Japanese to English Tech/Engineering IT (Information Technology) banking

Note: 全銀協 = JBA (Japanese Bankers Association)

I have a document about a new Banking Connection System to be introduced to a manufacturing company. Under this System, the company will be connected to 4 major Japanese financial institutions.

The document has many references to 「全銀」 and a single reference (later) to 全銀協.
My question: is 全銀協 commonly known simply as 「全銀」 in Japan? I find this very ambiguous as to whether 全銀 is referring to the JBA or simply to the 4 banks in my document (although I wonder if then they might have said 「全４銀」??? The banks are _never_ referred to individually in my doc, only collectively.

Some context:
