LTI (Low Tech Interface) vs. SOA (Service Order Administration)
Interacting with NPAC has evolved greatly since the inception of local number portability. As
each administrator has been assigned, advances and implementation of newer technologies
have redefined definitions surrounding LNP.
Previously, the LTI, or low tech interface, required accessing hardware to connect to a virtual
private network (VPN) and required users to have a physical, on-hand, RSA key that they would
need to input in order to access the appropriate systems. In contrast, SOAs are available that
provide browser-agnostic GUIs accessible through a simple username/password-protected portal.
In addition, XML-based APIs are available to those looking to programmatically send information
Today, the low-tech interface is a browser-based, browser-agnostic, portal/GUI – gone are the
days of routing traffic through a VPN and requiring an RSA key. While this is a fantastic enhancement
to the LTI, a SOA/API connection still offers many benefits. APIs are still preferred, as technology
standards are continuously evolving, and automation is becoming more and more prominent
across the industry.

When we look at the above features, we can instantly see how local number porting has evolved
from an outdated, mundane, low-tech interface to the SOA platform that removes complexities,
offers automation, and is considerably more user-friendly. A key feature to note is the SOA’s
ability to be offered as an API. This allows businesses to integrate the SOA platform directly into
their existing systems – significantly reducing onboarding time and employee learning curve.
Besides changes in regulations, the driving force behind these technological advances is competition.
It’s the opportunity to provide the best platform to CLECs, ILECs, VoIP providers, wireless,
and wireline businesses that not only save them time but save them money while reducing human error.
