Figure 1-2. Frame Relay Circuit

The Frame Relay/Router upgrade option adds the capability for the ATLAS series of Integrated Access Devices to act as a voice/data FRAD, a frame relay switch, and an IP router in addition to the current available bandwidth manager and switch applications.

Dedicated and Switched Connection Maps in a Single Platform

The ATLAS 800PLUS allocates dedicated bandwidth according to any of up to five unique connection maps. Any DS0 on any T1 circuit can be mapped to any other DS0 on up to 34 T1 circuits in the system. Dedicated Connection Maps can be invoked manually or implemented automatically based on the time of day and day of the week.

Additionally, the ATLAS 800PLUS can be configured to switch dialup calls to spe- cific ports or DS0s based on the number that is dialed. Switched connection map- ping is supported for dial calls placed over basic rate ISDN, primary rate ISDN, or channelized T1.

Signaling Conversion for Maximum Interoperability

The ATLAS 800PLUS can convert between Robbed Bit Signaling and ISDN

D channel signaling, giving you the flexibility to get the speed and reliability of ISDN, while preserving your investment in non-ISDN equipment. ATLAS can also convert between D4 and ESF frame formats as well as AMI and B8ZS line coding, providing interoperability with legacy equipment.
