2 Way Lease Line Anolog Link

I am doing an As-simulation with 2 zyxel modems U336 and 2 cisco routers a 1600 series and a 2600 series. I want to have an leased anolog link between the 2 modems and the routers connect from the modem to the Respective lans. I have already configured the routers and the modems but my line protocol for both routers is down. Both modems are anolouge. Am still using default Hdlc. Any help will be highly appreciated.

Re: 2 Way Lease Line Anolog Link

If your line is analogue you need to use asynchronous interfaces on your router, by default the serial interfaces on 1600’s and 2600’s is Synchronous. Try changing it to async with the physical-layer interface sub-command.

physical-layer async

Also below is the URL for setting up async connectivity on a 1600

I have already changed the synchronous to asynchronous but that option now even turn the whole serial interface down. When i put it back to synchronous and put encp ppp it the serial goes up and down.

i have done the configuration ok but the interface keeps on reseting.

if i put encaps slip the protocol comes up but you can't ping and when you remove the modem line the line protocol is still up
