Conditions
1. Calls which can arrive at a UCD group (with
OGM) are:
• Incoming outside calls via DIL(1:1) for which
destination is set as FDN of a UCD group
• Incoming outside calls via DID by dialing
FDN of a UCD group
• Incoming outside calls via DISA by dialing
FDN of a UCD group
• Incoming outside calls transferred by an
attendant console or extension
2. Login and Logout
Members can leave the group temporarily
when they will be away from their desks, to
prevent calls being sent to their extension.
(Logout)
They can return to the group when they are
ready to answer a call. (Login)
Refer to Section 4-D-8.00 "Uniform Call
Distribution (UCD)-Log Out" for more
information on login and logout.
3. Busy status
• When "Do Not Disturb (DND)" or "Call
Forwarding" has been set to the extension.
• When any one of PDN has been used.
(Including using own PDN as an SDN at
another extension)
• When the extension is off-hook.
4. Auto-Logout
When a group member does not answer a call
more than a set time period ("Call Forwarding-
No Answer Time-Out"), the call will be
automatically transferred to another member's
extension.
If "No Answer Time-Out" occurs twice in
succession, the extension is automatically set
to logout status.
This feature is disabled by the dumb
command "UCD Auto Logout Operation
(ULO)".
What if all members are logged-out?
Assuming that a UCD group has three
members and two are already logged out, and
a call rings into the UCD.
If the member that is logged-in does not
answer after two cycles, "Auto-Logout"
happens. Then, the call overflows to the
overflow destination immediately after the
Auto-Logout.
5. Overflow destination
One of the following three destinations can be
assigned as the overflow destination (OFDN)
per UCD group (01-04).
• Attendant Console
• Extension
• Another UCD Group (01-04), (05-32)
(Treatment of the calls transferred to the overflow
destination (OFDN))
(1) What if the overflow destination is busy?
The call is put in the waiting queue, and will
begin to ring at the overflow destination as
soon as it becomes idle.
The call is put in
the waiting queue.
The call begins to
ring at a group
member's extension.
The call may begin to ring at a group
member's extension, if it becomes idle while
overflow destination is still busy.
