 The BTS-9 is a 9-port FC-AL active hub which uses a
DB-9 connector for each port allowing native connection to copper cabling.
The BTS-9 also supports optics on all 9 ports through the use of external
DB-9 to optics Media Interface Adapters (MIAs). MIAs are hot-pluggable and
field upgradable, providing hub users with maximum flexibility in mixing
copper and optical connections in their Fibre-Channel systems. Power is
automatically supplied on a per port basis to each connected MIA.
The Reflex feature, an intelligent
port detection and bypass capability, dynamically reconfigures the
arbitrated loop network to preserve communication between all operating
devices. Using Reflex, the BTS-9 manages movement of nodes on and off the
network, constantly monitoring nodes for failure, cable disconnection or
network reconfiguration. Non-operating nodes are automatically bypassed,
newly communicating nodes are automatically entered onto the loop. All loop
reconfiguration is handled by the BTS-9 without disrupting communication
on the remainder of the network. In the absence of the BTS-9, the physical
loop would need to be re-cabled on the addition or removal of a node,
bringing the network down and disrupting communications.
The BTS-9 can be cascaded to other
FC-AL hubs for the expansion of the loop. Port expansion is supported to
the FC-AL limit of 126 nodes. Any port may be used for cascading.
Signal Integrity
The BTS-9 implements the most complete suite of
intelligent data detection tests to ensure the highest availability of the
Fibre-Channel Arbitrated Loop. This test suite includes:
- Valid 8B/10B Data Detection
- Oscillation Detection
- Open Cable Detection

|
These three tests allow the BTS-9 to differentiate
between valid Fibre-Channel data and erroneous data, preventing corruption
on the loop. Multiple detection circuits ensure that nodes will be bypassed
only on real line failure, allowing transient events such as bit failure
to be handled by the Fibre-Channel frame level protocol. In the event that
a node is bypassed, front panel LEDs provide convenient indication.
