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 _ 800
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
invoked manually or implemented automatically based on the time of day and
day of the week.
Additionally, the ATLAS _ 800
PLUS
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 _ 800
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.
