Task Force 34 – Focus on ESIF
Issue 34
• Task Force 34 is responsible for
deliverables associated with ESIF
Issue 34 – thus the name “Task Force 34”
• Initial ESIF Issue 34 acceptance at ESIF
10 (July 2004)
• Updated Issue 34 acceptance at ESIF 12
(Jan 2005)

American National Standards Focus
Issue 34 Deliverables
• ATIS/ESIF – ANSI Accredited for the production of
American National Standards (ANS)
• Foundation: Openness, Transparency, Due
Process – Per ATIS Operating Procedures –
based on ANSI Essential Requirements;
recognized for diligence; combined with rapid
execution.
• Implementation of ANS are voluntary unless
mandated
• Announcements/Liaison for Coordination: Wide
announcement of work; utilizes ESIF/NENA
leadership liaisons

Issue 34 – Overview
Drivers
Driver: next generation emergency services data
messaging needs:
– NENA Technical Information Document on Future 9-1-1
Models (Future: Based upon standard IP protocols, utilizing XML
in a more robust protocol than envisioned by the ALI Bid/ Response
model, including support of extensions for supplemental information
delivery).
– PSAP ALI Interface - Next Generation Needs (see TF34
contributions: ESMI-010, ESMI-011)
– Need for Web Services based interface in support of
emergency information services
– APCO guidance regarding diversity of PSAP needs
6
Issue 34 – Overview
Initial Focus (July 2004)
Initial Focus: Emergency Services
Messaging Interface (ESMI)
– Interface for Logical Entities/Agents:
Response Gateway (RG) to Conforming
Emergency Services Entity (CESE):
• ESNet (for messaging) to PSAP CPE Interface
• Provides for well defined TCP/IP persistent
connection interface framework for PSAP CPE
(next generation emergency services messaging)
• XML Schemas to be referenced
7
Issue 34 – Overview
Current Focus (Updated Jan 2005)
Current Focus: ESMI; and Emergency
Information Services Interface (EISI)
– Interface for Logical Entities/Agents:
Response Gateway (RG) to Entities Providing
Emergency Services (EPES) for EISI:
• ESNet (for messaging) to EPES
• Provides for well defined Web Services based
service interface framework for emergency
information services (e.g., telematics providers)
for next generation emergency services messaging
• XML Schemas to be referenced or discovered

(e.g., a PSAP can
contain ESNet and
provide all three
interfaces).

ALI becomes a special case of a “Service”.
Communication to the PSAP is generalized.

Relationship to NENA i2 and i3
• Relationship to NENA i2:
– ESMI, EISI and ENEN can be used for basic ALI
and/or advanced emergency information delivery
– Use of various architectural configurations – driven by
PSAP needs
• Relationship to NENA i3:
– ESMI, EISI and ENEN can be used for advanced
emergency information delivery
– Use of various architectural configurations – driven by
PSAP needs

Issue 34 – Status*
Feb 20, 2006
• Emergency Services Messaging Interface (ESMI):
– Trial Use Standard completed Sept 2005
– Pre-Publication version of ESMI Standard available:
ATIS-PP-0500002-200X: Emergency Services Messaging Interface
• Emergency Information Services Interface (EISI): Stage 1
(Requirements) and Stage 2 (Analysis) are completed; Stage 3
(Detailed Interface Specification) started during ESIF 13. Standards
Development is continuing.
– EISI Plan: Targeted for completion in July 2006 (with initial Letter Ballot
issuance in May 2006)
• ESNet to ESNet Interface (ENEN): Work not started; no target date set.
Will probably be defined as an extension of EISI.
• See Task Force 34 posted meeting notes for more detail; TF34 Web

Conclusion
• Task Force 34 focus is on next generation
emergency services data messaging
• Driven by common understanding of next
generation emergency services messaging needs
• Three interfaces: ESMI, EISI, and ENEN targeted
as American National Standards (ANS)
• Flexible configurations for interested parties –
e.g., to meet the needs of various PSAPs
• Interfaces play well with foreseen future
directions of next generation emergency services
