# Traveling Class Marks

## Description

Traveling Class Marks allow callers in a private network to access features and services based on the their own Class Of Service (COS), Class of Restriction (COR), and Interconnect Number, rather than on those of the incoming trunk on the remote system.

NOTE: On the remote system, the COR comparison and decision making only applies when accessing an outgoing Public trunk (that is. this remote system is a gateway node to the PSTN). The COR does not apply when accessing Internal trunks.

The TCM can be used

- for displaying or logging purposes by the remote system.

- to restrict or grant features and services.

- restrict calls from using a particular route out of the system.

- to disallow the caller to call a particular destination.

## Conditions and Feature Interactions

- TCM is available on systems with 3300 ICP Release 8.0 or higher software. Calls to systems that do not have the required software are processed as usual.

- For TCM to operate correctly,

- all systems within the cluster or network must have identical COR Group, COS and Interconnect Restriction programming. This can be achieved through System Data Synchronization.

- the link exiting MiVoice Business must NOT have 'QSIG Private Network Access' set to Yes in the link descriptor.

- All trunk types, including TDM and IP, that support the DPNSS protocol will support TCM.

- TCM are sent only if the calling or called party is either a set or an attendant console.

## Programming

- System Options form

- Set "Send Travelling Class Marks" to "Yes."

NOTE: Failing to add a suite to the Guest Rooms form will cause calls to and from non-primary suite members to use the member's COR, COS and Interconnect Restrictions instead of those belonging to the primary suite member as intended by the TCM feature.
