Like Circuit switching, TDS operates without buffers and header processing according to the pipeline forwarding principle; therefore an all optical implementation with Optical fibers and Optical Switches is possible with low cost.

In circuit switching, a route and its associated bandwidth is reserved from source to destination, making circuit switching relatively inefficient since capacity is reserved whether or not the connection is in continuous use.

In the future, this dedicated-circuit approach, known as circuit switching, seems destined to be replaced by more efficient and economical packet-switching technology on which the Internet ( and Cisco's business ) is based.

When dealing with mass market local circuit switching the Triennial Remand Order and the FCC found that ILECs would no longer have an obligation to provide CLECs unbundled access to these network elements.
46.
Packet switching, which allows many calls to share the same path, uses network capacity far more efficiently than traditional circuit switching, which opens up a dedicated circuit between callers for the duration of a call.
47.
Static TDM and other circuit switching is carried out at the physical layer in the OSI model and TCP / IP model, while statistical multiplexing is carried out at the data link layer and above.
48.
But then, in this transition from the old world architecture of circuit switching to the new world of packet switching, it is not altogether certain that Cisco plans to slug it out with Nortel and Lucent.

Only after BT changed its most senior management who were fixated on circuit switching / ISDN based on System X / Y telephone exchanges and embracing broadband / internet lock stock and barrel has this changed.
50.
The company said the decision made sense in light of the merger with MCI WorldCom, as it would be easier to meld networks with similar architectures than one based on packet switching and another on circuit switching.
