5.2.3 IP Receive Mode

In IP receive mode, the ASI-IP-GTW receives IP packets from the data Ethernet interface. The ASI-IP-GTW will receive streams from different sources. In the case of unicast, the ASI-IP-GTW will parse the IP stream and send the transport stream to the ASI output which is configured with the matching UDP port. In case of multicast, the ASI-IP-GTW will send a join message to join the configured multicast. When reception is disabled, the ASI-IP-GTW will send a leave message to the network.

For each transport stream, the reassembled MPEG-2 transport packets are held in a buffer. The function of this buffer is to handle re-ordering of packets, eliminate network jitter and support the adaptive rate recovery.

After clock recovery, the MPEG-2 transport stream is passed to the DVB ASI output port.

In the current version of the product, the ASI output will always output 188 byte packets. If you require 204 byte packets, please contact Network support as this is likely to be available in a future software version.

5.2.4 IP Bi-directional Mode

In IP bi-directional mode, half the ASI ports are operate as described in IP transmit mode, while the other half are operated as described in IP receive mode.

5.2.5 Management

The ASI-IP-GTW provides an Ethernet management port for configuration and control of the unit. The management port has its own IP address. This interface provides the following features:

oWEB interface for remote control

oSNMP for alarm and status monitoring (optional). o FTP for software and firmware updates

o Telnet for engineering and debug purposes

In addition, the IP address of the management port can be set though the RS232 connector.

The WEB interface is described in detail in Chapter 1. SNMP is an option to the product. The unit will send SNMP traps to report alarm conditions; in addition it is possible to read from the unit all active alarms and trap history. The MIB is available on request.

5.2.6 Alarms

The ASI-IP-GTW indicates alarm or fail status to the user in four ways:

oWEB interface

oAlarm LED on the front and on the rear

oSNMP traps to Network Management System o Alarm relay

The user can define the severity level of the different alarm events. The three levels are No alarm, Warning and Critical.
