Im currently running a 3660 router with 2 module slot occupied by 2 4 serial ports. I also am employing 2 2511 for dialup. I want to use the 2511 to another site and use the 3660 for my dialup as well. We currently have 4 empty slots.
I need help in choosing the right modules to buy. If I buy a 32 digital modem module, do I also need to buy a 32 port Asynchronous Network Module ? Aconfiguration example will be very much appreciated
Please I need advice and help.
Below is the current configuration of my 2511 routerSuvaDialUpRouter02#sho conf
Using 2172 out of 32762 bytes
service timestamps debug uptime
service timestamps log uptime
aaa authentication login use-radius radius local
aaa authentication ppp use-radius if-needed radius local
aaa authorization exec radius local if-authenticated
aaa authorization network radius local if-authenticated
You need to buy 32 Digital module (NM-32DM) only if you have a digital line Channelized T1/E1 coming in the 3660 over which 2511 will dialin..But if you just have analog POTS line coming in at 3660, you just need a NM-32AM to terminate the analog calls from 2511..
config will be nearly the same as you have on 2511 right now (shown above) with just more lines (line 1 32) and "group-range 1-32" under interface group-async 1..
Thanks for the info. One more question. Does this mean that I dont buy the 32-port Asynchronous Network Module ? What i want is to totally isolate the 2511 that we currently use for dialup. I want my user to dial into the 3660 router now. The 2511 will be deployed to two of our main sites where users just dial in to that 2511.
Thanks for all the info. Im starting to get to understand it very well. I have done some quiries to our Telco provider and the cost of a T1/E1 is quiete expensive. What modules will I need if I just utilise the current 32 analog lines Im currently using for our 2511 ? Do I need to buy a 2 by 16 Analog modems (NM-16AM) with 32 Asynchronous port (NM -32A)
