They do not "squeeze" bandwidth. They use concentration. Some of the
Digital Loop Carrier systems that use this are Nortel DMS Urbans and
Rurals and SLC-96 Mode 2.
To the best of my knowledge, I have never seen or heard of a device
putting more than one voice call on a single DS0. I know for certain
that it is NEVER done in a SLC-96.
