PBXs were economical for some very small businesses in need of features that most key systems did not provide, such as restriction and least cost routing
You question is far from clear, but nuclear weapons use a high explosive "trigger". The chemical explosives serve to crush nuclear materials into a very dense form, starting a nuclear chain reaction. There have been many different explosives used for that purpose- explosives used in modern day weapons is rather classified, and we don't discuss classified materials here.The chemical explosives used in most nuclear weapons since the 1960s have been PBXs (Plastic Bonded Explosives). However there are literally many dozens of different PBXs, each having different properties. PBXs were selected for safety: they are insensitive to shock or fire.I am not sure what you mean by "cycle". The only thing I know of with a name like that was cyclonite, an explosive used in some nuclear weapons in the 1950s, but it is very shock sensitive and thus unsafe.Some unclassified information on nuclear weapon explosives is available in Chuck Hansen's work Swords of Armageddon.

Iron is used in the production of steel. Copper is used in electrical wiring. Gold is used in jewelry and electronic components. Diamond is used in cutting and drilling tools. Silver is used in photography and currency.
Borax decahydrate is commonly used as a cleaning agent and laundry booster. It can also be used as a pesticide, fungicide, and herbicide. Additionally, borax decahydrate is used in various industrial processes such as metal refining and textile manufacturing.
It is a standard feature of many PBXs
Private branch exchanges (PBXs) are used for internal and external voice traffic
The distinction between the KTSs and PBXs became more blurred as technology brought more intelligence to the KTS
Private branch exchanges (PBXs) are used for internal and external voice traffic. Business customers purchase PBXs because it provides features on the line, and keeps call records on each individual line. It connects to the local telephone end office switch through shared trunks, thus reducing the number of telephone lines needed to supply dial tone to all of the employees in the company.
To connect telephone company central offices (COs), To provide a path between switches, To connect PBXs
PBX systems uses PSTN lines to connect another PBX system over a long distance.

Analog PBX is telephone system that is capable of handling calls and phone logs. Digital PBX is a system bundle with phone capabilities, fax, and other internet features. Digital PBXs are usually interfaced with computers and are internet-based.
"A hosted PBX system delivers PBX functionality as a service, available over the Public Switched Telephone Network (PSTN) and/or the internet. Hosted PBXs are typically provided by the telephone company, using equipment located in the premises of the telephone company's exchange. This means the customer organization doesn't need to buy or install PBX equipment (generally the service is provided by a lease agreement) and the telephone company can (in some configurations) use the same switching equipment to service multiple PBX hosting accounts..." - Wikipedia.org
Information Technology is a 'classification' term that defines all components of the systems that gather, share and store information. A computer is a component of the 'IT' division. Other components are the Network devices (routers, switches, hubs, etc.), communication devices (Modems, PBXs, etc.), storage devices (optical drives, mass storage drives, back up units, etc.), etc.
