TRANSPAC
PDN subscription service.
Use Bitmap
Displays the Bitmap (hex) field and allows you to construct a 32-bit status word for
specifying certain low-level attributes of the interface between the router and the
X.25 service provider. Table 13-1 (page 13-13), “X.25 PDN Parameter Bitmap
Argument Values”, shows you how to construct the status word. Enter the status
word in eight-digit hexadecimal format.
Pkt Size
Determines the maximum number of bytes in the information field of an X.25 level-3
packet.
Default: 128
Range: 1 to 2048
Note: Current buffer size limitations prevent upper level redirecting protocols from
presenting packets larger than 1600 bytes to X.25. Consequently, the actual maximum
size of the information field that will actually be transmitted by X.25 (even if Pkt Size
is set to 2048) is 1600 bytes.
Pkt Window
Determines the maximum number of outstanding (unacknowledged) packets.
Default: 2
Range: 1 to 127
Precedence
Enables or disables a request for “Level 0" precedence.
Default: Deflt
Deflt
Disables precedence requests.
Negot
Enables a request for “Level 0" precedence in all outgoing calls.
PVC
Enables or disables permanent virtual circuits (PVCs).
Default: No
No
Disables permanent virtual circuits.
Yes
Enables permanent virtual circuits. When PVC is enabled, the Low PVC LCN and High
PVC LCN parameters take effect.
Quality of Service
Determines the quality of service. You must set this parameter to X.25 for LAPB
circuits.
Remote DTE Address
Specifies the network-supplied decimal number (X.121 address) identifying the
interface between the remote peer and the X.25 network.
