Single DS3 Connection
A single line connection can be established between a single port Subscriber unit and
either a single port or dual port ETHX-2224-DS3 Provider unit. Likewise, a single line
connection can be established between a single port Provider unit and either a single
port or dual port ETHX-2214-DS3 Subscriber unit.
Procedure
1. Plug two coax cables, one for transmit (Tx) and one for receive (Rx), into the DS3
BNC 75 ohm port on the back of the network extender.
2. After connecting the other ends of the DS3 cables to suitable transport or
multiplexing equipment, verify that there is a DS3 connection to the ETHX-22x4
unit by confirming that the DS3 LINK/ALARM LED on the front of the network
extender flashes green to indicate the connection is established and operational.
Refer to Table 2 on page 12 for a description of the DS3 LED indicators
Dual DS3 Loop Bonded Connections
Using two DS3 lines for one network connection (loop bonding) effectively doubles the
speed and data throughput capability of the network extender. Two DS3 lines also act
as a backup should one of the lines become disabled.
Procedure
1. Plug the DS3 cables into the DS3 BNC 75 ohm connectors on the back of the
network extender. Each DS3 connection requires two coax cables; one for
transmit (Tx) and one for receive (Rx). Either port can be connected first.
2. After connecting the other ends of the DS3 cables to suitable transport or
multiplexing equipment, verify that there are DS3 connections to the ETHX-22x4
unit by confirming that the DS3 LINK/ALARM LEDs on the front of the network
extender flashes green to indicate that the connections are established and
operational. Refer to Table 2 on page 12 for a description of the DS3 LED
indicators
