Capitalize on Business Opportunities with a Reliable, Flexible Network

ibm/SIEMless® Ethernet Network Solutions include Layer 2 networking products that deliver the secure high-performance connectivity you need along with the flexibility to adapt to new business applications.

Ethernet provides a secure, reliable, high-performance backbone to help your company manage data growth, drive application performance and securely connect your locations. Ibm/SIEMless Ethernet Network Solutions allow you to customize your business connectivity to keep your data flowing everywhere it needs to go.


Enable Greater Productivity

Connect virtual work groups to reliably communicate across geographic locations with low latency connections.

Cost Savings

Eliminate higher cost private lines. Ethernet offers granular bandwidth options and the ability to upgrade easily with quick turnaround.

Increase Efficiency

Ethernet network architecture offers lower traffic transit delay which effectively supports sensitive business applications.

Ease of Adoption

Ethernet network technology is an extension of your current office LAN network to multiple business locations, therefore your IT staff is already familiar with how to effectively manage.

Optimize Network Resources

Utilize your IT resources for innovation rather than network maintenance.


Ethernet is an enterprise-class network backed by strong end-to-end performance SLAs for latency, jitter and packet loss.

Security and Control

Ethernet Network Solutions utilize dedicated, private connections while you maintain control of your routing to achieve higher security of your traffic.

Digital Transformation Demands a New Network Strategy


ibm/SIEMless Ethernet Network Solutions

Get All the Right Connections

Select the right Ethernet connectivity options to build and support your performance network. ibm/SIEMless offers metro and national cost-effective Ethernet options to handle all of your business applications.

Metro Ethernet

Metro Ethernet service combines the power of Ethernet and optical technologies across metropolitan area networks (MANs) to provide low cost, scalable and secure bandwidth. Metro Ethernet provides local area network LAN-to-LAN connectivity between two or more customer locations within a metro area. Our Metro Ethernet solution is based on distributed Layer 2 switching and shared transport data bandwidth, and is suitable for data applications.


E-Line is a national and metro Ethernet private line service that connects customer sites within and between major metro markets across the United States. It uses Layer 2 Ethernet with dedicated bandwidth in granular steps from 5 to 1000Mbps. It meets the business challenge of eliminating inefficiencies by transporting business-critical information between multiple customer sites and data centers at low latency in point-to-point or point-to-multipoint configurations. E-Line increases return on investment as an economical service that’s still suitable for demanding enterprise applications.

Metro Ethernet Technical Specifications

Metro Ethernet from ibm/SIEMless is a Layer 2 networking service that enables customers to extend their office LAN network to multiple business locations within metro areas.

It’s an ideal solution when evolving from legacy technologies, providing more bandwidth per dollar than the higher cost Private Lines and is more cost effective than MPLS networking solutions—especially for metro applications.


The ibm/SIEMless Metro Ethernet network is a highly robust and reliable network. It’s also:

  • Widely available in metro areas within 35 states
  • MEF certified
  • Designed in a redundant ring configuration with redundant processors and power supplies; utilizes Automatic Failover within the backbone
  • Proactively monitored and maintained 24x7x365 through proven practices to mitigate unexpected outages and downtime
  • Backed by industry leading Service Level Agreements (SLAs)
  • Supported  by end-to-end web-based reporting tools on a per site basis
  • Multiple topology options: Point-to-Point, Multipoint-to-Multipoint and Point-to-Multipoint
  • Supports port-based and VLAN-based services for a wide variety of applications
  • Includes a Network Management Device (NID) at the customer premise to serve as a Monitoring and Management device and as the demark to the customer
  • Prioritization of service (CoS/QoS) available in multiple bandwidth profiles for a variety of applications
  • Deterministic routing enables a low latency connection for critical business traffic

E-Line Technical Specifications

E-Line uses Ethernet over MPLS over a non-oversubscribed dense wave division multiplexing (DWDM) network.

It delivers a marked improvement along point-to-point connections to data centers and storage-area networking including: disaster recovery, business continuity, Internet access, peering and meet-me interconnections. After E-Line is configured for multiplexing (multiple virtual circuits per port from one location routed to other E-Line locations), you can have hub and spoke multi-site connections within or between any E-Line market.

Using E-Line offers many advantages over a traditional private line service. You get the same reliability you depend on with private line. Plus, you also get increased choice of bandwidth granularity, improved operational efficiency, reduced cost and greater flexibility that all together offers increased return on investment.


  • Metro (MAN) & national (WAN) availability in 40 POPs across major cities in 22 states as well as Washington DC. Additional 200+ markets served via NNI backhaul and 3rd party local access agreements
  • MEF, IEEE and ITU compliant
  • Supports point-to-point (EPL) or point-to-multipoint (E-Tree) applications
  • Highly secure. E-Line Ensures your network is not accessible from the outside to unwanted access or traffic while all your traffic remains isolated from other customers on the ibm/SIEMless private line network
  • Bandwidth options of 5Mbps up to 1000Mbps in granular steps
  • Proactively monitored and maintained 24x7x365 through proven practices to mitigate unexpected outages and downtime
  • Backed by industry leading Service Level Agreements (SLAs)
  • Supported by end-to-end web-based reporting tools on a per site basis


Metro Ethernet

A cost-effective Metro Ethernet solution to connect business locations with the MAN as well as a private port to the ibm/SIEMless® MPLS network, businesses can capitalize on efficiency and capabilities of ibm/SIEMless’s broad portfolio to meet their needs.
