G3L-1900-31/G3L-1900-31-A Operation Manual Section 1 General Description 1-1 Introduction This manual contains information and procedures for the operation of the model G3L-1900-31 and G3L-1900-31-A Wideband (WCDMA) Multi-Carrier Power Amplifier (MCPA). The manual is organized into the following sections and appendix.
G3L-1900-31/G3L-1900-31-A Operation Manual 1-3.3 TLCI Bus Communications The purpose of the TCLI bus is to provide a communications interface between the power amplifier and base station. The bus is connected from the base station subrack to the X3 connector located on the power amplifier rear panel as shown in figure 1-1. Table 1-2 lists the signal names and descriptions for each pin of the 24-pin connector.
G3L-1900-31/G3L-1900-31-A Operation Manual 1-4 Alarms The WPA generates the following alarms and communicates then to the base station via the TLIC bus: · VSWR · Gain · Temperature · Over-Drive · Power Supply · Linearization The base station is able to query the current alarm status from the WPA. Fault status is cleared at unit reset which means that any alarm detected after reset is reported to the base station. The alarm status always represents existing conditions. 1-4.
