Port Interface Cards (PICs)
PICs provide a cost effective and flexible mechanism for adding new or
additional WAN network interfaces to Rapier switches. By adding or changing
PICs, the switch’s network interface capabilities can be upgraded without
replacing the switch itself. A PIC can provide additional network interfaces, or
can be replaced with a different PIC to provide alternative interface types.
The following PICs are supported on Rapier switches:
■ AT-AR020 PRI E1/T1
■ AT-AR021 (S) BRI S/T
■ AT-AR021 (U) BRI U
■ AT-AR023 SYN
■ AT-AR024 ASYN4
■ AT-AR027 VoIP-FXS
The AT-AR022 ETH PIC and AT-AR026 4ETH PIC are not supported on the
Rapier switch because performance of these interfaces is likely to be reduced
and packet loss may occur.
The AT-AR040 and AT-AR040-B NSM must be installed before PICs can be
used with a Rapier switch. Table 15 shows which PICs are appropriate for
compatible models of Rapier switch for the AT-AR040 NSM. Table 16 shows
which PICs are appropriate for compatible models of Rapier switch for the
AT-AR040-B NSM.
The AT-AR021(S) V3 hardware revision, identified by the label “AR021v3” on
the board, requires a switch running AlliedWare

Operating System version
2.9.1-13 or later.
