Invoking Routing Control
The alternate NCOS numbers associated with special TOD schedule 7 are
normally invoked when the time specified for TOD schedule 7 corresponds
to the time in the SL-1 system clock. Additionally, the alternate NCOS
numbers can be scheduled for implementation (through SL-1 service change)
for the full 24-hour period of specified days of the week. This capability
enables network-access capabilities to be changed automatically on
weekends or company holidays.
The SL-1 attendant can also manually invoke the special TOD schedule
through use of a routing control (RTC) key on the console. Pressing the RTC
key lights the associated lamp, and invokes the special TOD schedule. To
deactivate routing control, the RTC key is pressed again. The associated
lamp goes dark and normal TOD schedules are once again in effect.
Authorization code can be used to override the restrictions imposed through
routing control. If a user enters a valid Authorization code (AUTH) , the
NCOS number associated with the AUTH is applied for the duration of the
call.
Network traffic measurements
The Network Traffic (NTRF) feature provides traffic measurement data
related to network performance and network traffic at each SL-1 Node and
SL-1 Main. Effective use of this data enables the network communications
manager to assess the effectiveness of the network, and to identify specific
areas of network operation where improvements are warranted.
Areas of network operation that are measured include NCOS, OHQ, CBQ,
and routing. These measurements are provided in addition to existing
non-network traffic data in Traffic measurement formats and output
(553-2001-450).
TFN001 routing measurements
The routing measurements provide data related to route list utilization. A
route list is a list of alternate trunk routes which are identified through
interpretation of the dialed number. For each defined route list, these
measurements show:
— how often the list was used
