Online Expansion and Reconfiguration

You can add a new node or new lines to a network or move an existing node to a

different location without disrupting network activity.

You can make changes to your Expand configuration online using the Subsystem

Control Facility (SCF) interfaces to the Expand and WAN subsystems. Table 2-1 shows

the online expansion and reconfiguration tasks that can be performed with these

interfaces.

The SCF interface to the Expand subsystem is described in Section 14, Subsystem

Control Facility (SCF) Commands. The SCF interface to the WAN subsystem is

described in the WAN Subsystem Configuration and Management Manual.
