IP Telephony is the common term used for the IP-based networks that build,
provide and access voice, data and other
forms of telephonic communications and to replace the telecommunications’ infrastructure of
Circuit Switched Public Data
Networks. It provides communication over an IP based network, or Internet Service Provider or
directly form a
telecommunications Service provider.
TDM
Time Division Multiplexing is the process of dividing signals into many
segments by transmitting data streams over a
common channel. These signals are divided into equal time slots having very short duration.
After multiplexing, they are
reassembled at the receiving end, into their original form. TDM is flexible and can send many
signals in a single long
distance line with proper performance by adjusting time intervals and making best use of the
available bandwidth.
IPT
IP Telephony uses Internet Protocols to communicate over the internet. IPT
lowers the operational costs and increases
productivity. It provides a consistent, reliable and highly secure communicational service to
the users.
