Transparent LAN Service (TLS)

Overview

Lower the Cost of Connecting Multiple Sites

Transparent LAN Service (TLS, aka Switched Ethernet Services) gives you the opportunity to offer your customers lower costs for data communications at native Ethernet speeds between sites within many Verizon metropolitan service areas. TLS is available in two service types: Ethernet Multipoint Service (EMS) and Ethernet Relay Service (ERS) with multiple Class of Service options.

The fiber-based service eliminates the need for Frame Relay or ATM cards, reducing the costs usually associated with fast packet services. And, because this access, switching and transport service operates on a shared backbone, it offers additional economies.

How It Works

TLS is an all fiber-based, metropolitan area LAN interconnecting service.

TLS connects customer locations together at native LAN speeds and Ethernet interfaces of 10,100 and/or 1,000 Mbps Ethernet.

LANs are extended over a dedicated fiber loop into their local Verizon wire center, where Central Office based switches provide connectivity to circuits from the other locations, or access to a shared backbone from transport to other local wire centers if needed.

Benefits

Cost effective service for implementing Wide Area Network (WAN) or Metropolitan Area Network (MAN)
Verizon's unmatched fiber footprint within service areas simplifies connecting widely separated customer locations
24 x 7 network monitoring assures reliability and customer satisfaction

Applications

Database replication
Sharing common databases
Archiving for Storage/Back-ups
Teleworkers
IP telephony
Centralizing e-mail servers now dispersed across multiple locations.

Description

Verizon Transparent LAN Service provides for data communications at native LAN speeds between two or more sites in many Verizon-served metropolitan areas. It supports 10 Mbps Basic Ethernet, 100 Mbps Fast Ethernet and 1 Gbps Gigabit Ethernet.

Features & Options

Ethernet Multipoint Service (EMS aka E-LAN) provides fully meshed, any-to-any connectivity, making it ideal for LAN to LAN networking. It is configured by connecting UNIs with one multipoint to multipoint EVC or VLAN and provides full port speed with two Class of Service options - standard and real time.
Ethernet Relay Service (ERS aka EVPL) utilizes point to point Ethernet Virtual Connections (EVC) to define site to site connections. Can support multiple EVC to enable and hub and spoke configuration. ERS supports a wide variety of EVC bandwidth options that enables incremental bandwidth scaling to meet your customers growing network requirements. EVCs are offered in 1 Mbps increments from 1-10 Mbps, 10 Mbps increments from 10-100 Mbps, and 100 Mbps increments from 100-1000 Mbps. ERS supports three Class of Service options - basic, priority and real time.

Availability

Effective as of March 30, 2007, Verizon is grandfathering Ethernet Transparent LAN Service (Ethernet TLS) in its FCC Tariff Nos. 1 and 20 (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 Ethernet TLS under a private carriage arrangement.

Following the grandfathering of Ethernet TLS in the Tariffs, if you wish to place any new orders for Ethernet TLS, you will need to enter into a private carriage arrangement with Verizon for a comparable service. Please note that there are several rate elements, such as Ethernet Virtual Circuits (EVCs), Interoffice Mileage, and Customer Service Management (CSM) that are available on a month-to-month term only.

If you have an Ethernet TLS 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 Ethernet TLS under the Tariffs, you may not make any moves, additions, or changes to such Ethernet TLS, and may not renew or extend the term of the Ethernet TLS beyond the end date of its current term.

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. All services are not available in all areas, and are subject to availability of facilities and equipment.

Features

ERS offers greater scalability than Frame Relay, ATM or private line services because the service can be updated in granular bandwidth increments from 1 Mbps up to a full gigabit.

TLS also interworks with Verizon's IP-VPN offering, enabling the creation of heterogeneous networks with Ethernet, Frame Relay, ATM and Private Line access options.

Applications

Detailed Information

TLS is an all fiber-based, metropolitan LAN interconnecting service. TLS connects customer locations together at native LAN speeds and Ethernet interfaces of 10,100 and/or 1000 Mbps Ethernet. LANs are extended over a dedicated fiber loop into their local Verizon wire center, where Central Office based switches provide connectivity to circuits from the customer's other locations, or access to a shared backbone for transport to other local wire centers if needed.

TLS is available in two service models:

Ethernet Multipoint Service (EMS) service type:

Ideal for Multipoint to Multipoint applications such as intra-company voice and LAN to LAN data
Offers simple, connectionless and any to any connectivity
Transparent to customer VLANs and Layer 2 control protocols

Class of Service Option

Real Time is offered on a per-UNI basis designed to support packet voice applications over the multipoint to multipoint service

Ethernet Relay Service (ERS) service type:

Point to point EVCs offer predictable performance
One or more EVCs may be allowed per UNI depending on the UNI service configuration
Ideal for voice, video and real time data
Service-multiplexed UNI

Class of Service Option

Real Time is designed for packet voice, video and other applications requiring tight guarantees of frame delay, frame jitter and frame delivery performance.

Priority Data is designed for data applications requiring guarantees of frame delivery performance.

Basic is designed for data applications that require no guarantees or performance and where cost per Mbps is the key requirement

Benefits

Cost effective service for implementing Wide Area Network (WAN) or Metropolitan Area Network (MAN)
Verizon's unmatched fiber footprint within service areas simplifies connecting widely separated customer locations
24 x 7 network monitoring assures reliability and customer satisfaction

Speeds

10 Mbps
