HIGH-SPEED 2-WIRE SHORT-RANGE DSL LINE DRIVER RACK CARD
Figure 3-4. Typical Plug-and-Play application.
When the units are connected, the CP will come up with a predefined default
configuration (Receive Recovered clocking). During the handshaking process
between the units, the CO unit will set the DTE rate/line rate of the CP unit to
match its DIP-switch configuration settings. If the DTE rate for the link requires a
change, the change is needed only at the CO side of the link.
The mDSL Rack Card Plug-and-Play application will also work in the managed
system using the SNMP Management Module and mDSL Rack Cards installed in
the 2U rack system. In this application, the system administrator can configure the
entire rack through the Network Management Station (NMS) before the
standalone (CP) units are installed. For more information on the SNMP
management of your rack, please refer to the
SNMP Management Module Operations
Manual

3.3 Configuring the Rear Interface Cards
The mDSL Rack Card has five interface card options: 10BASE-T, G.703, RS-530,
V.35, and X.21. Each of these options supports one DTE interface connection and
one 2-wire line connection.
NOTE
The ME0004C rear cards are specifically designed to operate with the
ME0004C function card and must not be swapped with other function
cards.
Before installation, examine the rear card you have selected to be sure it is
properly configured for your application. Each rear card is configured by setting
straps located on the PC board. To configure the rear cards, set the configuration
straps. Figure 3-5 shows the orientation of these straps. Each strap can either be on
pegs 1 and 2 or on pegs 2 and 3.
