Connecting the DS3 Lines
The primary feature of the network extender is loop bonding capability, although both
the provider and subscriber units are able to function with a single DS3 connection.
Loop Bonded Connection
Using two DS3 lines for one network connection (loop bonding) multiplies the speed
and data passing capability of the network extender. Two DS3 lines also act as a
backup should one of the lines become disabled.
A network extender can only establish loop bonded connections with other Zhone
equipment with the loop bonding feature.
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.
