1.1.1.18 DVB ASI input
Inputs connected to the DVB ASI ports should be on DVB compliant
transport streams in asynchronous serial format.
Each DVB ASI connector has two LEDs associated with it; ASI Rx and
Active. Both LEDs are lit when the ASI input is enabled and a DVB ASI
stream is connected to the port. If the input is enabled, but no valid
stream is connected to the port, only the ASI Rx LED is lit. If the ASI
input is disabled none of the LEDs are lit.
1.1.1.19 DVB ASI output
When in IP receive mode, the ASI port will provide a DVB compliant
transport stream. When no stream is received over the IP network, the
output will be idle characters. If a stream is received, the output will be
a combination of MPEG-2 transport stream data bytes and idle
characters.
The ASI Rx is always unlit when the ASI port is configured as an ASI
output. The LED, designated Active, is lit when the output is enabled
and unlit when the output is disabled.
2.4.3 Ethernet data port
The Ethernet port provides an electrical Ethernet data port. The default
interface is 100Base-T. As an option, the port can be operated as
1000Base-T. In this case the port can auto sense between 100 and
1000 Mbits/s. The operator is able to force the interface speed to fixed
100Mbit/s or fixed 1000Mbit/s. This is useful to minimize the
synchronization time when reconnecting signal cables.
Table 6. Ethernet data port
Two LEDs are associated with the Ethernet data port.
For flexibility, the ASI-IP-GTW provides an optional Small Form-Factor
Pluggable (SFP) slot to carry a copper or optical SFP, allowing
customers to use different SFPs for special distance, cost, existing
infrastructure, and future expansion requirements. The ASI-IP-GTW is
prepared for electrical (1000Base-T) or optical 1000BASE-SX and
1000BASE-LX SFP transceivers.
