HDLC Menu (VHSI Tree) > X.32 Services Group

(X.25)

Note:

The HDLC menu is only accessible through the Protocol page, when the protocol is set to X.25.

Service

Variations of the HDLC protocol expand upon the protocol to provide additional
information to the host and client systems.

Default: None.

• None: Standard implementation of HDLC.
• Eripax: A variation of HDLC made to work on Ericsson private networks. The ERIPAX

XID helps identify you to other network clients even when you are using a dial-up line.

• CCITT: A CCITT standard variation of the HDLC protocol providing parameters to

help identify you to other network clients even when you are using a dial-up line.

• Transpac: A variation of HDLC made to work on the Transpac network in France. The

Transpac ID and SID parameters identify you to other network clients even when you
are using a dial-up line.
