Smart-hopping 2.0 Access Point 1.4 GHz Installation Guide
A General Description of the Smart-hopping Access Point
The Patient-Worn Monitor remains connected to two Access Points for a
finite time, and thus the same data is received by these Access Points.
During this time, information for header compression and other data for
the connection is routed to the new Access Point.
One of the two Access Points then releases the radio connection. If a packet
is in progress when a handover occurs, then the packet is reassembled co-
operatively between the two Access Points.
The Information Center server receives an unbroken flow of complete IP
packets.
Technical Alerts
Each Access Point is configured to signal alert conditions that are viewed by
the PerformanceBridge Focal Point management system.
The Access Point is configured to raise alerts on error conditions. The alerts
are sent over the Smart-hopping and Ethernet LAN infrastructure to a
monitoring station or Database Server. The Access Point raises an alert if:
•
If data loss exceeds the configured threshold
•
It loses its synchronization signal
For small systems having only one Access Point and no Sync Unit, you can
configure the Access Point to suppress the loss of synchronization signal
alert.
Note that the Smart-hopping APC provides System Alerts such as loss of
synchronization, high data loss, Access Point hardware failure, and over
capacity. Also, when redundant APCs are installed, the APC provides a
System Alert for APC hardware or software failure.
Firmware Updates
Firmware on the Smart-hopping 2.0 Access Point 1.4 GHz is upgraded from
the Upgrade Tool. Refer to the service document entitled Smart-hopping
2.0 Infrastructure Installation and Service Guide for details. The Access Point
firmware image is provided on the Smart-hopping Telemetry Service Tool
CD-ROM.
Management Interfaces
The Access Point supports the full range of management interfaces via the
Smart-hopping Access Point Controller (APC). These interfaces also enable
you to view the status of the Access Point including the following
information:
•
System configuration such as firmware version
•
Connection information such as numbers of packets received and
transmitted, and number of errors
•
Waveform data information such as total number of seconds of data
sent and lost
The Access Point statistics can be read by remote devices (for example, an
IntelliVue Database Server), using the Scaleable Node Address Protocol
(SNAP).
