2.08 Single CO (SCO)
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).

The following table shows the behavior of the DN
button programmed as Single CO and the CO
