XID

  To add an entry, click on the Add button.
  To delete an entry, select it, then click on the Delete button.

ID

  This is the poll address of the controller. This value is defined automatically, however, if can be changed if necessary.
  Range: 01 -- FF

NAU Name

  This name is optional. It enables you to assign a unique name to the DSPU. Each NAU name must be unique on the unit.
  Range: Up to 8 characters (A-Z, 0-9, @, # , or $)

XID

  If you configured an XID for the DSPU on the remote end, this field must reflect that value. If you did not assign an XID on the remote end, leave this field blank.
  Range: 8 hexadecimal numbers

Source Port

  Click inside this field and select the port through which the DSPU communicates with the host device. For instance, if the PU communicates with the host device through the LAN, you should select the LAN port.
  Range: LAN or ports 1 -- 8

Source DLCI

  If the PU communicates with the destination through the WAN, and is using a specific DLCI, enter the DLCI in this field.
  Range: 16 -- 1023

Source MAC Address

  If you are using XIDs, you may leave this field blank. If you are matching MAC and SAP addresses, you need to enter the MAC address of the source unit.
  Range: 400000000000 -- 7FFFFFFFFFFF

Destination SAP

  This value represents the SAP address of the destination device.
  Range: 04 -- F8 (in increments of 4)

Source SAP

  This value represents the SAP address of the source device. If you have more that one LAN PU mapping to the same destination, you need to change this value so that the DSAP and SSAP combinations between two units remains unique for each LAN PU.
  For instance, if you add another LAN PU whose source is unit A and destination is unit B, by default, you will have two mappings with 04 04 DSAP/SSAP combinations. Even though the second LAN PU shares the same source as the first LAN PU, you still need to change the SSAP value to 08, or some other unique value. In short, the DSAP/SSAP combinations must be unique for all LAN PUs with the same destination.
  Range: 04 -- F8 (in increments of 4)

Destination Port

  Click inside this field to select the port through which the logical PU communicates with the destination device.
  Range: LAN, or ports 1 -- 8

Destination DLCI

  If the logical PU communicates with the destination device through the WAN, and is using a specific DLCI, enter the DLCI in this field. If you are implementing session resiliency, you need to enter your primary DLCI in this field.
  Range: 16 -- 1023

Destination Name

  If the unit is using XID mapping, and is answering the call, you may leave this field set to None. If the unit is originating the call, or using MAC/SAP addressing (no XIDs), you need to select a destination.
  If the destination is a Host, or some other unit that cannot be configured through this management program, you can add it through the Destination Editor.
  Range: Any destination available from the list.

Destination Source SAP

  The editor automatically assigns this value once a destination is defined. If necessary, you may change this value to reflect a different SAP.
  If you have allowed the configuration editor to assign the SAPs automatically, you do not need to change this value.
  Range: 04 -- F8 (in increments of 4)

Advanced

  Click on this button to define parallel and alternate routes for the selected PU. This feature also enables you to enable dial backup features on a per-PU basis.
