Business need

Your customers increasingly require broadband services, but you naturally want to extend the life of deployed narrowband Digital Loop Carrier (DLC) platforms as long as possible. Wouldn't it be great to add incremental revenues and improve customer retention via the delivery of broadband services to customers served from legacy narrowband DLCs?

Challenges

Legacy narrowband DLC platforms are widely deployed and architected primarily for voice. They continue to effectively deliver narrowband services but you often need to add broadband services while avoiding the upfront costs involved with pouring new concrete and adding new outside plant equipment to create overlay networks.

Solution

It's a quick fix. Avoid the costs and delays of adding new DLCs by deploying in-cabinet upgrades to support ADSL2+ and VDSL2 services from a legacy DLC without the need for external cabinets or other expensive equipment.

Ciena's offerings

The CNX-5Plus™ Modular Broadband Loop Carrier allows you to upgrade your installed base of narrowband DLCs efficiently and deliver advanced DSL services such as IPTV. This small platform provides 96 configurable ports in a single, low-profile shelf that you can install directly inside popular narrowband DLC cabinets. This approach allows you to avoid the high upfront costs of new platforms and accelerate time-to-revenue for ADSL2+ and VDSL2 services. This solution is also deployable in adjunct DSLAM cabinets to increase DSL capacity and alleviate DSLAM exhaust. It enables a gradual evolution to advanced IP and video services, and allows you to extend the useful life of existing narrowband DLCs. Ciena also offers the CNX5™ Broadband DSL System, a simple, elegant and cost-effective solution for delivering splitterless POTS and DSL services from Lucent SLC-5 DLCs. This system enables simple, card-for-card replacements that enable DSL services over legacy SLC-5 remote terminals without compromising POTS density.
