3.05 SCO Button
Description
To support prompt handling of outside calls, a CO
line can be assigned to a DN button on a PITS
telephone.
When this function is assigned, a DN button on a
PITS serves as the Single CO (SCO) button.
SCO button feature provides easy access to the
CO lines for extension users who make and
receive many outside calls.
The PITS telephone user can access a CO line
by simply pressing the SCO button without
dialing the CO line access code, and an incoming
outside call can be directed to the PITS
telephone via dedicated SCO button without
assistance of the Operator.
In addition, the associated status LED provides
busy/idle status and the busy to idle reminder.
SCO button can be used either one-way service
(Incoming Only or Outgoing Only) or two-ways
service (Both-Way).
SCO button can be assigned to a PITS telephone
in conjunction with DIL 1:1 or DIL 1:N feature.
SCO button with DIL 1: 1 feature
When DIL 1: 1 feature is employed, SCO button
can be assigned to the PITS telephone
programmed as the destination of DIL 1: 1
feature.
If SCO button is not assigned on the PITS
telephone, an incoming CO call arrives at a PDN
button on it.
The table below shows the relationship between
the DN button programmed as Single CO and the
