Introduction to ETHX-DS3-1-LT and ETHX-DS3-2-LT
Zhone's ETHX-DS3-1-LT and ETHX-DS3-2-LT are loop bonding Ethernet extenders
that provide up to 45 Mbps (ETHX-DS3-1-LT) or 90Mbps (ETHX-DS3-2-LT) of
symmetrical bandwidth using DS3 lines for transport.
The ETHX-DS3-1-LT features one DS3 port, and the ETHX-DS3-2-LT has two DS3
ports, each capable of up to 45 Mbps bandwidth. One or two ports may be used to
deliver Ethernet connections over DS3 facilities of any given length. Zhone's loop
bonded technology provides automatic load balancing and fail-over for optimum
redundancy and data throughput. In addition the ETHX-DS3-1-LT and ETHX-DS3-2-LT
support industry standard C-Bit Parity DS3 transport facilities, ensuring maximum
distance and flexibility.
The ETHX-DS3-1-LT and ETHX-DS3-2-LT can be connected in any combination so
long as every connection pairs a provider and a subscriber unit.
ETHX-DS3-x-LT units are shipped from the factory configured as provider units. This
configuration can be changed via web management. If you wish to connect a pair of
new units in a point to point network configuration, one of the units must be re-
configured to the subscriber mode. See the “Web Interface” section of this document
for the procedure to accomplish this.
