John Shepler Digital business telephone systems can be based on one of two important technology standards. Both are digital standards, as opposed to the analog single line or Key telephone systems found in very small phone systems. VoIP is the newer technology thought to need completely different equipment and more likely chosen for brand new installations.
This is accomplished with a remote computer connected to the distant network.
Whereas remote control refers to taking control of another computer, remote access means that the remote computer becomes a work station on the network. Communication between the network facility equipment and the remote computer is accomplished through a data link. The only difference between a remote user and workstations connected directly to the network is slower data transfer speeds.
Remote Access is also useful when you want to connect local office computers with corporate networks. This allows the business to share resources as if all computers are connected to the same LAN. Dial-up remote access is when a client uses the telecommunications infrastructure to create a physical connection with a remote access server, which is attached to a Local Area Network LAN.
The physical or logical connection between the remote access server and the remote access client is made possible through dial-up equipment.
Dial-up remote access is considered a private communication portal. The nature of the dial-up equipment and WAN infrastructure varies, depending on the type of connection. There are several telecommunications technologies can make up the WAN infrastructure used in dial-up remote access.
The remote access software dials in directly to the network server. Dial-up access is still prevalent in many companies.
A virtual private network VPN is a communications network linked through another network. A VPN connection has a topology more complex than point-to-point. The distinguishing characteristic of VPN is that they overlay other networks to provide connectivity that is useful to a user community.
With virtual private network remote access, a VPN client uses an IP internetwork to create a virtual point-to-point connection with a remote access server acting as the VPN server.
One common application for a VPN is secure communications through a public network. VPN access has increased in recent years because connection costs between remote workforces and global enterprise locations continue to increase. Companies have begun taking advantage of the Internet as a remote access infrastructure by implementing VPNs.
When choosing between dial-up and VPN for a remote access solution the following factors were considered: One of the best arguments for VPN is that you get more for less. T1 lines can be provisioned to provide both voice and data service, reducing the overall cost for the T1 line.
This includes customer premise equipment, software updates, equipment service and support, and management of the network. Security Security on networks is required due to increased remote access and also an increase in the type of hardware used to access the network.
Companies that are concerned about their private information being accessed through the network connection are implementing VPNs. VPNs have gained favor as a security solution because they are standards based and relatively inexpensive.
A major security issue is that network connection ports can be exploited by various threats, including viruses, hackers and spyware. After proper authentication, they can connect to other network functions. This provides a secure network connection. VPNs need to be designed and operated with well-thought-out security policies.
Organizations using them must have clear security rules supported by management.T1 line speed is consistent and constant. A T1 line can carry 24 voice channels for telephone calls or digital data at a rate of Mbps, and with usage of compression, carried channels double to Regulatory Charges and Surcharges.
Charges are $ for each dedicated service, and $19 per Billing Telephone Number (BTN) for Switched Services. Excessive Call Attempts Surcharge. regardless of whether the line is used for voice or data traffic. 3 T1 links carry both voice and data on a single T1 Basics digital communications link.
By reducing the number of lines needed to carry information, the task of manag-. T1 is a high speed digital network ( mbps) developed by AT&T in and implemented in the early 's to support long-haul pulse-code modulation (PCM) voice transmission.
The primary innovation of T1 was to introduce "digitized" voice and to create a network fully capable of digitally representing what was up until then, a fully analog telephone system.
A T1 line is a dedicated transmission connection between a service provider and client. It uses an advanced telephone line to carry more data than a traditional standard analog line that carries a single channel of data at 64 Kbps.
As networks expanded and applications required speedier transmission rates, time-division multiplexing (TDM) technologies stepped in to provide cheaper and faster data transfers on large-bandwidth circuits, often making it cheaper to lease a dedicated T1 line than to run several low-speed lines.
