Chapter 3 Configuration Installation and Operation Manual
3-12 Putting a New MPW-1 Module in Service MPW-1 MP-4100 Ver. 2.0
that supports connection of individual timeslots (for example, a high-speed
data module).
For PDH ports, make sure to map the PDH port to the prescribed TU of the CL
STM-1 or OC-3 port (for the supervision terminal, use Configuration >
System > Mapping, using the instructions appearing in the
Megaplex-4100
Installation and Operation Manual
).
• For transferring inband management (relevant only for connections to other
E1 or T1 ports). Only one management timeslot can be assigned per port
The available timeslot types are the same timeslots described for the
Configuration > System > TS Assignment screen in the
Megaplex-4100 Installation
and Operation Manual
.
Note that a timeslot assignment for a connection between two ports is accepted
as valid only when it is symmetrical, that is, a suitable timeslot of the destination
is also connected to the source port timeslot.
When using redundancy, timeslot assignment can be performed on either the
primary or the secondary port, and the timeslot assignment is automatically
copied to the redundancy partner of the primary port.
Configuring Internal DS1 Port Connections
An MPW-1 port using the DS1 cross-connect mode can only be connected to
another port that uses the DS1 cross-connect mode and the same framing mode
(Framed or Unframed).
Note that for ports using the DS1 cross-connect mode, the internal DS1 port
bandwidth cannot be split among multiple pseudowires, and therefore the whole
port bandwidth must be assigned to only one pseudowire. Although the internal
DS1 port bandwidth is equivalent to 32 timeslots, the pseudowire bandwidth
depends on the number of timeslots available at the other port:
• For E1 ports: 32 timeslots when using the Unframed mode, or 31 timeslots
when using a Framed mode
• For T1 ports: 24 timeslots (possible only in the Framed mode)
The other port is specified as part of the port physical layer parameters. The
following selections are supported:
• An external or internal port of another I/O module using the same framing
mode
• A PDH port on a CL.1/155 or CL.1/155GbE module (relevant only for the
Framed mode). The corresponding PDH must then be mapped to the
prescribed TU of an STM-1 or OC-3 port. For the supervision terminal, use
Configuration > Logical Ports > CL, and Configuration > System > Mapping,
respectively (for instructions, refer to the
Megaplex-4100 Installation and
Operation Manual
).
Configuring Physical Layer Parameters of Ethernet Ports
³ To configure the physical layer parameters for the MPW-1 Ethernet ports:
1. Navigate to the Configuration > Physical Layer > I/O screen, and then select
the I/O slot of the desired MPW-1.
