AR720 Router
The AT-AR720 router consists of a base CPU card, enclosure and power supply.
The base CPU card supports a single 10/100 autosensing Ethernet LAN port
and two asynchronous RS-232 ports. The chassis has two
Port Interface Card
(PIC) bays, which can accommodate any combination of the following PICs:
■
AT-AR020 PRI E1/T1 PIC, one Primary Rate E1/T1 port.
■
AT-AR021(S) BRI-S/T PIC, one Basic Rate ISDN S/T port.
■
AT-AR021(U) BRI-U PIC, one Basic Rate ISDN U port.
■
AT-AR022 ETH PIC, one Ethernet LAN AUI/10BASE-T port.
■
AT-AR023 SYN PIC, one Synchronous port with universal 50-way
AMPLIMITE connector.
■
AT-AR024 ASYN4 PIC, four Asynchronous ports with R-J45 connectors.
■
AT-AR026 4ETH PIC, four 10BASE-T/100BASE-TX ports with RJ-45
connectors.
In addition, the AT-AR720 router has 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.
Front and Rear Panels
The AT-AR720 router’s front and rear panels (with a PIC installed in each PIC
bay) are shown in Figure on page 38.
Table 18 on page 39 lists functions of the AT-AR720’s LEDs. Additional rear
panel LEDs may be present if PICs are installed. Functions of LEDs on PICs are
described in the
Port Interface Card Quick Install Guide
and
