Carrier Network Routing Directory

TNS Carrier Network Routing Directory (NRD) is a multi-protocol centralized registry system designed to simplify your routing.  NRD empowers your company with a single platform to manage your peering and interconnection relationships, legacy or next generation, for improved routing.  By determining the carrier of record, traffic can be routed directly and new revenue generation is simplified. 

Key Features

Carrier type enumeration

Allows details of carrier and line type information to be returned in the query responses.

Local Routing Number (LRN) override

Allows traditional SS7 customers to receive a pseudo-LRN to peer with IP-based service providers.

Do-not-call registry

Provides access to our do-not-call list to help keep you in compliance.

CIC override

Send toll-free traffic directly to RESPORG.

Key Benefits

Reliability

Highly scalable robust platform. The service grants your company access to information critical to the accurate routing and billing of inter-carrier communications, such as voice and mobile data services. We make available an up-to-date, portability-corrected image of the entire public dial plan, as well as authoritative information sourced directly from the service provider having the right-to-use the telephone number.

Cost savings

Route calls to least cost partners or bypass the PSTN when possible with real-time carrier of record data. NRD registry hosts a robust repository of global telephone numbers and carrier of record information that identifies portability corrected carrier ownership information. In response to lookups, the registry returns service provider ID (SPID), and, when available, the Location Routing Number (LRN) of ported and pooled numbers.

Peering

Registry also hosts a multi-party shared registration system that furnishes service providers with sophisticated data-sharing capabilities featuring safeguard controls designed to uphold data-sharing policies. Using our secure portal, service providers can self-administer data and selectively grant access, in whole or part, to partners.

Flexibility

Built with a lot of flexibility in mind as it supports ENUM, SIP and TCAP over SIGTRAN queries. And it also supports various NAPTR responses to queries.

Visibility

With the real-time business intelligence reports, customers can have visibility on detailed traffic flow thus allowing the customer to prioritize and establish direct peering with proffered carriers.

Deployment options

TNS Carrier ENUM can be accessed either through the Central Replica at TNS data centers or by deploying a TNS Carrier ENUM Local Replica server at the customer’s data center.
