Introduction of
this form of signaling is
essential for the development of telecom networks in
any country
because of the following features:
1. Internationally standardised
by the ITU.
2. SS7 is suitable for any
transmission medium i.e., can be operated over both terrestrial
and satellite
links.
3. Even though SS7 is optimised
to work with digital SPC exchanges utilising
64 kbps
digital channels,
it is suitable for operation over analog channels.
4. SS7 is suitable for various
communication services such as telephony, text, data,
images and
video.
5. Transport mechanism is
application independent.
6.
High performance and flexibility along with a future oriented concept which meets
new requirements.
7. High reliability for message
transfer.
8. Processor friendly structure of
the messages (signal units in multiples of 8 bits).
9. SS7 networks are much faster,
efficient in the call setup and teardown process.
10. Flexible structure which accommodates
all
the technical advancement in telecommunication systems.
