port, but the parameters are actually changed only when the database is
updated.
To avoid redundancy configuration errors, use the following procedure:
1. Before starting the configuration of the redundancy parameters, decide
which port of the planned redundancy pair is to serve as the primary port,
and make sure that the other port does not carry traffic.
You must always start configuring the primary port, and only after this port is
fully configured, continue to the redundancy partner of the primary port.
2. Fully configure the port that is to serve as the primary port. After parameters
are configured, the redundancy slot, channel (port) and primary status
indicator become read-only fields.
In parallel, the parameters of the alternative port are also configured to
compatible values.
3. After ending the configuration of the primary port, configure the alternative
port. When you open the alternative port configuration screen, you will see
read-only fields which display all the preconfigured parameters, and then the
list of parameters that can be configured.
4. To change the redundancy assignments, first select None for the Redundancy
parameter. This will enable you to reconfigure the system as required.
Configuring Internal DS1 Port Timeslot Utilization
The internal DS1 port provides a connection point between TDM traffic arriving
from other modules and the pseudowires supported by MPW-1. Each pseudowire
can be connected to only one internal DS1 port.
When an MPW-1 internal DS1 port uses the DS0 cross-connect mode (available
when the port uses the Framed mode), it is necessary to connect individual
timeslots to the prescribed ports on the other I/O and CL modules, in accordance
with the application requirements (this action is referred to as
timeslot
assignment
). To continue the connection over the pseudowire, when you
configure the pseudowire you also specify the internal DS1 port timeslots to be
collected and processed by it. You can assign timeslots only to internal DS1 ports
that have been already configured, and that have their Administrative Status set
to Up.
For the supervision terminal, use the last item, Time Slot Assignment, on the
Configuration > Physical Layer > I/O screen of the desired MPW-1 internal DS1
port, or use the Configuration > System > TS Assignment screen in accordance
with the
Megaplex-4100 Installation and Operation Manual .
The connection of timeslots from the internal DS1 port to each local pseudowire
is made using the Time Slots item on the Configuration > Applications > Multi-
Service over PSN > PW > Service Parameters > Attachment Circuit screen.
Timeslots can be assigned for the following purposes:
• For connection to any other port of an I/O or CL module that uses the DS0
cross-connect mode (for example, framed E1 or T1 ports), or an I/O channel
