There is no additional Night Service functionality provided for Attendant Vectoring. Night service routing can be provided using the existing night station service in conjunction with Attendant Vectoring. All existing night service rules remain in place, for example, night console service supersedes night station service, which supersedes TAAS. Attendant group calls are not redirected to Attendant Vectoring when the system is in night service unless a night console is available. Otherwise, the calls continue to be redirected to the applicable night service processing. To achieve Attendant Vectoring for calls when the system is in night service without a night console, the night station service extensions must be Attendant Vectoring VDN extensions.
