Each B channel carries data, voice and other services. The D-channel carries control and signaling information. The Primary Rate Interface consists of 23 B channels and one D channel at 64 kbps with a T1 line or 30 B channels and 1 D channel with an E1 line. Thus, a Primary Rate Interface user on a T1 line up to 1.544 Mbit / s service or up to 2.048 Mbit / s service on an E1 line. PRI uses the Q.931 ProtocolChannel D. Be the D channel dimensions depend on the frame format of T1 circuit. IE. Super Frame (SF) is a 56kb channel and Extended Super Frame (ESF) is a 64kb channel. Almost all U.S. airlines to offer PRI ESF format and B8ZS line coding.
In English?
The PRI voice is a line of high capacity communications designed for the business user more features at a lower cost with greater flexibility. The service is through T-1Line, and gives the user calling capacity of 23 simultaneous calls per line T-1 PRI. This service is practically a must now for any company with 20 or more users, depending on call volume.
There is a cost associated with the PRI?
Yes, this "talk" to the phone system, interface, or PRI circuit from the carrier T-1, the telephone system, a digital PRI card. Not all systems have the ability to manage PRI card, but most. PRI card prices canRange from $ 500 to upwards of $ 3,000, depending on the age of the system and who is the producer. Add the cost of installation, and is a decision to be weighed against the benefits.
What are the benefits of a PRI?
Compared to a similar environment are the many benefits of a PRI. Call research groups, DID, call tracking and reporting, CTI, for rate center DID pulsed digits, call routing, less taxes and lower costs are all chiefReason to consider Voice PRI.
1. Research groups: in a similar context, it is typical to make calls via a linear or circular hunt group for all incoming and outgoing, it can be. All incoming calls are from the top of the "group" and work your way down. Ten (10) telephone line hunt group would be an organization of 10 simultaneous calls with a single main number. Outgoing calls would then pick up the last of ten (10) lines"Group" and work their way into the main line or in the first research group. The goal is, of course, a fairly large group hunting, in order to have the incoming and outgoing, you never use all their capacity to cause. This is called "pooling in an analog line.
If you have multiple companies or departments, often separate "line pooling groups of hunters. Change in the configuration and capacity of transport by your carrier. Private lines aregenerally of "hunting groups" of the additional costs on the left. With a PRI, you can hunt all different programs on your phone. His basic rule is that you make or receive a total of 23 simultaneous calls in whatever configuration for PRI, and can be connected. Do you want to hunt 10 different groups for 10 different departments? No problem. Need a dozen private numbers? No problem. They do not even need to ask for support, since the programming of the PBX is readyLevel.
2. DID: Direct-dial numbers are the key to any organization on the rise. Direct-dial numbers are usually assigned in blocks of 20 and are developed exclusively with digital circuits work as a voice PRI. Most of the airlines, the number of DID PRI circuit to 200, but we have some rare cases, may have seen where 400-600. Do you understand?
"I have 23 channels on a PRI for simultaneous phone conversations, but can you give me 200 phone numbersNumbers? "
Yes, it's true. You can literally every associate in your organization your phone number and fax number if you want. Phone numbers run about $ 5 per month for each block of 20 years.
"Why do all these numbers?"
Considers service a priority? Then maybe you can insist your customers not to deal with auto attendants. With DID numbers, callers can bypass your auto and have their call routed directly to yourRepresentatives of the election. In a world of automation, large companies would not do without it. Your desk flooded with calls and call transfer professional? Avoid the need to route the call directly to their party.
With the growing power of desktop fax server, it is also for each employee, the fax number and have available stocks. Pdf attachments or other common format on their desktop via e-mail application. Send and receive faxesfrom the desktop without getting up, and without paying for additional dedicated fax phone lines.
3. Call Call Tracking and Reporting: Along with DID, the advanced features of the PRI phone system to monitor critical data with a can for your business. do (the software is often necessary) Do you ever wonder how many calls from sales representative? Need to know how many calls came into the customer service staff in decision-making? How many callsYou get to this last year? With the level DID call tracking and reporting, you can rationalize a number of tools for your business like never before.
4. By Rate Center DID: Some areas are changing call numbers, currency numbers, numbers of distance relay, etc. Basically, they are in neighboring markets outside the local telephone company office, the position data to be forwarded. The local phone company is oftenA monthly fee charged in addition to the line call volumes and costs associated with the mileage numbers. These costs are astronomical for companies that have a local "presence" should be in other markets. The locals in a market rather than with someone who is also local business so that the local number is essential. With a PRI, you can transform your area number to a DID and avoid mileage and postage. For the right company can mean a difference of hundreds or thousands perYear. It also opens the possibility of going into other markets and that the presence of "local".
For companies that move their local telephone company, often can not tell them that their number with them. The use of a CLEC, often you can take your number with you on a different market, not the high costs incurred by forwarding or formally linked telebranching. .
5. CTI (Computer Telephony Integration): Manychallenging tasks to integrate their voice and data infrastructure, and require the ability to calls based on database queries. With DID and caller ID of the caller, the system of PRI can look in the database that one of your representative to do with this client, and the call directly to their expansion at a time. The user can see on the computer screen like a pop, is about the state of thisCustomers change, or before you even answer the phone! This feature has limitless applications, but you must first verify that the protocol between the database system and your phone is compatible. common protocols, TAPI, TAPI 2.x, TAPI 3.x, H.323, and others.
6. Outbound Caller ID: In large companies or organizations with several companies under one roof, it is essential to have separate appearances outgoing caller ID. With PRI, you can a single companyName and number of pulses over the telephone or mobile phone group level, all using the same circuit telecommunications PRI.
If you go on every call center? Then, the same caller ID on all phones as the primary outbound caller ID for your company. All callers then calls for the forwarded calls, as scheduled. With PRI, you can maintain full control and schedule changes, as many times as needed or desired. (Programming for inspection shall be conducted by a qualifiedTechnical)
7. Cost reduction: growing businesses Voice PRI select for all the reasons above, but perhaps more important for cost reasons. If you look at a similar analog system operating capacity of the environment, but without the benefit of all of the above, the scenario would be:
23 analog lines each monthly fee: $ 30 (23 x $ 30 = $ 690)
Cost of service line by line: $ 6 (23 x 6 = $ 138)
Features Cost:? Caller IDoften extra, but comes with PRI
taxes extra? Depending on the carrier and Bell Region
The call cost:? Depending on the carrier, region, and negotiated rates
$ 690 for 23 analog lines
$ 138 for service line charges
$ 828 first feature, taxes and expenses required.
Most of the T-1 carrier, we have to do with the offer PRI for about $ 500 a month plus a fee equal to line 5 channels of the PRI. (Approximately 30) PRI Caller ID is automatically included, even if some airlinean extra charge for caller ID and name. So, for $ 530 per month, you receive all of the above characteristics, which are generally more competitive phone rates, taxes and reduced costs and a line of bottom-line difference of about $ 300 per month. So .....
When should I visit a Voice PRI?
If it costs less than digital to analog, or when the benefits outweigh the additional features are extra costs associated with the service.Additional options are now broken with the PRI circuits, integrated voice and data and voice lines, PRI-compression, high-capacity options that have made the service affordable for most businesses. Your telecommunications professional, you can decide which option is right for you.
