Juniper Monday introduced a system for scaling mobile backhaul networks.

Juniper's Mobile Backhaul Solution includes a new cell site gateway, circuit emulation aggregation modules for the company's M-series routers, and enhancements to its JUNOScope network management system.

The Mobile Backhaul Solution is designed to upgrade legacy TDM and ATM backhaul networks for high-bandwidth data services. Mobile operators are increasingly investing in packet backhaul to reduce the cost per bit, as well as scaling the backhaul to support the rapid uptake of the mobile data services, Juniper says, citing data for Infonetics.

Operators and mobile backhaul transport providers invested $4.5 billion in backhaul equipment in 2007, according to Infonetics, which projects the market to grow to $8.2 billion in 2010, with IP/MPLS/Ethernet packet equipment growing fastest.

Juniper's addressing that opportunity with the BX 7000 Multi-Access Gateway. The BX 7000 transports a range of backhaul service types -- TDM, ATM and Ethernet -- over an IP/MPLS connection using MPLS pseudowires.

The BX 7000 is designed to allow mobile operators to retain their existing investments in 2G and 3G cell sites, while migrating to an IP/MPLS-based transport. Services can be migrated gradually, for example, by offloading data transport as a first step, Juniper says.

The BX 7000 also includes a timing expansion module that allows customers to replace clocking and synchronization systems as they change technologies. The BX 7000 also provides an expansion slot for a variety of backhaul network uplinks.

The circuit emulation interface cards for the M-series routers allows operators to deploy them as aggregation site gateways. They include a 12-port T-1/E-1 card and a four-port OC-3/STM-1 module.

The software enhancements to the JUNOScope management system are designed to simplify the deployment, provisioning and management of mobile backhaul networks.

The software automatically configures the BX 7000 upon installation, Juniper says. JUNOScope enhancements also perform monitoring and diagnostics; remote software upgrades; configuration management; and inventory management across all of Juniper's mobile backhaul products, the company says.

The BX 7000 and M-series circuit emulation cards are expected to be available in the fourth quarter. Pricing was not disclosed.
