On my local side, I have Cisco 3640 with one PRI port, 30 mica modems configured. On the remote side, there is AS5300 device but the PRI interfaces are used for some other purposes. Just to manage that device from my central office, I tried to connect 3640 with the remote side over the AUX port of AS5300.
On AS5300, I have created Async interfaces and configured necassary (hopefully) items under the aux 0 interface. I did not use dialer interface commands. Modem call was initiated by central 3640 router. However, I was not succeeded in connection. Remote AS5300 successfully identifies the connected modem but there is nothing about connectivity. "Line is up, but line protocol is down" is the answer of "show int ser x/y" command on 3640.
Am I doing right things, or should I use dialer interfaces? What is the proper way of doing such a connection?
I assume that you want to manage as5300 from local office where you have 3640 with mica modem and PRI line.
The easiest way to do so is by reverse telnetting into one of the mica modems on the 3640 & dialing using ATDT to the remote end as5300. That way you can use mica modems to dialout on PRI line to connect to aux port of AS5300 to setup ecex session. To reverse telnet into mica:
First you need to find any up/up interface..Like loopback or ethernet interface..
telnet (2000+line number corresponding to a modem) So to dialout using modem # 10, you need to issue
telnet 126.96.36.199 2010
After that type "AT", should get an "OK", then lets say you want to dial 14081234567 then you need to issue
On the as5300, under the line aux 0 need the following:
