CPC Calling party control,also known as line supervision or wink disconnect signal-
ling. All of these termsrefer to the brief interruption in the battery current on an
analog line, to indicate to connected equipment whe n a distant party has discon-
nected. The CPC signal is required by the Nex Path TelephonySer ver on
inbound CO lines, to prevent calls thatare in the auto-attendant or conferenced
with other CO lines, from becoming connect ed indefinitely even though the out-
side party has hung up. Most if no t all central offices in the US provide this sig-
nal, but some channelbanks (analog line conversion from T1 digital lines) do
not. NexPath does not recommend connecting the NexPath Telephony Server to
channel bank or ISDN-to-analog equipment that does not provide the CPC sig-
nal.
CPC Delay The CPC delay is the time fromwhen the caller actually has disconnected, to
when the central office sends the CPC signal. The NexPath Telephony Server
has a programmableCPC delay compensation adjustment, to compensate for this
time delay,to eliminate long periods of silence at the end of voice mail messages.
This can be programmed by the system administrator. See the System Adminis-
tration Guide for details. The CPC delay compensation is merely a fixed amoun t
of time that is chopped off of the end of all voice mail messages. If y ouf ind
voice mail messagescut off at the end, the CPC delay compensation factormay
have been set too large. Contact your system administrator.
Day mode Each extensioncan be assigned to ring at a different phone or group of phones
depending on whetherthe system is in the Day mode or Night Mode. Usually,
systems are configured so that calls placed to the operator ring at the opera tor’s
phone when the system is in Day mode, but ring over the overhead PA speaker
when the system is in Night Mode. Individual extens ions may be similarly con-
figured. Day and night mode can be changed from the telephone keypad and
from the web application Te lO per , as described in the Users Manual.
Do Not Disturb mode Individual extensions can be placed in either an “Accept Calls” mode o ra “Do
Not Disturb” mode. When an extensionis in “Do Not Disturb” mode, calls
placed to it will not ring the phone but instead will be sent directly to voice mail.
If the extension is part of a call distributiong roup,incoming calls will be routed
past any extensions which are in the “Do Not Disturb” mode and wi ll go on to
the next extension in the group.
