Type MEM-4552 Gigabit Ethernet to ASI Network Interface Adapters from IRT Electronics

Supplier News

The MEM-4552 Ethernet to ASI Network Interface Adapters from IRT Electronics  act as a gateway between an Ethernet network and an ASI environment.

The MEM-4552 Gigabit Ethernet to ASI Network Interface Adapters generate a compliant DVB ASI transport stream, with a settable Program Number identifier, at a fixed settable data rate. When Ethernet data is available to send it is encapsulated into ASI packets. When there is no Ethernet data available, NULL packets are used to stuff the ASI stream to the selected rate.

On the receive side packets containing Ethernet data are extracted from the ASI stream by reference to the assigned Program Number.

The Ethernet port is set up automatically to accommodate most network environments. The ASI output rate is SNMP selectable to operate at a payload data rate of between 1 Mb/s and 213 Mb/s.

The Ethernet port has automatic MDI/MDI-X detection. This detects whether the Ethernet interconnect cable is a straight through or cross over type and automatically switches itself to accommodate.

The output ASI stream is suitable for transfer by any ASI type of signal path, such as IRT’s ASI single and MUX fibre link cards. G.703 rates can be set on the output to cooperate with ASI-G.703 products. For full duplex action a return link is required. Note that the return ASI rate is independent of the outgoing ASI rate.

SNMP (Simple Network Management Protocol) is included for remote monitoring and control when used in conjunction with IRT’s 4000 series frame fitted with SNMP capability.

The MEM-4552 Gigabit Ethernet to ASI Network Interface Adapters are designed to fit IRT’s standard 1RU and 4000 series 3RU Eurocard frames fitted with IRT’s SNMP system.
