(Hi Cap) the easy definition is it is a circuit that goes to a Telephone Company or Internet
that can handle a larger volume of traffic than a regular phone line.

A typical T-1 circuit can be broken into 24 individual voice channels or configured as a full
1.544 megabits per second data channel
to the Internet or another
Computer System


PRI – Primary Rate Interface The easy answer is a circuit that carries voice and caller
id information
into a digital phone system.

A Primary Rate Interface typically has 23 voice channels and a data (D) channel.  By using a PRI
calls can be processed faster and more efficiently by a telephone processor.

Keating Communications can tell you if this will benefit your business.  Our Company can provide you with
the answer if your system has the capability to use a PRI Circuit.

A typical installation will require your phone switch to have the capability to use a PRI Circuit and transform
the calls from digital to voice, process data for caller id functions etc.

Dynamic T-1 the best answer is a T-1 for Internet access that only
uses channels for voice when a call is in progress

Most carriers now use Dynamic T-1 service to send all calls as VOIP
(Voice Over Internet Protocol) calls
, which allows full utilization of the T-1
as an Internet access circuit when there are no calls in progress. 
The carrier can deliver the voice portion as a PRI, Super trunk, or analog lines
by installing an access device to transform the data to voice for your phone

This allows you to use your current phone switch without the expense of
VOIP telephones or VOIP telephone switches.

At Keating Communications we can help you decide which system can help your communications needs.


        Bonded T-1   the definition of a Bonded T-1 is a combination of two or more
        T-1 circuits into a single large circuit
which allows for higher speed and larger usage.  At the
customer premise a special type of router will be provided to allow the customer to use
both T-1 circuits at the same time

  (T 3) the easy answer is it is a Data Channel that is capable of carrying 28 T-1 circuits on a
single data circuit.
A DS 3 circuit is a data circuit that carries 44.76 mbps and is commonly referred to as a 45 Meg circuit.
circuits require two Coax cables, one to transmit and the other to receive. Keating Communications
can place these cables for you, call for a free quote  

DIA (Direct Internet Access) this is easy to answer. DIA is it is an
 internet access circuit that is always on
.   These circuits can be provided on a DSL, T-1,
and Cable DSL, DS3, or satellite circuit
. Any of these circuits will provide a direct access
to the Internet.

 VOIP (Voice over Internet Protocol)   the easy definition is a way to transmit telephone calls over the internet

Voice over Internet Protocol changes voice to data and sends packets over the internet and at the other end changes them back to analog voice

The mistake people make is thinking all internet connections will work well with VOIP.  The problem is that each call uses between 60 to 80 kilobits and many DSL and Factional T-1 circuits do not have enough bandwidth to carry the voice transmission
