Result of Connection Test between IP-PBX/Business phones and sXGP terminals

XGP Forum (office located in Tokyo, Japan. Chairperson: Yoichi Maeda)  has revised "sXGP system Test Guideline" , extended the scope of connection test to business phone as well in addition to IP-PBX and met with a good result.

XGP Forum has been standardizing a new TD-LTE-based wireless technology, license-free ”sXGP system”, as a radio station which uses 1.9GHz band and vigorously participating in the review meeting of technical requirements set up by Information and Communications Council(“ICC”) under MIC.

Then, in order to promote the deployment of this method, we informed of the following initiatives.

In response to ICC’s preliminary answer on March 31, 2017 and amendment enforcement of ministerial order for sXGP systems on October 1, as well as the issuance of standard specification by ARIB, XGP Forum issued test guidelines. Connection test conducted based on the guideline in January 2018 met with a good result.

In addition to this, we have revised the test guideline by adding some additional test items and extended the scope of connection test to business phone as well in addition to the previous IP-PBX.

The test was co-hosted by HATS Conference (Secretariat: Communications and Information Network Association of Japan (CIAJ), Chairman: Tadao SAITO, Professor Emeritus of the University of Tokyo) and sponsored by BB Backbone Co., Ltd. (Head office: Tokyo Minato-ku, Representative Director: Junichi Miyagawa) and over successfully.
