This feature brings the system into compliance with the Federal
Communications Commission (FCC) decision that requires a circuit
switched network, working as a Public Safety Answering Point (PSAP),
to accept a 10 or 20 digit Automatic Number Identification (ANI) when
terminating 911 calls.
79
10 digit ANI feature
The 10 digit ANI feature addresses the increasing number of Numbering
Plan Areas (NPAs) in North America. The increasing number of NPAs
requires that a single PSAP must be capable of handling multiple NPAs
within its jurisdiction.
The 10/20 Digit ANI on 911 Calls feature changes the ANI format to include
the NPA in the ANI field. A single PSAP can handle any number of valid
NPAs with the 10 digit format.
20 digit ANI feature
The 20 digit ANI feature addresses the problem of accurately determining
the location of a wireless calling party dialing 911.
The first 10 ANI digits provide the Calling Station Number (CSN). The CSN
for a 911 call is the Calling Party Number (CPN), if available, or the billing
number if the CPN is not available. The CPN, if available, is used to call the
originator back when a 911 call is disconnected.
The second 10 ANI digits, or Pseudo Automatic Number Identification
(PANI), provides the cell site and sector information to best define the
wireless calling party’s location. The PANI allows emergency assistance to
be sent to the correct area.
II digit definition
The 10/20 Digit ANI feature replaces the NPD with two II digits. The
definition of II digits is as follows:
•
40 for normal display
•
44 for flashing display (Default Routing)
•
48 for a test call
Note: The system uses an attached "*" instead of a "flashing display".
Default Routing is used when the Selective Routing process at the
Central Office does not produce a valid Emergency Service Number
(ESN). If no valid CSN information is available on a wireline call, or if
no valid cell site and sector information is available on a wireless call,
the call is sent to the default ESN associated with the incoming trunk
group for that call.
CSN wireline calls format
The CSN wireline call format is as follows:
KP II NPA NXX YYYY STP
Where:
•KP is the key pulse.
•
NPA NXX YYYY represents the originator’s CSN.
•
STP is a digit that tells the system that there is only 10 digits. Termination
of the call occurs immediately after receiving the STP digit.
CSN wireless calls format
The CSN wireless call format is as follows:
KP II NPA NXX YYYY ST KP X...X ST
Where:
The first ST digit flags the call register as a wireless call for display
purposes.
•
The second KP marks the beginning of the PANI.
•
X...X represents the cell site and sector identification. Although 10 digits
are required for this information to be complete, any availableinformation
is sent. Therefore, this information can range from 0 to 10 digits.
•
The second ST digit terminates the call.
Digit Display
Wireline
Wireline M911 calls display on a digital telephone as follows:
•
For calls with II digits equal to 40, the 10 digits display as:
— NPA NXX YYYY
•
For calls with II digits equal to 44, the 10 digits display as:
— NPA NXX YYYY*
Feature description81
Wireless
Wireless M911 calls display on a digital telephone as follows:
•
For calls with II digits equal to 40, the 20 digits display as:
-
(PANI)NPA NXXX YYYY WIRELESS
-
(CSN)NPA NXX YYYY
•
For calls with II digits equal to 44, the 20 digits display as:
-
(PANI)NPA NXXX YYYY WIRELESS
-
(CSN)NPA NXX YYYY*
911E (end-office) call processing
With the 10/20 digit ANI for 911 Calls feature, the system continues to
expect the dialed digit(s) first.
The dialed digit format is KP+digits+ST, where the digit(s) are 911, 11, or 1,
followed by the ANI CSN information.
With the 10/20 digit ANI for 911 Calls feature, the system does not expect
the dialed digit(s) (911, 11, or 1), only the ANI CSN information.
Operating parameters
This feature is compatible with the system.
The functionality of the 10/20 Digit ANI on 911 Calls feature depends on the
local telephone company to comply with Bellcore GR-2953. Therefore, the
ability to collect the 10/20 digit ANI formats must be enabled on a separate
trunk route basis.
If the 20 digit wireless calls are tandem to the ISDN route, the display shows
the II + 10 digit CSN.
The Custom Local Area Signaling Service (CLASS) telephone only displays
up to 10 digit ANI.
Feature interactions
Call Trace
Call Trace in LD 80 is modified to show II NPID + 10 digit ANI information.
The Call Trace record also shows the PANI information.
Call Detail Recording
The Call Detail Recording record (with package 234) is modified to display
PANI for wireless calls when FCDR = NEW in LD 17.
