The one- and two-port E3 port adapters provide direct connectivity to E3 lines for full duplex communications at the E3 rate of 34.368 MHz. With integrated line interface units (DSUs) that allow E3 lines to be directly terminated on a Cisco router, these interfaces provide a more cost effective solution than a combined HSSI interface plus external DSU solution.
These products feature interoperability with E3 DSUs from major vendors including Digital Link and Kentrox.
Key Features:
E3 connectivity with no external DSU required
Subrate E3 support
Scrambling support
High density: Up to 4 E3 ports per 7500 slot
Unframed or G.751 (software selectable-G.751 default)
Software settable E3 national service bits
