Title: SOSE CS 1000 Release 5'0 ESAESCM Review
1(No Transcript)
2Quick Update on release 3.0
- Release 3.0 Software was introduced on October
27, 2003 and Order Deadline for R3 - ExpansionsThe last date to have clean orders
into Nortel for expansion of existing Release 3
systems is June 16, 2008. Expansions after that
date will require an upgrade to current release. - Upgrading to CurrentThe least expensive way to
upgrade is to use SRS to upgrade a Release 3
system to Release 5 (or 5.5 planned for March
28th). Even though Release 3 will be Retired in
July, you will still be able to purchase SRS to
upgrade to R5 or R5.5 until R6 becomes available
next year (currently planned for 1Q09). - Support of Retired SoftwareLimited Nortel
Enterprise Technical Support (NETS/GNTS) support
is available once a software release is Retired.
Currently the policy is that no new PEP's
(patches) would be created to solve a customers
problem however a PEP will be provided if one
already exists.

- PLEASE NOTE 911 LAWS AND REGULTIONS GREATLY VARY
BY GEOGRAPHIC LOCATION - ALL LOCAL LEGISLATION AND CAPABILITIES MUST BE
CLEARLY UNDERSTOOD AS PART OF SETTING UP CUSTOMER
911 SOLUTIONS
6Why the increased awareness?
Situations such as the one above are becoming
more frequent Recent occurrences at various
Universities and schoolsIP telephony and
mobility
7Facts about the incident
- Known Facts about the Incident
- Company has 15 different locations working from 1
PBX. Location information for all these buildings
was the address associated with the companys
billing address. - Fatality occurred because the emergency crew
arrived at this listed address determined from
the CLID the employee was in an adjacent
MedImmune building with a different street . - Companies IP-PBX was a well known PBX Vendor with
VoIP deployed however there was no E911
Emergency Responder - Source familiar with the Company network revealed
there were no local trunks at each location that
would have enabled site location. - UnKnown Facts about the incident
- Company, a multinational company with 2200
employees and 7 U.S. locations Did they have an
emergency policy? Would notification to local
security have helped? The employee died on 9 am
on Tuesday and not during off hours. - Does the distributor or installation prime bear
any liability for failing to provide sufficient
information on 911 practices or recommendations?
8What is the Law?Laws Vary by Country, State,
Province
- The CRTC regulations state only the billing
address of the PSTN Service must be sent to the
Emergency Response Center and that a callback
must be answered - Today this policy is consistent across Canada
- Some carriers provide a chargeable service
whereby PBX DID numbers can be used to identify
more specific locations within a location. - This service may not be available in all regions
- Carrier manually enters these numbers in the 911
database and uses the modified record to send
the refined location
9Lets start with simple Caller ID
- When a call is presented to your home phone, your
local Central Office looks up the calling number,
and adds name information.

10PBX Systems and CLID
- PBX system software sends the CLID via a PRI
based on programming. It is not assigned
automatically by the Central Office. It can be
changed, or spoofed by the originating PBX.

11What is E911 and how does it work
- In its most simplistic definition, E911 is
nothing more than a Call Center Screen Pop
application, based on the ANI (caller ID) of the
caller.

14CLID and ANI There IS a Difference
- LECs may treat the CLID differently when a call
is made to 911. Depending upon the functionality
available in the Class 5 switch, the CLID may not
be used as the ANI for 911 call routing. Instead,
the network may be programmed to use the listed
directory number (LDN) or the bill-to number
(BTN) for ANI purposes. - If the CLID is not used for ANI, then 911 calls
coming from a PRI interface all look the same to
the 911 network because they all have the same
ANI. - Many LECs offer CLID transparency through a PRI
interface for 911 calls. With this feature, the
CLID presented is used as ANI to route the call.
15The E911 Selective Router
- Selective Routers provide routing from the
Emergency Caller to the PSAP servicing their
physical address. - These are usually dedicated Telco based Tandem
COs, however the Selective Router could be
virtual using a database dip to provide the
proper endpoint PSAP termination. - It is important to understand the Selective
Router topology in the customers service area
before attempting to design an E911 routing plan
for them.

