Is there any performance issue if I have Cisco 3662 with:
1 (one ) NM-2CE1B --> 2-Port Channelized E1/ISDN-PRI Balanced Network Module
3 (three) NM-4T --> 4-Port Serial Network Modules
2 (two) NM-30DM --> 30 Port Digital Modem Network Modules
I heard that Cisco 3660 is not capable of handling 60 concurrent dial-in users and several serial connections simultaneously.
