Subject: Replies - Modem Questions
----------------------------------------------------------------------------
Thanks to all (10 of 12) who sent the information we requested about
modem pools and usage. The compiled data appear below:
**What is the size of the dial-in modem pool for the use of your off-
campus students?
Akr: VTAM (IBM): 21 lines, max 2400 baud. Network terminal server:
21 lines, max 9600 baud; 10 lines, max 2400 baud.
BG: 95 modems.
Cin: 94 lines 0-2400 bps
60 lines V.32bis/V.42bis
32 lines V.32bis/V.42bis SLIP/PPP
Clv: 64 lines.
Mi: 54 14.4K bps modems, and 8 2400 bps modems.
OSU: 400 modems, with 300 of those in a SLIP service and the re-
mainder for traditional asynchronous dial-in.
Tol: 80 modems.
WS: Current size is 48. Adding ten modems within 6 weeks.
Yng: 17 lines 7171 full-screen mainframe
15 lines Xyplex terminal server (Unix)
12 lines Youngstown Freenet
**How do you fund the costs of the pool?
Akr: Funded through department of Info Svces budget. No student
fees go towards these lines. It's a problem. We can't afford
nearly enough lines, and there is no funding proportional to
the number of students serviced available to us.
BG: No fee. From Comp Svces budget.
Cin: The cost of the pools are through general funds. We don't have
a general info tech fee, although some colleges within UC have
a $100 per quarter computer lab fee.
Clv: The departmental budget covers the cost of funding the pool,
and there is no fee currently.
Mi: They are funded from the IS departmental budget.
OSU: We have funded this out of our operational budget.
Tol: Funded entirely from the Computer Services budget.
WS: Current funding structure is the Computing and Telecommunications
Dept paying for 48 monthly line charges and all of the terminal
server and modem equipment. Computer Science/Engineering pays
line charges for 10 lines. We hope to receive budget augmenta-
tion to subsidize expansion of the modem pool.
Yng: Funding is a joint effort between Telephone Svces and the
Computer Center.
**Do you block on-campus resident students from accessing the outside
modem pool?
Akr: No blockage of lines from anywhere. There is no direct connec-
tion available to residence halls yet, although there are a few
labs for them.
BG: No.
Cin: On-campus phones are blocked from 7-digit dialing of numbers
on our PBX exchanges. We do not block internal calls to the
modem pool using 5-digit dialing.
Clv: We do not block on-campus resident students from accessing the
outside modem pool.
Mi: We do not distinguish between on- or off-campus use.
OSU: No. Since student stay in our dorms is typically two quarters,
we feel that our slip service is a good alternative for them.
We don't think it makes sense for students to buy an ethernet
card for such a brief period.
Tol: No.
WS: Yes.
Yng: On-campus users can obtain an outside line and then use that
route to dial these services. We also have 10 on-campus dial-
in lines to the mainframe.
**What is the ratio of off-campus students to the number of modems?
Akr: Estimated, 24,000 off-campus students to 52 lines. (438:1).
No, we don't have enough lines.
BG: There are approximately 8,000-9,000 off-campus students (89:1).
Cin: My best guess (of off-campus students) is in the 25K to 30K
range. This would leave a ratio of about one modem for every
150 students. This ratio is too low, since the modems are
always busy, even in the early morning hours. I am in the
process of ordering 60 add'l modems and lines to add to the
pool, but this may not even be enough. Slip and PPP-type con-
nections have really driven up the demand.
Clv: 277 students per modem. This doesn't take into account the
number of faculty or staff who might also be dialing in.
Mi: We have approximately 6,000 off-campus students and 5,000 on-
campus students plus 1,000 faculty/staff attempting to use
60 modems. We figure there are 4,000-5,000 active users trying
to use these modems. (Note: The off-campus student to modem
ratio is 81:1.)
OSU: Much too low. Roughly 1 modem for each 100 students.
Tol: There are about 20,000 off-campus students, so the ratio is
250:1.
WS: 15,000 to 58. (259:1)
Yng: There are about 13,500 off-campus students, so the ratio is
between 1,125 and 794 students per line.

Ohio U replied that there is currently nobody 'in charge' of all
technology. The univ has a search underway for a CIO-type person.
Shawnee State replied, SSU does not offer dial-in access for students
to computing resources at this time. The Library does have 2 dial-
in lines to access library catalogues, but these are available to
the public and not just students.
Faculty and administration have dial-in access through 2 modem
blocks. One modem block has 4 modems and operates at 2400 baud,
while the other has only 2 modems operating at 19.2.
If you're wondering why we don't offer students dial-in options,
I might add it's because the students and univ staff are not using
the same computer systems. Academic Computing was a separate computing
dept until Nov. In the next year, I will be reviewing how we can
expand services to students and hopefully offer dial-in access some
time in the future.

Again, thanks to all of you for your time and assistance.
