Adapt to Growing Business Communications Needs Reliably and Cost-Efficiently with Domestic Private Lines

To adapt and compete in today’s fast-moving markets, you need to be able to extend the reach of your internal business communications cost-efficiently. ibm/SIEMless Domestic, Metro and International Private Line Services provide exceptional reliability, accessibility, and scalability to protect your critical business traffic from uncertainty and downtime. An end-to-end private connection lets your company deliver growing volumes of data, video, and voice quickly and securely over greater distances. Advanced synchronization technologies ensure high-speed performance for all your private line traffic, from DS-0 to OC-N. Deployed over the ibm/SIEMless network, a full range of services are available to meet all your private line needs through a single solution.

Domestic Private Line Service Features

  • Robust service level agreements (SLAs) for 99.999% network availability
  • Support for voice, video, and Internet
  • Four-fiber, bidirectional line-switched ring (BLSR) technology
  • Multiplexing (muxing) available at DS-1, DS-3, and OC-N circuit levels based on customer-selected options and restrictions
  • Network monitoring and management to achieve high levels of performance
  • Network Diversity® service enhancement (on request and subject to availability) for point-to-point transmission between two ibm/SIEMless points of presence (POPs) as a distinct circuit from your primary on-net circuit. Diversity service is available as follows:
  1. POP diversity
  2. Ring diversity
  3. Route diversity

24/7 customer support

Private Line Service Benefits

  • Supports reliable transport service through secure connections
  • Provides the flexibility to allow you to build network configurations
  • Improves cost efficiency by allowing you to combine multiple incongruent services (data, IP, ATM, voice, video, etc.) over one line with a single channelized interface, and aggregate slower speed services onto high-bandwidth trunks
  • Strengthens security and helps protect the confidentiality of your information through a telecommunications facility dedicated for your use
  • Delivers high performance—SLA includes circuit availability objective of 99.999% end-to-end
  • Ensures reliability through four-fiber, bidirectional line-switched ring (BLSR) technology, the gold standard in synchronous optical networking (SONET); circuits are switched automatically from the working side to the protect side of the ring within 50 ms
  • Provides the flexibility to connect multiple signals and/or locations (e.g. to support point-to-multipoint applications) through multiplexing (muxing)
  • Aids disaster recovery planning and continuity of operations through Enhanced Diversity routing
  • Minimizes delay to accommodate even the most delay-sensitive applications

How ibm/SIEMless Private Line Service Works

ibm/SIEMless™ Private Line Services delivers a fixed capacity of bandwidth for transport of your digital communications traffic, utilizing and conforming to SONET standards that originate and terminate a physical connection at a ibm/SIEMless-specified demarcation point located in the ibm/SIEMless POP. The service extends to and includes the equipment maintained by ibm/SIEMless that is necessary to connect the service to the customer’s interconnection facilities at the ibm/SIEMless-specified network interface points. Interconnection, collocation, and/or local access services are not included as part of the Domestic Private Line service, but may be ordered in conjunction, either through ibm/SIEMless or other telecommunications providers. Digital Private Line service is available at DS-0 (64 Kbps), fractional DS-1 (128 Kbps and up), DS-1 (1.544 Mbps), DS-3 (45 Mbps), and OC-N (155 Mbps and up). Digital Private Line services utilize digital local loops that provide nearly 100 percent end-to-end network availability. ibm/SIEMless DS-1 service can also be configured as clear channel or channelized, and is compatible with virtually all DS-1 systems in use today.
