Remote Gear Support ..

I've been poking around (thru the Black Box catalog, for example) for
equipment to help us support our remote network gear located near the
NSS to which we attach. I've had little success at finding the
right pieces. I'm wondering if any of you have implemented any of
these (listed below) solutions, and if so, where you found the
equipment to do it; then subsequent sucess/failure information.
Not in any particular order, here are the functions I'd like to be able
to perform remotely.. This is a "grandiose wish list", as it were.
* Software switchable dial-up access to serial ports
on all gear (several ports):
To Device 1
+------------->
|+------------>
|| To Device 2
Phone line +-------+ +---------+++ .
-----------------| Modem |---| Magic Box | .
+-------+ +-----------+ .
|| To Device (n-1)
|+------------>
+------------->
To Device (n)
In this scenario, I dial into the modem to the "magic box",
and give it some character code or sequence to attach me to
the specified port. I can escape back to the magic-box
and request subsequent connections without having to
redial. [Black box has one of these for 4 ports, but I hear
its not too good. Any experiences?]
* Power Cycle any of "n" pieces of remote hardware via RS232
interface and ASCII selection. Ideally, this box attaches
to one of the ports of the serial switch above, and asks me
which piece of the "n" attached pieces of hardware should be
cycled. [Black box has one of these for a single piece of
equipment. It requires a dedicated phone line, and uses
telco tones to trigger a cycle.]
* T1 line switch:
Incoming T1 +--------+ +-----------+
| |-----------------| CSU/DSU 1 |----> To router 1
-----------------| Switch | +-----------+
| |-----------------| CSU/DSU 2 |----> To router 2
+--------+ +-----------+

V
RS232 Input
Ideally, this box also attaches to one of the ports on the
n-by serial switch above, and has some sort of menu or
ASCII code line selection mechanism. Being a software guy,
I thought about wiring this up using a switch for RS232 from
Black Box.. Hardware people informed me that this wasn't
a good idea.
Again, these are the thoughts on my mind... and an "ideal wish list".
I'd appreciate hearing about any implementations or similar tools
that you have experience with.
Thanks!
