The TC3844-3 Ethernet-over-T3/E3 Gateway
allows the user to connect a JumboSwitch network over
existing T3/E3 circuits. With the large installed base of
T3/E3 infrastructure, remote locations that are not within
reach of optical fiber can now be supported with all of the
multi-service capabilities of the JumboSwitch. These
locations can be connected via microwave radios, through a
service provider’s network, or a private SONET/SDH network.
Although the TC3844-3 is designed to offer
flexible alternative connectivity between JumboSwitch nodes,
it can also be deployed as a stand-alone item to connect any
third party Ethernet networks over T3/E3 circuits. Used in
pairs, the modules convert the Ethernet data into framed or
unframed T3/E3 format for transmission over T3/E3 links.
The TC3844-3 performs store-and-forward of
frames with Ethernet traffic conditioning and bridging
functions at wire speed, fully utilizing the TDM circuit.
The internal bridge supports VLAN tagging and priority
labeling which enables the user to define different QoS
levels according to the application requirements.
A variety of important features are included
such as fault management, auto-negotiation with flow
control, Statistics Monitoring, Network Time Protocol,
Remote Firmware Upgrade and Temperature and Power
In-band and out-of-band management are
accessed via Web, SNMP, Console and Telnet. Diagnostic tools
include LEDs, dry contact alarms and local and remote
loop-back. The TC3844-3 interface card can fit into any
available JumboSwitch housing option including 2S Standalone
chassis and 1U/2U/4U card cages. Power Redundancy is
standard and power supply options available for standalone
version are 90-260VAC, 12VDC, 24VDC and -48VDC. Standard
operating temperature is -20°C to +70°C and the extreme
temperature version is -40°C to +80°C.
