System Benefits

The numerous features of the DL3800E unit provide you with many benefits:

•Reliable, full performance access to E1 networks for the widest variety of DTE products

•Enterprise wide visibility via SNMP

•Local and remote access via front panel, terminal, or telnet

•Complete maintenance and diagnostic support via exhaustive alarm, statistic, and test capabilities

•Downloadable code provides for on-line upgrade to the DL3800E unit software for both major and minor feature enhancements

Application

The DL3800E unit accepts data from a high-speed bridge, router, front-end processor or other DTE device and multiplexes the bit stream onto one through eight E1 circuits for transmission at N x 1.976 Mbps. Because the inverse multiplexing process is completely transparent to the attached equipment, the combined E1 circuits appear as a single high-speed data link to the DTE. The DL3800E unit accepts up to a 31-millisecond differential delay between individual E1 circuits, ensuring reliable operation in multiple carrier networks.

A unique feature of the DL3800E unit is the automatic bandwidth response to an E1 signal loss or network errors. If an E1 link falls below acceptable performance levels, the DL3800E unit removes the link from service and reduces the DTE data rate to correspond with the remaining E1 links in service. When the alarm condition has been cleared, the DL3800E unit restores the E1 link and increases the DTE data rate to its original level.

A typical application is shown in Figure 2-2.
