Description 
10Base2 
 
10Base2 is also known as Thin Ethernet. 10Base2 cables support 
transmission speeds up to 10 Mbits/second. The maximum distance per 
segment is 185 meters. 
10BaseT 
 
10BaseT is the most common form of Ethernet cabling. The cable is 
thinner and more flexible than the coaxial cable used for the 10Base2 
standard. 10BaseT is also known as unshielded twisted-pair (UTP). 
10BaseT cables support speeds up to 10 Mbps. The maximum distance 
per segment is 500 meters. 
AIC 
Airlink Interface Chassis 
The central baseband processing unit for the MC-Series System, 
providing Rx/Tx airlink traffic to/from RBSs. 
BIC 
BTS Interface Chassis 
The central network processing unit for the MC-Series System. Also 
central management entity for managing configuration and User 
Information. 
BPC 
BTS Processing Cards 
Interface to the BIC CRIC for the bi-directional transfer of voice I and Q 
samples to/from RBS. 
BPC+SPAM 
BPC+SPAM 
Interface to the AIC CRIC for the control of RBS components and the 
transfer of voice I/Q samples to/from RBS. 
CRIC 
Common RadioFrame 
Interface Card 
In the BIC, provides Ethernet switching to/from the AIC, and serves as 
the primary controller of the BPCs. In the AIC, provides Ethernet 
switching to/from the AIC and the RBS, and serves as the primary 
controller of the BPC+SPAMs. 
CRTC 
Coax-to-RJ45 
Transceiver Card 
Provides 10base2 (coaxial television) conversion to 10baseT (RJ45). 
This card connects the 10base2 cable coming from the iSC to Port 1 of 
the BIC. 
CSU 
Channel Service Unit 
The CSU provides the T1 connection between the iSC-3 and the 
telephone company that provides the T1 line. 
EAS 
Environmental Alarm 
System 
The EAS provides a central location for site alarm signal processing. 
The EAS monitors environmental conditions of the site, including power, 
smoke alarms, and intrusion alarms. 
EIA 
Electronic Industries 
Alliance 
The EIA organization establishes electronic interface standards. 
ERTM 
Ethernet Rear Transition 
Module 
In the BIC, provides timing and data to the AIC. In the AIC, provides 
timing and data to the RBS. 
ESD 
Electrostatic Discharge 
The dissipation of electricity, commonly known as a shock. ESD can 
destroy semiconductor products, even when the discharge is too small 
to be felt. 
FRU 
Field Replaceable Unit 
Any unit (module, board, or card) that can be “hot-swapped”, that is, 
replaced with another unit while the power is connected to the item 
housing the unit. 
GPS 
Global Positioning 
System 
A system that uses geostationary satellites to triangulate the position of 
a GPS receiver located on earth. 
iDEN 
integrated Digital 
Enhanced Network 
Motorola's proprietary digital technology that combines the capabilities 
of a standard analog dispatch system with that of a cellular interconnect 
system. iDEN uses an advanced proprietary modulation technology 
consisting of a speech compression scheme enabling three or six 
communication paths over a single 25 kHz RF channel.
