The Overture 45 and Overture 45+ provide the ideal solution for delivering cost-effective, managed Ethernet over DS3 applications. This ‘plug-and-play’ solution delivers carrier-class performance allowing carriers to deliver a lowcost, first-entry solution for single customer scenarios.
|'Plug-and-play' platform and design||
Compact design makes it simple to install at the customer premise, either as a wall-mounted
or rack-mounted unit
Customer traffic classification, supporting up to 10 traffic rules per port, as well as VLAN management, traffic queuing, rate limiting, policing and p-bit remarking
|In-band or out-of-band management||
Extends multiservice management visibility all the way to the remote customer edge, eliminating truck rolls—saving in OpEx costs
|Multi-level loopback testing||Provides a unique automated verification of a 10/100 link on the customer premise|
|Hands-off cable testing||Gives carriers a fast, accurate way to pinpoint cabling problems, saving time and money|
The Overture 45 and Overture 45+ can attach to an existing SONET/SDH Add Drop Multiplexer (ADM), DS3 fixed wireless link, or a leased DS3 facility. Two subscriber Ethernet ports enable prioritized traffic to be fed to the network. In a hub-and-spoke configuration, several Overture 45s can feed the Overture 6000 or other aggregation switches and can be managed in-band through the DS3 connection. The Overture 45 and Overture 45+ can also be paired back-to-back to deliver cost-effective point-to-point Ethernet and TDM interconnections.
For applications requiring Ethernet over DS3 connectivity, the Overture 45 and 45+is a simple, low cost solution.
With the Overture 45 and 45+, a service provider or network operator can enter a single customer location and capture Ethernet service revenue with a low, first-cost solution that can be deployed today and pay for itself within a few months — without having to invest in a costly build-out of the metro network. Applications include:
- Ethernet-enable an existing SONET ADM
- Back-to-back Ethernet over DS3 facilities
- High-speed Internet access
- Storage Networks
- VoIP or TDM voice interconnect
Service providers and network operators can deploy managed Ethernet services over the thousands of installed SONET/SDH add/drop multiplexers (ADMs) and rapidly extend these Ethernet services to off-net locations via leased and wireless facilities.
Deliver management and service intelligence to the remote customer edge
Using the Overture 45 and 45+ in conjunction with the Oveture 6000 or 6100 delivers the greatest value to the customer, as more intelligent services and management capabilities can be leveraged via hub-and-spoke configuration. For example, with a single Overture 6000 serving as the hub, up to 24 ISG 45/45+s can be deployed across a metropolitan area, an office park or up the risers in a multi-tenant building to deliver managed Ethernet services.
In this configuration, each Overture 45 and 45+ can be managed in-band via a management VLAN or out-of-band via Ethernet. This remote management capability allows carriers to extend IP management visibility all the way to the remote customer edge. From a single operator viewpoint, a carrier can remotely manage and provision each individual product without ever having to touch the unit itself.
The Overture 45 and 45+ units are truly designed for plug-and-play operation. Installation is simple and configurations can be performed remotely. The products also offer two hands-off cable tests — one for the DS3 uplink and one for the customer's Ethernet connection using a built-in Time Domain Reflectometer (TDR).
Flexible and Differentiated Ethernet Solutions
The Overture 45 and 45+ 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 DS3 circuits. Offering business-class Ethernet services by providing strong Class of Service (CoS) features, the Overture 45/45+ offers 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 the Overture 45 and 45+ can give Voice over IP (VoIP) traffic priority over Internet access traffic. The products 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 45 and 45+ is easy to configure, manage and monitor. Extensive performance monitoring is supported for both the DS3 and Ethernet interfaces. The Overture 45 and 45+ provides 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 45 and 45+.
The Overture 45 and 45+ complements other Overture products enabling 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.
