- [we have 1 MP/16 in a modem pool....]
-
- it's a single black box with 8 or 16 built-in ACUs; 8/16 serial ports
- (RJ-45), 8/16 RJ-11 phone jacks. there are either 1 or 2 banks of DIP
- switches for setting defaults for each bank (each control a bank of 8);
- no other user-accessible components on the box. they're essentially
- equivalent to couriers including all the available settings and options
- (flash upgradable, templates, DIP switch settings, etc...), although
- each "modem" can have a separate configuration. it does seem to
- support just about everything: ITU-T V.34, V.FC, V.32 terbo, V.32 bis,
- V.32, V.42, V.42 bis, MNP, and all the lower speed forms. also includes
- V.54 (remote loopback testing).

-
- no, there's no management beyond what you can get through the
- serial port.
-

-
- we have had an MP/16 in operation for a few months and have been
- working flawlessly (except recently where it's reporting "critical
- failure" on many of the lines as times; i suspect it's going tits-up
- and will need to be exchanged; whole box). minus that, i/we have been
- extremely pleased with them and will probably add more to our pool.
-

- >>expecting to need much support.
-
- unsure about support. i sent my "critical failure" query ("what does
- it mean ?") a few days ago to their e-mail line. i've been told it's
- been assigned but because of the "holiday season" [???], it may take a
- while. i believe new images and whatnot are freely available via
- web/ftp (but haven't looked into the 36.6k image yet)
-
- one thing we ran into was that we had to get a special (octopus) cable
- to run it into our cisco 2511 and had a hell of a time getting through to
- anyone knowledgable at USR.
-
- given what i've seen so far, support sux. but once it's up and running
- (minus possible failures), you probably won't need to bug them.
-
- >>How to these compare to their other Total Control systems?
-
- the MP/16 is our only product. we paid around $7k 8 months ago (this
- may have included an educational discount). the uber-total control w/
- T1 (and massively configurable) i'm told runs around $25k.
-

- >>Most rack mount systems i've seen cost a fortune and do 15 things we
- >>don't need.
-
- this is pretty much a no-frills, just-play-modem box (for us it was
- about $450/pop). we'll also be bringing up a set of individual couriers
- (for another dept), which will be interesting to see how the two compare
- as far as maintenance.
