Access RestrictionsOverview

• Providing ability on VxWorks devices to restrict access on port basis; Linux OS built-in access restriction mechanism (i.e., IP table filtering) for port filtering. (New in 6.0)

• Content• Built in mechanism to restrict system access to

CS1000 system components • Protect CS1000 components from non-desirable

communications, through the ability to restrict access to these components.

• Restrict access to specific ports on the CS1000 components, that are allowed access to the system components.

• Example: Reject Ports not in use

• Value• Allows capability to shut down access to

unwanted, insecure protocols, including from restricted entities

• Provide integrated protection from Denial of Service Attacks

• Eliminates the need to install and maintain a separate entity to provide server protection

Calling Line Identification Display Example of Enhancement C in R6.0

• Set A calls Set B over a TDM or IP trunk.

• Set A restricts its number being displayed on set B (CPP (Calling Party Privacy) feature).

• CLID of the call sent/received would have Presentation Indicator = restricted.

• Set B is a high priority user (911 station, for example) and needs to see Set A’s number even though PII = restricted.

• Earlier only routes using one of the North American ISDN interfaces had a prompt PII to override the restriction on incoming route basis and display the calling party number

VNR Enhancement Feature

• Provides correct call clearing treatment for vacant number calls over an IP domain

• Provides flexibility to perform MCDN Alternate Routing (MALT) on the Call Server for an additional 10 causes (user defined) when the call is routed by VNR to the IP network

• The vacant number treatment is provided to the call when the call tries at least one time to route over an IP route.
