Navigating the complexities of telecommunications data can be challenging, especially when you need precise information about local calling areas. Whether you’re developing a telecom application, managing communication networks, or simply require detailed data for analysis, accessing reliable and structured information is crucial. This guide introduces you to a powerful XML query interface designed to provide comprehensive data related to local calling, empowering you with the tools you need for efficient data retrieval and integration.
This XML interface offers a programmatic way to access a wealth of information, going beyond simple web-based lookups. It’s tailored for users who require automated data retrieval for various applications. By utilizing XML, the data is structured for easy parsing and integration into your systems. Below, we outline the available XML queries, each designed to retrieve specific aspects of local calling data.
Understanding the XML Query Interface
This interface is structured around distinct queries, each accessible via a unique URL and accepting specific parameters. The output is delivered in XML format, ensuring consistency and ease of use for automated processing. The fields returned in the XML output mirror those available through a standard web interface, ensuring a familiar data structure. Due to the potential for large datasets, especially with broad queries, caching results is highly recommended to optimize performance and reduce redundant requests.
Let’s explore the specific queries available:
Dial Plan Lookup: xmldialplan
Description: Retrieve the dial plan information for a specific Numbering Plan Area (NPA), commonly known as the area code. This query is essential for understanding the geographic boundaries and dialing conventions associated with a particular area code.
URL: xmldialplan.php
Parameters:
npa: Area code (required).
Sample Query:
xmldialplan.php?npa=250This query will return the dial plan details associated with the area code 250.
NPA Listing and Region Details: xmllistnpa
Description: This versatile query allows you to explore Numbering Plan Areas (NPAs) in detail. You can retrieve the region and overlay information for a specific NPA or region. Furthermore, by omitting parameters, you can obtain a comprehensive list of all NPAs. This is invaluable for understanding the geographic distribution of area codes.
URL: xmllistnpa.php
Parameters:
npa: Area code (optional).region: Region name (optional).state: State, province, or territory (optional).
Sample Query:
xmllistnpa.php?npa=905This example retrieves details for NPA 905, including its region and any overlay complexities.
Local Exchange Information: xmllocalexch
Description: Delve into the specifics of local calling areas with this query. It allows you to look up prefixes and rate centers within the local calling area of a specified exchange code. This is critical for determining call routing and cost implications within local networks.
URL: xmllocalexch.php
Parameters:
exch: Exchange code (required).dir: Direction of local calling (optional):1for outbound (default),2for inbound.rconly: Show rate centers only (optional):0to show NPA/NXX (default),1to show rate centers only.
Sample Query:
xmllocalexch.php?exch=015800This query provides local calling area information related to the exchange code 015800.
Prefix-Based Local Calling Area: xmllocalprefix
Description: Similar to xmllocalexch, but focused on prefixes. This query identifies prefixes within the local calling area of a given prefix. Useful for understanding local call boundaries at a more granular prefix level.
URL: xmllocalprefix.php
Parameters:
npa: Area code (required).nxx: Prefix (required).dir: Direction of local calling (optional):1for outbound (default),2for inbound.
Sample Query:
xmllocalprefix.php?npa=250&nxx=423This example fetches local calling area prefixes associated with the prefix 250-423.
NPA/NXX Search: xmlprefix
Description: Conduct comprehensive searches for NPA/NXX combinations (area code and prefix). This powerful query allows you to retrieve a wide range of information associated with a specific prefix, including rate center details, geographic region, operating company number (OCN), and more.
URL: xmlprefix.php
Parameters:
npa: Area code (optional).nxx: Prefix (optional).x: Block (optional).rc: Rate center name (optional).region: Region (optional).state: State/province/territory/Caribbean country (optional).country code: Country code (optional).switch: CLLI code (optional).lata: LATA code for rate center (optional).ocn: OCN (operating company number) code (optional).blocks: Show thousands-blocks (optional):1to show, otherwise do not show.pastdays: Past activity (optional).nextdays: Future activity (optional).udate: Changes since this date (YYYYMMDD) (optional).
Sample Query:
xmlprefix.php?npa=250&nxx=423This query retrieves detailed information for the prefix 250-423.
Rate Center Search: xmlrc
Description: Focus your search on rate centers. This query enables you to find rate center details based on various criteria, including NPA, rate center name, geographic location, and LATA/LIR codes. Rate centers are fundamental to understanding call rating and routing.
URL: xmlrc.php
Parameters:
npa: Area code (optional).rc: Rate center name (optional).region: Region (optional).state: State/province/territory/Caribbean country (optional).country code: Country code (optional).lata: LATA code for rate center (optional).lir: LIR (local interconnection region) code (optional).ocn: OCN (operating company number) code (optional).udate: Changes since this date (YYYYMMDD) (optional).
Sample Query:
xmlrc.php?npa=867This example provides rate center information associated with the area code 867.
Rate Distance Calculation: xmlrcdist
Description: Determine the rate distance between two rate centers and crucially, whether a call between them is considered a local call. This is essential for accurate call cost calculation and routing decisions.
URL: xmlrcdist.php
Parameters:
npa1: Area code of the first location (required).nxx1: Prefix of the first location (required).npa2: Area code of the second location (required).nxx2: Prefix of the second location (required).
Sample Query:
xmlrcdist.php?npa1=416&nxx1=423&npa2=905&nxx2=778This query calculates the rate distance between prefixes 416-423 and 905-778 and indicates if it’s a local call.
