1 FREE PHONE:
Any user in the telephone network can call the free phone subscriber free of charge. All the charges are levied on the service subscriber (one who subscribes for the service and receives the calls). For the calling users the calls are free. The service subscriber is allotted a free phone service no. (3 to 5 digits). For the same free phone no. the subs. can have many destination nos. depending on the day of the week or time of the day.
2 VIRTUAL PRIVATE NETWORK
The Virtual Private Network (VPN) service provides the VPN customer all the features of a private network by using the Public Switched Telephone Network (PSTN) resources.
It allows the VPN customers (with significant long distance traffic between corporate sites) to configure and use switched carrier circuits as if they were dedicated private lines. A VPN customer can define his own private numbering plan and class of service restrictions across closed user groups. VPN service in this sense can be compared with a Centrex or a PBX.
The charges for a VPN call can be flexible. The charges can be levied to a common “Charge number”. In this way, a company’s traveling salesman can make STD calls while the charges are levied to the organization’s common charge number.
3 ACCOUNT CARD CALLING (ACC)
This service allows the virtual subscribers or users to make calls from any normal telephone to any desired destination nos. and have the cost of these calls accredited to the account specified by the ACC no. which does not refer either to the calling line or to the called line.
All ACC calls are preceded by the access code i.e. 160433. After dialling the access code the user is prompted to enter the Account card no. and then the authentication code. Once authentication is validated the user is prompted to dial his choice. Now the user can make calls provided there is some balance in the account.
4 VIRTUAL CARD CALLING (VCC)
The service allows a user to make calls from any telephone from any place in India where ever SSP connectivity is available & the access code is opened in the local exchange. The user invokes the service by dialling the access code and then the card number. After authentication by SSP, the user is allowed to dial any destination as per the type of the card. The call charges are debited to the users account and no charges are levied to the calling telephone no. The advantage in this service is that the user need not be a telephone subscriber and need not carry cash for making calls.
5 PREMIUM RATE
The premium service allows service subscribers to offer services like forecast, fortune, share market, &job consultation, etc. These service subscribers are allotted with a premium rate no. of 3 to 5 digits by the service provider. When the user makes calls to this PRM no. the complete cost of the call plus some extra cost( as decided by the service provider) is accredited to the account of the calling user.
6 TELEVOTING
This service allows the service subscriber to survey public opinion using telephone network. Persons wishing to respond to an opinion poll can call the advertised Televoting no. to register their votes. For this, the service provider can temporarily allocate a televoting no. with the last two digits called the “choice digits” as variable. It is required to predetermine the choices and then make the call. Most of the calls shall be routed to Announcement which acknowledges the call. Facility also exists to route selected calls to a public number. After voting is ceased the service subscriber will be provided with the results.
This service can be of either Called charged or Calling charged. For a televoting call if the call charges are borne by the service subscriber then it is Televoting (Called charged) and the access code is 1603xxxx For a televoting call if the call charges are borne by the users themselves the it is Televoting (Calling charged) and the access code is 1902xxxx.
7 UNIVERSAL ACCESS NUMBER
This service enables a subscriber to publish a national no. and have the incoming call routed to different destinations based on various criteria such as the geographical location of the caller, the time, day, or date on which the call is made. This is a unique no. which is allotted to the service subscriber on subscription to the UAN service. This is the no. that shall be dialled by the users to contact the service subscriber. There are two types of UAN, UAN (Local) & UAN(National).
8 CHANGE IN NUMBER (CIN)
CIN service provides a substitute to the specialized change number enquiry systems presently used by the telecom administrations. This service is specially useful for network operator who have to advertise the new numbers whenever there is a large scale change in the directory numbers due to exchange code modification.
This service is more useful than the conventional one. If the new number of the called party is not known to the calling party, he dials a special code, e.g.1606 followed by the old number. His call will be routed automatically to the new number which is not done in conventional implementation. At present this CIN is not implemented.
