The class of restriction for a station user’s dialing

SLS uses the dial-pattern field as part of its ARS routing for station dialed calls that are to be directed to the other stations and to make outbound trunk calls. Make sure to synchronize your choice of station COR and dial-plan dial-type. The following figure illustrates the relationship between the set cor value and the set type (dial-pattern) value (configured in dial-pattern context). Note the following:

  • The outer boundary of a station’s COR class inherit all the properties of the class symbols encompassed by this class. For example, the local COR class is also able to dial the emergency COR.

  • COR set to emergency is the most restricted class. If a station's COR is set to this mode, the only calls that are allowed are those that have an emergency type identified in the ARS Analysis table.

  • COR set to internal enables the station to place calls to other stations supported by this gateway. The station is also able to dial calls that match dial patterns with dial-type set to emergency.

  • COR set to local enables the station to place calls that match dial patterns with dial-types set to local, operator, service, or hnpa. In addition, the station may place calls to the emergency and internal classes.

  • COR set to toll enables the station to place calls that match dial patterns with dial-types set to fnpa and natl. In addition, the station may place calls to the emergency, internal, and local classes.

  • COR set to unrestricted enables the station to place calls to any dial patterns that are not explicitly labeled as denied class within the ARS Analysis table. This class of COR effectively inherits the call permission properties of all the other classes.

  • The Emergency Transfer Relay (ETR) mode is basically equivalent to the unrestricted class. When power is lost and the gateway enters ETR mode, the station port is directly connected to the trunk port and receives central office dial tone directly. This ETR station port may dial any number that the central office dialing plan affords for this analog trunk.

Example

To set the restriction for a station user’s dialing to unrestricted:

Gxxx-001 (sls-station <extension>)# set cor unrestricted

1

As the class of restriction moves from emergency to unrestricted, each level increases the range of dialing abilities for this station. For example, toll level includes local, internal, and emergency.
