MIL-STD-188-154 Subsystem, Equipment, And Interface Standards For Common Long Haul And Tactical Telecommunications Control FacilitiesThis standard establishes physical and functional interface requirements for long haul and tactical telecommunications control facilities formerly technical control facilities in the Department of Defense DoD. As used in this standard, the term telecommunications control facility TCF includes patch and test facilities PTFs and interfaces to locations that provide centralized monitoring and control functions for other telecommunication locations.

designed to enable system control personnel to effectively exercise assigned responsibilities.  TCFs may perform both Defense Communications System (DCS) and non-DCS system control functions.

4.1.4   Design baseline.  The ultimate goal of the design baseline criteria is to establish an operational environment to optimize circuit quality, reliability, and restoration.  Primary consideration shall be given to the following:

a.     Capability to determine, log, and report status information of circuits, links, and trunks within the assigned area of responsibility by providing orderwire circuits, status monitoring, and quality monitoring equipment.

b.     Rapid restoral and rerouting on a priority basis in accordance with established procedures.

c.     Interface of circuit segments.

d.     Quality control and fault isolation capability including incorporation of test points to allow for the rapid test and replacement of circuit segments or elements at all levels in the communication hierarchy.

e.     Use of automated telecommunications control test and monitoring equipment.

f.     Voice and data interface requirements with other system control elements.

4.1.5   Major elements.  The facility may include, but is not limited to:

points.

a.    Digital and analog equipment with automated and manual access

b.    Conditioning capabilities.

c.    Orderwire circuits and intercommunications systems capabilities.

d.    Circuit distribution frame capability.

e.    Internal alarm system capabilities.

f.     Power sources - alternating current (AC) and direct current (DC)

capabilities.

g.    Communications security capabilities.

h.    Digital signal timing.

4.2      General considerations.  The following provisions shall apply to long haul and tactical TCFs.
