Network Size (per each TDM pipe)
For ring networks:
not to exceed 1022 hops
For linear networks:
not to exceed 510 hops
(actual maximums to be determined)
Spanning-Tree Networks Compatibility
Transparent to spanning-
tree frames (“BPDU” packets).
Supports new topologies:
a) As soon as new frames are received from devices.
b) After MAC address table entries age out (user-configurable time). Unicast
traffic is then broadcast.
Multicast Networks Compatibility
Transparent to Multicast Frames (multicast frames are broadcast).
Transparent to Multicast Routing Frames (transports IGMP and GARP frames).
Does not “sniff” IGMP frames (debatable utility for multi-camera multicast
networks).
MAC Security
Secured mode of operation (MAC
learning disabled, no MAC aging,
unknown MACs blocked):
Yes, user-configurable per port
Port disable on disconnect:
Yes, optional
Intruder detection:
Yes, optional for Secured ports
Unit Security
High Security mode (only VistaNET
administrators are allowed to configure
non-SONET path related settings)
Yes, optional
