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.
