Layer 2 Mode Defines the value of the HDLC address field in
the transmitted command frames (Layer 2).
Possible values:
■
auto (default value): The selection made for
Connector is accepted.
You can usually accept this setting, e.g. for
access to a public data network such as
Datex-P.
■
dte: The address field has the value for
DTE.
■
dce: The address field has the value for
DCE.
Interface Leads Defines whether X4000 checks the status of
the interface lines. The same value should be
set for both connection partners. Possible
values:
■
enabled: The status of the signal line (I for
X.21, CTS for V.35, V.36 and X.21bis) is
checked and transferred as L1State.
■
disabled (default value): The status is not
checked; the physical line is always up. In
this setting, you should monitor the
interface line in some other way, e.g. with
PPP Keepalive.
