AR300 Series Routers
The AR300 Series comprises a family of fixed function routers. Models are
distinguished by the type of WAN port on the base CPU card and the number
of analogue voice ports supported (Tabl e3 on page 18).
AR300 Series routers have the following standard interfaces:
■
0, 1, or 2 WAN ports. All models except the AT-AR320 have an ISDN Basic
Rate S/T or U port and/or a synchronous port, or a G.703/Primary Rate
ISDN port. The AT-AR320 has no WAN ports.
■
1 or 2 asynchronous ports with DB9 connectors. The AT-AR300L(S),
AT-AR300(S) and AT-AR310(S) have female connectors. All other models
have male connectors.
■
1 Ethernet LAN 10BASE-T port (except the AT-AR320 and AT-AR330 ,
which have two Ethernet LAN 10BASE-T ports).
■
Voice ports, on the AT-AR300(S) and AT-AR310(S).
In addition, AR300 Series routers have a dedicated MAC slot which can
accommodate any of the following MACs:
■
AT-AR010 EMAC, Encryption MAC.
■
AT-AR011 ECMAC Compression/Encryption MAC
■
AT-AR011 V2 ECMAC Compression/Encryption MAC.
■
AT-AR012 CMAC, Compression MAC.
