MPW-1 MP-4100 Ver. 2.0 Normal Indications 3-1
Chapter 3
Configuration
This Chapter provides specific configuration information for MPW-1 modules.
The configuration activities are performed by means of the management system
used to control the Megaplex-4100 unit.
For general instructions, additional configuration procedures, and background
information, refer to the
Megaplex-4100 Installation and Operation Manual .
• MPW-1 modules provide pseudowire services to the other modules installed in
the Megaplex-4100. Therefore, before configuring MPW-1 modules it is
recommended to configure the other Megaplex-4100 modules and services. In
particular, make sure to configure Ethernet services.
• Make sure to plan ahead the configuration sequence, because Megaplex-4100
databases can be updated only after correctly completing the configuration
activities: any sanity error will prevent saving the changes to the database
being modified. For example, a common cause of sanity errors that may
prevent updating the database is that timeslots have to be assigned to ports
of other modules that will be served by the MPW-1 ports.
MPW-1 configuration includes the following types of tasks:
• Tasks needed to configure an MPW-1 module and put it into service. These
tasks include enabling the desired module physical ports, configuring their
parameters, and configuring the utilization of the module TDM (internal DS1)
ports.
• Tasks related to the provisioning of pseudowire services.
• When necessary, modify the system timing reference to use selected
pseudowire connections for the Megaplex-4100.
The recommended configuration sequence for each type of task is described
below, together with references to the supervision terminal screens used to
perform each task.
³ To configure an MPW-1 module and put it into service (see
Section 3.3 ):
1. If necessary, program (add) an MPW-1 module not yet installed in the
Megaplex-4100 chassis to the database.
For the supervision terminal, use Configuration > System > Card Type.
2. Configure the physical layer parameters for the active internal DS1 and
Ethernet ports of the MPW-1 module.
For the supervision terminal, use Configuration > Physical Layer > I/O.
3. Configure the utilization of the module TDM ports:
