The switch is a 5ESS.  I don't know the generic.  You can get the
scoop on what exchanges it serves by calling 234-9901 (in area code
516).  Most of NYTel's COs can be inquired by dialing NNX-9901 (I
think).

One time when I was in Hauppauge (right next to Central Islip), and
just for fun, I tried 234-9902 (actually it may have been 582-9902).
Surprise!  I got the most bizarre tone I have ever heard on a phone
line.  I figured it was some kind of funky second dial tone, so I
dialed some more digits.  I waited, and someone came on the line and
said (in an annoyed voice):

   "You are dialing on the INTERCOM!  If you don't know what you are
    doing, PLEASE read the INSTRUCTIONS!!"

and then they hung up.  So I guess you can dial the CO intercom system
from outside the switch!  Maybe some day, I'll call up one day and
have a nice chat with some of the CO personnel.  Maybe...  :-)

Live and learn!!
