ATM Subsystem

ATM is a cell-switching and multiplexing technology that combines the benefits of

circuit switching (constant transmission delay and guaranteed capacity) with those of

packet switching (flexibility and intermittent traffic). The ATM subsystem is the HP

implementation of the ATM technology. The ATM subsystem supports the ATM User-

Network Interface (UNI) Specification Version 3.0 over a 155 Mbps SONET STS-3c

connection.

For more information on configuring and managing the ATM subsystem, see the ATM

Configuration and Management Manual.

SLSA Subsystem

The SLSA subsystem provides access to parallel LAN and WAN I/O. The SLSA

subsystem provides access to ServerNet adapters, multifunction I/O-board Ethernet

adapters, the ServerNet wide area network (SWAN) concentrator, and Expand-over-

ATM line handlers.

For more information on the SLSA subsystem, see the LAN Configuration and

Management Manual.

ATM 3 ServerNet Adapter (ATM3SA)

The ATM3SA provides one bidirectional full-duplex ATM 0C3 port for connection to the

UNI. The UNI is an interface point between ATM end users and a private ATM switch,

or between a private ATM switch and the public carrier ATM network. The UNI

interface is defined by standards adopted by the ATM Forum.

For more information on the ATM3SA, see the ATM Configuration and Management

Manual.
