Centralized System Maintenance and Administration
A centralized system maintenance and administration facility can be designated at one node in
the network allowing all nodes in the CCIS network to be maintained from a single location.
This reduces travel costs and maintenance times. All system messages, fault data, and cyclic
diagnostic reports will be transmitted over the D channel to the designated central facility as
shown in the following diagram. The individual system messages and diagnostic data of each
node can be easily identified, since each system node has an assigned name allowing
messages from multiple sites to be separated. Additionally, each node will buffer and output
system messages and diagnostic data to a local printer at the node generating the information.
This feature applies to the 2400s sharing a network with 2000s. The 2000 IPS will pass fault
information originating from the 2400s through to other 2400s. When a
U NIVERGE NEAX
2400
IPX is in the network, the 2000 IPS will send its fault data to the 2400 IPX designated as
Central Fault MAT.
System administration also benefits from the ability to perform high speed adds, moves or
changes from the centralized facility for any node in the network without the addition of costly
peripheral equipment. The costs savings in this area are immediately realized.
