If you want more bandwidth, you can use multiple serial interfaces card
and only use one to aggreagte the bandwith. Following are some
references
1. The NM-1E2W, 2E2W or 2E1R2W does not support the aggregated
bandwidth even each interface can support up to 2MB
2. Only NM-1FE2W, 2FE1R2W, 2FE2W, or WIC-2T support the aggregated
bandwidth
3. For WIC-1T =
Feature 1600 1700 2600 3600
Sync max speed 2.048 Mbps 2.048 Mbps 2.048 Mbps 2.048 Mbps
Async max speed 115.2 Kbps 115.2 Kbps not supported1 not supported
4. For NM-4T =
a. Four serial ports
Cisco DB-60 connectors, same cabling as 2500, 7000, NM-4A/S, NM-8A/S
Synchronous only
b.The module provides a synchronous data rate of 8 MB/sec on port 0, 4
MB/sec each on port 0 and port 2, or 2 MB on all four ports
simultaneously.
c. No bisync or half-duplex support.
