Cable Broadband is a high speed internet service that runs over the existing cable TV infrastructure. It is many times faster than dial up access and typically offers higher speeds than DSL. Pricing tends to be the same as like speed DSL or other shared high speed internet services.
Dedicated Internet Access (DIA) is connectivity from a user’s location to the Internet. DIA is comprised of two separate components: the local loop and the DIA port. The local loop is the physical connectivity from the user’s location to their DIA provider’s Point of Presence (POP). The local loop can either be ordered through the DIA provider, or through an alternate carrier of the customers choosing as customer provided access. The DIA port acts as the mechanism that allows for Internet access and is typically not oversubscribed.
Digital Subscriber Line (DSL) is a family of technologies that provides digital data transmission over the wires of a local telephone network. DSL originally stood for digital subscriber loop. In telecommunications marketing, the term Digital Subscriber Line is widely understood to mean Asymmetric Digital Subscriber Line (ADSL), the most commonly installed technical varieties of DSL. DSL service can be delivered as a stand alone product or simultaneously with regular telephone on the same telephone line as it uses a higher frequency band that is separated by filtering.
The data throughput of consumer DSL services typically ranges from 384 KB/s to 20 MB/s in the direction to the customer, depending on DSL technology, line conditions, and service-level implementation. Typically, the data throughput in the reverse direction, i.e. in the direction to the service provider is lower, hence the designation of asymmetric service, but the two are equal for the Symmetric Digital Subscriber Line (SDSL) service.
Ethernet Private Line (EPL) is a data service providing a point-to-point Ethernet connection between a pair of dedicated User-Network Interfaces (UNIs), with a high degree of transparency. EPL is implemented as a point-to-point Ethernet Virtual Connection (EVC) which, unlike Ethernet Virtual Private Line (EVPL), does not allow for Service Multiplexing, i.e., a dedicated UNI (physical interface) is used to accept all service frames and map them to a single EVC.
Frame Relay is a telecommunication service designed for cost-efficient data transmission for intermittent traffic between Local Area Networks (LANs) and between end-points in a Wide Area Network (WAN).
Frame relay puts data in a variable-size unit called a frame and leaves any necessary error correction (retransmission of data) up to the end-points, which speeds up overall data transmission. For most services, the network provides a Permanent Virtual Circuit (PVC), which means that the customer sees a continuous, dedicated connection without having to pay for a full-time leased line, while the service provider figures out the route each frame travels to its destination and can charge based on usage. An enterprise can select a level of service quality - prioritizing some frames and making others less important.
Frame Relay requires a dedicated connection during the transmission period. It's not ideally suited for voice or video transmission, which requires a steady flow of transmissions. However, under certain circumstances, it is used for voice and video transmission.
Metro Optical Ethernet (MOE) service combines the power of Ethernet and optical technologies across metropolitan area networks (MANs) to provide low cost, scalable and secure bandwidth. MOE provides local area network (LAN)-to-LAN connectivity between two or more customer locations within a metro area. MOE is based on distributed Layer 2 switching and shared transport data bandwidth, and is suitable for data applications.
MPLS is a highly scalable, protocol agnostic, data-carrying mechanism.
In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular data link layer technology, such as ATM, frame relay, SONET or Ethernet, and eliminate the need for multiple Layer 2 networks to satisfy different types of traffic. MPLS belongs to the family of packet-switched networks.
Point to Point circuits, also known as Private Lines, are circuits that are utilized for connectivity between two locations. Customers can utilize this technology to connect host and remote locations to create a secure dedicated WAN instead of using a service like Frame Relay, ATM, MPLS or other IP VPNs.
Point to point circuits can also be used by the customer to connect to a provider's POP for DIA, dedicated voice or other applications when provisioned through their carrier as a "customer provided loop".
This allows the customer to maintain control of their connectivity with the ability to move to a different provider POP if necessary.
