Document description: 

This document is a guide to orient the SS7 translation engineer/technician on the nature of 9-1-1 Mobile Switching Center (MSC) to SR translations. It is not in the scope of this document to explain exact details of any particular 9-1-1 SR, but to act as a way to understand the dynamics of these types of translations.

As stated earlier, this document is secondary to any network disclosure or other translation policy guides from any 9-1-1 Service System Provider. The reader of this document is encouraged to contact the 9-1-1 Service System Provider for any detailed questions on SS7 translations or policy details. The purpose of this Technical Information Document (TID) is to identify and reflect current trends, not to
catalog every SS7 translation requirement for every 9-1-1 Service System Provider. The SS7 Implementation Improvement Working Group seeks to give the reader the knowledge required to better understand and implement service, using supported interconnection methods that exist in the field today.
