RFDS Description

The optional RFDS is used to perform RF tests of the site from the

CBSC or from the LMF. The RFDS contains the following FRUs:

 Antenna Select Unit (ASU)

 Fixed Wireless Terminal Interface Card (FWTIC)

 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 Parameters

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 3-46 explains how to edit the

parameter settings.

 RfdsEquip – valid inputs are 0 through 2.

0 = (default) RFDS is not equipped

1 = Non-Cobra/Patzer box RFDS

2 = Cobra RFDS

 TsuEquip – valid inputs are 0 or 1

0 = (default) TSU not equipped

1 = TSU is equipped in the system

 MC1....4 – valid inputs are 0 or 1

0 = (default) Not equipped

1 = Multicouplers equipped in RFDS system

(SC9600 internal RFDS only)

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

0 = (default) Not equipped

1 = Equipped

 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.)

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.