Each point to point circuit is distance sensitive, meaning that the price for the circuit will be dependant on the mileage between the two locations that are to be connected.
A virtual private network (VPN) links two computers through an underlying local or wide-area network, while encapsulating the data and keeping it private. It is analogous to a pipe within a pipe. Even though the outer pipe contains the inner one, the inner pipe has a wall that blocks other traffic in the outer pipe. To the rest of the network, the VPN traffic just looks like another traffic stream. The term VPN can describe many different network configurations and protocols.
(May be associated with Wave Division Multiplex, WDM) - Wavelength Services are dedicated, protected wavelengths from a service provider for the exclusive use of a customer. Wavelength Division Multiplexing (WDM) is service or the sale of discrete wavelengths on a fiber transport facility. WDM transmits multiple wavelengths over a single optical fiber, each data signal using its own wavelength (color band). Wavelength services often are protocol independent.
Wavelength-division Multiplexing (WDM) is a scheme for transmitting two or more separate signals over a single fiber optic cable by using a separate wavelength (color) for each signal.
Centrex is an older PBX-like service providing switching at the central office instead of at the customer's premises. Typically, the telephone company owns and manages all the communications equipment and software necessary to implement the Centrex service and then sells various services to the customer.
No switching equipment resides on the customer premise as the service is supplied and managed directly from the phone company's exchange site, with lines being delivered to the premises either as individual lines over traditional copper pairs or by multiplexing a number of lines over a single fiber optic or copper link. In effect, Centrex provides an emulation of a hardware PBX, by using special software programming at the central office, which can be customized to meet a particular customer's needs. As with a PBX, stations inside the group can call each other with 3, 4 or 5 digits, depending on how large the group, instead of an entire telephone number.
Dedicated Long Distance refers to the access of a long distance provider through a dedicated circuit. By installing a dedicated long distance circuit, customers have the ability to dial long distance calls directly into the provider’s network and avoid local line charges through their local voice carrier.
Dedicated Long Distance circuits are comprised of two separate components: the local loop and the long distance rate charges.
The local loop is the actual connectivity from the customer’s physical location to their Long Distance provider’s POP (Point-of- Presence).
Dedicated Long Distance rates are always better than switched long distance rates.
An integrated T1 is an Internet Protocol (IP)-based solution that integrates local and long-distance voice with Internet access on a single connection. It uses Voice over IP (VoIP) technology to give customers the advantage of using the entire circuit for Internet access when phones are not in use. Voice traffic has priority over data. When phones are in use, the bandwidth is automatically allocated from data to voice.
Integrated T1's are designed to meet the voice and data needs of small and medium businesses. Customers have access to the Internet for data and Internet voice calls, and to the gateway used to make calls to end users on the public switched telephone network (PSTN).
Integrated T1's are geared toward customers that want to retain their existing telephony infrastructure (private branch exchange (PBX), key system and handsets) or upgrade to a new premises-based PBX or key system. Integrated T1's are terminated at the customer’s premises using an integrated access device (IAD). The IAD acts as an aggregation point, sending voice traffic to the existing telephone system and data traffic to an existing local area network (LAN) or to the Internet.
Local Business Lines are plain old telephone service (POTS) providing dial tone and access to local calling. They are typically available as flat business lines or measured business lines depending on your local area and the carrier that is proving the service. Local Business Lines re available with no features or with a wide array of local calling features such as caller ID, hunting, call transfer, three way calling and many more.
(Primary Rate Interface) An ISDN service that provides 23 64 Kbps B (Bearer) channels and one 64 Kbps D (Data) channel (23B+D), which is equivalent to the 24 channels of a T1 line. The advantage of the D channel is that it sends control signals that can dynamically allocate any number of B channels for different applications. For example, one channel can be used for voice, while another can be used for data, while six more can be used for a videoconferencing channel and so on. PRI lines typically use four wire pairs.
