AT&T ATM
AT&T’s ATM customers continue to migrate to IP and Ethernet services. Consequently, AT&T’s ATM service has changed little over the past six months, with the exception of a price increase for port speeds up to DS1. (8/1/2008)

Qwest ATM
ATM demand may be on the decline, but Qwest continues to support the service for enterprise customers. However, the carrier no longer publishes detailed filings for its interstate ATM services. (4/24/2009)

Sprint Nextel SprintLink ATM, ATM over Peerless IP
Sprint has operated its SprintLink ATM and ATM over Peerless IP services for years now, and has been migrating conventional ATM customers to these IP-based services – though some customers prefer to move directly to MPLS IP VPNs. (5/12/2009)

Verizon ATM
Verizon ATM services offer wide regional, national, and international reach, comprehensive features, and competitive SLAs. Verizon received forbearance for its FCC tariffed regional services in 2007, making competitive comparisons difficult. (8/14/2008)

ATM Buying Criteria

• Reliability
  • With highly sensitive ATM applications such as data transfers between banks and as Internet access becomes increasingly mission critical, customers cannot afford network outages.
• Pricing
  • Although best of breed has traditionally been the primary influence over ATM service provider selection, pricing is growing in importance as ATM technology matures and competitors achieve parity on many service metrics.
• Features
  • As the number of available port, PVC/SVC, NNI, and other ATM service options increases, there is tension among the numerous ATM service components as customers make tradeoffs between capability and cost. To a significant extent, complexity is driving the evolution of managed ATM services.
