If the MLIO package is not restricted and a 7-bit TTY is used, the 8-bit
supported characters cannot be printed correctly. Instead, the service change
administration interfaces may print garbage characters and/or the interfaces
may lock.
When the MLIO package is not restricted, the system sends the valid 8-bit
characters to the TTY, rather than the underscore characters. With the MLIO
package equipped, it is assumed that the TTY is capable of handling 8-bit
characters. If the TTY is capable of entering the “¿” 7-bit character and all
other supported 8-bit characters directly, then these characters are accepted
by the system, without using the hexadecimal values for the Terminal Text
Broadcast customized text. The hexadecimal values can, however, still be
used for entries.
The “!” character cannot be entered directly from the TTY keyboard. It can
be entered, however, through character-by-character input
(
IDLE_DISP_CHAR nn prompt in Overlay 17), using its hexadecimal value.
When the system does not recognize a temporary power outage on a Meridian
Modular set, the screen may remain blank until the custom display
information, along with the time and date information, is downloaded again.
If the new Electronic Brandlining ISM parameter has an invalid value, the
default display is shown. In this case, conversion should have defaulted the
NORTEL_BRAND to YES, and as long as this prompt has not been changed,
“NORTEL” is displayed.
If the Electronic Brandlining ISM parameter is set to the Terminal Text
Broadcast value and the customized text string is configured as “NORTEL”
or blank, the NORTEL_BRAND option does not apply. The
NORTEL_BRAND option only applies to toggles between “NORTEL” and
a blank second line if the Electronic Brandlining ISM parameter is set to an
Electronic Brandlining ISM default value.
For new systems, the NORTEL_BRAND prompt is automatically set to YES
(default), and the “NORTEL” default brandline is displayed. For the
Terminal Text Broadcast option, the NORTEL_BRAND field is
automatically set to YES (default); although, the NORTEL_BRAND field is
not applicable nor is it output in Overlays 17 and 22. The Terminal Text
Broadcast customized brandline is initially set to the default “NORTEL”
brandline.