The European version is known as primary rate access (PRA) or 30B+D. PRA offers 30 B channels, plus one D channel, and is backward-compatible with E-1 transmission. PRI and PRA both provide a full-duplex (FDX) point-to-point connection through an NT2-type intelligent CPE switching device, such as a PBX or router, for interfacing with the central office (CO) switch. The B and D channels are clear channels of 64 kbps, as signaling and control are out-of-band. The B channels can be used individually to connect on demand to any other ISDN device, and multiple B channels can be bonded and treated as a single fast connection for bandwidth-intensive applications such as data file transfers, videoconferencing, and any multimedia combination. Although the D channel is reserved exclusively for signaling and control, those functions are fairly light. ISDN standards, therefore, provide for non-facility associated signaling (NFAS), which allows a D channel to support up to five PRI connections. PRI requires the extended superframe (ESF) format. Line coding is alternate mark inversion (AMI) with bipolar with eight-zeros substitution (B8ZS).This process is the same combination of techniques used in contemporary T1 circuits
SIP trunks enable the origination and termination of local voice, dedicated long-distance, as well as domestic and international toll-free service across a single broadband connection. SIP trunks routes voice calls from an IP-PBX across secure MPLS communication paths using Session Initiation Protocol (SIP) - a signaling protocol that delivers real-time, IP-based communications. Depending on where the calls terminate, they are either delivered to the Local Exchange Carrier in the customer's area or delivered off-network as a domestic or international long distance call.
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VOIP are IP telephony and Internet telephony.
Internet telephony refers to communications services — voice, facsimile, and/or voice-messaging applications — that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.
Hosted call center solutions allow customers to take advantage of all the features and benefits of a customer premise based call center facility with the added security and redundancy of a carrier grade network implementation. Customers can choose to have their entire call center infrastructure hosted or simply integrate additional hosted functionality with their current premise based call center infrastructure.

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.
A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.
A cloud can be private or public. A public cloud sells services to anyone on the Internet. A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services.
Infrastructure-as-a-Service provides virtual server instances with unique IP addresses and blocks of storage on demand. Customers use the provider's application program interface (API) to start, stop, access and configure their virtual servers and storage. In the enterprise, cloud computing allows a company to pay for only as much capacity as is needed, and bring more online as soon as required. Because this pay-for-what-you-use model resembles the way electricity, fuel and water are consumed; it's sometimes referred to as utility computing.
Platform-as-a-service in the cloud is defined as a set of software and product development tools hosted on the provider's infrastructure. Developers create applications on the provider's platform over the Internet. PaaS providers may use APIs, website portals or gateway software installed on the customer's computer.
In the software-as-a-service cloud model, the vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. SaaS is a very broad market. Services can be anything from Web-based email to inventory control and database processing. Because the service provider hosts both the application and the data, the end user is free to use the service from anywhere.
Collocation is the renting of physical space, power and bandwidth on a service provider's premises. Data center collocation allows a small or mid-sized business to save money by storing and running parts of its IT infrastructure off-site instead of building and maintaining a large dedicated data center in-house. For instance, a start-up business might collocate its servers. In such a scenario, the servers are owned by the business but are collocated to save money in overhead costs incurred by things like cooling, physical security or insurance. Some collocation providers also provide technical support for additional fees.
Software as a Service (SaaS) is a model of software deployment over the internet. With SaaS, a provider licenses an application to customers for use as a service on demand, either through a time subscription or a “pay-as-you-go” model. Also known as “software on demand,” the SaaS model allows vendors to develop, host and operate software for customer use. Rather than purchase the hardware and software to run an application, customers need only a computer or a server to download the application and internet access to run the software. The software can be licensed for a single user or for a group of users.
An evolving communications technology architecture which automates and unifies all forms of human and device communications in context, and with a common experience. Its purpose is to optimize business processes and enhance human communications by reducing latency, managing flows, and eliminating device and media dependencies.
