2. Introduction 2. Introduction 2.1. Purpose Mobile telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area to carry voice and data traffic. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distributed antenna system (DAS).
3. Functional Description The unit utilizes a single fiber to support multiple bands in both the uplink and downlink directions. WDM (Wave Division Multiplex) filters are integrated in the optical modules. For the UL, a wavelength within 1546 nm – 1550 nm is used. For the DL, a wavelength of 1310 ±10 nm is used. The maximum optical output power for the UL and DL is 6.7 mW. 3.

5. Alarms 5. Alarms 5.1. Bite and Alarms The Built-In Test concept comprises the monitoring of the power supplies, the power amplifiers, fan units and the optical interface. All occurring alarms can be checked via software at the Master Unit. As soon as the software acknowledges a valid alarm, a message is transmitted to the Master Unit. If the reason for the alarm has been cleared or if the alarm should continue, a new alarm message will not be repeated.
5. Alarms 5.4. External Alarm Inputs and Outputs The eight-pin EXT ALARM IN/OUT connector supports two external alarm inputs and two external alarm outputs. Chapter 4.3.10 External alarm In / Out port includes the connector’s pin-out information and chapter 4.3.3 Connections identifies the connector’s location. The alarm outputs are realized with relays (switching capacity max. 60 VDC, max. 2 A, max 60 W). They can be used to monitor alarms with an external alarm indicator.
