Intro To Enterprise Communications Solutions & Services

Can you think about how big firms and companies handling their communications ?
Can you imagine how much data flows between different departments through an enterprise or big corporation ?

Communication is important and, as some may argue, it's an art. It allows us to convey ideas to one another, collaborate, share, strengthen relationships and forge new ones. ... 

Enterprise communications encompasses all forms of communication, including by phone, email, video conference, Web chat, texting, and more.

It's time now to learn about different systems that enable enterprise with many branches in different countries and with more than 10000 employee to communicate it's operations ..

We have to know about the following :
- Unified communications is a phrase used to describe any communications system, usually a business system, that encompasses a broad range of technologies and applications that have been designed, sold and supported as a single communications platform or as one entity.

- A single, integrated system for enterprise communications is called hosted unified communications and collaboration. ... include unified communications (UC), which refers to the integration of multiple communications channels, with the business phone number at its heart

- B2B telecommunications describes any communications between businesses, as opposed to between businesses and clients or clients and clients. B2B telecommunications providers maintain systems that transmit data, text, sound, voice and video, which allow for direct communications between businesses.

- The Cisco IP phone contains an integrated three-port 10/100 switch. The ports are dedicated connections. Port 1 connects to the Catalyst switch or other device that supports voice-over-IP.

Data Services are telecommunication products that are provided by a Local Exchange Carrier (LEC), a Competitive Local Exchange Carrier (CLEC), or a Long Distance Company.  These types of services are primarily designed to connect multiple company sites so that they all look like one network.  Internet Access also falls into this category because of the Internet's increasing use as a data transport through VPNs and SD-WAN.

Leased Lines - connect multiple locations, that are geographically separated, and consolidate them into a common backbone network.  Digital Wide Area Network (WAN) connections can be point-to-point T-1s/DS3s, multiplexed 56K lines, or optical circuits like OPT-E-MAN, OPT-E-WAN, GIG-A-MAN or Switched Ethernet.  

Digital Subscriber Line (DSL) - is a high speed Internet Access connection that is delivered on a Business Access Line (POTS) by a technology called line sharing.  The DSL service does not effect the voice use of the POTS line.  The bandwidth of a DSL line is contingent on the quality of the POTS line and the distance from the DSL Central Office or DSL remote repeater.  A DSL line comes with either a static or dynamic IP Address.

Dedicated Internet Access (DIA) - is a permanent connection between a company's LAN environment and the Internet.  These connections are usually provided on a T-1, DS3 or similar high speed circuit.  The bandwidth provided by these products is guaranteed at all times.  The circuit can be provided with a managed router so that the carrier can closely monitor the performance of the circuit.  Ethernet based DIA is also available, but is very difficult to provision.  The time frames to install Ethernet based DIA can easily be in excess of six months.

Virtual Private Network (VPN) - A VPN is a private network that uses a public network such as the Internet to connect users or remote sites together in a secure manner.  Instead of using a dedicated connection, such as leased-line direct circuits, the VPN option uses tunnels routed over the Internet from the company’s private network to another location on the company's network.  This approach uses a business’s existing connection to the Internet and requires IP Security (IPSec)-compliant VPN gateway equipment at the enterprise locations.  While relatively secure, VPNs are subject to latency and security issues inherent in using the public Internet as a transport device for private data.

Voice Services are telecommunication products that are provided by a Local Exchange Carrier (LEC), a Competitive Local Exchange Carrier (CLEC), or an Internet Service Provider (ISP).  These types of services can range from simple dial tone like POTS lines or sophisticated services like VoIP that dynamically allocates voice services and Internet Access over the same line. 

Business Access Lines (POTS) - provide basic dial tone to analog telephones or simple telephone Key Systems.  These lines are sometimes refered to as POTS (Plain Old Telephone Service) lines.  A single, local telephone number is assigned to the line and the ability to make local calls and receive calls is inherent with the service
