BRI - This release adds support for the V3 hardware revision of the AT-AR021
BRI-S/T Port Interface Card (PIC). The AT-AR021 V3 hardware revision is a
plug-in replacement for the V2 hardware revision, which is no longer
available. The AR021v3 has the same feature set and command set as the
AR021v2, except that it does not support NT mode operation. Existing
configurations for normal TE mode operation will run unchanged on the
AR021v3.
The AR021v3 PIC can be installed in the following expansion bays:
■ PIC bays on the AR415S, AR440S, AR441S, AR442S, AR725, AR745,
AR750S, AR750S-DP, and AR770S routers
■ AT-AR040 NSM installed in the AR745 router, Rapier 16fi, Rapier 24i,
and Rapier 48w switches.
