1. DESCRIPTION
1.1. The DSW3000C03
The DSW3000C03 automated switch is a selector for digital streams in ITU-T G.703
format at 2048kbit/s that operates depending upon the presence of signals at its inputs
and the status of its GPI connectors, all based upon a set of priorities.
In order to detect a lack of signal at the inputs, the DSW3000C03 includes Loss of Signal
detectors (LOS) and Alarm Indicator Signals (AIS) for each input.
The DSW3000C03 provides three inputs labeled Main, Reserve and Auxiliary. The
selected input at any given time is distributed to three outputs. In the case of a power
supply failure, a bypass is performed from the Main input to one of the three outputs.
The DSW3000C03 provides three operating modes: selection of the input can be
Automatic, Semiautomatic or Manual. Any change in the input selected is announced via
an LED and an audible beep.
It is possible to monitor the DSW3000C03 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The DSW3000C03 is a TL3000 terminal line module and can be housed in a three rack
unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.
The DSW3000 family includes several automated switches for different signal types. The
following variations exist:
• DSW3000C01: Automated switch for DVB-ASI and SD-SDI signals.
• DSW3000C02: Automated switch for ITU-T G.703 signals at 155,520kbit/s (STM-1).
• DSW3000C03: Automated switch for ITU-T G.703 signals at 2048kbit/s (E1).
• DSW3000C04: Automated switch for ITU-T G.703 signals at 34,368kbit/s (E3).
• DSW3000C05: Automated switch for ITU-T G.703 signals at 44,736kbit/s (DS3).
