Figure 4-13 IMATM Used with Remote MGX 8220

T1, E1 or T3
Up to eight T1 or E1 links in the inverse multiplexed channel can be configured depending upon the
bandwidth desired. Bandwidth of T1 links range from 1.54 Mbps for one link to 12.35 Mbps for all eight
links. Bandwidth of E1 links range from 2 Mbps for one link to 16 Mbps for all eight links. The BNI
port bandwidth is configured to match the IMATM bandwidth.
Additional links can be provisioned to provide some protection against link failure. To achieve this, the
BNI trunk should be programmed to have a statistical reserve equal to the bandwidth of the extra links.
In the event of a link failure, a minor alarm occurs but no rerouting. Without this feature, a single link
failure will cause a major alarm and all connections will be rerouted over another trunk.

IMATM LED Indicators

The IMATM LED indicators are described in Table 4-3. All LED indicators are located on the faceplate