Display on CLASS telephones
Only 10 digit ANI will display on a CLASS telephone for both 911E or 911T
trunk. The PANI will not display. However, if it is a wireless call, the PANI
can be traced by LD 80.
Display on tandem call
Only II + 10 digit ANI will display on the telephone when M911 calls are
forwarded or transferred through ISDN or PRA routes. This only applies
for 911E route types.
Malicious Call Trace
The Malicious Call Trace record is modified to show II NPID + 10 digit ANI
information. The record also contains the PANI information.
Feature packaging
M911 Enhancement Display (M911 ENH) package 249 is introduced with
this feature.
This feature allows the use of a 2500-type telephone with 16 buttons instead
of 12 buttons. The extra keys provide single button access to features that
would otherwise require the use of Flexible Feature Codes. The feature also
provides an autodial function. With this feature, autodial is also available
to 12-button Digitone/Multifrequency (DTMF) telephones equipped with a
true ground (GRD) button and 2500-type telephones with switchhook flash
and calibrated flash.
Not all telephones must share the same assignments. In LD 18, functions
can be overlay programmed against a key for each of the three modes. A
set of these key-function definitions can then be assigned to one or more
telephone station groups. Up to 127 sets of key function assignments
(called ABCD tables) are permitted.
The following Flexible Feature Code functions can be accessed using
the new (A, B, C, D, * and #) keys while in the pre-dial mode (when the
telephone is receiving dial tone):
The following functions can be accessed using the new (A, B, C, D, * and #)
keys while in the post-dial mode (when it receives special dial tone after a
recall during an active call, or after a busy DN has been dialed):
•

Feature operation
Each button (A, B, C, D, * and #) can have up to three functions assigned to
it. The function accessed when a key is pressed is determined by the mode
of operation (pre-dial, post-dial or control mode). Functions are assigned
to keys by way of overlay programs. The functions can be either Flexible
Feature Code functions or the autodial function. An autodial number (of up
to 23 digits) can be assigned to any of these buttons for either the pre-dial
or post-dial modes. In addition, an autodial number can be assigned to the
recall (RCAL) button in the pre-dial mode.
The 2 Mbps Digital Trunk Interface (DTI2) feature provides digital
connectivity between a system digital network loop and an external digital
carrier termination. It provides digital speech on up to 30 channels at 2
Mbps on one system loop and the bipolar carrier terminal. Within the
system, the DTI2 operates as a general purpose sender and receiver of
ABCD (signaling) bits. The DTI software sets the ABCD bits to represent
the appropriate signaling for the trunk being supported.
For 2 Mbps DTI, use the QPC775 clock controller.
Operating parameters
There are no operating parameters associated with this feature.
The following enhancements have been added to the existing 2 Mbps Digital
Trunk Interface (DTI2) in order to meet various customer requirements.
Alarm Handling on Direct Inward Dialing Channels
If an alarm condition occurs on a Direct Inward Dialing (DID) channel, this
enhancement delays the sending of connect and disconnect signals, until
the alarm condition is cleared.
Alarm Handling on Incoming Public Exchange/Central Office
or Direct Inward Dialing Trunks
This enhancement clears non-established calls on incoming Public
Exchange/Central Office (CO) or Direct Inward Dialing (DID) trunks when
an alarm condition occurs. When the alarm condition is cleared, the calls
are diverted to the attendant.
This enhancement affects the handling of incoming and outgoing call
clearance for Central Office (CO) calls.
Call Clearance is handled differently if the Clear Forward signal (CLRF) is
defined, or if the Clear Forward signal and the IDLE signal do not have the
same definition. The Call Clearance is also handled differently for outgoing
and incoming calls.
For outgoing calls being disconnected by the system, a clear forward and
then an IDLE signal is sent by the system. The call state determines when
the IDLE signal is sent. If the call is answered, the IDLE signal is sent within
300 milliseconds of the reception of a clear back signal from the CO. If the
outgoing call is not answered, the IDLE signal is sent after 800 milliseconds
(plus or minus 50 milliseconds) of the clear forward signal being sent. If the
CO answers during this 800 milliseconds period, the system continues to
send the clear forward signal until it receives a clear back signal from the CO.
For outgoing calls being disconnected by the CO, a clear back signal is sent
by the CO when it wishes to disconnect. The system then sends a clear
forward signal within 300 milliseconds of having received the clear back
signal, followed by an IDLE signal within 800 milliseconds (plus or minus 50
milliseconds) of having sent the clear forward signal.
