LoopStar® 780
Flexible Multi-service Solution for Packet-based Cell Site Backhaul
There is major shift taking place in the mobile backhaul space. Voice and data traffic are increasing
exponentially across cellular networks with a corresponding increase in the number of cell towers
and the transport networks. Providers are seeking ways to reduce network and transport costs by
supporting a strategy designed to move away from a TDM-based transport network towards a
packet network. To this end, more fiber is being pulled to cell tower locations and more Ethernet
services are being added to mobile networks. ADC’s LoopStar® 780 is ideally suited to address
the challenges of wireless carriers in this transition. Deployed at the cell tower, the cost efficient
LoopStar 780 can be used to provide standards-based circuit emulation services that allow TDM
trunks to be backhauled over an Ethernet-based network, while simultaneously supporting IP
Multimedia services to cellular users. This multi-service capability is the heart of the LoopStar 780.
The LoopStar 780 features and benefits:
• Provide cost-efficient transport of voice and data across a packet-based infrastructure
• Support legacy and next generation voice and data services
• Extend Quality of Service capabilities into the access network
• Integrate with copper, fiber, cable and radio infrastructures
• Incorporate standards-based SAToP pseudowire technology, along with full support for business-
class Ethernet services
• Low cost platform enhances the business case for cell tower installation
• Temperature hardened to adapt to a variety of environments
The LoopStar 780 offers up to eight (8) ports of Structured Agnostic Transport over Packet
Switched Networks (SAToP) for T1/E1 support. IP services are supported by four (4) subscriber-
facing 10/100 Ethernet ports and one 100FX port. The WAN interfaces are flexible, offering
both copper and fiber based backhaul solutions for 100/1000TX copper and 100FX/GigE fiber.
Additionally, the WAN interfaces offer dual uplinks for redundancy.
ADC’s LoopStar 780 was designed from the ground up as a carrier class device. It incorporates
field proven pseudowire technology, along with full support for business-class Ethernet services.
Additionally, as a temperature hardened and Telcordia NEBS Level 3 certified product, the LoopStar
780 is suitable for deployment in a wide range of environments and locations. Other carrier class
features include: redundant hot swappable power supplies, BITS timing input, alarm outputs and
EdgeAware™, a comprehensive suite of Intelligent Management and Control tools designed for
the multi-service edge.
