Installation and Operation Manual Chapter 3 Configuration

MPW-1 MP-4100 Ver. 2.0 Configuring Pseudowire Services 3-27

• Pseudowire parameters

• Attachment circuit parameters (that is, the parameters controlling the

connection of the pseudowire to the internal DS1 port)

³ To configure the pseudowire service parameters:

1. Navigate to the Configuration > Applications > Multi-Service over PSN > PW

screen of the desired pseudowire.

2. Select Service Parameters.

You will see the Service Parameters screen of the desired pseudowire.

The pseudowire index, its I/O slot, the assigned logistic name, and the

pseudowire and PSN types are automatically displayed at the top of the

screen.

3. Obtain the prescribed parameters, and then use

Table

3-10

for parameter

descriptions and configuration guidelines.

³ To configure the pseudowire service parameters:

1. After configuring the pseudowire service parameters, configure the

parameters of the attachment circuit that is served by the pseudowire, using

Table

3-11

for parameter descriptions and configuration guidelines.

Table

3-10. Pseudowire Service Parameters

Parameter Function Values

TDM Bytes in

Frame

Specifies the number of TDM payload

bytes to be inserted in each packet.

A larger value increases the

bandwidth utilization efficiency, but

also increases the connection

intrinsic latency, in particular when

the pseudowire is configured to carry

a small number of timeslots

The number is specified as a multiple of 48

bytes, for example, 1 means 48 bytes, and 30

means 1440 bytes.

The available selections for TDMoIP are 1 to 30

(48 to 1440 bytes, respectively), and the values

for CESoPSN are 4 to 360.

Default: 1

Payload Size For TDMoIP and CESoPSN

pseudowires:

Displays the resulting TDM payload

size in bytes, and considering the

selected TDM Bytes in Frame value.

For SAToPSN pseudowires:

Specifies the payload size in terms of

TDM bytes in the packet.

This parameter is not relevant for

HDLCoPSN pseudowires

The range is 4 to 1440.

For CESoPSN, the number of bytes is

determined by the Payload Size (Frames in

Packet) parameter, multiplied by the number of

timeslots assigned to the corresponding

pseudowire.
