MIL-STD-188-154A
a. Knowing the status and quality of designated transmission links, trunks, circuits, and communications equipment.
b. Taking immediate action on any deterioration or failure within the communications system.
c. Restoring service expeditiously.
d. Responding to changes in mission requirements.
4.1.2.2 Network management. The traditional functions performed by TCFs support the broader goals of modern network management. As these traditional functions continue to become more automated, they will become more integrated into network management concepts. New installations should take into consideration automation when developing requirements. This will help to ensure a smooth transition. ANSI T1.210-1993 describes network management functions in terms of the five categories of the OSI network management model:
a. Performance management consists of a set of functions to monitor, evaluate, and report on the behavior of managed network elements.
b. Fault management consists of a set of functions to detect, isolate, and correct abnormal operations.
c. Configuration management consists of a set of functions to exercise control over, identify, collect data from, and provide data to network elements for the purpose of providing continuous operation of services.
d. Accounting management consists of a set of functions to measure the use of network services.
e. Security management is a set of functions to protect the network and systems from unauthorized access.
4.1.2.3 Relationships between facilities. The TCF serves as the focal point for connection to all types of users and systems. For example, the TCF provides the interface between long haul and tactical communications systems. TCFs typically provide major reconfiguration and restoral capabilities on a system basis. Within these large networks, many large subsystems (such as telephone switches, message switches, satellite terminals, etc.) are provided with their own control capabilities through a PTF. The PTF is normally associated only with that subsystem and contains the equipment needed to
monitor and test that subsystem for maintenance purposes. Many TCF and PTF telecommunications control and monitoring functions are commonly handled at CMCFs.
4.1.3 Organization. TCFs shall serve as the focal points for system control in long haul and tactical communications systems. TCFs shall be
