Sage Instruments 930i Communications Test Set
Remote Control
Operation
Reports If the 930i has sent the host computer an ALERT, it will respond to the [W]
command with a report concerning what caused the ALERT. This could be a
PCM error, a completed Receive Record sequence, Wink Timing information,
105 test results, or some combination of the four.
Section 6-4.4 contains further
details of Report Formats. When used as a near-end responder (OPTION MENU
#:26, ROTL RESPONDER), the 930i will send an alert (bell) at the completion
of each test.
6-6.5 Display Line Formats
A Display Line is always 50 characters long, terminated by a carriage return and line feed. The first 40
characters of a Display Line mirror the display on the front panel of the 930i. The next 4 characters are
ASCII blanks. The next character shows originating supervision. The next 4 characters are ASCII
blanks. The last character shows terminating end supervision.
In the following examples of typical PC screen displays, numbers are denoted by a single [N] for each
possible digit. Each [N] may stand for any number. Signed numbers are shown preceded by a [+] or
[–] character.
Leading zeros are printed as blanks and trailing zeros are printed as zeros. The digit to the left of the
decimal point will always be printed, including leading zeros. The sign of the number will always be
printed to the left of the first non-blank digit. Uppercase [O] or [T] indicates an off-hook condition;
lowercase [o] or [t] represent an on-hook condition. These symbols are not seen on the 930i display.
Typical example displays of the computer's CRT are below:
