REMOTE CONTROL STATUS
REGISTERS
The INTERCEPTOR 147 uses a set of internal registers,
queues, and buffers to store information about test status,
line conditions, alarm conditions, error conditions, and
print information. The user may access this information
by using INTERCEPTOR 147 status queries.

The INTERCEPTOR 147 has six groups of registers:
Status Byte Register, Event Status Register, Test Summary
Register, Remote Alarms Register, AIS Alarms Register,
and Line History Register (see Figure C-1).

INTERCEPTOR 147 Registers
Each group of registers captures specific events. Within
each group of registers is a status register, composed of 8
bits, representing up to 8 events. When a specific event
occurs, the corresponding bit is set to 1. The user may read
each status register and interpret the bits to provide test
status information.
