reverse telnet over PSTN

kjbarrass · ‎09-07-2007

Hi

We have a central Cisco router which has a a ISDN/Mica Modem module in it connected to an ISDN line.

Does anyone know if it is possible if logged onto the central router via telnet to reverse telnet to a out-of-band device over PSTN. the out of band device is a device sat on the PSTN network that requires a user to normaly dial into it using hyperterm.

Im sorry this is very vague if you require more info please let me know.

I have misunderstood your email I am thinking. To configure a line to require CTS, use the "modem cts-required" subcommand. The following link further explains this configuration option. http://www.cisco.com/univercd/cc/td/doc/product/software/ssr83/tsc_r/54004.htm#xtocid9162105

The following URL will give you the information about Reverse Telnet to a Router Followed by a Dial over a PSTN Connection

Hi, thankyou for the reply. Its hard to explain what im trying to do. at remote sites we have out of band managment devices that have modems in them. normaly we use a computer and hyperterminal to dial into these using a phone line. What im trying to do is acheive the same but use a router rather than a PC to dial into the out of band managment devices. the out of band devices are not IP/PPP enabled devices. hope this helps.
