IMA Network Modules

This section provides information about the following network modules:

•

4-port T1 IMA network module (NM-4T1-IMA) (see

Figure 1

)

•

8-port T1 IMA network module (NM-8T1-IMA) (see

Figure 2

)

•

4-port E1 IMA network module (NM-4E1-IMA) (see

Figure 3

)

•

8-port E1 IMA network module (NM-8E1-IMA) (see

Figure 4

)

Each port provides 1.544 Mbps/2.048 Mbps connectivity. The IMA aggregation of multiple T1/E1 links
increases bandwidth inexpensively to allow WAN uplinks at speeds ranging up to those of a T3/E3 link.
