Acronym Term 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.
