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

acombination 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.

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.
