The DL3800E unit features an automatic rate fallback in the event of a failing E1 circuit. If the performance of an E1 circuit is detected to be falling below accepted levels, the DL3800E unit automatically removes the E1 from service, and throttles back the DTE to a data rate corresponding to the remaining E1s. When the alarm condition on the affected E1 has been cleared, the DL3800E unit can automatically restore the E1 and data rate.

You can configure, control, and monitor the DL3800E unit through the front panel, an ASCII terminal (locally or remotely via a modem or remotely in-band) or a Simple Network Management Protocol (SNMP) management station. The remote DL3800E unit can be managed in-band using overhead in all active connections as the communications path. The DL3800E unit features an integrated SNMP agent which supports the E1 Management Information Base (MIB) in addition to a unit specific enterprise MIB.

A downloadable software feature of the DL3800E unit allows new features and functionality to be added to the unit on line (without interrupting the data) via the unit's built-in communications port, or via a selected E1 connection.
