Connect the WAN SHDSL lines
An important feature of the EtherXtend device is the loop bonding capability
among all four SHDSL ports. However, both the provider and the subscriber
units can function with a single SHDSL connection as follows:
•
Establish a loop bonded connection on page 41
•
Connect the LAN Ethernet line on page 41
Establish a loop bonded connection
Using up to eight SHDSL lines for one network connection (loop bonding)
will net up to eight times the speed and data passing capability as a single
SHDSL connection. Multiple SHDSL lines used for one connection provide
backup for each other should one or more of the lines become disabled.
Establishing a loop bonded connection
1
Plug your SHDSL cables into the SHDSL RJ-45 ports (any combination
of SHDSL 1, 2, 3, and 4) on the rear of the device. The order of the
connection is not important.
2 Verify the connections. The SHDSL link LED for each connected port
flashes green when the connection is established and operational.
Establishing a single line connection
1 Plug your SHDSL cable into one of the four SHDSL RJ-45 ports on the
back of the device. Any of the four ports may be used.
2 Verify your connection. The SHDSL LED corresponding to the connected
port flashes green when the connection is established and operational.
Connect the LAN Ethernet line
If an SHDSL connection has not yet been made, the Ethernet link remains
disabled as indicated by no illumination of the LEDs until at least one of the
four SHDSL lines are established.
The 10/100 Ethernet port auto-negotiates speed and duplex mode in
accordance with the remote equipment to which it is connected.
•
Half Duplex - Receive and transmit functions are mutually exclusive; data
transmission occurs in only one direction at a time. Packet collisions are
unusual.
•
Full Duplex - Receive and transmit functions occur simultaneously,
effectively doubling aggregate bandwidth and preventing packet
collisions.
