In a PBX system, what component provides the location of the caller to the 911 call taker?

In a PBX (Private Branch Exchange) system, the component responsible for providing the location of the caller to the 911 call taker is known as the pS/ali, which stands for the Private Switch Automatic Location Identification. This system is crucial for emergency services, as it transmits the specific location of a caller who is using a PBX phone system, ensuring that emergency responders can quickly and accurately find the caller in a timely manner.

When a call is made to 911 from a PBX system, the pS/ali captures the caller's information, including the address associated with that specific extension. This contrasts with other components in the system. The master database may contain extensive information about the PBX setup and user configurations, and the call log records details about calls made within the system, but neither of these functions directly relates to providing real-time caller location for emergency services.

The location identifier is a broader term and does not specifically refer to the technology utilized in PBX systems for handling emergency calls. Therefore, the pS/ali is the specialized system that ensures emergency operators receive the precise location necessary for response.
