Hardware architecture 41
Superloop network configurations
By combining four network loops, the superloop network card makes 120
timeslots available to IPE cards. Compared to regular network loops, the
increased bandwidth and a larger pool of timeslots increases network
traffic capacity for each 120-timeslot bundle by 25 percent (at a P0.1 grade
of service).
The NT8D37 IPE module is divided into segments numbered 0–3 of four
card slots each (see
Figure 15 "Superloop segments in the IPE module"
(page 41) ). Segment 0 consists of slots 0–3, segment 1 consists of slots
4–7, segment 2 consists of slots 8–11, and segment 3 consists of slots
12–15.
Figure 15
Superloop segments in the IPE module
A superloop is made up of NT8D04 Superloop Network cards, NT8D01AC
or NT8D01BC Controller-4 or NT8D01AD Controller-2 cards, and from
one to eight IPE segments. The NT8D01BC Controller-4 replaces the
NT8D01AC and NT8D01AD Controller cards for replacements and new
installations.
A number of superloop-to-segment configurations are possible:
• one segment per superloop requires four superloop network cards and
one controller-4 card
•
two segments per superloop requires two superloop network cards and
one controller-2 card
