS Processing Card + Signal Processing Array Module (BPC+SPAM)—three
BPC+SPAM per AIC in front slots 2, 3 and 4
• Ethernet Rear Transition Module (ERTM)
