Chapter 1: Overview

Introduction

The Philips IntelliVue Telemetry System (ITS) uses a cellular wireless architecture to
provide two-way communications between patient-worn transceivers and wireless
bedside patient monitors, and the IntelliVue Information Center.

Using the “Smart-hopping” wireless protocol based on Digital Enhanced Cordless
Telecommunications (DECT), the ITS provides monitoring capabilities for ambulatory
patients within a wide coverage area. The ITS transceivers (portable patient-worn
devices), wireless bedside monitors, and infrastructure operate on the 1.4 GHz US
Wireless Medical Telemetry Service (WMTS) band or on the 2.4 GHz band for
deployments outside of the USA.

The pocket-size transceiver sends patient data, and sends and receives control and
device information to and from the IntelliVue Information Center (bi-directional
communication) for subsequent monitoring, display, analysis, alarm detection,
operator alerts, data storage and permanent recording. Displays, settings,
recordings, and alarms are controlled from the IntelliVue Information Center.
Recordings can also be initiated from the patient worn-transceivers.

IntelliVue Telemetry System Infrastructure Components

You can configure the Access Point Controller to communicate with IntelliVue 1.4 or

2.4 GHz Smart-hopping Access Points (APs). IntelliVue 1.4 GHz APs can only
communicate with 1.4 GHz transceivers and monitors. Likewise, 2.4 GHz APs can
only communicate with 2.4 GHz transceivers and monitors. You cannot mix 1.4 GHz
and 2.4 GHz transceivers or monitors at a given ITS installation site.

Philips Smart-hopping technology dodges interference and locates the strongest
available signal wherever the patient roams. Dynamic wireless channel allocation
ensures best use of available wireless spectrum. When configured to operate in the

2.4 Ghz spectrum, the ITS is designed to co-exist with most 802.11 wireless
systems.

IntelliVue Telemetry System Infrastructure Components

The ITS infrastructure consists of an Ethernet LAN that can include LAN switches
and routers, and is used to interconnect multiple IntelliVue Access Points to one or
more Philips Access Point Controllers (APC).

The key function of the ITS infrastructure is to transport data from the transceivers
and wireless bedside monitors over a common wireless LAN-based infrastructure
(part of the IntelliVue Clinical Network) to/from the IntelliVue Information Center
where the data can be recorded or used to alert clinical operators as to a change in
monitored parameters.

ITS Standard

Access Points

Five major components comprise the Philips IntelliVue Telemetry System
infrastructure:

• 1.4 GHz or 2.4 GHz IntelliVue Telemetry System Smart-hopping Access Points

• Access Point Controller

•Synchronization Unit

• Power over Ethernet Unit

• Uninterruptible Power Supply

ITS Smart-hopping Access Points

The IntelliVue Telemetry System supports two types of Smart-hopping Access
Points:

• Standard Access Points (Model M4842A for 1.4 GHz and
Model ITS4852A for 2.4 GHz ITS)

• Core Access Points (Model ITS4843A for 1.4 GHz ITS only)

The IntelliVue Telemetry System Standard Smart-hopping Access Points (APs)
(Figure 1-2) provide an air-link to transmit and receive data between patient-worn
transceivers and the Philips IntelliVue Information Center via the ITS infrastructure.

The effective range of each Standard AP is typically 32 feet (9.8 m), and each
Standard AP supports up to 18 wireless clients (i.e., patient-worn transceivers or
bedside monitors). When monitored patients are ambulatory, patient data is
handled seamlessly between the other IntelliVue Access Points in the system. The
Standard AP is normally used with two antennas attached to it. Standard APs can be
mounted out of the way on corridor walls, or above or below ceiling tiles.

• Serial Port - The serial port is used only for manufacturing purposes.

• Ethernet Interface - The AP provides a 100 Base-T Ethernet interface with an
RJ-45 connector to connect the AP to the ITS Sync Unit.

The AP Ethernet interface provides data communications to and from the
IntelliVue Information Center over the ITS LAN infrastructure. It also presents
the 48Vdc power and synchronization signals required by the AP. The
synchronization signal is superimposed on the power supply voltage. You must
attach a ferrite block to the CAT 5 cabling (from the Sync Unit) no more than 20
inches (50 cm) from the RJ-45 connector to reduce electromagnetic (radiation)
interference. Table 1-1 lists the pin signals for the AP Ethernet interface.

