How is business telecom different from consumer telecom? Business telecom contracts typically include a Service Level Agreement (SLA). SLAs are guarantees that your telecom services “uptime” will be maintained at a certain level. Consumer telecom services typically do not include an SLA.
Like thousands of other people, I run a business from my house. Why can’t I get business telecom services at a residential address? It’s all about the SLAs (see above). Telecom carriers take their SLAs seriously and make sure they have business-grade infrastructure all the way to commercial office locations. Not even the giant carriers can swing the investment necessary to contractually ensure 99%+ uptime to every residential address they serve.
If we switch carriers, can we keep our phone numbers? In most cases, yes.
What things do people typically forget about when specifying telecom needs? Top two “whoops we forgot” items are alarm systems and fax machines. Each of those may have unique connection requirements.
How does Wiresurfer make money? We receive a fee from the telecom carrier.
Are there any fees to use the Wiresurfer marketplace? Absolutely not. It’s free. Wiresurfer represents all the major U.S. telecom providers’ and we are paid by the telecom providers for any products and services ordered.
What telecom products and services can I order on Wiresufer? Internet, VoIP, IP Phones, Unified Communications as a Service (UCaaS), POTS lines, wireless Internet.
Can I order residential service? Yes if it is ordered under a business.
Can I talk to a live person? By all means. We know telecom can be technical and tedious in nature. You can speak to a Wiresurfer telecom expert anytime by calling.
Is my company contracting for a telecom product with Wiresurfer or the chosen telecom provider? You are contracting with the telecom carrier directly which is providing the telecom service as chosen. All paperwork is with the telecom carrier. You become a direct customer of that telecom carrier. Wiresurfer enables the entire process.
Who installs the telecom service? The telecom carrier will manage and install all the services ordered. Once contracts and orders are submitted, the telecom carrier assigns an installation manager that is in communication with you until services are fully up and running.
Who bills for the telecom services? The telecom carriers bill you for all services directly. You become a contractual customer of the telecom carrier. Carrier invoices are issued monthly after services are installed, tested and turned up.
What happens if there is a problem with my order? Once Wiresurfer submits the order with signed contracts, you will receive email confirmation from the telecom provider welcoming you as a new customer. There will be main contacts included for you from the telecom provider to engage with going forward and if there are any problems. We want the experience to be delightful thus you may at any time contact us as well to assist. We are telecom people so we know how to get things done.

ADSL (Full Rate Asymmetrical DSL) ADSL offers differing upload and download speeds and can be configured to deliver up to six megabits of data per second (6000K), from the network to the customer, that is up to 120 times faster than dial-up service and 100 times faster than ISDN. ADSL enables voice and high-speed data to be sent simultaneously over the existing telephone line. This type of DSL is the most predominant in commercial use for business and residential customers around the world. Good for general Internet access and for applications where downstream speed is most important, such as video-on-demand. ITU-T Recommendation G.992.1 and ANSI Standard T1.413-1998 specify full rate ADSL. ITU Recommendation G.992.3 specifies ADSL2 which provides advanced diagnostics, power saving functions, PSD shaping, and slightly better performance than G.992.1. ITU Recommendation G.992.5 specifies ADSL2Plus, which provides the benefits of ADSL2Plus twice the bandwidth so that bit rates as high as 20 Mb/s downstream can be achieved on relatively short lines.
Asynchronous Transfer Mode (ATM) A cell relay network protocol which encodes data traffic into small fixed-sized (53 byte: 48 bytes of data and 5 bytes of header information) cells instead of variable-sized packets, as found in packet-switched networks such as the Internet Protocol or Ethernet. It is a connection-oriented technology, in which a connection is established between the two endpoints before the actual data exchange begins.
Availability The amount of time that a system is available during time periods when it is expected to be available. Availability is often measured as a percentage of an elapsed year. For example, 99.95% availability equates to 4.38 hours of downtime in a year (0.0005 * 365 * 24=4.38) for a system that is expected to be available all the time. (Provided by SNIA)
Backbone (1) The part of a network used as the primary path for transporting traffic between network segments. (2) A high-speed line, or a series of connections, that forms a major pathway within a network.
Bandwidth (1) Measure of the information capacity of a transmission channel. (2) The difference between the highest and lowest frequencies of a band that can be passed by a transmission medium without undue distortion, such as the AM band – 535 to 1705 kilohertz. (3) Information carrying capacity of a communication channel. Analog bandwidth is the range of signal frequencies that can be transmitted by a communication channel or network. (4) A term used to indicate the amount of transmission or processing capacity possessed by a system or a specific location in a system (usually a network system).
Broadband (1) The ability of a system to carry a multitude of signals simultaneously. In data transmission, it denotes transmission facilities capable of handling frequencies greater than those required for high-grade voice communications. The higher frequency allows the carrying of several simultaneous channels. Broadband infers the use of a service provider signal rather than direct modulation (i.e., baseband).

Cable Modem Termination System (CMTS) Equipment used to provide high-speed data services, such as cable Internet or Voice-over-IP, to cable subscribers.
Carrier A company that provides communications circuits. Carriers are either “private” or “common.” A “private” carrier can refuse service. A “common” carrier cannot. Most of the carriers in our industry (the local phone company, AT&T, MCI WorldCom, US, Sprint, etc.) are common carriers. cf. Service Provider.
Category 5 Cable (CAT 5) An unshielded, twisted-pair cable designed for high signal integrity. The twisting of the cable reduces electrical interference, and the plastic insulation has low dispersion, so the dielectric constant of the plastic does not depend greatly on frequency.

(3) The smallest subdivision of a circuit that provides a type of communication service, usually a path with only one direction. (4) A communications path, or the signal sent over that channel. Through multiplexing, several channels can be transmitted over an optical channel.
Collocation Multiple service providers sharing a single facility for housing physical network equipment are said to be collocated. In deregulated telecommunications markets, competing service providers often need to share (indeed, may be required by law to share) a number of physical facilities, such as a central office building and long distance trunks. Typically, established incumbent service providers are required to share their existing facilities with newer competitive service providers. The fact of collocation may limit the amount of space available to a service provider in a given facility, making it desirable for the service provider to fit a large amount of equipment in a comparatively small space.
