ATMS Technical Summary

ATMS is a transport service that provides reliable and secure delivery of data, voice, and video content in packets referred to as ATM cells. These cells (composed of 53 byte fixed length containers) are delivered via links between ATM switches to comprise a network. ATMS may be delivered as Native ATM or as Emulated ATM but not both, depending on the Agency's requirements. The service footprint covers CONUS, OCONUS, and Non-Domestic locations. The service's performance and reliability in delivering converged data, video and voice applications, makes it an attractive alternative to Private Line or Frame Relay (FR) networks.

The example shown below illustrates some of the key technical requirements satisfied by ATMS. Agencies with both Routine and Critical Service Level Agreements (SLAs) are connected to the contractor's backbone network through contractor-provided access services that include dial-up Integrated Services Digital Network (ISDN), Digital Subscriber Line (DSL), Ethernet, Frame Relay Service (FRS), Private Line Service (PLS), other Agency ATMS, and dial-backup. ATMS can accommodate connections at customer locations via Agency's routers, ATM edge switches, multiplexing/switching devices, PBXs, and host computers. Critical Agency locations requiring high availability may purchase multiple edge switches to provide switch diversity. Inverse Multiplexing capability for ATM (IMA) can provide a scalable and cost-effective solution for customers who choose to optimize WAN resources among existing T1s (NxDS1), without having to purchase DS3 or OC3 circuits.

ATMS Technical Detail

The ATMS solution provides a connection-oriented, transmission service with scalable port speeds of DS-1, DS-3, OC-3, and OC-12. In addition, ATMS provides E-1 and E-3 port speeds for terminations outside the United States. ATMS provides service continuity to FTS2001 contracts.

ATMS supports the following technical capabilities as described in Section C.2.3.2.1.4 of the Networx contracts:

• Quality of Service (QoS) and/or Class of Service (CoS) levels per Permanent Virtual Connection (PVC).
• Bandwidth on demand via scalable CoS.
• Provisioning as a point-to-point virtual connection.
• Network management systems accessibility for querying status, performance statistics, equipment configuration, and fault detection by the Agency's network management staff.
• Multiple PVC speeds from 64 Kbps up to and including OC-12
• Symmetrical PVCs.
• Virtual Path/Virtual Channel (VP/VC) addressing.
• Local access / Local loops.

ATMS allows Agencies to interconnect sites served by ATMS, FRS, PLS, and Ethernet services. Multiprotocol Label Switching (MPLS) is an enhancement to IP/ATM networks that is offered on ATMS. An MPLS backbone creates virtual circuits between MPLS-enabled endpoints on the network in order to speed up connections.

ATMS features are described in Section C.2.3.2.2.1 of the Networx contracts that include:

• Circuit Emulation Services
• Disaster Recovery PVCs
• Port Diversity
• Interworking Services to transparently access Agency locations that use (1) Contractor's FRS, and (2) Contractor's IP networks.
• IMA connectivity
• IP-enabled ATM
• Point-to-Multipoint PVCs

Each Networx contractor may provide variations or alternatives to the offering and pricing for ATMS. The specific details can be found within each Contractor's Networx contract files and pricing notes for ATMS.

For more information on the general ATMS specifications and requirements, please refer to Section C.2.3.2 of the Networx contract for technical specifications and Section B.2.3.2 for pricing.

ATMS Price Basics

ATMS provides connection-oriented data transmission, between user locations, with scalable port speeds of DS-1, DS-3, OC-3, and OC-12. PVCs are distinguished by simplex versus duplex and by bit rate type:

• Variable Bit Rate/real time (VBRrt): A class of ATM service, used primarily for voice, lower quality video, and media, in which bandwidth is made available only as needed but with a enough control of latency and jitter to deliver acceptable application quality.
• Variable Bit Rate/non-real time (VBRnrt): A class of ATM service used mainly for time-critical transaction processing, data transfer, and frame relay-to-ATM internetworking (FRASI) in which bandwidth is made available only as needed but with somewhat less control of latency and jitter than with VBRrt.
• Available Bite Rate (ABR): A class of ATM service, normally used for applications that do not require real-time delivery of data, e.g., local area network (LAN) interconnection, distributed file services, and Frame Relay to ATM Service Interworking (FRASI).
• Constant Bit Rate (CBR): Native Mode or Emulated: A class of ATM service that supports the transport and delivery of services that require a constant, unvarying rate of information delivery, e.g., high quality video, high quality voice, and emulated circuit switching. The cell rate is constant with time
• Unspecified Bit Rate (UBR): A class of ATM service, used for connections that transport variable bit rate traffic for which there is no reliance on time synchronization between the traffic source and destination. There are no flow-control mechanisms to dynamically adjust the amount of bandwidth available to the user.

ATMS is similar to the ATM Service offered on FTS2001 contracts.

Price components required for full end-to-end service for CONUS, OCONUS, and Non-Domestic ATMS:

• • ATMS Port monthly recurring charge per port
  • ATMS PVC monthly recurring charge per PVC
  • DAA Originating and Terminating Wireline Access (MRC) and (NRC)
  • Features ordered as needed by the Agency:
• *Disaster Recovery PVCs
• Port Diversity
• Interworking Services
• Inverse Multiplexing for ATM (IMA)
• IP-enabled ATM
  • Service Enabling Devices (SEDs) may be required to implement ATMS. [Please note that SEDs under Networx replace the FTS2001 User-to-Network Interfaces and Access Adaptation Functions (UNIs/AAFs). SEDs may differ between Networx providers. The pricing structure for SEDs provides for either a one-time payment or monthly term payments for purchase, plus a NRC for installation and a MRC for maintenance.]

  * Some or all price components are priced on an Individual Case Basis (ICB). CLINs with ICB prices are not available in the unit pricer.

  Example 1: ATMS CONUS Dedicated T1

  
  

  

  
  

  • ATMS Port: Choose CLIN 53009 (Routine Port T1 MRC)
