LAN to LAN dial solution

[sbrillus () blueyonder co uk]

Can anyone suggest, other than using Cisco's a brand of UK-compliant boxes
that effectively will perform a PSTN dial up function, so that when the
two boxes are connected, the LAN's are effectively bridged together

Basically what we want to be able to do is connect a PC on a LAN, so that
at will, a number can be dialed and you can then telnet to the far end

Thanks
