CDMA Operating Frequency Programming Information

Introduction

Programming of each of the BTS BBX synthesizers is performed by the

BTS GLI2s via the Concentration Highway Interface (CHI) bus. This

programming data determines the transmit and receive transceiver

operating frequencies (channels) for each BBX.

Figure D-1 shows the valid channels for the North American PCS

1900 MHz frequency spectrum. There are 10 CDMA wireline or

non-wireline band channels used in a CDMA system (unique per

customer operating system).
