Term or Abbreviation Definition
CRMS Cellular Radio Monitoring System
circuit backhaul Conventional, non–Internet Protocol (IP) backhaul between the BTS and the
Central Base Station Controller (CBSC) transcoder (XC) which carries IS–95A/B
traffic.
duplex router See redundant router
ESM Ethernet Surge Module
external BTS router MWR 1900 or MWR 1941 BTS routers mounted outside the C–CCP or SCCP
cage of a packet BTS.
FE Fast Ethernet. 100base–T mode of 10/100base–T Ethernet used for transmitting
packetized control and bearer traffic between the BTS router group and GLI3
cards in the BTS.
GLI3 Third generation Group Line Interface card. Replaces GLI2 cards in a BTS when
upgrading to packet backhaul capability under Software Release 2.16.1.x.
Provides all the functionality of GLI2 cards plus additional capabilities needed for
packet backhaul. GLI3 cards may only be installed in BSSs operating with
Software Release 2.16.1.x software.
high availability BTS
router
See redundant router.
IBR Integrated BTS Router; see integrated BTS router
Integrated BTS Router A GLI3 card loaded with bootROM code which allows the card’s controller for
Concentration Interface Highway (CHI) bus 2 to function as a router for packet
traffic for the BTS. Employing IBRs permits converting a BTS to packet backhaul
operation without using an external BTS router group. IBRs can operate as
non–redundant or redundant BTS routers, but their employment limits BTS span
capacity to one span as opposed to four spans for external BTS routers.
IOS Internetwork Operating System. Operating system software used by the external
BTS routers.
minimum standard
configuration
The initial minimum configuration data which must be loaded into a BTS router
to enable it to communicate on the network. This standard “canned configuration”
is generated by a script included in the R16.1 software load for the
OMC–R/CBSC. Separate configuration files for the primary BTS router on each
FE LAN at a site is created by the script and can be copied to the Compact Flash
(CF) memory card containing the IOS for BTS routers. Once the CF card with the
IOS and minimum standard configuration is installed, the BTS router can
communicate with the OMC–IP and the full, site–specific router configuration file
can be downloaded from the Mobile Wireless Center to the router. Different
configuration files are required for circuit and packet backhaul operation.
mixed backhaul See split backhaul.
