Emergency Location Database

The MX-ONE Service Node contains an Emergency Location database, which is used to store the data used by the emergency service solution in the MX-ONE.

The data is required as an input and is required by the NG911 service provider to identify a device in MX-ONE side. The data is sent by MX-ONE via SIP trunk headers to Intrado.

The emergency location has the data structure shown in the following table.

Table	Description	Additional information
Location ID (LocationId) Table	Contains information such as Customer ID, Callback Number, and general information.	The Location ID is a reference or identification used to identify a device in MX-ONE. This reference is then sent as an alternative ID instead of an ELIN/CESID in case a full DID number cannot be sent to the NG911 service provider. For example, in a hotel or for enterprise customers where extensions do not have a dialable number. The Customer ID is required by the NG911 service providers to identify the customer associated with that call. The callback number is required by the NG911 service providers if a full DID number (a 10-digit dialable number) is not sent. For example, in a hotel or for enterprise customers where extensions do not have a dialable number.
BSSID Table	Contains information that associates Location ID with BSSID (Access Point Information for Wi-Fi phones) or MAC addresses (SIP Phone) information.	The BSSID is required to identify which Wi-Fi access point, a wireless device, is connected when an emergency call is made. The BSSID is associated with a Location ID. The MAC address is optionally used to identify which SIP Phone was used to make an emergency call. The MAC address is associated with a Location ID. It is mainly used in Teleworker mode. It can also be used in conference rooms and corridor phones.
DIR Table	Contains information that associates Location ID with a Directory Number (extension).	It can be used for fixed devices and in some specific cases with non-fixed devices, such as H.323 phones, third-party SIP phones or ATA (Analog Terminal Adapters).
LIM Table	Contains information that associates Location ID with a specific Service Node (LIM) or all Service Nodes (LIM).	The LIM table can be used in some customer scenarios, where many devices (SIP, IP, analog, and digital phones) reside in the same physical location (or same building floor).
Customer Group Table	Contains information that associates MX-ONE customer groups (multi-tenant/CUST) with NG911 service provider Customer ID.	It is used to associate an MX-ONE customer group (CUST) with the NG 911 Customer ID. It can also contain a callback number to be used by the MX-ONE customer setup. Customer group 0 is the default and all extensions will be assigned to this group if no other customer group is specified. One entry can be specified by each customer group used by the systems (including customer group 0). Note: Using the customer group setup simplifies the MX-ONE configuration, because it does not require that the Customer ID parameter is configured for each entry in the Location ID table. Note: If Customer ID is defined in both the Location ID table and the customer group table, the customer ID in the Location ID table has higher priority.

To define Emergency Location, the following setup is required:

The Customer ID required by Intrado to unique identify a customer. The E911-Organization-ID is the SIP header used to transport the Customer ID to Intrado.
Note: It is mainly used when sub-accounts are defined in Intrado portal and customer groups are defined in MX-ONE.
The Location ID required by Intrado in case of a full DID number is not sent. The "FROM" is the SIP header used to transport the Location ID or an ELIN/CESID to Intrado.
The Callback Number required by Intrado in case of a full DID (10-digit dialable number) number is not sent. The P-Asserted-Identity "PAI" is the SIP header used to transport the callback number to Intrado.
The BSSID required to identify in which access point, a Wi-Fi device is connected when an emergency call is made. The BSSID is associated with a Location ID in the MX-ONE emergency location database, and then the Location ID is sent to Intrado. The "FROM" is the SIP header used to transport the Location ID to Intrado.
The MAC address required to identify which SIP Phone was used to make an emergency call. The MAC address is associated with a Location ID in the MX-ONE emergency location database and then the Location ID is sent to Intrado. The "FROM" is the SIP header used to transport the Location ID to Intrado.
The Directory number (DIR) associated with a Location ID in the MX-ONE emergency location database and then the Location ID is sent to Intrado. The "FROM" is the SIP header used to transport the Location ID to Intrado. It can be used for fixed devices and in some cases with non-fixed devices, such as H.323 phones, third-party SIP phones or ATA (Analog Terminal Adapters).
