If this is a ML\EL,
The following conditions apply to this feature:
• The system requires an ONS/CLASS Line card, and the BCC III with a DSP module (single) in the same SX-200 ELx cabinet. LIGHTWARE 18 Release 2.0 or greater software is also required.
• The trunk side CLASS functionality requires a LS/CLASS Trunk card, LS/CLASS trunk module with the SPINE, T1 (ANI/DNIS), or ISDN BRI, PRI, and Network Gateway (CLID and CNID).
• The eight CLASS generators on the DSP module are assigned and released as they are required. The CLASS generators are only assigned while information transmits to the set.
• COS Option 502, Display ANI/DNIS/CLASS Information, must be enabled for the analog sets.
• COS Option 505, ONS Stations Support CLASS must be enabled.
• COS Option 507, Station/Set: Allow My Number to be Displayed controls whether or not the number of a station or set appears on another station or set on the same system. The blocking of the number works independantly of who is the caller and who is the called party.
If COS option 507 is disabled and Set A calls Set B, Set B will not see the number belonging to Set A. If Set B calls the front desk and requests to be connected to another guest and is transferred to set A, set B will again not see the number belonging to set A. The default for COS Option 507 is ENABLED (showing the internal number).
• COS Option 508, Station/Set: Show Internal Numbers on My Phone, overrides COS Option 507. COS Option 508 allows a station or set to always see the number of the other party. Administration telephones such as room service would use this COS option.
• The purchasable System Option 89, CLASS Functionality for ONS Sets must be enabled.
• The analog telephone must interface to the ONS/CLASS Line card to obtain the CLID information.
• The Calling ID of the originating outside caller is dependant on the programming of COS Option 273, Display Held Caller ID to ONS/CLASS, for the transferring party. The ONS CLASS set will display the caller ID of the outside original caller if the transferring party has COS Option 273 enabled (the default setting is disabled). If COS Option 273 is disabled for the transferring party or if the held party is an internal telephone, the ONS CLASS set will show the caller ID of the transferee i.e. attendant, automated attendant, voice mail etc.
• SUPERSET telephones with a SIM2 do not support CLASS.
• A CLASS command clears stored calling/called numbers and names on ONS sets when a hotel-guest checkout occurs.
• Third-party telephone sets may not provide the expected functionality.
• Telephones with COS option 505 enabled, cannot take part in a Message Lamp Test. CLASS protocol controlling the message waiting lamp interferes with this.
• An ONS CLASS set will not display the name of the caller after a Call Park System Orbit retrieve.
• The timing co-ordination for the name and number on BRI and PRI trunks is controlled with COS Option 813, Delay ONS Ring - Wait for Network Name (0-6 s).
