Acquire [Device] Poll List (acpl)
(Disruptive – DATAPHONE II APL Modems)
Use the acpl command to direct a COMSPHERE 3400/4400 Series modem, a COMSPHERE
3900 Series modem, a COMSPHERE 3600 Series Data Service Unit (DSU) with Multichannel
Multipoint (MCMP) capability or a DATAPHONE II modem, Shared Diagnostic Unit (SDU), or
DSU to poll all its tributary devices to establish a poll list. This command can also be sent to a
3400/4400 Series modem with a DBM.
Polling is the process by which alarms from devices in the network are automatically reported to
the NMS. Once a poll list is established for a device, the device monitors the devices on its poll list
for health and status.
NMS polls devices on the control channel. Those devices then poll devices downstream, and so on,
through the extended diagnostic network. A device always reports health and status of all devices
on its poll list to the device that polls it. Thus, NMS is able to obtain health and status for all
devices in the network by polling only devices on the control channel.
The acpl command automatically determines all devices directly downstream of the specified
device and adds them to the device’s poll list.
For most commands, NMS enables you to specify the destination for the command’s results and
schedule its execution. If the last page of the input form cannot accommodate the Destination for
results and Schedule execution fields, an additional page is provided. For a complete description
of these fields, refer to Chapter 1, Introduction.
