Number
A Packet Telephone Number identifies a node on an X.25 network. The address is a
series of one to fifteen digits. Every X.25 node has a Packet Telephone Number.
It defines the D-channel's DTE address for communication with the local packet
handler. This parameter allows the DIVAT/A to activate the D-channel during
initialization and give its address to the switch.
This value is assigned by your ISDN provider at subscription time.
