On
SUPEf?SET#
DN and
SUPERSET
telephones, the camped
on party identification display takes precedence over the held party
display.
Calls camped on to a device are serviced in two groups, trunks and
internal callers, with trunks being sewed first. Within each group calls
are serviced on a first-come, first-served basis.
When a party camps on to a busy trunk group, the DTMF receiver
used to reach the trunk group is released. The campon to the trunk
group is honored when a trunk group is free and a DTMF receiver is
free.
The Attendant or an extension can transfer a call to a busy destination.
The transferred party camps on immediately.
The transferred party can camp on as long as the transferring party
can camp on. COS checks are done on the transferring party and the
transfer is disallowed if the transferring party cannot camp on.
The transferred party hears system music while camped on; if there is
no system music, silence is heard.
All devices except the console can camp on; consoles and extensions
can transfer a call into campon.
If Campon is allowed for a call, special busy tone is supplied for1 0 sec-
onds, after which the device is camped on automatically.
If campon is not allowed for the call then busy tone is heard for 30 sec-
onds and then the call is disconnected.
DID and CO trunk calls that campon to busy devices receive ringback
tone.
Tie and DISA trunk calls that campon to busy devices receive busy
tone (the same audio as internal callers).
If there is no busy intercept then a DID trunk immediately camps on to
a busy device if the trunk is allowed to campon to the device.
On busy tone timeout, a serial call is dropped, and does not recall.
On SUPERSET 4,
SUPERSET 4
DN, and
SUPERSET 430
telephones
a Campon softkey is provided. On
SUPERSET
telephones a Wait
softkey is provided. On
SUPERSET
DN, and
SUPERSET
tele-
phones, a CAMPON feature key can be programmed to activate
Campon. (See Feature Keys).
If a SUPEI?SETtelephone is using the display or SuperKey feature
while camped on to ARS, the campon is not honored when ARS be-
comes available; it is only honored after the telephone exits from the
feature and ARS is available.
Industry-standard telephones and SUPERSETtelephones that camp
on to a device without using a softkey hear busy tone while camped
on.
