What device initiates a session in an X.25 network?
A. DTE
B. DCE
C. PSE
D. PAD
Answer / guest
Answer: A
A DTE initiates a session in an X.25 network. The correct
order to establish a virtual circuit in an X.25 network is:
1.)The source DTE sends packet to the local DCE
2.)The local DCE packet binder sends packet to the closest
PSE (Packet Switch Exchange)
3.)The PSE (Packet Switch Exchange) passes the packet to the
next remote DCE
4.)The remote DCE examines the packet header of destination
DTE
