Configuring ISDN Call Destinations 119
a call destination entry without having to delete it from the
WAN Call Directory.
Default: Enabled
Options: Enabled, Disabled, Time Restricted
Enabled means that outgoing and incoming calls to and from
this destination are allowed.
Disabled means that no outgoing call can be done using this
destination and incoming calls from this call destination are
rejected. If this call destination´s CLI number is in the CLI List,
incoming calls from this site are rejected on the D channel; i.e. no
charges accrue for the caller.
Time Restricted lets you enable and disable the Call Status at
specific times. Thus, you can disallow incoming and outgoing
calls at the weekends, for example, or configure a call destination
for occasional uploads or administration purposes. When a
connection to this call destination is active and the Call Status
changes to "Disabled", the connection is automatically termi-
nated. A configured backup call destination would then be
activated.
For information on configuring Time Restrictions, see Step 29
below.
6. Check the Call Type .
This parameter lets you specify how the outbound connection is
maintained on the network protocol level.
Default: On Demand
Options: On Demand, Permanent
An on-demand connection is activated by data and terminated
logically and physically when the Disconnect Timeout is
reached. The Inactivity Timeout controls the physical connection.
On Demand is the correct setting for circuit-switched lines.
A permanent connection is kept active continuously by reconnec-
ting whenever the link goes down. The underlying physical
connection is controlled by the Inactivity Timeout.
For D64S, DS01 and DS02, you have to set the Call Type to
Permanent and set the Retry Mode (see Step 45) to an appropri-
ate value.
