5- Calling Line Identification
Presentation (CLIP):
6-Caller ID (caller identification, CID), or calling
line identification presentation (CLIP):
Caller ID is a telephone service, available in analog and digital phone
systems and most voiceover Internet Protocol (VoIP) applications, that
transmits a caller's number to the called party's telephone equipment
during the ringing signal, or when the call is being set up but before the
call is answered. Where available, caller ID can also provide a name
associated with the calling telephone number.
•Caller ID may be used to track down or limit the impact of telemarketers,
prank calls, and other annoyances. However, it can also impede
communication by enabling users to become evasive. The concept
behind caller ID is the value of informed consent; however, it also
poses problems for personal privacy.
Subscriber trunk dialing (STD) is a facility that enables
users to make trunk(long distance) calls without the
assistance of an operator. The facility is prevalent in Indian
telecom companies, including BSNL. If you want to prevent people
from making long distance calls on your BSNL phone, you should
consider locking STD.
In this way, someone can make long distance calls on your
phone only after entering a secret code.
For 100% protection against improper use, you can lock
your telephone electronically. Here, you only know the secret
code. You can lock/allow Local, STD or ISD calls in many way
viz. all calls allowed, only local calls allowed, only STD & Local
calls allowed, all outgoing calls barred etc.
Register Secret Code
Suppose you want to make 5555 your secret code. Follow this procedure to
register this:
Dial 123 5555 5555 then wait for the acceptance tone then disconnect. Your
code is registered.
Change secret code
Suppose you want to change current code 5555 to 4444 then
Dial 123 5555 4444 then wait for the acceptance tone then disconnect. Your
new code(4444) is registered.

8- Call Conferencing :
A conference call is a telephone call in which the calling party wishes to have more
than one called party listens in to the audio portion of the call. The conference calls
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. It
is sometimes called ATC (Audio Tele-Conference).
Conference call can be designed so that the calling party calls
the other participants and adds them to the call; however,
participants are usually able to call into the
conference call themselves by dialing a telephone number that
connects to a "conference bridge" (a specialized type of
equipment that links telephone lines).
Companies commonly use a specialized service provider who
maintains the conference bridge, or who provides the phone
numbers and PIN codes that participants dial to access the
meeting or conference call.
An ISDN subscriber can establish two simultaneous independent calls
(except when the terminal equipment is such that it occupies two 'B'
channels for one call itself like in video conferencing etc.) on existing
pair of wires of the telephone line (Basic rate ISDN) where as only one
call is possible at present on the analog line/telephone connection. The
two simultaneous calls in ISDN can be of any type like speech, data,
image etc. ISDN also supports a whole new set of additional facilities,
called Supplementary Services.

characteristics of a transmission medium and its ability to transport
multiple signals and traffic types simultaneously. The medium can
be coax, optical fiber, twisted pair or wireless

cable that is used for connecting telephone). This provides high speed
internet connectivity.
