Night Station Service directs incoming calls for the attendant to designated extensions. To activate Night Station Service, attendants press the Night button on the principle console, if there is an inactive night console. If the night station is busy, calls including emergency attendant calls, receive busy tone. Calls do not queue for the attendant.

When Night Station Service is active, the system routes the incoming calls to the attendant as follows:

• Direct Inward Dialing (DID) Listed Directory Number (LDN) calls are routed to a designated DID-LDN night extension.

• Internal calls route to the DID -LDN night extension, unless you administer the system so only DID-LDN calls can route to the LDN night extension.

• Non-DID calls are routed to the night destination that you specify for the trunk group or for the individual trunk. If you do not specify a night destination, the calls route to the DID-LDN night extension.

You can assign a unique extension as the night destination for each incoming central-office, foreign-exchange, or 800-Service trunk group. Both the extension assigned as a trunk group’s night destination and the DID-LDN night extension can be phones or answering groups (such as DDC group, UCD group, or terminating extension group (TEG).
