Introduction to the EQ8096
1.2.6 Modulation and Up-conversion
Each modulator card of the EQ8096 supports the simultaneous generation of up to
12QAM channels via 3 F-type connectors. Each channel shares the same annex,
QAM mode and symbol-rate. Each output connector provides up to four adjacent
QAM channels.
For redundancy, each Modulator assembly supports hot swap. This feature is
detailed in Section 6.5.4, Preventive Maintenance and Fault-finding
1.2.7 Control and Monitoring
The EQ8096 supports a dedicated dual redundant Ethernet control port for the
control and monitoring of the unit. It can be controlled using either the built-in Web
server, which can be accessed via a standard web browser application, or via
SNMP. The Web interface allows the user full control of the unit’s configuration and
can also be used to obtain the current status of the unit.
The SNMP interface has support for alarm generation via SNMP traps. These traps
are configured via the Web interface. All user-controlled parameters are stored in
non-volatile memory and are restored on power up.
1.2.8 DVB-CA
This is an optional feature that can selectively scramble services of one or more
MPEG Transport Streams, controlled by an external third-party DVB-CA (Simulcrypt
compliant) system or using a stand-alone XML configuration file.
Communications to the CA system (EIS, ECMG and EMMG communication) are via
a dedicated dual redundant CA port.
1.3 Output Channel Mappings
1.3.1 Channel Mappings
The EQ8096 supports 96 total QAM channels, spread across a maximum of 8
Output cards. Each Output card supports a maximum of 12-channels.
The EQ8096 can operate in 4 distinct mapping modes, depending on the installation
requirements:
• Standard (direct) mapping
• Distributed (striped) mapping
• ‘6 Card’ mapping
• Single 1G Input mapping
