NTP Output Connector Modules
The NTP Output Connector modules provide an interface for all external signal
connections necessary for NTP operations (Figure 2-20). Two NTP Output
Connector modules are available for the Master shelf: a double-width Output
Connector module for Groups A, B, and C, and a single-width Output Connector
module for Group D. You can also use the single-width module in the 1–20 slot in
Group A, B, or C. One Output Connector module is available for use in an
Expansion shelf. Table 2-11 describes the LEDs on every module.
