4.2.2 Configuration DIP Switch Set “S3”
Use the DIP Switches in Switch S3 to set the DTE Rate (for LAN
Bandwidth Allocation), the transmit data sampling point and to reset
the unit to its software default settings. The following table summa-
rizes default positions of DIP Switch S3. Detailed descriptions of each
switch follow the table.

switch follow the table.
Switch S3-1 through S3-6: DTE Rate
Use Switch S3-1 through S3-6 to provision bandwidth to the LAN
in 64kbps increments up to 2.304Mbps. Peak bandwidth utilization on
the local domain on an Ethernet LAN runs typically between 15% to
20% (1.5Mbps to 2Mbps) of the maximum bit rate of 10Mbps. Traffic
between LANs typically runs even lower -- between 2% to 7%
(200kbps to 700kbps) of the maximum bit rate depending upon appli-
cation and environmental conditions. This is the amount of traffic that
will run across the DSL span.

Set Switches 3-1 through S3-6 to allocate bandwidth based upon
expected LAN to LAN traffic rates. As an example, set applications
which low LAN to LAN bandwidth content between 64kbps and
576kbps. Applications with high bandwidth LAN to LAN content should
be set between 576kbps and 2.304Mbps as required.

Switch S3-8: Reserved
Switch S3-8 is reserved for factory use and must remain in the On
position.
NOTE:
The Model 1088 will automatically select the optimum
line rate for the required distance based on the DTE rate set by
Switches S3-1 through S3-6. This selection is based on the low-
est line rate that will support the DTE rate.
