These systems feature a dual Pentium Processor with standby processing capability, two Core/Net modules installed side-by-side, and two or more network groups. The Core/Net modules provide the first network group, and network module pairs provide additional network groups.

These systems support up to eight network groups, as shown in Figure 3 on page 42. Fiber Network Fabric provides complete non-blocking communication between the network groups, eliminating busy signals for network-blocked calls between groups.

Figure 7 on page 47 shows a multi-group system with four network modules. If the ceiling height is too low for the four-tier column, a three-tier column can be used, as shown in Figure 8 on page 48.
