ISDN PRI/T1 Solutions

PRI – Primary Rate Interface

PRI is also known as ISDN PRI or sometime T1 PRI. ISDN stands for Integrated Services Digital Network. There are two speeds of service offered: BRI or Basic Rate Interface and PRI or Primary Rate Interface. BRI is a low capacity service intended for residential and small business applications. PRI is the high capacity service carried on T1 trunk lines between telco central offices and your location.

PRI divides a T1 digital signal into 24 channels of 64 Kbps capacity per channel. 23 of these channels can be assigned as one telephone call each, the equivalent of having 23 separate telephone lines. The 24th channel is used for signaling information and special features such as caller ID and hotel / motel information services. It is a popular service for call centers which need the ANI automatic number identification or caller ID data.

T1 Solutions

T1 service can be provided as channelized or unchannelized. In the channelized T1 version, there are 24 channels. Each channel can be a telephone call. T1 gives you 24 phone lines in place of the 23 that can be accommodated with PRI. However, since there is no separate signaling channel, the signaling information that tells when a phone is on hook or off hook is carried within each channel by using or “robbing” the least significant bit. Unfortunately, channelized T1 doesn’t provide any capability for ANI or caller ID data. You need PRI service for that.

Unchannelized T1 treats all 24 T1 line channels as one big combined channel for carrying Internet service, point to point data download or VoIP broadband phone. This service is intended to be handled by digital routers, not PBX telephone systems. There are no dedicated phone channels or signaling assigned for switched telephone service.

Integrated Access

T1 (also referred to as DS1) is a standard for digital transmission over phone lines at 1.544 Mbps.
It is split into 24 channels of 64Kbps each.  T1s are often “clear channel” and all bits are available for data as well as voice.
Each 64Kbps channel (also known as a DS0) can carry data or voice traffic, and two or more channels can be combined into one higher speed data channel.  Many carriers are providing T1 solutions with the capability for voice, internet MPLS (private data) network solutions.

Long Distance/800 Service

A long distance call is a telephone call made outside a certain area, usually characterized by an area code outside of a local call area (known in the United States as a Local Access and Transport Area or LATA). Long-distance calls usually carry long-distance charges which, within certain nations, vary between phone companies and are the subject of much competition. International calls are calls made between different countries, and usually carry much higher charges

800 Service or Toll Free Service is a number that allows your customers the capability to call you from outside your local call area without incurring long distance charges.

Audio Conferencing

A conference call is a telephone call in which the calling party wishes to have more than one party participate in to the audio portion of the call. The conference call may be designed to allow the called party to participate during the call, or the call may be set up so that the called party merely listens into the call and cannot speak

They worked miracles for us…

“I would highly recommend Walnut Telecom Group to anyone who is looking for a phone partner. Chris was instrumental in getting a phone hook-up in a complicated environment within a very limited window of time. They say it pays to know someone in the business and I am so glad that I know Chris. He was able to accomplish things that I could never have been able to do on my own. Chris was responsive to my crazy anxiety attacks regarding securing the necessary internet services. He would call and email me back at all hours. Next time, I will believe it when Chris says not to worry. Bottom-line: They worked miracles for us and I will definitely call them with my next installation. Thanks, Chris. “

Bobbie Bolinger, Hacienda Colorado/Elways Steak Restaurant

Consistently brings the best solution…

"I have worked with Chris for the past six years and he has served as our telecom partner and coordinated many significant changes for this organization over those years.  He helped us managed and reduce multiple vendor contracts as well as bring better choices for new or replacement services from the marketplace.  On several occasions, Chris has also made sure that our new services were installed and in good working order; he has run interference for us with slow or non-responsive vendors and made sure that we were getting the support we needed from our telecom vendors.  It is has been a pleasure to work with Chris and I truly value his depth of industry knowledge and commitment to consistently bring the best solution that he can to our organization."

The only resource I need…

“As an IT consultant, I am focused on worrying about how my clients’ data network services are working, and cannot always keep abreast of current telecom trends and offerings. When I have a client who needs to introduce, add or change telecom services, I will always call Chris immediately–with no exceptions! Over the years, I have come to the conclusion that he is the only resource I need when it comes to finding the right telecom services at the right price for my clients. As a result, I no longer waste my, or my clients’, time trying to find the right telecom solutions, and I am able to deliver even greater value because of his services. He provides some of the best after-the-install support and provider support access I have experienced in the industry. Since adopting Walnut Telecom Group as my only go-to telecom consultant, my client satisfaction surveys have improved considerably.”

Ryan Ploger, IT Consultant

A pleasure to work with…

“I have known Chris for years and worked with him in several companies I have worked at. In our latest capacities I have recommended Chris to clients without hesitation – He is honest and delivers both product and services to my clients without question. I value his involvement and I increase my own standing with my clients when I recommend him. It is a pleasure to work with Chris and my pleasure to let others know they are in good company when using Chris' services.”
