AT&T domain suppliers

Date	Domain	Partners
Sept 2009	Wireline Access	Ericsson
Feb 2010	Radio Access Network	Alcatel-Lucent, Ericsson
April 2010	Optical and transport equipment	Ciena
July 2010	IP/MPLS/Ethernet/Evolved Packet Core	Alcatel-Lucent, Juniper, Cisco

The table shows the selected players in AT&T's domain supplier programme announced to date.

AT&T has stated that there will likely be eight domain supplier categories overall so four more have still to be detailed.

Looking at the list, several thoughts arise:

• AT&T has already announced wireless and wireline infrastructure providers whose equipment spans the access network all the way to ultra long-haul. The networking technologies also address the photonic layer to IP or layer 3.
• Alcatel-Lucent and Ericsson already play in two domains while no Asian vendor has yet to be selected.
• One or two more players may be added to the wireline access and optical and transport infrastructure domains but this part of the network is pretty much done.

So what domains are left? Peter Jarich, service director at market research firm Current Analysis, suggests the following:

• Datacentre
• OSS/BSS
• IP Service Layer (IP Multimedia Subsystem, subscriber data management, service delivery platform)
• Voice Core (circuit, softswitch)
• Content Delivery (IP TV, etc.)

AT&T was asked to comment but the operator said that it has not detailed any domains beyond those that have been announced.
