Private Line Transport (PLT) GeoMax™ - V10.0

History Log

Product Description

Private Line Transport (PLT) GeoMax™ service is a high speed, high capacity, multi-protocol data-networking solution. The service combines dense wave division multiplexing (DWDM) technology with diverse interoffice fiber facilities, 24/7 proactive network monitoring and aggressive service level agreements (SLAs) to provide a total robust finished service. GeoMax uniquely supports both native and proprietary protocols, e.g., IBM mainframes as well as industry standard protocols such as synchronous optical network (SONET) and Ethernet. GeoMax service has the ability to support multiple protocols and applications on a single platform. Another key advantage DWDM technology offers is the transparency to the data riding on it. It is bit rate and protocol independent, thus guaranteeing customers the 100 percent throughput and low latency their applications demand.

GeoMax supports linear and ring configurations.

The components that make up GeoMax are:

  • Premise node - located at the customer's premise, it is equipped with one shelf and common equipment that can support a maximum of 64 wavelengths when fully equipped with 8 shelves.
  • CO node- located in CenturyLink™'s central office, it is equipped with one shelf and common equipment that can support a maximum of 64 wavelengths when fully equipped with 8 shelves.
  • Network Access Channel (NAC) - Fiber Distribution Panel at customer premise connected to a CO Node.
  • Additional shelf - is equipped with common equipment that can support a maximum of 4 protected wavelengths or 8 unprotected wavelengths. Each node can support up to eight shelves.
  • Additional Wavelengths - May be added to either the premise node or central office node to support up to an additional 44 wavelengths.

  • Amplifier node - Optical amplification provides strengthening of the optical signals or wavelengths to support greater distances that reach beyond normal DWDM optical signals.
  • Interoffice transport mileage - Calculated as the air miles between serving wire centers for each Node (e.g., A to B, B to C, C to A).
  • Ports are available in multiple protocols therefore a single system can include both protected and unprotected ports, as applicable.

Private Line Transport GeoMax™ supports linear and ring configurations.

  • There are two linear configurations available:
    • Point-to-Point - This configuration is a two-node system that can support up to 8 shelves at each terminal site (32 protected or 64 non-protected customer interfaces).
    • Linear Optical Add/Drop Multiplexer (OADM) - This configuration has more than two nodes. It can add or drop a customer signal at any of the sites within the same DWDM Band. Linear OADM supports only unprotected connections.
  • There are three ring configurations available:
    • Hubbed Ring - Shelves in the OADM sites have a one-to-one correspondence with the shelves in the terminal site. A Hubbed Ring supports up to eight single-shelf OADM sites or a smaller number of multi-shelf sites.
    • Dual Hubbed Ring - Shelves in the OADM sites have a one-to-one correspondence with the shelves in the terminal site. A dual hubbed ring has two terminal sites.
    • Mesh Ring - This ring configuration enables the customer to connect across three or more customer locations and the ability to add/drop individual customer interfaces (wavelengths) from any location to any location. It supports up to a maximum of 40 shelves and a total of 9 sites.

Private Line Transport (PLT) GeoMax™ service can connect to the following CenturyLink provided services. Connections must be made at a CO Node:

Synchronous Service Transport (SST) over GeoMax is a service option that is available to the customer for the purpose of transporting Digital Signal Level 1 (DS1) and Digital Signal Level 3 (DS3) signals across the customer's GeoMax Network. The customer will order both GeoMax and SST, and cross connect the SST nodes to the GeoMax nodes at the OC-N level. Service and design restrictions do apply, please refer to CenturyLink Technical Publications 77407 & 77346 for further information.

Frequently Asked Questions (FAQs)

1. What are the advantages and disadvantages of DWDM technology?
Key advantages of DWDM technology include transparency (i.e., bit rate and protocol independent) making it an ideal optical solution for supporting a customer's multi-protocol applications. It offers scalable bandwidth and quick service provisioning, enabling the offering of bandwidth virtually on demand. Its transparency allows customers to support multiple protocols and applications with a single platform. Customers have the flexibility to pick and choose the protection that fits their specific needs, down to interface or port level. Some challenges of DWDM technology include limited performance capabilities, still a new and evolving technology, thus customers are still in the early adopting stages.

2. What is included in GeoMax service?
The service includes all the necessary electronics equipment, including the DWDM, fiber facilities, SLAs, and 24/7 monitoring/management service by CenturyLink.

3. What is the SLA for GeoMax?
SLA (Service Level Agreements) consists of the following four parameters. Service Availability, Customer notification, Mean Time to Repair (MTTR) and Installation Guarantee.

4. Are there specific distance limitations?
Distance limitation varies depending on specific customer applications, protocols and characteristics of the fiber facilities involved.

If supported by the customer's specific application, optical amplification or regeneration can be deployed to extend the distance.

5. Where is the DWDM equipment physically located?
GeoMax DWDM equipment is generally located at customer premises or CenturyLink central office (CO). Locating at customer premises allows GeoMax to interface directly with customer equipment, avoiding possible distance limitations. However, in some ring configurations it's necessary for GeoMax DWDM equipment to be located at non-customer locations such as CenturyLink CO.

6. How is the service being managed and monitored?
GeoMax service is being managed and monitored remotely by the CenturyLink Network Operating Center (NOC) located in Salt Lake City, UT. The NOC performs 24/7 proactive network monitoring and management.

7. What are the key customer applications currently supported by GeoMax service?
GeoMax service can support a number of customer applications from data center mainframe connectivity to LAN/WAN internetworking applications. Data center applications can include applications such as data replication, load sharing and Storage Area Networks (SAN). LAN networking such as Gigabit Ethernet and SONET are the other common applications.
