(a) Maintenance Functions:
The thumbwheel switches may be (
used in conjunction with the test line to select receivers and
speech paths. The top two switches are used to select a re-
ceiver by setting the switches to the last digits of the required
receiver equipment number (even numbers only, 90-20). If set
to 99, any free receiver will be selected. The bottom two
switches are used to select a speech path (01-31 for speech
paths, or 32 for the Music-on-Hold speech path). If set to 99,
any free speech path will be selected.
(b) Programming Functions: The console that may enter pro-
gramming is defined.
(c) The Customer Program Dump/Load Function: Requires the
switches to be set to 5623 to initiate a
load
from an external
storage device.
4.33 Scanner Digit Display. The Scanner Card (position 19, shelf 1)
contains a 2-digit display which is used to display faulty card
positions and may
also
be used in conjunction with the test line to
display the status of selected circuits. The 2-digit display should al-
ways
be read from top to bottom. The display will show the position
number of the faulty card (01-22 for equipment shelf 1 and 31-42 for
equipment shelf 2). When used in conjunction with the test line, the
display shows the status of the receiver and/or the speech path which
has been selected. The top display shows receiver status and the
bottom display shows the speech path status. The displays used are
shown in Table 4-2.
