Chapter 3 Configuration Installation and Operation Manual
3-10 Putting a New MPW-1 Module in Service MPW-1 MP-4100 Ver. 2.0
Parameter Function Values
Framing Selects the handling of the payload
flowing through the selected internal
DS1 port
FRAMED – Enables separate handling of each
individual timeslot. In this mode, it is also possible to
connect to either E1 ports or T1 ports (for T1 ports,
the maximum is 24 timeslots).
UNFRAMEDThe port is considered as a whole (all
its timeslots are handled as a single group).
Default: FRAMED
Signaling
Specifies whether the selected internal
DS1 port carries signaling information
(for example, channel-associated
signaling).
This parameter is displayed only when
using the FRAMED mode
YES Port carries signaling information. Use this
selection when port timeslots will be defined as
VOICE timeslots.
NO No signaling information.
Default: NO
TS Assignment
Displays the timeslot assignment
submenu for this port

Redundancy Configuration Guidelines
The MPW-1 modules support redundancy for protecting the traffic flowing
through each of its internal DS1 ports. The redundancy mode is always revertive,
that is, the traffic is automatically switched back to the primary port as soon as it
returns to normal operation (except for a delay selected by means of Wait to
Restore).
The redundancy partner ports can be located either on the same module, or on
another module, in which case it is also possible to use internal (logical) ports of
other I/O or CL modules.
When using the redundancy feature, it is necessary to select the same values for
the following parameters of the two ports configured as a redundancy pair:
Framing
Signaling
Voice OOS
Data OOS
Restoration Time
Cross-Connect
However, you can select different Wait to Restore times, because the times
selected at the two ends should be different.
To save duplication of configuration parameters, all the parameters listed above
are selectable only for the primary port. The parameters of the other (alternative)
port are automatically copied from the primary port after the configuration of the
primary port has been completed and the database has been updated.
The same is true with respect to timeslot assignment: only one port (either the
primary or the secondary) must be configured, and the timeslot assignment is
automatically copied to the other port.
Note that you can see the automatically changed parameters of the other port as
soon as a redundancy partner is specified during the configuration of the primary
