Network Attendant Service
Network Attendant Service schedule
The NAS schedule allows a prioritized list of attendant alternatives (attendant
locations) to be defined for up to 31 half-hour time periods. Each period can
have up to four alternate attendants defined against it. During one of these
time periods, a request for attendant service will use one of the alternatives,
according to the specified order - the first attendant alternate is attempted, and
if all attendants are in Position Busy, the following alternate in the sequence
is attempted, and so on.
If none of the attendant alternatives are available, an attempt is made to give
local attendant service, which may lead to the application of local NIGHT
service.
Night Service
Night Service treatment is defined individually for each node.
With the introduction of NAS routing, identifying whether or not a system is
in Night Service becomes more complex. Table 87 shows when Night
Service treatment is in effect. When all the conditions in a vertical column are
met, the system is considered to be in Night Service.
Status of local attendants
When NAS routing is active and there is an available attendant at the local
switch, the call terminates at the local attendant, if one is available. If a local
attendant is not available, the call may either be placed in the local attendant
queue (if the Call Waiting threshold has not been exceeded and the console
Call Waiting lamp is not flashing), or may receive local NIGHT service.
