PAD and X.25 Connection Setup Commands

This chapter describes the function and displays the syntax for the commands used for configuring an internal packet assembler/disassembler (PAD) application to make connections with remote devices using the X.25 protocol. For more information about defaults and usage guidelines, see the corresponding chapter of the Dial Solutions Command Reference.

pad

To log on to a PAD, use the pad user EXEC command.

pad {x121-address | hostname} [/cud text] [/debug] [/profile name] [/reverse] [/use-map]

x121-address	Specifies the X.121 address of the X.25 host.
hostname	Specifies the X.25 host name if the host-to-address mapping has been set with the X.25 host command.
/cud text	(Optional) Includes the specified text in the Call User Data field of the outgoing Call Request Packet.
/debug	(Optional) Displays the informational level of logging messages whenever the remote host changes an X.3 parameter setting or sends any other X.29 control packet.
/profile name	(Optional) Sets X.3 PAD parameters for the name script. This is the same as issuing the x29 profile global configuration command when translating X.25.
/reverse	(Optional) Causes reverse-charge calls to be accepted on a per-call (rather than a per-interface) basis.
/use-map	(Optional) Applies x25 map pad command entry options (such as CUD and idle) and facilities (such as packet in, packet out, win in, and win out) to the outgoing PAD call. This function occurs only if a matching X.121 destination address exists in a x25 map pad command entry.

resume (setting X.3 PAD parameters)

To set X.3 parameters, use the resume EXEC command as follows:

resume [connection] [/set parameter:value]

connection	(Optional) The name or number of the connection; the default is the most recent connection.
/set parameter:value	(Optional) Sets the X.3 connection options and PAD parameters for the Cisco IOS software.

service pad

To enable all packet assembler/disassembler (PAD) commands and connections between PAD devices and access servers, use the service pad global configuration command. Use the no form of this command to not accept incoming and outgoing PAD connections.

service pad [cmns] [from-xot | to-xot]
no service pad [cmns] [from-xot | to-xot]

cmns	(Optional) Specifies sending and receiving PAD calls over CMNS.
from-xot	(Optional) Accept XOT to PAD connections.
to-xot	(Optional) Allow outgoing PAD calls over XOT.

show x25 pad

To display information about current open connections, including packet transmissions, X.3 parameter settings, and the current status of virtual circuits, use the show x25 pad user EXEC command.

show x25 pad

where

To list the open sessions, use the where EXEC command.

where

x3

To set X.3 PAD parameters, use the x3 EXEC command.

x3 parameter:value

parameter:value

Sets the PAD parameters.

x25 subaddress

To append either a physical port number or a value specified for a line as a subaddress to the X.121 calling address, use the x25 subaddress line configuration command. Use the no form of this command to disable subaddressing.

x25 subaddress {line | number}
no x25 subaddress {line | number}

line	The physical port number for the indicated line will be appended to the X.121 address as the subaddress.
number	Numeric variable assigned to a specific line.

x28

To enter X.28 mode and access an X.25 network or set X.3 PAD parameters, use the x28 EXEC command.

x28 [escape character-string] [noescape] [nuicud] [profile file-name] [reverse] [verbose]
no x28 [escape character-string] [noescape] [nuicud] [profile file-name] [reverse] [verbose]

escape character-string	(Optional) Specifies a character string to use to exit X.28 mode and return to EXEC mode. The character string can be any string of alphanumeric characters. The Ctrl key can be used in conjunction with the character string.
noescape	(Optional) Specifies that no escape character string is defined (user cannot return to EXEC mode). On the console line, the noescape option is ignored, and the default escape sequence is used (exit command).
nuicud	(Optional) Specifies the network user identification (NUI) data to not be placed in the network user identification facility of the call request. Instead it is placed in the call user data (CUD) area of the call request packet.
profile file-name	(Optional) Specifies using a user-configured profile of X.3 parameters. A profile is created with the x29 profile EXEC command.
reverse	(Optional) Specifies reverse charges for outgoing calls made from the local router to the destination device.
verbose	(Optional) Displays optional service signals such as the called DTE address, facility block, and CUD.
