Communication Server 1000M and Meridian 1 Large System Installation and Commissioning
Meridian 1 PBX 81C and CS 1000M MG
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.
