Enable
Use the enable command to enable DDN address translations, interface resets, or
the incoming-calls-barred, outgoing-calls-barred, and lower-dtr features.
Syntax:
enable
ddn—address-translations
Note: Enabling ddn-address-translations is no
longer allowed. This feature defaults to
enabled when the national personality
selected is DDN, and defaults to disabled in
all other cases.
incoming-calls-barred
lower-dtr
outgoing-calls-barred
incoming-calls-barred
Specifies that the router will not accept incoming calls. The default setting
for this parameter is disabled or
off
, which allows incoming calls.
lower-dtr
This parameter determines the way the data terminal ready (DTR) signal is
handled for leased serial-line interfaces that are disabled. If this parameter
is set to ″disabled″ (the default), the DTR signal will be raised when the
interface is disabled.
If
lower-dtr
is set to ″enabled,″ the DTR will be lowered when the interface
is disabled. This behavior may be desirable in situations where the interface
has been configured as an alternate link for WAN Reroute and the interface
is connected to a dial-out modem which maintains its dial connection based
on the state of the DTR signal.
When lower-dtr is enabled and the interface is disabled, the DTR signal is
low and the modem keeps the dial connection down. When the interface is
enabled, due to a WAN Reroute backup scenario, DTR is raised and the
modem dials a stored number to the backup site. When the primary
interface is restored, the alternate interface is disabled, DTR is lowered,
and the modem hangs up the dial connection.
The following cable types are supported:
RS-232
V.35
V.36
The default setting is disabled.
outgoing-calls-barred
Specifies that the router will not allow outgoing calls. The default setting for
this parameter is disabled or
off
, which allows outgoing calls.
Disable
Use the disable command to disable DDN address translations, interface resets as
part of network certification, or the incoming-calls-barred or outgoing-calls-barred
features.
