CNX-5
Broadband DSL System

Benefits of the CNX-5 system

Network Interface Flexibility
The CNX-5 system provides T1, IMA and DS3 network interface options to utilize existing backhaul facilities. The T1 interface can be connected to a fiber mux or directly interface to copper backhaul facilities. IMA allows the ATM data stream to be split across T1 circuits, thereby combining the bandwidth of multiple T1 links into a single logical interface. DS3 enables service providers to provide premium service levels and serve greater numbers of subscribers to meet growing DSL demand.

Cost-effective and Scalable
The CNX-5 provides an attractive price curve when compared with alternative solutions—from initial start-up through deployment and maintenance. It is inexpensive to install, expands in two-line increments and scales to high DSL densities.

Aggregation Capability
The DS3 configuration uses a fiber ring to aggregate ATM traffic from multiple CNX-5s onto a single DS3 network interface. For smaller deployments, the T1 IMA configuration supports T1 subtending of additional CNX-5s. These aggregation options allow service providers to optimize utilization of limited backhaul bandwidth.

Minimal Retraining of Personnel
The ECU installs and operates the same way as legacy SLC-5 channel units, and ADSL is provisioned the same way as typical DSL services from a DSLAM. As a result, minimal retraining of technical personnel is required for installation of CNX-5 cards.
