24 System architecture
2 segments per Superloop
In this configuration, 2 segments are assigned to 1 Superloop (see Figure 5).
In cases where the segment is populated with NT8DO2AA Digital Line
Cards with no data TNs enabled, NT8DO3 Analog Line Cards, NT8Do9AA
Message Waiting Line Cards, or NT8D14AA or NT8D15AA Tnmk Cards,
the 2 segment per superloop configuration will provide a virtual non-
blocking (120 Timeslots to 32-128 TNs) environment (see Figure 2). For
instances where half of the data TNs on NT8DO2AA Digital Line Cards are
enabled, this configuration still provides a low concentration of TNs to
timeslots (120 Timeslots to 1% TNs) and a very low probability of
blocking. Two NT8DO4A.4 Superloop Network Cards and one
NT8DOlAD Controller-2 Card are used to implement a 4 segment per
superloop configuration.
