TELECOM 247

I have just inherited four sites linked via BT Kilostream circuits.

Theres some old Cray DCX 818 and BT multiplexers connected to the
Kilostream NTEs and the end result is that the remote sites have async
terminal access to a central computer system.

Although everything works OK, the muxes are temperamental - they are
maintained by BT but are often in need of attention.

Not having worked with such circuits for many years, I would like to
open up the following questions to the floor...

What modern kit could replace the muxes?

What are the pros and cons of replacing the Kilostream circuits with
broadband? I would expect Kilostream to actually be more reliable but
obviously slower.

Can you get an ADSL async stat mux?

Thanks
