Superloop Network Configurations
The Superloop Network Card combines four regular network loops to make
120 timeslots available to PE cards housed in Intelligent Peripheral
Equipment Modules. This increased bandwiath and larger pool of timeslots
increases the network traffic capacity by 25% for each 120 timeslot bundle.
The NT8D37 Intelligent PE Module is divided into segments of 4 card slots.
These segments are numbered O-3. Segment 0 consists of PE slots O-3,
segment 1 consists of card slots 4-7, segment 2 consists of card slots 8-11,
and segment 3 consists of card slots 12-15.
A Superloop may be assigned from one to eight Intelligent PE segments. A
number of different superloop to segment configurations are possible. The
configuration chosen will depend upon system traffic requirements and the
specific PE cards used. Figures 4 through 9 illustrate different superloop to
segment configurations. Note that the TN to Timeslot concentration figures
(figure 3) are nominal, and may vary from segment to segment.
