1.3 OVERVIEW
The HSIM-A6DP extends the functionality of your Cabletron Systems
interface module or standalone hub to include remote uplink capability. It
allows remote connectivity using ATM technology.
Two APIMs can be installed in the HSIM-A6DP, to provide redundant
ATM links from the HSIM to a switched ATM network. Cabletron
Systems provides a variety of APIMs that let you select the configuration
of your choice. If port redundancy is not a requirement, then only one
APIM needs to be installed.
The HSIM-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) for
SVC signaling specification.
1.4 FEATURES
ATM Port Interface Modules (APIMs)
The HSIM-A6DP supports two Cabletron Systems APIMs for ATM
connectivity and redundancy. You can easily install APIMs into the
HSIM-A6DP for the interface of your choice. The two APIMs installed
may be of any combination of physical layer cable type and bandwidth.
For example the APIM installed in slot 1 could support Twisted Pair cable
and provide 155 Mbps of bandwidth, while the APIM installed in slot 2
could support Coaxial cable and provide 45 Mbps of bandwidth.
