IntelliLight Entrance Facility (IEF)

Overview

Standby to Transmit . . . Just in Case

Protect entrance facility traffic with survivability. Verizon's IntelliLight Entrance Facility (IEF) service gives long distance providers affordable entrance transport that preserves connecting DS1, DS3, STS1, OC-3/OC-3c and OC-12/OC-12c services. Advanced data services and Verizon Optical Networking STS1, OC3c and OC12c Ethernet-to-SONET mapped services can connect to IEF at equal speed interfaces (STS1, OC3 and OC12). IEF saves money over a dedicated SONET ring entrance facility that costs much more.

Supported by SONET technology and self-healing ring architecture, Verizon's IEF increases service assurance using automatic protection switching and diverse fiber paths. Thus, customers are assured of a reliable standby transmission path for high-capacity services.

How It Works

Two transmission paths prevent interruptions in case of entrance facility fiber failure. Normal routing gives you both working and standby paths over a SONET-based fiber ring.

If a fault occurs, protection switching sends traffic to another path -- automatically.

Benefits

Designed to work with 1-48 STS1 and beyond bandwidth, customers get a SONET technology advantage for protecting entrance facility traffic.
IEF offers pricing economies for DS3s, STS1s, OC3/OC3cs and OC12/OC12cs by only charging for the bandwidth utilized.
Near 100 percent survivability builds confidence in network performance. Verizon's IEF architecture assures service restoration at the entrance facility in under 50 milliseconds.

Applications

Recommend IEF for customer locations having a high volume of DS3s, STS1s, OC3/OC3cs and OC12/OC12cs that require added entrance protection via survivable, self-healing service.
IEF is ideal for customers whose businesses rely heavily on voice, data and video applications.

When Network Integrity Counts . . .

IEF assures it with the best entrance facility protection available.

IEF

Description

IntelliLight Entrance Facility (IEF) is an entrance transport alternative using a shared SONET-based fiber ring. IEF protects your DS1, DS3, STS1, OC3/OC3c and OC12/OC12c services. It offers a standby transmission path for high-capacity services and provides survivability at the local loop.

Availability

Effective as of August 30, 2007, Verizon is grandfathering the IntelliLight® Entrance Facility (IEF) in its FCC Tariff Nos. 1 and 11 (Tariffs). Last year, Verizon received forbearance from certain common carrier regulation for several packet-switched broadband services, as well as non-TDM-based optical networking, optical hubbing, and optical transmission services (Forbearance). In accordance with this Forbearance relief, Verizon will now offer a service comparable to IntelliLight Entrance Facility under a private carriage arrangement. Please note that DS1, DS3, and STS1 rate elements of IEF are excluded from grandfathering as described in this letter, and such rate elements shall continue to be available to you under the Tariffs only.

Following the grandfathering of IEF in the Tariffs, if you wish to place any new orders for IEF, or to renew or extend your existing IEF, you will need to enter into a private carriage arrangement with Verizon for a comparable service. If you have an IEF that is currently on a term plan, you may either continue to purchase such service under the applicable Tariff until the end of such term, or enter into a private carriage arrangement with Verizon to purchase a comparable service. If you decide to continue to purchase such IEF under the Tariffs, you may not make any moves, additions, or changes to such IEF, and you may not renew or extend the term of such IEF beyond the end date of its current term.

Pricing

Pricing for new orders of this service are handled on a contractual basis. Please contact us or call your account manager to discuss your particular needs.

Verizon offers a Special Access Service Guarantee (SASG) based on the length of service interruption and states that “any service outage greater than the specified SASG interval, due solely to a telephone company facility component failure, will result in a credit of 100% of the monthly rate for the applicable rate elements of the affected service. Only one such credit is allowed in a single month’s billing period”. For IntelliLight Entrance Facility the SASG is four hours in the former Bell Atlantic South states and one hour in the former Bell Atlantic North states.

NOTE: The terms and conditions of certain of the services described above are set forth in full detail in Verizon’s FCC Tariffs (Tariffed Services), while certain other services described above are provided on a private carriage basis (Private Carriage Services). For Tariffed Services, any summary of Verizon’s FCC Tariffs (Tariffs) set forth above is being provided for your convenience, but is not intended to provide a complete description of the terms and conditions of the Tariffs. You should not rely on this summary, and should conduct your own review and analysis of the Tariffs. Any failure or error by Verizon to fully or accurately set forth all relevant terms and conditions of the Tariffs shall not be deemed to bar Verizon from exercising its rights under the Tariffs. Notwithstanding anything to the contrary herein, the Tariffs shall govern over any inconsistent provision set forth herein. For all Private Carriage Services, the above summary is provided for your information and reference only. However, the actual terms, conditions, restrictions, limitations and the like for Private Carriage Services will be those set forth in the agreement between the customer and Verizon for such Private Carriage Service and shall govern over any inconsistent provisions set forth herein.

With OC48 Mid Span Meet, the entire bandwidth and the central office ADM are committed entirely to the customer

Detailed Information

With the OC48 mid span meet option, the entire bandwidth as well as the central office add/drop multiplexer (ADM), is committed entirely to the customer. This is due to the linear design and use of CPE (the SONET ADM at the customer premise is solely customer owned). The location of the meetpoint is at a site that ensures the best use of existing resources. The physical interface necessary to connect fiber optic cables with the customer is at a fiber connector panel, situated in a mutually acceptable location allowing access to both Verizon and the customer.

Synchronous Optical Network (SONET) is a set of standards for fiber optic transmission. SONET rings act as an ultra-high speed pipeline for multiple services. A SONET-based network protects your traffic with self-healing rings and automatic protection switching. This provides increased service assurance. IEF generally applies best to customer locations with a high volume of DS1s and/or DS3s requiring added loop protection via survivable, self-healing service.

How it works

IEF utilizes two separate transmission paths to prevent interruptions in the case of a fiber failure in the local loop.
Diagram A: Normal Routing-IEF provides a working and a standby path over a SONET-based fiber ring. In normal circumstances, traffic travels over the working path. The standby path is available in case a fault occurs in the local loop.
Diagram B: Alternate Routing-If a fault occurs, the automatic protection path instantly re-routes traffic to the second path to prevent interruptions.

Speeds

Multiple STS1s (one STS1 is 51.84 Mbps)

Network Guarantees

Verizon offers a service guarantee - four hours for Verizon East (South), and one hour for Verizon East (North). If a service outage exceeds our guarantee then Verizon will refund 100% of the monthly recurring charge of the applicable rate element(s) affected, up to one credit per month.
