Subject: Notice to ANR Pipeline EDI Customers
Notice Text:
ANR Pipeline is transitioning to TC eConnects as our new transactional system. To ensure a smooth transition for our Electronic Data Interchange (EDI) partners, we are implementing the following system updates:

System Updates Include:
 Updated Trading Partner Agreements (TPA) and Trading Partner Worksheet (TPW) documents with current Internet ET/QEDM specifications
 Modified system connection URL
 Updated SSL certificate, IP addresses, and port configurations
 Revised user credentials and updated PGP key requirements

Implementation Process:
ANR has been working directly with each EDI trading partner and requests your assistance in completing the updated TPAs and TPWs, establish connectivity, and configure file transmission protocols for the enhanced EDI environment. Some EDI datasets will require minor adjustments, which we will discuss with you during system testing.

Firewall Configuration Requirements:
TC eConnects requires additional firewall security measures. EDI customers must update their firewall settings to include these IP addresses for uninterrupted connectivity:

Inbound:
159.60.128.255

Outbound:
35.155.206.14
44.246.65.167
52.32.164.193

Important Transition Timeline
Beginning with Gas Day October 1, 2025, all EDI Nominations and Confirmations will process through the new TC eConnects system. For September 30, 2025, ID2 and ID3 cycles, Nominations and Confirmations must be processed manually through ANR GEMS.
