2-WIRE IDSL LINE DRIVER RACK CARDS
E.2 Configuration
The 10BASE-T Ethernet Rear Card Module plugs into the ME0001C and ME0004C
Line Drivers to provide Ethernet LAN extension. The Ethernet Card has no
switches or jumpers and does not need to be configured. However, factors such as
the type of medium, throughput across the link, and clocking mode must be
determined by the settings of the baseband Line Drivers (ME0001C and
ME0004C).
1. Bit rate: The DTE rate setting of your base unit corresponds with the
throughput of your Ethernet Bridge Module. Use higher speeds to allow
maximum throughput to your extended LAN. Use lower speeds to limit the
access of your extended LAN.
NOTE
The Ethernet Bridge Module only supports synchronous speeds.
2. Clocking mode: Set the clocking modes on the base units so that one unit is
configured for internal clocking mode and the other unit is set for receive
recover clocking mode.
Table E-1. Base unit clock modes.

NOTE
Unit A and B are chosen arbitrarily. It does not matter which unit is A
and which is B.
3. When using the Ethernet Bridge Module, disable the Enable Loop from DTE
switch on the front function card (ME0003C or ME0004C).
4. All other base settings depend upon your application and on the application
medium (twisted-pair or coaxial cable).
