Technical Specifications
Hardware Communications Options
The ARN is designed to scale to your needs. In addition to either an Ethernet or token ring base module, you can add an optional expansion and up to two optional adapter modules to the ARN.
The ARN is available in the following base module configurations:
•One Ethernet AUI and Ethernet
•One Token Ring interface (STP only)
The ARN supports the following expansion modules:
•One Ethernet AUI and Ethernet
•One token ring media access unit interface (STP and UTP option)
•Three serial interfaces
•One Ethernet AUI and Ethernet
•One token ring interface (STP and UTP option) and three serial interfacesinterfaces
Note: The Ethernet base and expansion modules can also contain an optional data collection module (DCM). The DCM gathers Ethernet statistics for a remote monitoring (RMON) utility. Your network administrator can refer to Configuring Remote Access for additional information about how to enable and use the DCM.
The ARN also supports up to two of the following adapter modules:
•Single serial interface
•Single ISDN BRI S/T interface
•Single ISDN BRI U interface
•Single V.34 modem interface
•Single 56/64K DSU/CSU interface
