IBM SC30-3681-08 manual Syntax Enable DdnÐaddress-translations, Incoming-calls-barred, Lower-dtr

Con®guring the X.25 Network Interface

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 ddnÐaddress-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

Speci®es 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 ²disabled² (the default), the DTR signal will be raised when the interface is disabled.

If lower-dtris set to ²enabled,² the DTR will be lowered when the interface is disabled. This behavior may be desirable in situations where the interface has been con®gured 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

Speci®es 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 certi®cation, or the incoming-calls-barred or outgoing-calls-barred features.
