26.11.4.2.2 Adding ELINs to the Location Information Server
As mentioned in the previous section, the Administrator needs to populate the Location
Information Server (LIS) database with a network wire map, which maps the Enterprise's
network elements to civic addresses. Once done, it can automatically locate clients within
a network. You can add addresses individually to the LIS or in a batch using a comma-
separated value (CSV) file containing the column formats listed in the table below.
Network Element
Wireless access point
Subnet
Port
Switch
For the ELIN number to be included in the SIP INVITE (XML-based PIDF-LO message)
sent by the Mediation Server to the ELIN Gateway, the Administrator must add the ELIN
number to the <CompanyName> column (shown in the table above in bold typeface). As
the ELIN Gateway supports up to five ELINs per PIDF-LO, the <CompanyName> column
can be populated with up to this number of ELINs, each separated by a semicolon. The
digits of each ELIN can be separated by hyphens (xxx-xxx-xxx) or they can be adjacent
(xxxxxxxxx).
When the ELIN Gateway receives the SIP INVITE, it extracts the ELINs from the NAM field
in the PIDF-LO (e.g., <ca:NAM>1111-222-333; 1234567890 </ca:NAM>), which
corresponds to the <CompanyName> column of the LIS.
If you do not populate the location database, and the Lync Server 2010 location policy,
Location Required is set to Yes or Disclaimer, the user will be prompted to enter a location
manually.
26.11.4.2.3 Passing Location Information to the PSTN Emergency Provider
When a Lync 2010 client, enabled for E9-1-1 emergency services, dials 9-1-1, the location
data and callback information stored on the client is sent with the call through the Mediation
Server to a PSTN-based Emergency Services provider. The Emergency Services provider
then routes the call to the nearest and most appropriate PSAP based on the location
information contained within the call.
Lync Server 2010 passes the location information of the Lync 2010 client in an IETF-
standard format - Presence Information Data Format - Location Object (PIDF-LO)–in a SIP
INVITE message. However, this content cannot be sent on the PSTN network using ISDN
PRI due to protocol limitations. To overcome this, Enterprises using PSTN Gateways can
divide their office space into Emergency Response Locations (ERLs) and assign a
dedicated Emergency Location Identification Number (ELIN) to each ERL (or zone). When
Lync Server 2010 sends a SIP INVITE message with the PIDF-LO to the PSTN Gateway, it
