Understanding the ARN Module Locations

The ARN is designed to scale to your needs. In addition to either an Ethernet or
token ring base module, the ARN can contain an optional LAN expansion module
and up to two WAN adapter modules

The ARN is available in the following base module configurations:

ARN expansion modules provide additional Ethernet (AUI and 10BASE-T), token
ring (STP and UTP), and serial interfaces. Each ARN WAN adapter module adds
one serial, ISDN BRI, V.34 modem, T1/FT1, E1/ET1, 56/64K DSU/CSU, or X.25
PAD interface.
The Ethernet base and expansion modules can also contain an optional data
collection module (DCM). This optional DCM gathers Ethernet statistics for a
remote monitoring (RMON) utility. A subset of these statistics is gathered with a
built-in RMON function on the Ethernet10/100BASE-Tx and -Fx interfaces. See
Configuring RMON and RMON2 on BayRS Routers for information about how to
enable and use each RMON data collection implementation.
