[c-nsp] Serial-server with modem.

[MKS]

Hello List

I'm looking for a device to do out-of-band management via PSTN/ISDN to the
cisco boxes in our pops.

I'm looking for e.g. a serial-server with 2-4 serial (RS-232) ports and an
integrated modem. (well the integrated modem is optional but preferred)
Something similar to this

Do someone have any experience with this product or know of any
similar(cheaper)?

What are you using for out-of-band management?

Regards
