OVERVIEW

The VHSIM2-A6DP extends the functionality of the Enterasys Networks interface module or
standalone device to include remote uplink capability. It allows remote connectivity using ATM
technology.
Two APIMs can be installed in the VHSIM2-A6DP to provide redundant ATM links from the
VHSIM2-A6DP to a switched ATM network. Enterasys Networks provides a variety of APIMs
that allow the user to select the type of configuration that best meets the network requirements. If
port redundancy is not a requirement, then only one APIM needs to be installed.
The VHSIM2-A6DP supports two types of Virtual Channels: Permanent Virtual Channels (PVCs),
and Switched Virtual Channels (SVCs), which are compliant with the ATM Forum's
User-Network-Interface (UNI 3.0, UNI 3.1 and UNI 4.0) for SVC signaling specification.
