NT5D21 Core/Network module
This module provides common control and network interface functions in CS 1000M SG, CS 1000M MG, CS 1000M HG, Meridian 1 Option 51C, Meridian 1 Option 61C, and Meridian 1 Option 81C.
Two Core/Network modules are required in the CS 1000M SG, CS 1000M MG, Meridian 1 Option 81C, and Meridian 1 Option 61C systems to provide redundant common control operation. If a failure occurs in one module, the function is transferred to the appropriate circuit cards in the other module without a loss of service. One Core/Network module is required in the CS 1000M HGor Option 51C system.
One section of this module houses the common control complex (CPU, memory, up to three CNI cards, and mass storage functions). The other section supports a Conference card, one Peripheral Signaling card, one
Note: CNI card slots 13 and 14 remain empty.
Each Core/Network module houses up to four NT8D04 Superloop Network Cards for a total of 16 network loops. Superloop Network cards are cabled to the backplane of an IPE module. In a typical configuration, one conference/TDS card is configured in the module, leaving 14 voice/data loops available.
Figure 8 "NT5D21 Core/Network module" (page 27) shows the cards housed in the NT5D21 Core/Network module as configured for Meridian 1 Option 61C.
