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:
I
AT-AR020 PRI E1/T1 PIC, one Primary Rate E1/T1 port.
I
AT-AR021(S) BRI-S/T PIC, one Basic Rate ISDN S/T port.
I
AT-AR021(U) BRI-U PIC, one Basic Rate ISDN U port.
I
AT-AR022 ETH PIC, one Ethernet LAN AUI/10BASE-T port.
I
AT-AR023 SYN PIC, one Synchronous port with universal 50-way
AMPLIMITE connector.
I
AT-AR024 ASYN4 PIC, four Asynchronous ports with R-J45 connectors.
I
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 MAC cards:
I
AT-AR010 EMAC, Encryption MAC card.
I
AT-AR011 ECMAC Compression/Encryption MAC card.
I
AT-AR011 V2 ECMAC, Compression/Encryption MAC card.
I
AT-AR012 CMAC, Compression MAC card.
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 37.
Table 18 on page 38 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 Port Interface Card
Hardware Reference.
