2-WIRE SHORT-RANGE DSL LINE DRIVER (MDSL)
4. Configuration
There are two modes of operation for the Line Driver: Plug-and-Play and self-
configuration. Both are described in this chapter.
4.1 Plug-and-Play
The Plug-and-Play feature allows ISPs, carriers, and PTTs to quickly upgrade the
link speed to configure the Customer Premise (CP) Line Driver. This feature also
allows service providers to set up all of the configurations at the Central Office (on
the rack cards) before installing the standalone units, saving time spent
configuring or re-configuring DIP switches.
The Plug-and-Play feature allows you to configure the DTE rate (bandwidth
allocation, see Switches S3-1 through S3-6) of the CP unit from the rack card at the
Central Office (CO). The standalone unit at the Customer Premise (CP) site will
automatically configure itself to the DTE rate (bandwidth allocation) of the rack
card. Other configuration parameters remain in the default setting.
Follow the instructions below to activate Plug-and-Play between CO (mDSL Rack
Card, ME0004C) and CP (mDSL Line Driver, ME0005A-10BT) units:
1. Set the mDSL Rack Card (CO) to either Internal or External clocking mode
as defined by the application.
2. Set the mDSL Line Driver (CP) to “Plug-and-Play CP” by setting all S2 and S3
DIP switches in the OFF position as described in Figure 4-1.
