ABSTRACT: The 97A, 97B, and 97AB connecting blocks are 8-wire modular data jacks that provide an interface connection to the switched network for
data modems registered as either Fixed-Loss Loop (FLL) or Programmable (PROG). To prevent accidental switching from FLL/PROG, the
97A/AB type units have a select switch that is mounted to the printed circuit board assembly.
This Technical Reference (TR) provides the Telcordia view of generic requirements for 97A, 97B, and 97AB type Data Jacks (Connecting
Blocks) used with data equipment. The document includes the recommended test methods for comparing these products against the stated
