Subscriber Unit - Zhone ETHX-2214-DS3 Installation Instructions Manual

Provider vs Subscriber Units
The EtherXtend 2200 DS3 units can be operated in either a Provider or Subscriber
mode. A Subscriber unit is always considered as a 'slave' to the Provider unit, which
acts as a 'master' when enabling the DS3 ports and loop bonding configurations.
Therefore when using the ETHX-22x4-DS3 devices in a network, one Provider and one
Subscriber unit are required on the unframed DS3.
Typical applications of EtherXtend 2200 DS3 EADs are shown in the figure below. Note
that devices can be connected together, in a point-to-point (or book-ended)
configuration, using either a single 45 Mbps unframed DS3 facility or two unframed
DS3s (for a total bonded capacity of 90 Mbps). Alternatively, a star configuration is
supported wherein a single ETHX-2224 can be connected to two separate ETHX-2214
units, each connected via a single unframed DS3 facility. The only constraint is that
each connection pairs a unit operating as a Provider Unit with a unit operating as a

Subscriber unit.

All EtherXtend 2200 DS3 units are shipped from the factory preconfigured to operate in
the Provider mode. The operating mode of a unit can be changed via web
management. See the "Web Interface" section of this document for the procedure to
accomplish this.
NOTE: ETHX-22x4-DS3 units are not compatible with DNE4500 devices
ETHX-22x4-DS3 devices must be connected in one of the configurations
depicted above. These units are not compatible with the former Net-to-Net /
Paradyne DNE4500 DS3 network extenders.
