[net.micro] Feedback needed on which modems handle dirty lines well

BRIAN%src.csnet@CSNET-RELAY.arpa (BRIAN T.N. STOKES -- SRC) (04/27/86)

We have a number (100+) of dialin users from all over the country who have 
recently been complaining of increased line noise when dialing in at 1200 baud. 
We are using DEC's rackmount DF03 modems in our VAX 785, and are researching a 
number of different ways of circumventing the noise problem, which is affecting 
about 30% of our remote sessions.

One avenue being investigated is the use of cleaner modems.  Interestingly 
enough, both PC Magazine and PC World surveyed 2400 baud modems in their latest 
issues.  PC Magazine's review was limited to the cosmetics of cabinetry and 
switch access, general overall sex appeal.  PC World's however, tested the 
Ceremtek, US Robotics, Hayes and Novation series with sophisticated equipment 
which duplicated three different line noise problems.  The Novation was the 
clear front runner in these tests. 

While we are investigating other solutions, such as the use of Tymnet, Telenet, 
etc., I would like to know the general experience of the net as to any of the 
above mentioned modems.  The PC World article suggests that modems can vary 
greatly in their ability to endure the low quality phone lines we are all 
suffering with these days.

Whaddya say, guys?


Thanks

InfoWorld recently ran a rave review of the AT&T 2224B modem observing
in particular its outstanding resistance to noise problems.

They also suggested that it had setup options beyond what were needed
for most micro use. These were options to configure it for central
site use but they gave no details.

List price was given as $949 (add $50 for autodial), information at
(800) 247-1212.
