This attribute specifies the mode of interoperability between the
Frame Relay and ATM connections regarding upper layer protocol
encapsulations. This is used as the default for all the connections on
the interface.
When translationMode is selected, the interworking function
performs translations between RFC1490 and RFC1483
encapsulated headers. This includes routed protocol translation,
bridged protocol translation, and connection oriented protocol
translation (except for RFC 1490 connection oriented protocol
without RFC 1490 header, which is done in speTranslationMode).
A value of transparentMode indicates that the interworking
function is forwarding data without altering the upper layer user
protocol encapsulation. Use transparent mode when the upper layer
user protocol encapsulation methods are compatible between
terminal equipments.
A value of speTranslationMode indicates that the interworking
function performs single protocol translation between RFC1490
with no header and RFC1483 encapsulated packets.
