Ring Transfer
of CO Line Allowed,
LED 07-
This
option
defines
station
operation
for
transferring
[DN]
and CO line calls.
If Ring
Transfer
is allowed,
the system
will allow "blind"
transfers
to busy or idle stations.
The transferring
station may release a transferred
call before the
called party answers.
If not allowed,
the system
will allow supervised
transfers
only-the
called
station must answer before the transferring
station
releases.
If Ring
Transfer
is not
allowed,
immediate
recall
occurs
if "blind"
transfer
is
attempted.
The system
denies

LED
06-If
selected,
the incoming
ringing timing pattern at a station will
be the same as the CO line ringing pattern. This is
used mainly with Centrex
or PBX systems
which
may vary the ring pattern
to distinguish
between
internal
and
external
incoming
calls,
etc.
If
Standard
Ringing
is chosen,
CO line station
ringing will be a one second on, three seconds off
cycle regardless
of the incoming
ring pattern.
Some Central Offices have ringing characteristics
such that this option would not be desirable.

amount
of time between
incoming
CO line ring
signals
determines
when
the
system
will
discontinue
(abandon)
sending
ringing tones
to
stations.
The choice
of six or eight seconds
is
dependent
on
the

pattern.
This
assignment
has no affect
if the Line
Repeat
Ringing (LED 06) option is used.

Dual-tone
Multi-frequency
(DTMF) Signal Time,
LED

signals sent out to CO lines can
be either 80 or 160 milliseconds
in length. DTMF

(including voice mail ports) are not affected
by this

This
program
pertains to manual dialing or speed dialing from all
Toshiba telephones,
except when manually dialing

experience
the following
situations:
no dial tone
when a line is released and reseized immediately;
or, when operating
behind Centrex
