Hi
I've been trying to find the next compatible Network Module to replace the NM-16A/S installed on our 3845 series router. THe above module do data transmition rate of up to 128Kbps on syn/async links according to the Cisco site. What would be the next higher option to this to support serials of up to 512Kbps or even 1Mbps. Please help me with some sites.
