ANSI-41 MAP Training

ANSI-41 MAP Training Course with Hands-On Exercises (Online, Onsite and Classroom Live)

The ANSI-41 MAP is an application standard that provides a means to perform intersystem handoff and roaming. This ANSI-41 MAP Training course examines the call flow scenarios and the TCAP structure defined in the standard. Also shown, is how the various network entities communicate with each other.

ANSI-41 MAP TrainingDuration: 2 days

  • We can adapt this ANSI-41 MAP Training course to your group’s background and work requirements at little to no added cost.
  • If you are familiar with some aspects of this ANSI-41 MAP Training course, we can omit or shorten their discussion
  • We can adjust the emphasis placed on the various topics or build the ANSI-41 MAP Training Course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the ANSI-41 MAP Training course in manner understandable to lay audiences.
