ATM Service

SPECIFICATIONS

Grow your networking with ATM's capacity, speed, and flexibility
You can easily support multiple applications - video, voice, IP, and data file transfers -- worldwide over a single connection with the multiple CoS provided by Global Crossing ATM Service. Speeds exceeding T-1 or E-1 can be achieved without a full DS-3/E-3 by implementing inverse multiplexing over ATM (IMA) for a cost-effective and reliable solution.


ATM CLASS OF SERVICE OPTIONS

Priority Level Service Option Typical Use
1 CBR SNA, Video, Circut Emulation
2 VBR-rt Voice, Time-Sensitive Data
3 VBR-nrt High Bandwidth Data
4 UBR+ IP Support, Bursting Non-Sensitive Data

PORT SPEEDS

  • 1.5 Mbps to 622 Mbps

PVC

  • 1M to 540M, depending on service option

TRANSMISSION SPEED

  • The Global Crossing ATM OC-48 network utilizes dense wavelength division multiplexing (DWDM) to move traffic at speeds up to 2.5 gigabytes per second -- 16 times faster than conventional ATM networks.

RELIABILITY

  • Lucent CBX500 switches offer high-speed, multiservice capability with unprecedented availability, performance, and throughput -- Lucent GX550 switches provide high-speed ATM trunking and proven DWDM interoperability.
  • Lucent ATM switches, deployed over DWDM, provide an alternative to SONET/SDH for redundancy, higher interface speeds and increased efficiency.
  • Multiple and diverse paths throughout the network.
  • Industry-standard protocol compliance for user network interface, Frame Relay-to-ATM interworking, and Inverse Multiplexing over ATM (IMA).
  • CoS mapping allocates network capacity and assigns priorities for different types of traffic to ensure critical applications run successfully.

SCALABILITY

  • Full range of port speeds on a single platform - NxT1 or E-1 (minimum N=1) to OC-12/STM-4.
  • Inverse multiplexing applications available.
  • Easy Frame-to-ATM interworking.
  • Reliable and efficient IP-to-ATM interworking.

MANAGEABILITY

  • Global Crossing's NavisCore™ and NavisXtend™ Network Management platform allows for greater manageability in provisioning, troubleshooting, reporting, and more.
  • Homogeneous network environment of Global Crossing ATM and Frame Relay service allows for greater performance, reliability, and scalability.
  • Global Crossing provides worldwide managed services capabilities for FR/ATM, including support for your CPE needs. Our capabilities include network and equipment management, design and engineering, implementation, installation, operations and life-cycle management, and equipment rental functions.