18CS1000/Meridian E911 capabilities
- Today Many systems in Canada utilize a basic form
of access to the PSTN for 911 calling. - The use of an SPN allows users dialing 911 or
9911 to reach a trunk route and send 911 to the
Central Office - This method has been used to adhere to the
Canadian and other regions basic 911 laws - This method does not allow for the use of
Emergency Services Access that was introduced
many years ago to enhance E911 capabilities and
meet more stringent regional regulations
19Nortels ESA Software
- Handles the proper calling numberpresentation to
the PSAP - Provides ESA CLID services to locations by
- Identifying E911 calls
- Provides proper call handling and priority
routing - Supports Multiple NXX Exchanges
- Supports Non-DID telephones
- Support for Tandem 911 calls in a campus
environment - Supports Multiple appearance numbers
- On site notification to OSN Telephone
- On site notification to TTY device
- ESA Audit Capabilities WITHOUT Calling 911
20Emergency Service Directory Number (ESDN)
- ESDN is a number assigned within a
CS1000/Meridian that when dialed alerts the
system that a call requires emergency treatment.
- If an ESDN is defined as 911 an SPN can be
defined as 9911 which is re-ranslated to 911 to
receive ESA treatments (this is shown later) - Allows Primary ESDN up to 15 additional ESDNs
- Independent routing per ESDN in ESA Data Block
- Required for EMEA or international enterprises,
i.e. - North America 911
- Mexico 060, 066, 080
- UK 999, 112
- Europe 112, 118, 117, 144, 145, 140, 143, 147,
1414 - Asia 108, 119, 999
- Internal ESDNs
- i.e. 2222 for internal hospital emergencies
calls can locally terminate in the customer
network based on the originators location (i.e.
per floor)
21Location Values
- In CS 1000, release 5.0, the location of an
telephony client is represented as - ERL (Emergency Response Location) - a 16 bit
value indicating the ERL in which the client is
currently located. - A value of 0 indicates that the ERL is unknown.
- ERL values must be unique network wide.
- ECL (Emergency Caller Location) - a 16 bit value
indicating a more granular location that may be
described in the PS-ALI record for an individual
telephone DID number. - For example it may be a unique number indicating
the nearest pillar or an individual office or
cubicle. - ECL values may be defined at the same granularity
as an ERL, as long as the PS-ALI records are
configured at the same granularity. - ECL locations must fall within the boundary of an
ERL. - ECL values are unique network wide and may NOT be
re-used within a different ERL. - A value of 0 indicates that the ECL is unknown.
- Location Description a 20 character string
indicating the location of the IP client. - The description may be configured to correspond
to the 20 character free form location field
contained in the PS-ALI record used to identify
the location of a caller within a building. - The string may contain any characters except
quotation marks () and colons (). - The location description is not mandatory,
however it can provide useful information for On
Site Notification reports, location reports and
other functions.
22Emergency Response LocationsContinued
- ERLs apply to every station TN in the system,
including non-IP phones TDM stations all
maintain static location data - If the ERL is not configured, or the ERL0, the
call server uses the default ESA Data Block
parameters that were defined and available prior
to Emergency Service Client Mobility) ESCM and
Release 5.0 - In addition to telling the call server to fall
back to ESA Data Block parameters, ERL 0
indicates an Unknown location for IP stations.
23Dynamic ELIN
- ELINs (Emergency Location Identification Number)
can be automatically assigned to an emergency
caller based on the ERL in which they are
located. - ELINs are assigned whenever the DID number of a
phone either doesnt exist or it is not usable
based on the location of the caller or if not
maintained in a PS-ALI database. - Static ELINs represent a fixed phone in the area
of the caller(within the ERL) - Dynamic ELINs do not have a permanently assigned
physical phone - They are dynamically assigned to an emergency
caller and forwarded to the call originator to
facilitate call back from the PSAP. - Dynamic ELIN overflow/re-use
- Can be configured to re-use the oldest dynamic
ELIN or overflow to the static ELIN. - Callback fallbacks
- Dynamic ELINs use phantom or virtual TNs and can
be configured to route calls appropriately in the
event the originating phone is not available. - Default Call Forward, Flexible Call Forward no
Answer
24Automatic Switching between Personal DID and ELIN
- Each IP phone is configured with a home ECL
value if it has a DID with corresponding entry
in the PS-ALI database. - The home ECL value represents the location that
is described in the PS-ALI record for the DID
number associated with the phone. - If the current ECL value reported by the location
service is the same as the configured home ECL,
the DID, as configured in the ESA portion of the
associated CLID block, is used for signaling
location to the PSAP. - If the values do not match, then an ELIN is
selected based on the current ERL of the phone. - This enables the conveyance of location at a
station level to the PSAP for phones that are at
their normal (configured) location. - Automatic ALI updating (3rd party) can be used to
automate the move/add/change process by updating
the PS-ALI database.

