Small ISP w/128K Bandwidth
and DialUps on a PM2E
We will be adding another PM3, on the local net, xxx.yyy.242 and will soon
be adding more modems and another PRI line to the PM3 at the Remote Pop,
and therefore will be adding another router to replace the PM3 w24 on
line1 as the router. We have a customer that wants a subnet off the PM3
dialup at the remote location, so we will have to deal with that also.
I really need to get the dialup 64K ISDNs on to the PM3s, so we can drop
the ISDN lines that are coming in, if we need more dedicated ISDNs we
can use the PM2E for that purpose.
I would attempt it, but sure as sh*t I would hose the whole network.
Would make a good How-To, because I am sure there are very similar setups
to this all over the place.
Later
