str+="ISDN Brings the digital network to your door step. \n";
str+="ISDN brings whole new breed of applications made available by multi-channel \n";
str+="architecture, telecommuting, simultaneous voice, fax, data and inexpensive video-conferencing, \n";
str+="remote healthcare, tele-teaching, remote broadcasting and \n";
str+="high quality audio transmission collaborative CAD, CAM, ENGINEERING, \n";
str+="LAN to LAN connectivity, interactive publishing and many many more. \n";
str+="We provide two types of ISDN connections one is Basic Rate Access and the other is Primary Rate Access.\n";
str+=" |
\n";
str+="| | \n";
str+="What are the types of access? \n"
str+="Basic Rate Access(BRA): 2B+D , Primary Rate Access (PRA): 30 B+D.\n";
str+=" |
\n";
str+="| | \n";
str+="What is the difference between ISDN and normal telephone ? \n";
str+="ISDN can establish two simultaneous independent calls \n";
str+="(except when the terminal equipment is such that it occupies two B channels \n";
str+="for one call itself like in video conferencing etc.) on existing pair of wires \n";
str+="of the telephone line (Basic rate ISDN) where as only one call is possible at \n";
str+="present on the analog line /telephone connection. \n";
str+="The two simultaneous calls in ISDN can be of any type like speech, data, image etc. \n";
str+="The call setup time for a call between two ISDN subscribers is very short, \n";
str+="of the order of 1 to 2 seconds. \n";
str+="ISDN also supports a whole new set of additional facilities, called Supplementary Services.\n";
str+=" |
\n";
str+="| | \n";
str+="What is Primary Rate Access? \n";
str+="All modern Telephone, computing systems includung PBX main frame, \n";
str+="LAN and WAN, high resolution videoconferencing unit and many more can be \n";
str+="connected to though a PRI ISDN. PRI are designed to maximise use of \n";
str+="allocating dynamically to these systems for call by call and number of channels \n";
str+="required for each application. PRI provides 30 number basic channel at 64 Kbps \n";
str+="rate and the total bit rate of pri is 2Mbps and can be used in any combination for voice \n";
str+="and data. The Pri link to the customer premises is provided on the normal copper \n";
str+="cable with the line drivers at the both ends.\n";
str+=" The link can be provided by OFC if the results is there from the customer.\n";
str+=" The line driver will be provided by the department.\n";
str+=" |
\n";
str+="| | \n";
str+="What is Basic rate Access? \n";
str+="In Basic Rate access you can establish 2 wsimultaneous data,voice, \n";
str+="fax calls at 64Kbps or one data call at 128 Kbps. \n";
str+="Furthermore as many as eight seperate devices like telephone, computer,fax machine and \n";
str+="more may be connected to the same ISDN line and each can be given as many seperate \n";
str+="telephone numbers. ISDN line from the exchange to the subscriber premises is provided \n";
str+="over normal telephonecable and terminated on termination equipment called NT and \n";
str+="it is installed by the department. \n";
str+="Fixed charges and refundable deposit is Rs. 5000/- and the monthly rental of \n";
str+="Rs. 500/-, call charges Re. 1.20 per call up to 10000 calls.\n";

str+="All modern telephone, computing systems including PBX main frame , LAN and WAN, \n";
str+="high resolution videoconferencing unit and many more can be connected to though \n";
str+="a PRI ISDN. PRI are designed to maximise use of allocating dynamically to these systems \n";
str+="for call by call and number of channels required for each application. \n";
str+="PRI provides 30 number basic channel at 64 kbps rate and \n";
str+="the total bit rate of PRI is 2mbps and can be used in any combination for voice and \n";
str+="data. The PRI link to the customer premises is provided on the normal copper \n";

str+="What is ISDN PRI tariff? \n";
str+="Information can be obtained from ISDN tariff table in other information of agent \n";
str+="screen.\n";
str+=" |
\n";
str+="| | \n";
str+="Does ISDN connection require any special cable to be laid? \n";
str+="No. ISDN line works on the same copper cable upto a distance of 4 Km (approx.) \n";
str+="from the Exchange/RSU. However, ISDN lines cannot be extended over longer distances as \n";
