Setting Up a Call
Before making a remote connection, type a telephone number into the Phone
Number field, or choose Phone Book to access the Phone Book box to get the
number. See
Configuring a Device Phone Directory in Chapter 4, Configuration,
for additional information about the Phone Book.
Once you enter a telephone number, the Dial button is enabled. Before choosing
Dial, ensure that the correct phone number is selected.
Within the Type Of Dial box, select either the Normal or Maintenance option
button for devices other than DSUs. DSUs do not support a maintenance call. For
all other devices, use Maintenance for a direct connection between NMS and the
device, bypassing the DTE.
Using the Maintenance connection causes NMS to use the device’s primary
channel for diagnostic purposes. This enables higher data transfer rates as may
be required to download firmware or options to a remote device.
To place the call, choose Dial. If the remote device does not answer, a dialog box
appears indicating the cause of the problem. Once the connection is made, Dial
changes to Disconnect. Choose Disconnect to cause the local device to hang
up.
If you select a remote dial device, a list box of all the available local devices
appears. If you do not make a selection from the list box, a dialog box will appear
with a warning to select a local device to place the call. If Cancel is selected, the
Dial button is disabled until another device is selected.
Once the call is connected, the Dial changes to Training until the remote device
is logically connected. Training then changes to Disconnect. If you close the dial
window before a logical connection is established, you will receive a warning that
the device is not connected. If you close the window, the device will be
disconnected.
If the device is on a leased line, you can choose Dial Test to have the DBM place
the call. However, once the call is established, no further actions are performed.
The call is treated as a normal call.
If the device is a 2400 or 3800 Series leased-line model operating in the Lease
mode, or a DSU and a dial connection is made using the Dial button, the Dial
Standby button is enabled. To switch the device from dial to leased line, choose
Return to Lease.
If the device is a DSU and a dial connection is made using the Dial button, the
Dial Standby button appears in place of the Dial Test button. The Dial Standby
button changes to Return To Dial. To switch the device back to the DDS facility
and maintain the DDD connection, choose Return to Dial.
To return a 3800 Series device to the dial line, choose Return To Dial.
Disconnecting the device (choose Disconnect) causes it to automatically return to
the lease line.
To return a DSU to the dial line, choose Return To Dial. Disconnecting the device
(choose Disconnect) causes the device to be switched from a DDD to a DDS
facility.
