The DM820 is a new generation compact SDH fibre optic multiplexer with 2Mbit/s E1, 34/45Mbit/s E3, Ethernet/Gigabit Ethernet and SDH STM 1, STM 4, STM 16 support. With a fully modular platform, DS0 cross-connect, MPU redundancy, multiservice functionalities and operates with multiple rings and point-to-point links.
DM830 is a compact new generation SDH fibre optic multiplexer. Supports 2Mbit/s E1, 34/45Mbit/s E3, Ethernet/Gigabit Ethernet and up to SDH STM-16 interface modules. Modular platform. DS0 cross connection from 384 E1s to 1008 E1s. Multiservice functionalities. Can operate in multiple rings and point to point applications.
The DM881 is a SDH fibre optic multiplexer and multiservice concentrator. It supports a switching matrix with a SDH capacity between 7.4G and 40G, and also includes a DSO cross-connect between 384 E1s and 1002 E1s. It operates with the following interfaces: E1, E3/T3, STM 1, STM 4, STM 16, Fast Ethernet and Gigabit Ethernet. It offers SDH-NG functionality and can concentrate up to 384 E1 ports per chassis.
The HX9416R is the largest configuration of HX9400R series of the ADM/TM SDH fibre optic multiplexers. This configuration with two CC16 CPU and aggregate provide a traffic’s concentration over the two 2 STM16 (2,488 Gbps) SNCP rings up to 8 STM1 or 2 STM4 sub-rings in a single node and the full cross-connect of all VC12, VC3 and VC4.