str+="of now.\n";
str+=" |
\n";
str+="| | \n";
str+="Will ISDN connection help in getting INTERNET Access? \n";
str+="INTERNET consists of a world-wide network of Information Banks. \n";
str+="An ISDN line can be used to access the INTERNET and in that case the data transfer \n";
str+="speed would be 64kbps or more.\n";
str+=" |
\n";
str+="| | \n";
str+="Do I get dial tone by connecting an ordinary phone set on an ISDN line? \n";
str+="No.You need an NT1 to be connected first on the ISDN cable pair. \n";
str+="To hear dial tone, with the NT1 either you will have to connect an ISDN phone or,\n";
str+=" a Terminal Adapter and then through the TA an ordinary phone set.\n";
str+=" |
\n";
str+="| | \n";
str+="Will I get an electric shock by touching an ISDN line cable pair? \n";
str+="An ISDN cable pair carries 100 V DC across the leads. \n";
str+="So, you may feel a mild shock, which is however not at all fatal to any human being.\n";
str+=" |
\n";
str+="| | \n";
str+="Must the NT1 be kept always powered on? \n";
str+="Normally Yes. However, if there is no power connected to the NT1, \n";
str+="you can still make a voice call from your ISDN feature phone. \n";
str+="But you will not be able to receive calls if the NT1 is powered off.\n";
str+=" |
\n";
str+="| | \n";
str+="How an ISDN communication is disconnected? \n";
str+="Same way as for an ordinary phone call. However, ISDN communication can be \n";
str+="released by either party in communication. \n";
str+=" |
\n";
str+="| | \n";
str+="From an ISDN line can I contact a non-ISDN line? \n";
str+="You can always make a voice call. But using an ISDN data card you will be able \n";
str+="to engage in data communication only with another PC equipped with another ISDN \n";
str+="data card. Video conferencing with a non-ISDN line is, of course, out of question.\n";
str+=" |
\n";
str+="| | \n";
str+="Will calls made from different gadgets on the ISDN line be billed separately? \n";
str+="NO. Since you are, after all, using only one ISDN connection, \n";
str+="all your meter readings will be added up and billed together.\n";
str+=" |
\n";
str+="| | \n";
str+="How I will know I have been given MSN? \n";
str+="You will notice that you are able to receive calls on your ISDN feature phone \n";
str+="but can't make any outgoing call. Using the ISDN feature phone you will have \n";
str+="to program your MSN before using the facility. \n";
str+="Then you will be able to make outgoing calls confirming that MSN facility is given.\n";
str+=" |
\n";
str+="| | \n";
str+="Shall I get Dynamic Locking Facility on my ISDN line? \n";
str+="YES, only on ISDN lines from 5ESS*,AXE* & OCB* exchanges /RSUs.\n";
str+="However, as such tampering with an ISDN line is difficult as the full set of \n";
str+="Customer Premises Equipment will be required, plus one would need to know the MSN \n";
str+="programmed by the actual user. So, on the whole, security is high with ISDN lines. \n";
str+=" *please refer to the latest Telephone Directory to know the type of the exchange\n";
str+=" you are connected to.\n";
str+=" |
\n";
str+="| | \n";
str+="What information can be carried by ISDN channels? \n";
str+="Three types of information are carried in the ISDN. \n";
str+=" - User Information.
\n";
str+="- Control Information.
\n";
str+="- Network Information to subscribers.
\n";
str+=" |
\n";
str+="| | \n";
str+="What is bearer service of ISDN? \n";
str+="It is the means to convey information (speech,data and video etc.) between users \n";
str+="in real time and without alteration of the content of the message.\n";
str+=" This includes speech service with 64kbps, 8khz circiut mode, 64kbps\n";
str+=" Audio data analogous to normal PSTN service.\n";
str+=" |
\n";
str+="| | \n";
str+="What are supplementary services offered by ISDN? \n";
str+="Following are the supplementary services one can have using ISDN.\n";
str+=" - Direct dialling IN services.
\n";
str+="- Multiple subscriber's numbers.
\n";
str+="- Calling line Identification.
\n";
str+="- Call Forwarding.
\n";
str+="- Call Waiting.
\n";
str+="- Call Transfer.
\n";
str+="- Line Hunting.
\n";
str+="- Conference Call.
\n";
str+="- Closed User Group.
\n";
str+="- Advice of Charge.
\n";
str+="- User-to-User Signalling services.
