PRELIMINARY
CDF/NECF
The CDF/NECF (Configuration Data File/Network Element
Configuration File) contains information that defines the BTS and data
used to download files to the devices. A CDF/NECF File must be placed
in the applicable BTS Folder before the LMF can be used to log into that
BTS.
CDF/NECF Files are normally obtained from the CBSC using a Floppy
Disk. A File Transfer Protocol (FTP) Method can be used if the LMF
Computer has that capability. Refer to the WinLMF On-Line Help
SR2.16.x for more information.
The CDF/NECF includes the following information:
S Download Instructions and Protocol
S Site–specific Equipage Information
S SCCP Cage Allocation Plan
– BBX Equipage (based on Cell Site Type) including IS–95A/B or
CDMA2000 1X Capability and Redundancy
– CSM Equipage including Redundancy
– Multi–Channel Card 24E, 8E, or –1X (MCC24E, MCC8E, or
MCC–1X) Channel Element Allocation Plan. This plan identifies
how the SCCP Cage is configured, and how the Paging,
Synchronization, Traffic, and Access Channel Elements (and
associated Gain Values) are assigned among the (up to 4)
MCC24Es, MCC8Es, and/or MCC–1Xs in the SCCP Cage.
S Effective Rated Power (ERP) Table for all TX Channels to Antennas
respectively. Motorola System Engineering specifies the ERP of a
Transmit Antenna based on site geography, antenna placement, and
government regulations.
Working from this ERP Requirement, Antenna Gain and Antenna
Feed Line Loss can be combined to calculate the required Transmit
Power at the BTS Frame Antenna Connections. The corresponding
BBX Output Power required to achieve that Power Level on any
channel/sector can then be determined based on Bay Level Offset
(BLO) Data established during the Optimization Process.
Refer to Figure 3-1 and the LMF Help Function On–line
Documentation for additional information on the layout of
the LMF Directory Structure (including CDF/NECF File
locations and formats).
NOTE
BTS System Software
Download
BTS System Software must be successfully downloaded to the BTS
Processor Cards before Optimization can be performed. BTS Operating
Code is loaded from the LMF Computer.
