In FR PtoMP, there is an option to statically enter the DLCIs in association with a Protocol 
Manager, the physical port and MIB II, using the DLCI field in the Interface screen. If the DLCI is 
not static, it will be deleted if the Frame Relay switch determines that the DLCI has been 
eliminated. If the Frame Relay switch previously reported status on a DLCI, when it does not 
report the status of the DLCI, the DLCI and its associated information is deleted from the 
platform. Static entries are never deleted automatically. They must be deliberately deleted by the 
user. To enter a DLCI, it is set to “Inactive” and saved, but to delete a DLCI, it must be accessed 
and entered as “Invalid” and saved. 
The WAN configuration for Frame Relay is complete. Communications between the HSIM or 
CyberSWITCH and the service provider’s switch takes approximately one or two minutes to 
complete. A status of Inactive displays on a DLCI per DLCI basis by default until both ends of the 
DLCI are configured correctly. Once both end devices have negotiated link management with the 
switches, and are configured correctly on a DLCI per DLCI basis, the status field displays Active.
Configuration: DDS Service 
This section provides step-by-step instructions for connecting the HSIM or CyberSWITCH to a 
Digital Data Service circuit in a PPP or Frame Relay environment. This example assumes the setup 
similar to the one shown in 
 using two CSX400s with HSIM or CyberSWITCH 
modules installed.
