61200266L1-1 ATLAS 810
PLUS
User Manual 1-3
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 re-
lay 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 810
PLUS
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 manually invoked or automatically implemented based on the
time of day and day of the week.
Additionally, the ATLAS 810
PLUS
can be configured to switch dialup calls to
specific ports or DS0s based on the number that is dialed. Switched connec-
tion mapping is supported for dialup calls placed over basic rate ISDN, pri-
mary rate ISDN, or channelized T1.
Signaling Conversion for Maximum Interoperability
The ATLAS 810
PLUS
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.
