Page 5: Description
Main input to one of the three outputs. Depending upon the type of data stream received the SSW3000C01 can function in two different modes: the first is valid for all DVB-ASI signals whereas the second can only be used for DVB-T type ASI streams. -
Page 6: Features
SNMP management and the ability to record events in a file including date and time information for further analysis. The SSW3000C01 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. -

Page 11: Installation
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified with a high degree of shielding for storage and transportation. The SSW3000C01 module is composed of two parts: one FRS3004P06 main board and one FRS3004P07 rear board. Both parts must be installed in a UR3000 or UR3100 mounting frame following the instructions in the corresponding section of this chapter. -
Page 12: Environmental Considerations
4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten. 5 - Insert the FRS3004P06 board (main board of the SSW3000C01 module) into the front of the mounting frame. The edges of the card slide into two plastic guides inside the mounting frame. - Page 13 Albalá Ingenieros | Manual SSW3000C01 Details for installation of the module in 3 RU mounting frames Details for installation of the module in 1 RU mounting frames...

Page 14: Interconnection
The following figure shows the SSW3000C01 module rear board connector layout. Rear view of the SSW3000C01 The SSW3000C01 module includes three DVB-ASI signal inputs (MAIN IN, RES IN and AUX IN) and three outputs (OUT1p, OUT2 and OUT3). The connector labeled OUT1p corresponds to the output signal that is protected by a bypass relay. -
Page 15: Electrical Dvb-Asi Video Connections
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest lengths because it is used to calculate the equalizers in the SSW3000C01. Cables carrying signal between the module and the devices should use single piece construction, avoiding spliced sections with double BNC female or barrel connectors. - Page 16 External fault indication for the Reserve signal source. INPUT FAIL AUX External fault indication for the Auxiliar signal source. OUT FAIL This signal is active when there is no output signal. This signal is active whenever the SSW3000c01 changes the ALARM selected output. Ground connection...

Page 17: Operation
Albalá Ingenieros | Manual SSW3000C01 4. OPERATION This section describes the significance of the front panel indicators of the SSW3000C01 module and their remote control and monitoring ability. 4.1. Front panel description The appearance of the front panel and the elements it contains are shown in the following illustration. - Page 18 Albalá Ingenieros | Manual SSW3000C01 In the INPUT FAIL box: MAIN, RESERVE, AUXILIAR: Red. These LEDs light up when no signal is present at the input, the TS sync is incorrect, the megaframe sync is incorrect or if the corresponding GPI failure input (INPUT FAIL MAIN, INPUT FAIL RES, INPUT FAIL AUX) is active.

Page 19: Functional Description
Recovery time for the switch can be programmed in order to prevent unnecessary switching after detection of a failure. By default this delay is 2.5 seconds. In addition, when a failure occurs at one input the SSW3000C01 will only switch to another input if a valid signal is detected at that input. - Page 20 Albalá Ingenieros | Manual SSW3000C01 Selection cycles in order through the Automatic, Semiautomatic and Manual modes. The selected operating mode is stored in non-volatile memory and will be restored in case of power supply failure.

Page 21: Module Remote Control And Supervision
Albalá Ingenieros | Manual SSW3000C01 4.3. Module remote control and supervision The SSW3000C01 can optionally be remotely controlled/supervised. In order to perform remote configuration and supervision of the module an optional TL3000 family remote communications controller must be installed in the mounting frame. -
