RFDS Set–up and Calibration

RFDS Description

NOTE

The RFDS is not available for the –48 V BTS at the time of this

publication.

The optional RFDS performs RF tests of the site from the CBSC or from

an LMF. The RFDS consists of the following elements:

S Antenna Select Unit (ASU)

S Fixed Wireless Terminal Interface Card (FWTIC)

S Subscriber Unit Assembly (SUA)

For complete information regarding the RFDS, refer to the CDMA

CDMA RFDS Hardware Installation; 68P64113A93, CDMA RFDS

User’s Guide; 68P64114A51, and the LMF Help function on–line

documentation.

RFDS Parameter Settings

The bts–#.cdf file includes RFDS parameter settings that must match the

installed RFDS equipment. The paragraphs below describe the editable

parameters and their defaults. Table 3-42 explains how to edit the

parameter settings.

S RfdsEquip – valid inputs are 0 through 2.

0 = (default) RFDS is not equipped

1 = Non-Cobra/Patzer box RFDS

2 = Cobra RFDS

S TsuEquip – valid inputs are 0 or 1

0 = (default) TSU not equipped

1 = TSU is equipped in the system

S MC1....4 – valid inputs are 0 or 1

0 = (default) Not equipped

1 = Multicouplers equipped in RFDS system

(9600 system RFDS only)

S Asu1/2Equip – valid inputs are 0 or 1

0 = (default) Not equipped

1 = Equipped

S TestOrigDN – valid inputs are ’’’ (default) or a numerical string up to

15 characters. (This is the phone number the RFDS dials when

originating a call. A dummy number needs to be set up by the switch,

and is to be used in this field.)

NOTE

Any text editor may be used to open the bts–#.cdf file to verify,

view, or modify data. Because the bts–#.cdf file is generated on

a Unix system, a more sophisticated editor, such as MicroSoft

WordPad, will display file content in a more easily–read format

than many simple text editors.
