Overture 140 and 180

Extending Ethernet services to all customers over readily available T1/E1 facilities

It is estimated that only 15% of all US businesses today are reachable via fiber, while the remaining 85% are reachable only by copper (T1 or E1 connections). That why we built the Overture 140 and Overture 180 to specifically reach off-net customer locations easily and economically using existing T1/E1 lines. The Overture 140 offers highly manageable 10/100 customer access and up to four T1/E1s (eight T1/E1s for the Overture 180) for the network connection. These T1/E1s are bonded using either Multilink Point-to-Point Protocol (MLPPP) or PDH VCAT, offering up to 12 Mb/s (T1) or 16 Mb/s (E1) of service.

Flexible and Differentiated Ethernet Solutions

The Overture 140 and 180 provide economical point-to-point or, when paired with an Overture 6000 or other standards-based switches, hub-and-spoke Ethernet services to customer locations that can only be reached through T1 and E1 circuits. Offering business-class Ethernet services by providing strong Class of Service (CoS) features, the Overture 140 and 180 offer much more than raw Ethernet transport and can be used for:

• Full range of 4,095 Virtual LANs
• Layer 2 Virtual Private Networks (VPNs)
• Traffic prioritization and classification – Eight User Data Queues

For example, the advanced traffic classification features of either the Overture 140 or 180 can give Voice over IP (VoIP) traffic priority over Internet access traffic. Thy support up to ten rule-based classifications based on any of the following inputs: VLAN ID, VLAN P-bits, ToS bits and DiffServ Code Points. In addition to this classification scheme, rate limiting, policing and shaping are also provided to round out a full suite of tools for customer provisioning and service.

Easy Fit into Existing OAM&P Infrastructure

• With an in-band management VLAN channel, robust GUI and full SNMP connectivity, the Overture 140 and 180 are easy to configure, manage and monitor.  Performance monitoring is supported for both the T1/E1 and Ethernet interfaces. The Overture 140/180 provide a comprehensive fault management through the use of equipment and facility alarms available over both the in-band management channel and through the local management console port.  SLAs can be monitored through the use of the Service OAM feature set (802.1ag and Y.1731) integrated into the Overture 140 and 180.
• The Overture 140 and 180, combined with other Overture products, create a solution that enables service providers and carriers to create new business revenues by delivering high-margin Ethernet services to all of their customers, no matter where they are located on the network.
