BT Opens Global IP Exchange In Singapore For Fixed And Mobile Operators

Clement Teo

For hosted voice service providers and mobile network and fixed-line operators, BT’s launch of a major global IP exchange (GIPX) hub in Singapore could be good news. Set up to meet the demand for growing traffic over its IP Exchange platform, this is the third announcement I’ve seen from telcos in this region in the space of two months — the others being Telstra Global Services and Tata Communications.

BT’s wholesale service enables communications providers to connect VoIP to VoIP and VoIP to traditional voice calls, and runs over its MPLS network — i.e., a private IP network.

I spoke with Beatriz Butsana-Sita, managing director of BT Global Services and Global Telecom Markets, who explained that delivering the GIPX service closer to BT’s wholesale customers in this region serves to minimize their cost to interconnect to BT’s clearinghouse. “GIPX also provides an opening into BT’s platform for advanced IP services that we continue to invest in,” she said.

The telco is also working on a number of developments to further expand the service, such as the ability to support mobile 4G and provide video interoperability between different devices and networks.

The BT GIPX Singapore hub:

  • Provides a local switch function in the Asia Pacific region. This brings BT’s GIPX service closer to customers’ networks.
  • Acts as a multiservice GIPX point of presence (PoP). This helps address the growing demand for interconnect services in the region. The services that benefit from and are supported by GIPX include fixed and mobile voice (at a range of qualities, e.g., high-definition voice); fixed, mobile, and wireless data; roaming services; and videoconferencing.

4G Data Exchange: Another Option Arises For Mobile Operators

Clement Teo

At a briefing last week, I spoke with Tejaswini Tilak, global head of carrier services at Telstra, who updated me on its newly launched mobile operator IPX (IP Exchange) platform. Marketed as the Telstra Global IPX Service, this service aims to enhance international roaming and next-generation mobility services for operators seeking to exchange long-term evolution (LTE) data traffic. The service promises:

  • An optimized network. Using a single channel, the Telstra Global IPX Service allows mobile operators to optimize their networks to accommodate growing mobile data consumption while providing end users with a consistent customer experience.
  • Greater efficiency. This is possible as it runs over a private network — Telstra Global’s own managed IP MPLS core network — which can maximize traffic on both legacy and new mobile platforms. 
  • Diameter signaling support. Telstra provides support for diameter signaling, a relatively new protocol that works with core IMS on IP data traffic. Tilak claims that Telstra will be able to set up multiple roaming agreements by acting as a diameter signaling hub and providing interoperability and mediation between different diameter deployments among mobile operators.
