Global IPX Transport & Diameter Hub

One IPX. Infinite Interconnect. Powering LTE, VoLTE, 5G, and Beyond.

Global IPX Transport & Diameter Hub

Today’s mobile networks depend on real-time signaling and quality-assured transport across multiple layers — LTE roaming, VoLTE interworking, 5G attach, and beyond. But direct bilateral interconnects are inefficient, slow to scale, and expose your core to operational risk.

USTelco’s Global IPX Transport and Diameter Hub provides a single, resilient, SLA-driven platform to handle all your mobile signaling and transport needs — across LTE, VoLTE, 5G NSA/SA, and IMS-based services.

 

What We Deliver

Multi-Service IPX Backbone

A private, high-availability IPX network engineered for:

  • LTE/5G roaming (S8, S6a, Cx, Gx)
  • VoLTE signaling & media (IR.65/IR.92)
  • IMS interconnect
  • GRX, DNS, SIP & Diameter routing

Diameter Signaling Hub

Instant global access to 500+ LTE/5G roaming partners with:

  • S6a/Cx/Gx/Rx interfaces
  • Home and visited network proxy functions
  • Real-time signaling gateway and session binding

5G Roaming Gateway (NSA/SA)

Future-proofed for:

  • 5G attach, registration, and policy signaling
  • SEPP (Security Edge Protection Proxy)
  • HTTP/2 signaling (in development)

Quality-Driven Transport

  • MPLS and DIA-based delivery with enforced QoS
  • Multiple Class Selectors (CS4–CS6)
  • GTP-C/GTP-U anchoring for S8 traffic
  • Secure, encrypted signaling tunnels with failover

Global IPX Reach

With carrier-grade POPs across North America, Europe, Middle East, and Asia-Pacific, we ensure low-latency, high-reliability transport for both signaling and user plane.
