Enterprise Edge security

Programming provides several ways of protecting Enterprise Edge from

unauthorized access or use. For more information on features that provide restricted

access to your Enterprise Edge system, refer to:

• Class of Service on page 333

• Restriction filters on page 333

• Direct inward system access (DISA) on page 335

Class of Service

Class of Service (COS) refers to the capabilities that Enterprise Edge provides to

users who access the system from the public or a private network. The COS

includes:

• filters that restrict dialing on the line

• an access package, which defines the set of line pools that may be accessed and

whether or not the user has access to the paging feature.

The COS that is applied to an incoming remote access call is determined by:

• the filters that you apply to the incoming trunk

• the COS password that the caller used to gain access to Enterprise Edge.

In cases where DISA is not automatically applied to incoming calls, the remote

caller can change the COS by dialing the DISA DN and entering a COS password.

To program COS passwords, see COS Passwords on page 160.

Restriction filters

Restriction filters can be used to restrict the numbers that may be dialed on any

external line within Enterprise Edge. Up to 100 restriction filters can be created for

the system. A restriction filter consists of up to 48 restrictions and their associated

overrides.

To restrict dialing within the system, you can apply restriction filters to:

• outgoing external lines (as line restrictions)

• telephones (as set restrictions)

• external lines on specific telephones (as line/set restrictions)

Restriction filters can also be specified in Restrictions service for times when the

system is operating according to a schedule. See Restriction service on page 141

and Restriction filters on page 124 for more details. Dialed digits must pass both the

line restrictions and the set restrictions. The line per set (line/set) restriction

overrides the line restriction and set restriction.

Line and set restrictions are shown in Line restriction example on page 334 and

Remote line restriction example on page 334.
