PAD Switching

The DTC PAD switching allows remote users who enter a full address at the PAD

prompt to be routed directly to the associated host system from the PAD prompt. Other

calls are routed to the DTC user interface. Alternatively, a remote user can enter the

DTCs X.25 address, and then connect to a system through the DTC user interface in the

same way as local users, using the command connect <nodename> or connect <IP

address>.

The system node name can be named using either IP address or an MPE nodename.

Example of PAD switching

In this example:

• The DTCs X.25 board has the X.25 address 123456

• MPE_A has the X.25 subaddress 01
