To me, a trunk usually refers to a single channel of service (and we can drill down further to hairsplit between a line and a trunk).
A Supertrunk is indeed carried over a DS1 facility. One of the key differences is that all lines will ID to the same BTN or LDN. In other words, whether you call out on the 7th channel or the 23rd channel, the called party will always receive the same telephone number.
That's what the "TER" thing refers to. Back in the day I don't think they called it a Supertrunk...but maybe they did. Anyway, it was always identified by a main telephone number followed by TER 1, TER 2, TER 3, etc. "TER" was short for TERMINATION point, or something like that.
So "213-555-1212 TER 5" referred to said circuit, fifth channel.

These are delivered via standard POTS lines, not DS1. The first line is the actual WTN, the terminal number starts after that. So TER 1 is really the second line. To report trouble on the fifth line, you need to reference TER 4.

And it helps if Term 5 is the same at both ends. After 10 years or so of cable damage, reroutes, replacements, etc, there are usually 2 or more mis-labeled! Been there, Seen that!

I think we're still missing a basic definition here...the OP asked to define both terms, Trunk and Supertrunk.
First, a trunk is a connection between two pieces of switching equipment, as opposed to a "Line" which is a connection between a switch and a piece of terminal equipment (telephone, RAN, answering device, etc.) A trunk can be digital or analog, copper or fiber.
The only times I have seen the term "Supertrunk" used, it has referred to a T1 (Not PRI) with AMI framing. I've seen them in AT&T literature, as well as in sales proposals from (now defunct, I think) US-LEC.

Thank you all...I appreciate your input!
Does anyone know how (short of going to work for a telco company) how I can self-study and learn more about the topic of telcom??? Are there any decent (and accurate) books on the subject???
