static route
A static IP route is a provisioned IP route. The provisioning information
includes a destination IP address, subnet mask, cost of the route (metric),
whether it is protected or not, and one or more NextHops on the path to
destination of the IP route
statistic
Nortel Multiservice Switch system has three categories of statistics, which
consist of counters and gauges (for example, byte counts and processor and
link utilization):
• statistics for network engineering and long-term planning activities (these
are gathered at regular intervals and are usually processed offline)
• real-time statistics for day-to-day troubleshooting activities (these are
required in when problems arise)
• statistics for billing and customer reporting activities for each call
statistics collection interval
The 15-minute interval during which spooled statistics are collected. This
interval is based on network time and occurs across the network on the hour
and 15, 30, and 45 minutes past the hour.
status
An operational value giving different information than the state value.
STM-1
Synchronous transport module level 1. Equivalent of STS-3/STS-3c.
stratum-3 clock
Timing sources for networks are often described in terms of stratum levels.
The different stratum clock sources define different levels of accuracy. A
Stratum-3 clock has an accuracy of ±1.6 bits in 10
9
.
STS-1
Synchronous Transport Signal level 1. The basic logical building block signal
with a rate of 51.840 Mbit/s.
STS-N
Synchronous Transport Signal level N. The signal is obtained by byte
interleaving N STS-1 signals together. The rate of the STS-N is N times
51.840 Mbit/s.
stub network
An OSPF network with only one OSPF router.
