One ASI output port is available for monitoring. Any of the four COFDM inputs can be
copied to the ASI output without affecting the services in use. The ASI connector is a
75Ω BNC connector.
The COFDM module is equipped with an electrical (RJ45) connector for management.
The connection supports the automatic sensing of an 10/100/1000 Mbit connection.
For a 1000 Mbit connection, the Ethernet cable must be a category 6 cable.
3.3.6 QAM Input
Each QAM input module has one 75Ω F connector and can tune up to 4 independent
frequencies.
One ASI output port is available for monitoring. Any of the four QAM inputs can be
copied to the ASI output without affecting the services in use. The ASI connector is a
75Ω BNC connector.
The QAM module is equipped with an electrical (RJ45) connector for management.
The connection supports auto sensing of a 10/100/1000 Mbit connection. For a 1000
Mbit connection, the Ethernet cable must be a category 6 cable.
3.4 Connecting Output Signals
3.4.1 IP Output
The IP output card is equipped with both an electrical (RJ45) connector and one
optical (via SFP module) for data. The RJ45 connector marked “control” is not in use.
The Ethernet copper connection supports auto sensing of a 10/100/1000 Mbit
connection. For a 1000 Mbit connection, the Ethernet cable must be a category 6
cable.
Both the electrical and the SFP connectors for data have the same IP address and can
consequently not be used simultaneously. Both inputs are automatically activated.
The first port activated (establishing a link towards the router) will be the active port.
To activate the other port, the cable on the active port must first be removed.
3.4.2 ASI Output
Each ASI output module has 4 independent ASI outputs. The ASI connector is a 75Ω
BNC connector.
3.4.3 QAM Output
Each QAM output module has one 75Ω F connector which carries up to 8 frequencies.
Revision 1 of the QAM card has an external Ethernet cable between the IP-output card
and the QAM modulator card, both the transportstream and control of the modulator
is done via this Ethernet cable.
