ADTRAN 1200262L1 ATLAS 800/800 PLUS IMUX-56/64 MODULE

The IMUX-56/64 Module combines multiple ISDN B-channels using the BONDING Mode 1 protocol to support high bandwidth ISDN applications such as dial backup of Frame Relay or dedicated circuits. The BONDING capacity of the module is 60 DS0s or ISDN B-channels, which can be allocated according to the user's needs. For example, an ATLAS system can be configured toCONNECT eight B-channels USING BONDING as a dial backup link to a remote 512 kbps ISDN device, such as the ISU 512. Similarly, the module might be configured to implement two sessions at 512 kbps, 1 at 384 kbps, and 6 at 128 kbps. Table 1 shows how many sessions can be supported at typical BONDING rates.
