1.1.1
Connectivity
The DLE22-MA and DLE32-MA connect to Ethernet networks or
workstations through 24 RJ45 ports on the front panel. These ports
support UTP connections up to 100 meters. The ports are IEEE 802.3
10BASE-T compliant.

The DLE23-MA and DLE33-MA connect to Ethernet networks or
workstations through two RJ21 connectors on the front panel. These
connectors support 25 pair cable at lengths up to 100 meters. The ports
are IEEE 802.3 10BASE-T compliant.

The DLE2X-MA modules have two front panel slots (ports 25 and 26) for
optional Fast Ethernet Interface Modules to support an uplink to
100 Mbps Ethernet backbones or a high speed connection to a local
server.

The DLE3X-MA modules have one front panel slot for an optional High
Speed Interface Module to provide for additional connectivity to other
high speed networking technologies such as ATM, WANs and FDDI.

Full Duplex Switched Ethernet
Each switched Ethernet port supports full wire-speed Ethernet
communications and can be configured to operate in Full Duplex
Switched Ethernet mode, which provides up to 20 Mbps of bandwidth.

SmartTrunk
The SmartTrunk feature allows the user to set a group of DLE2X-MA and
DLE3X-MA interfaces, so they can share the traffic load and effectively
increase the bandwidth between connected DLE2X-MA and
DLE3X-MAs or other devices supporting the SmartTrunk feature. For
example, Ports 25 and 26 of the DLE2X-MA could be grouped to provide
a 200-Mbps uplink.
