EDA 1200 Nodes
The 288-line IP DSLAM EDN288x is ordered, delivered, installed, and
commissioned as one pre-assembled, pre-cabled, and tested unit. EDN288x
consists of 24 x 12-line IP DSLAMs (EDN312x), one Ethernet Controller Node
(ECN330), 24 numbered Ethernet cables, and a power cable, all assembled in
an 11 HU chassis. The EDN288x chassis can be plugged directly into existing
19” or ETSI racks and connected to upstream Ethernet over copper or fiber.
EDN288x is power fed from a standard telecom graded –48 V DC power
supply. Traffic from the EDN288x is delivered on one or two Gigabit Ethernet
fiber interfaces.

ECN330, Ethernet cables, and mounting brackets.
