       I am in urgent need for information related to various HUNT
       GROUP architectures at a	phone company Central Office.
       Specific	questions I have in mind are listed below, and they
       apply to	1ESS, 5ESS, and	Cross Bar switches.

	 1.  What is the maximum capacity of a Hunt Group?

	 2.  Can a Hunt	Group be gracefully expanded ?

	 3.  What kinds	of distribution	algorithm for assigning
	     calls to lines are	used for a Hunt	Group in a Central
	     Office?

	 4.  What types	of failure modes are there? and	how would
	     each of them affect the Hunt Group	operation?

	 5.  How would a large number of lines come into a computer
	     center facility? (The number of lines I have in mind
	     is	in the thousands!) Do you use T1 or what?

       My problem is classic for anybody who wants to offer a
       dial-in computing service for a very large number of users.
       I also have other headaches such	as how to stop the hunt
       group from assigning calls to a particular Frontend machine
       if the machine fails.  If you know of a good solution or	a
       pointer to some information sources, please let me know.

       If you wonder why haven't I talked to my	friendly local
       phone company yet, that is because

	 1.  I don't know for sure where the service is	going to be
	     offered.

	 2.  Besides, I	would like to be prepared before I start
	     talking to	them.

       Thank you for your time.
