Ethernet Aggregator

RAD's ETX-550 Ethernet Aggregator combines multiple Fast Ethernet links to higher rate Gigabit Ethernet connections upstream. Up to 24 Ethernet/Fast Ethernet links can be combined into up to four Gigabit Ethernet links.

 

The ETX-550 Ethernet Aggregator is typically used in fan-out applications where the unit is deployed in the service provider’s first point of presence, delivering Fast Ethernet services to several remote Ethernet network termination units.

• Reduces the number of long-haul fiber connections

• Simple management and control of the entire system

The ETX-550 is a high performance Ethernet aggregator, which combines multiple Fast Ethernet links to higher rate Gigabit Ethernet connections upstream. It provides up to 24 Ethernet/Fast Ethernet links into up to four Gigabit Ethernet links. Typically, the ETX-550 can be used in fan-out applications, where the ETX-550 is deployed in the service providers’ first point-of-presence (POP) to deliver Fast Ethernet services over fiber to several remote Ethernet network termination units (NTUs), such as RAD’s ETX-102, located at the customer premises.

The ETX-550 operates as a Layer 2 Ethernet aggregation device and is transparent to higher protocols. It can function in VLANaware or VLAN-unaware bridging modes. Using VLAN stacking (also known as double tagging or Q-in-Q), the service provider can assign different customers to different service VLANs (S-VLANs), thereby guaranteeing separation of customer traffic within the service provider network. Customer VLANs are encapsulated by the S-VLAN and transported to allow for transparent LAN services.

Customer bandwidth can be policed to adhere to service level agreements via rate limitation per user port. Rate limitation is based on single rate bandwidth control with CIR (Committed Information Rate) and CBS (Committed Burst Size) parameters. Rate limitation can also be defined on network ports for effective management of traffic flows to the edge devices.

The ETX-550 has the following management options:

• Local (craft port)

• Out-of-band using a dedicated Ethernet port

• In-band via the Gigabit Ethernet port

 

Optionally, a dedicated VLAN can be defined for management traffic in order to separate it from user VLAN traffic. Management is SNMP based, using Telnet, Web server or RADview-HPOV.

 

Network access security is ensured through Telnet and Web applications (SSH and SSL) as well as support for secured SNMP – SNMPv3 and RADIUS.

 

The ETX-550 is a 1U-high, 19-inch wide box. It is available with one or two AC or DC power supplies.
