The CNX-5 Broadband DSL System is a simple, elegant, cost- effective solution that DSL-enables Lucent SLC® Series 5 (SLC-5) Digital Loop Carriers (DLC). This unique approach to DSL deployment enables service providers to deliver both POTS and DSL services on any copper pair without compromising POTS density. The CNX-5 leverages service providers’ investments in installed DLC equipment, providing the most cost-effective solution for delivering DSL services from the DLC. Inexpensive to purchase and install, the CNX-5 expands in two-channel increments and provides T1, Inverse Multiplexing over ATM (IMA) and DS3 network interface options to utilize existing backhaul facilities.

The Challenge

The exploding demand for broadband service, and rapidly expanding competition from cable providers, has created an urgent need for service providers to deliver DSL to customers serviced by DLCs. However, current solutions for delivering DSL from remote terminals ranging from remote DSLAMs to bolt-on Mini-RAM systems are bulky, cumbersome, and cost-prohibitive. These offerings require additional space in a remote terminal cabinet, or worse, an incremental investment in concrete pads and cabinets. To really compete, service providers require a fast, simple, and reliable upgrade to their installed base of SLC-5 systems, one that is cost-effective and provides considerable capacity for growth.

The CNX-5 Solution

The CNX-5 Broadband DSL System fulfills this need. It allows service providers to introduce DSL service easily while fully leveraging their investments in SLC-5 DLC installations. The CNX-5 is available in T1 IMA and DS3 configurations to accommodate different network architectures.

CNX-5 Benefits

Simple: The CNX-5 allows a SLC-5 to be DSL-enabled with simple card-for-card replacements, with no reduction in POTS capacity.

Elegant: The CNX-5 requires no backplane cabling, “pizza boxes”, POTS splitters, or additional pads and cabinets— just a simple card-for-card upgrade.

Cost-effective: Lower start-up, expansion, and inventory costs make the CNX-5 much less expensive than Mini-RAMs and remote DSLAMs. Scalable: The CNX-5 provides cost-effective DSL growth in two line increments without reducing POTS capacity, and the CatenaView™ EMS is expandable to hundreds of thousands of lines in many different configurations.

CNX-5 in the Network

Standards-based and interoperable with all major Customer Premises Equipment (CPE), the CNX-5 provides the data transmission and voice interface between end users and the Central Office (CO). Ciena cards operate together to provide the capabilities of a DSLAM, while preserving the functionality of POTS and legacy services on the SLC-5. CNX-5 dual channel banks can be networked into multiple configurations depending on density requirements and backhaul options, so service providers can deploy the simplest and most cost-effective DSL system to suit their unique requirements.
