Overture 500 Series


The Overture 500 series of Ethernet-over-PDH demarcation devices provides a cost-effective solution for bonding multiple T1 or E1 circuits into a single Ethernet connection, delivering over 12 Mbps of Ethernet service capacity to any business customer regardless of rate, reach, or facility availability issues.

Feature Benefit
4 or 8 E1/T1 options Flexible options optimized for the lowest cost service delivery.
CLI and web GUI A familiar CLI and Web Manager that requires no client software make this solution easy to use and scalable.
Zero Touch provisioning
Save time and money by streamlining installation and reducing the skill set required of the local field
CPE profiles
The aggregator stores different CPE profiles in order to streamline CPE configurations when multiple services are offered.
Traffic management Ensure Quality of Service with advanced traffic shaping, hierarchical queuing, and traffic policing.

The 500 operates in bookended mode, or in conjunction with Overture’s 6100 Multi-Service Access Solution, to extend Ethernet services to any customer regardless of the intermediate access network. This enables flexible low cost deployments for point to point connectivity or full scale  aggregation with the Overture 6100.

The 500 series delivers Ethernet services in a compact, economical package that easily scales in capacity and service ubiquity as part of Overture’s unique access portfolio. The 500 comes in 4-circuit and 8-circuit variants, supporting up to 16 Mbps of connectivity (in E1 mode, with 12 Mbps of connectivity in T1 mode). A robust service model including flexible VLAN manipulation, traffic shaping, traffic policing, and hierarchical traffic management allows carriers to guarantee the delivery of multiple services competing for the limited bandwidth over an access connection. The 500 also  benefits from Overture’s years of experience deploying end-to-end service OAM standards such as 802.1ag and Y. 1731, with quick and easy methods for monitoring service performance and availability across any network.

Like the 400 and 600 family of products, the 500 series is also plug-and-play with it’s Zero Touch installation capability. The central aggregator automatically creates a management channel, updates the software and pushes the configuration to any 500 series device connected. Extensive debugging and troubleshooting capabilities eliminate costly truck rolls. The product also provides a comprehensive, user-friendly command-line interface (CLI), SNMP, and an embedded Web Manager that requires no client software – all of which can be accessed over any in-band or out-of-band IP interface.

The 500 series is a temperature hardened, NEBS3 certified, full front access device, making it universally deployable in any environment - from the central office to a customer premise to a cell tower. With Overture’s 500, carriers can costeffectively deploy high-speed Ethernet-over-PDH services to business sites and cell towers that do not have access to fiber and which cannot be reached by copper.



Business Access – The Overture 500 series enables 1Mb to over 100Mb services as connections to offices typically providing Ethernet services over bonded copper and bonded T1 where there is not fiber available.  Typical business services carriers sell are metro Ethernet, dedicated Internet access, IP-VPN and VoIP.

Mobile & DSLAM Backhaul – The Overture 500 series enables 1Mb to over 100Mb services connection to cell towers, typically providing up to 100 Mbps backhaul services carrying both native Ethernet and native TDM with support for network timing synchronization. This product line is ideally suited for enabling high-speed backhaul to mobile cell towers and DSLAM sites that are capital-constrained to be served by fiber.

Multi-Tenant Campus and In-Building – The Overture 500 series enables 1Mb to over 100Mb services for campus and in-building applications. The product line enables carriers to benefit by taking advantage of the existing copper plant on campus or up the risers in buildings, realizing a huge cost savings while enabling high-speed Ethernet services.

Traffic Light/Video Surveillance – The Overture 500 series enables 1 Mb to over 100 Mb services for counties and municipalities who need to increase bandwidth to traffic lights for video surveillance applications where only existing copper plant is available.
