AR700 Series Routers
All AR700 Series routers include Ethernet ports, asynchronous ports, and PIC
bays; the AR750S, AR750S-DP and AR770S also have switch ports. PIC bays
add expansion flexibility by allowing the installation of PIC cards, which are
available with additional interfaces, such as ISDN (PRI E1/T1, BRI S/T),
synchronous, or asynchronous ports. The AT-AR745 routers also have an
expansion bay to accommodate a Network Service Module (NSM), which either
directly provides further interfaces, or provides multiple slots where additional
PIC interfaces can be added.
The AR725 and AR745 routers have a dedicated PCI Accelerator Card (PAC)
slot that accommodates special purpose PAC coprocessor cards. PAC cards
provide additional functionality or performance, such as compression or
encryption, through a high performance PCI bus, but do not add extra
interfaces. The AR750S and the AR750S-DP have built-in high performance
encryption processing.
AR700 Series models are distinguished by the number and types of ports and
presence or absence of an NSM bay and/or PCI Accelerator Card (PAC) slot.
