Ericsson Marconi OS860¶
Modular STM-1/4 ADM-Multiplexer with E1, E3 and STM-1 interfaces. We have two of them by now.
Add/Drop multiplexers could be used to transport a variety of E1 lines over longer distance via fiber optic transceivers. Assuming a future CCC event at a large venue, one could connect multiple "points of presence" with a STM-1 backbone.
