Channel Setup
ENCAP_HDLC_RFC2364
This encapsulation type converts HDLC to ATM and vice-versa. ENCAP_HDLC_RFC2364 maps one
HDLC VC to one ATM VC. Choose this encapsulation type if your LAN router provides PPP over HDLC
service and the remote peer provides PPP over ATM.
Refer to
RFC 1662
for more information on PPP over HDLC and
RFC 2364
for more information on
ENCAP_HD
LC_RFC2364
.
PPP
This encapsulation type supports ATM (PPP over ATM). Choose this encapsulation type if you want to set
up a channel for remote management. This channel will be used exclusively for remote management and
cannot be used to transfer data. The Prestige allows you to configure one channel for remote configuration.
PPP over ATM terminates on the Prestige. For more information, refer to
section 3.4.
