Ethernet Aggregator and Optical Transceiver
with On-Board Chassis Management [DLM205]
DigiLink Video Transport System
The DLM205 combines a 9 port non-blocking Ethernet switch and
aggregator with DL4000 chassis management capabilities.
The innovative design of the DLM205 enables users to manage and monitor DL4000
chassis as well as aggregate 9 channels, 5 external and 4 internal, of 10/100/1000 Ethernet
traffic for transport across electrical or optical networks, all in a low cost, single slot
DigiLink module. The module is fully non-blocking with a total capacity of 18 Gigabits
of traffic plus chassis management and each port independently supports 10/100/1000
Ethernet. The four internal ports can be linked to other modules in a DigiLink chassis to
provide internal Ethernet connectivity eliminating the need of external cabling.
Unlike more complicated designs that require dedicated trunking modules and switching
matrixes, the DLM205 is a simple Ethernet aggregator compatible with all DigiLink chassis.
When used in a DL4000 chassis an additional channel is enabled that includes capabilities
to manage, monitor, configure a chassis via DigiLink Manager HTTP browser based EMS
or SNMP. The DLM205 provides a simple, reliable, and low cost solution for transporting
video centric traffic and chassis management across Ethernet networks.
