The DS3 module allows the DNX product to connect to DS3 compatible links. The module leverages on the unique DNX architecture, occupies a single slot in the system chassis, and supports industry standard link formats.
Full support is provided for the framing overhead functions of either mode.
The DNX DS3 solution is a means of minimizing space requirements while maximizing available bandwidth, features and manageability. With tariffs for T3 circuits decreasing, this solution becomes more attractive to many network managers. The DNX can be deployed for T1 access and then, by adding the DS3 module, traffic can be groomed from existing circuits on to the T3 link. The DS3 frame is comprised of 28 T1 circuits. D4 and ESF T1 framing can be mixed in any combination for any of the 28 links.