For incoming calls being disconnected by the system, a clear back signal is
sent by the system. Upon receiving a clear forward signal from the CO, the
system sends an IDLE signal within 300 milliseconds of having received the
clear forward signal.
For incoming calls being disconnected by the CO, a clear forward signal is
sent by the CO when it wishes to disconnect. If the call is answered, the
system sends a clear back signal within 300 milliseconds of having received
the clear back signal from the CO, and then an IDLE signal after 800
milliseconds (plus or minus 50 milliseconds) of having sent the clear forward
signal. If the call is not answered, the system sends an IDLE signal within
300 milliseconds of having received the clear forward signal from the CO.
If an alarm condition occurs while a clear forward or clear back signal is
being sent for the 800 milliseconds time period, the system continues to
send the signal until the alarm condition clears.
Clock Synchronization
This enhancement affects the clock synchronization controller. If a DTI loop
enters its most severe alarm state (the No-New-Calls state), the system
disables the clock port.
The Central Office (CO) operator will be able to offer a Direct Inward Dialing
(DID) call to the attendant. When a DID call terminates on a busy station,
and the End of Selection Busy (EOSB) signal has been sent to the CO by
the analog (500/2500 type) telephone, the CO can then send an Operator
Pulse Signal (OPRS) back to the analog (500/2500 type) telephone. This
OPRS causes the analog (500/2500 type) telephone to forward the call
on to the attendant.
Disable Out-of-Service Alarm State
This enhancement allows the system to disable the Out-of-Service (OOS)
alarm state for an error, leaving the No New Call alarm state as the most
severe state. This is done by setting the OOS threshold time for an error
to zero.
Fault Signal
On an incoming call, if a Fault (FALT) Signal is received by the circuit
switched network while in an IDLE state, the circuit switched network will
respond with a Fault Signal until the CO returns to the IDLE state. On an
outgoing call, the circuit switched network will enter the FALT state if a
Release Control (RCTL) signal is not received within 30 seconds.
Feature description99
Incoming Seizure
This enhancement, applied on a group basis, allows the Central Office to
initiate a call from a lockout or far-end fault state.
Outpulsing Delay
This enhancement provides a delay before outpulsing on 2 Mbps DTI trunks.
Release Control
The circuit switched network will now be able to send and receive the
Release Control (RCTL) signal, which is sent by the called party on both
incoming and outgoing calls to indicate disconnection is complete. The
RCTL signal is sent by either the CO or circuit switchednetwork in response
to a Release Clear Forward signal.
Signal Recognition
This enhancement gives the system more flexibility in handling receive
signals. The system can recognize a signal based on the ABCD signaling
bits. Any non-significant signaling bits of a receive signal can be flagged
as do-not-care. The system can then ignore these do-not-care bits before
trying to determine which signal it has received.
This enhancement adds the 64 Kbit Alarm Indication Signal (AIS) as a
sixth group II error state. This error state is treated the same as the other
group II error states.
Centre National des Études des Télécommunications
enhancement for trunks entering an alarm state
This enhancement requires the QPC915 and ensures compliance with the
Centre National des Études des Télécommunications (CNET) requirements
for trunks entering an alarm state.
Trunks entering an alarm state are processed according to the type of trunk
they are configured as and their previous state.
Forall cases, signaling will not occur on the trunk while it is in an alarm state.
Idle trunk
When an idle trunk enters an alarm state, it will not send the "FAULT" signal.
DID trunk
Trunk seized and receiving digitsThe call is taken down and the trunk
is idled.
Call initiated but not answeredA timer is started when the alarm state
is entered, its duration is between 20 and 40 seconds, and the called
telephone continues to ring. During this time one of three cases may occur:
•
The timer expires: the call is disconnected, all resources but the
incoming trunk are released (delayed disconnect). This occurs even if
the following case has already happened.
•
The called telephone answers: no affect on the timer; the delayed
disconnect will occur if the alarm is not cleared.
•
The alarm stops: no affect on the connection, the timer is stopped and
reset, and delayed signals are sent to the far end.
Call answeredThe call is not dropped upon entering an alarm state. If
the near-end party goes on-hook during alarm, the party is released and all
resources are idled except the trunk, which is put in a delayed disconnect
state.
DisconnectThe alarm is ignored with respect to internal system
processing, and the trunk is put in a delayed disconnect state.
