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.
