Single-Line Telephones in Release 3.0 and Later
In Release 3.0 and later, only single-line telephones with positive disconnect
are fully supported as system telephones (any single-line telephones,
equipped with a ground-start button if necessary, can be used as PFT
telephones). Older single-line telephones can be used with Release 3.0, but
their operation is slightly different. Table 3-3 lists the single-line telephones
supported in Release 3.0 and later.
