Integrated Access T-1s

When a business decides that its broadband needs warrant a step-up to a T-1 or ISDN PRI high speed circuit, this may represent a significant leap in cost and technology. A dynamic integrated access (IA) circuit allows a business to make the most of their high bandwidth purchase. Dynamic IA circuits not only allow users to access both voice and Internet services over the same connection efficiently and cost effectively, they also provide flexibility for the business. Integrated Access

An IA circuit delivers "always on" Internet access along with local telephone service combined with long distance service. A dynamic IA circuit manages the bandwidth to allow Internet bandwidth to rise as the demand for voice bandwidth diminishes. Correspondingly, when voice traffic grows, the bandwidth for Internet access is decreased. Voice always is given priority over data.

For example, if a business needs 12 channels of simultaneous voice capacity at the peak hour and if each voice channel requires 64 Kbps of bandwidth (some products use more and some less bandwidth), then there will be a minimum of 768 Kbps of Internet bandwidth available at all times on an IA T-1. For the time each voice channel is idle, Internet bandwidth will rise by 64 Kbps.

Dynamic IA circuits may be provided with either T-1 or ISDN PRI circuits. The ISDN PRI circuit has one less channel than a T-1 but it may be a preferred alternative if DID (Direct Inward Dialing) service or caller id service is required.

Some of the advantages of a dynamically allocated T- 1 or ISDN PRI include:

  • No wasted bandwidth - The business uses all of its T-1 all of the time.
  • Flexibility - Bandwidth fluctuates according to business needs in order to maximize the quality of connection.
  • Cost - With a dynamically allocated circuit, it is easier to cost justify a move up to T-1 or ISDN PRI.
  • Savings - Bundling of Internet access, local phone service, and long distance provides cost savings and operational savings. Some plans bundle unlimited local and/or domestic long distance calling.
  • More Savings - With integrated access you do not have to replace your telephones or phone system. Your integrated access device (IAD) connects your legacy equipment to the T-1 or ISDN PRI.

The one disadvantage of IA circuits is that three applications may be disrupted if the circuit is out of service. Fortunately, there are strategies to minimize the impact of such an outage.

King Communications can provide more information about the benefits of and strategies for implementing a dynamically allocated T-1 or ISDN PRI circuit. Give us a call at 888-776-7777 for more information.