26Location Discovery MechanismsAllows Dynamic
Updates as IP Movement Occurs
- In Release 5.0 two mechanisms are available for
Location Discovery with ESCM - I-LIS
- An internal subnet lookup mechanism that will map
specific IP address ranges to a specific ERL - Package enabled in EC less than 10,000 US
- E-LIS
- An external interface available to any 3rd party
Discovery Manager - Provides a simple way to collect information
about registered sets - List of all sets currently registered
- List of sets requiring a location update
- Mechanism to update the Call Server for any IP
set that was discovered - The E-LIS interface is provided with the base
software package - Several 3rd party Development Partners are
working on Release 5.0 Compatibility
Certifications - E-LIS interface no longer ties up the Overlay
space as was in the case in Release 4.5
27Internal Location Information Service (LIS)
- Assumes network architecture lines up with
enterprise geography (i.e. floors within a
building) - Relies on DHCP server assigning IP addresses by
subnet, i.e. by location - Looks up phones IP address in subnet table and
assigns location data associated to subnet entry - Implemented on Call Server
- Handles re-location of desktop phones, Virtual
Office, etc.

- Enabled Recognition of potentially misdialed
Emergency Calls - This functionality MUST be explicitly enabled
- A warning message is displayed prior to
activation of this feature. - Additional digits dialed following ESDN within
wait period cause call intercept. - Wait period configurable from 1 To 4 Seconds
(default 2 seconds) - Wait period will delay origination of emergency
call. - will terminate wait period and process call
immediately - A repeating final digit can optionally be allowed
without intercept - E.g. 9-1-1-1-1 or 1-1-2-2 would not be
intercepted if enabled. - Intercepted Call Treatment can be configured
- OVERFLOW, BUSY, ATTENDANT, RAN ROUTE xxx
- On Site Notification
- Call Intercept log generated.
- Call Intercept SNMP Trap generated.
- OSN set alerted as per normal ESA call.
- Local responders must immediately investigate ALL
intercepted emergency calls to ensure that an
actual emergency did not occur.
35ESA CLID Audit
ClID Audit was introduced in release 4.0 and s a
useful tool for Validating CLID for all types of
calls. With E911 it allows Verification before

When VO Logged Out
- The E911 Virtual Office Logged Out (VOLO) feature
will allow the Virtual Office Logged Out Set to
make an emergency call. The feature will work on
all the phones which support the Network Wide
Virtual Office. - The feature depends upon the ESA feature to route
the call. Non-ESA call will result in a overflow.
- No other feature such as transfer, conference,
redial, mail box, directory etc. are provided to
this set - IP Phones CANNOT register to VOLO TN Type
- This feature is to allow VO Logged out sets to
make an ESA call without having to login. - Up to 255 VOLO TNs can be configured
- Must be contiguous in the system
- DO NOT use IP Licenses
