X.21 |
|
Defines the physical interface between a DTE and a DCE of a public
data network where the access to the network is made over synchronous
digital lines. |
|---|
|
X.25 |
|
Defines the interface between a DTE and a DCE for packet mode
operation on a Public Data Network (PDN). |

|
X.25 address |
|
The X.25 address provided by the network administration if you are
connected to a Public Data Network (PDN). |
|---|
|
X.25 address key |
|
An X.25 address key is a label that maps a node's IP address to its
X.25 address and its associated X.25 parameters. You have a combined
maximum of 1024 X.25 address keys in the SVC and PVC path tables.

X.25 LUG address |
|
X.25 address of a node belonging to a LUG. |

|
X.25 XL System Access |
|
he software that works in conjunction with the DTC/X.25 Network
Access software to provide MPE XL access to X.25. The software resides on
an HP 3000 host and is configured through use of NMMGR. To configure
access to an X.25 network, you must configure two software components, the
X.25 XL System Access and the DTC/X.25 Network Access (residing on the
Datacommunications and Terminal Controller and configured at the OpenView
Windows Workstation). Together, these two components provide a network
connection on HP 3000 systems to private and public X.25 packet-switched
networks PSNs). |
|---|
|
X.29 |
|
Defines the interface for data exchange between a packet-mode DTE and
a remote Packet Assembly/Disassembly (PAD) facility over a packet
switching network. |
|---|
|
X.3 |
|
Defines the user facilities that should be internationally available
from the packet assembler/disassembler (PAD) facility when this is offered
by a public data network. |
