Result of Connection Test between IP-PBX/Business phones and sXGP terminals in FY 2019
XGP Forum (office located in Tokyo, Japan. Chairperson: Yoichi Maeda) has revised "Guideline for Connection Test of sXGP system" and added a test environment using a combination of multi-vendor sXGP equipment in the conncetion test between IP-PBX/Business phone and sXGP terminals. The connection test 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.
Reference: TD-LTE scheme innovates on 1.9GHz Digital Cordless Telephone system
Then, in order to promote the deployment of this method, we informed of the following initiatives.
Reference: Efforts to spread and promote sXGP
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. Based on the guideline, we have conducted tests continuously with participating companies in this Forum since FY 2018 and have achieved good results.
"Reference provision"
・Ordinance on Radio Equipment (MIC No.60 of 2018) Article 49-8-2-3
(Radio equipment of Radio Station used for Time Division・ OFDMA Digital Cordless System)
・ARIB Standard RCR STD-28 “Personal handy phone system ARIB standard RCR STD-28. (Annex AR)"

This time, we revised the guideline to add test items related to RFI(Radio Frequency Interference) with other wireless system (PHS system).
The test was co-hosted by HATS Forum (Secretariat: Communications and Information Network Association of Japan (CIAJ), Chairman: Tadao SAITO, Professor Emeritus of the University of Tokyo) and over successfully.

4. Test organization
XGP Forum(TWG-AdHoc 22 SWG for sXGP-AdHoc TG for interconnectivity) recruited participant corporations and implemented the test.
5. Test Method
Connection test between IP-PBX/Business phones and sXGP terminals was implemented in accordance with "IP-PBX - sXGP Inter-terminal Connection Test Guideline(Version 3)" and "PBX Telecom Server Inter Connection Test Guideline for sXGP Protocol Specification of Terminal Access (HATS-P-104-V3.0)" based on the former.
6. Test Result
（１）Result of connection test with another sXGP compliance equipment
As mentioned below, 8 items(including some option items) were tested with a combination of two models of IP-PBXs from two vendors and one newly added sXGP equipment (EPC, AP) vendor and all of them passed the test.

（2）RFI test of sXGP System with PHS System
As mentioned below, 6 items of RFI test were tested with a combination of 6 types of IP-PBXes/business phones from 6 companies together with sXGP compliant equipment and another wireless system(PHS system)all of them passed the test. HATS Conference issued "Certificate of Qualification" to the companies that also members of HATS among them.
