Call Transfer
Description
Call Transfer is used to transfer a CO call or an intercom call from one station to another. When a CO
call is transferred, the outside caller will hear music on hold (if equipped) during a screened transfer. If
the call is transferred via unscreened transfer, the caller may hear either music on hold or ring back tone,
depending on system programming.
Conditions
There are two types of transfer:
1.
Screened Transfer.
2.
Unscreened Transfer.
Programming
Mode 05-02-04, Single Line Telephone Release Time (default setting 5=800 milliseconds) defines the
maximum hook flash interval that is allowable for the system to recognize as a FLASH command. Any
hook flash (open loop) condition that exceeds this time parameter is considered as a disconnect. A hook
flash that does not exceed this time but exceeds the time parameter defined in Mode 05-02-06 is
considered a FLASH. The possible settings are listed in the table below (ms=milliseconds):
Single Line Telephone Release Time (0-9)
0=104 ms
1=208 ms
2=304 ms.
3=400 ms
4=608 ms
5=800 ms
6=1008 ms
7=1200 ms
8-1408 ms
9=1600 ms
Mode 05-02-06, Single Line Telephone Hold Signal (default setting 1=100 ms) determines the minimum
open loop (hook flash) condition that the system will recognize as a FLASH. Any hook flash that does not
exceed this minimum timer will be ignored by the telephone system. Any hook flash that exceeds this
time will be determined to be a FLASH if it does not exceed the timer set on Mode 05-02-04 or will be
determined to be a disconnect if its length exceeds the timer set on Mode 05-02-04. The table of valid
entries is listed below (ms=milliseconds):
Single Line Telephone Hold Signal (0-9)
0=64 ms
