CHAPTER 4: Configuration
When the CO and CP units connect over DSL, the CP will enter a predefined
default configuration (Receive Recovered Clocking). During the negotiation
process between the units, the CO unit will configure the DTE rate/line rate on
the CP unit as defined by the settings of the CO unit. When additional bandwidth
is required, only the configuration of the CO unit should be changed. This feature
gives ISPs, LECs, and PTTs the ability to provision bandwidth on an as-needed basis
to customers.
The Plug-and-Play application will also work in an HTTP/SNMP managed system
using the Managed Micro Rack SNMP/HTTP Card (part number RM261C-SNMP)
with mDSL Rack Cards installed in a Managed Micro Rack (part number RM260).
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 HTTP/SNMP management, please refer to
the
Managed Micro Rack SNMP/HTTP Card Users’ Manual
.
4.2 Configuring the Hardware DIP Switches
The mDSL Line Driver has two sets of eight DIP switches. This section describes
switch locations and explains all settings.
The 16 external switches are grouped into two eight-switch sets, and they’re
externally accessible from the underside of the Line Driver, as shown in Figure 4-2.

showing the location of the DIP switches.
