Transition from Legacy PTS Services to MyDTCC or DTCC Mainframe Portal
As part of our ongoing efforts to modernize our technologies and provide the best client experience, DTCC will sunset access to its legacy Participant Terminal Services (PTS), also known as TN3270 Terminal, in Q3 of 2025.
Services available in PTS can be accessed through the DTCC Mainframe Portal or MyDTCC, as the point of entries to DTCC services.
Client Administrators (Super Access Coordinators / Access Coordinators) should make certain that all user identities accessing PTS are defined in the Customer Registration System (CRS).
Refer to our Transition from Legacy PTS Services to MyDTCC or DTCC Mainframe Portal Online Help Guide to learn about how to work in the equivalent function that is replacing a PTS function.