Standard AP Status LEDs

The ITS Standard Smart-hopping AP provides seven status LEDs.

• Wireless/RF Activity - The AP provides three LEDs to indicate wireless/RF
activity. During normal operation, these LEDs indicate the following information:

- Power/Sync LED - GREEN (ON) when power and synchronization signal is

present.

- Network LED - Normally OFF (not lit) - flashes green to indicate network

activity.

- Radio LED - Normally OFF (not lit) - flashes green to indicate network activity.

For 2.4 GHz standard APs, the three LEDs above can be viewed from the APC
web interface.

At initial power on the AP runs a Power On Self-Test (POST). During the POST, the
above LED indicators flicker and then all three will illuminate continuously
(AMBER) to indicate correct startup operation. Then, the Power ON LED will
illuminate (GREEN) continuously to indicate that the 48Vdc power and sync
signal are being supplied, and the other two (AMBER) LEDs turn off (not lit).

• Wired/Ethernet Activity - The AP provides four LEDs to indicate wired/Ethernet
activity. During normal operation, these LEDs indicate the following information:

- Act LED - Transmit activity. Flashes GREEN (ON) when there is activity is over

the wired network.

- Link LED - Link present/Ethernet connection. Lights GREEN (ON) when a

pass-through link is present - OFF when not present.

- 100M LED - Link Speed. Lights GREEN (ON) (GOOD) for a 100 Base-T

(100Mbps) connection - OFF (not lit) (BAD) for a 10 Base-T connection.

- FDX LED - Receive activity. Lights GREEN (ON) (GOOD) to indicate Full Duplex

connection. OFF (not lit) indicates Half Duplex connection (BAD).

Figure 1-4: IntelliVue Telemetry System Core Access Point (Model ITS4843A)

The Core AP is a modular antenna infrastructure consisting of a Core AP (CAP) with
up to two connected Model ITS4846A Remote Antennas (RAs). A 68-foot (20.7m)
coaxial and unshielded twisted pair (UTP) cable bundle is used to connect a Remote
Antenna to a Core AP. Core APs are only available for the 1.4 GHz ITS.

The effective range of the Core AP and of each Remote Antenna is typically 32 feet.
The Core AP always supports a maximum of 18 wireless clients (i.e., patient-worn
transceivers or bedside monitors) regardless of its component configuration. A Core
AP alone supports 18 wireless clients. When used with a single RA, the Core AP
supports nine wireless clients and its connected RA supports nine wireless clients
(9+9=18). When used with two RAs, the Core AP supports six wireless clients and
its connected RAs each support six wireless clients (6+6+6=18).

When monitored patients are ambulatory, data roaming is handled seamlessly
between the other IntelliVue Access Points in the system. The Core AP and each RA
are always used with their two supplied antennas installed. The Core AP and its
attached Remote Antennas can be mounted out of the way on corridor walls, or
above or below ceiling tiles.

Philips provides ITS Core Access Points for the 1.4 GHz US Wireless Medical
Telemetry Service (WMTS) band (P/N 862228) with one or two optional Remote
Antennas.

IntelliVue Telemetry System Infrastructure Installation and Service Guide 1-9

Figure 1-6: IntelliVue Telemetry System Access Point Controller

Chapter 1: Overview

Front Panel

LEDs

The following status LEDs are provided on the APC front panel:

• Power LED - The Power LED is a multi-color LED that indicates the following
status:

- AMBER - During initialization, the Power LED is illuminated AMBER.

- GREEN - During normal operation, it is illuminated GREEN continuously.

- RED - If there is an internal problem with the APC, the Power LED will

illuminate RED. If the Power LED is lit RED, try recycling power to the APC. If it
remains lit RED, then the APC will need to be replaced

• Network Utilization LEDs - These LEDs provide indication (as a percentage) of
the amount of network traffic between the APC and the Access Points. When the
LED on the far left is ON but the rest are OFF, the network utilization is low, less
than 20%. As the amount of traf fic increases, more LEDs will turn ON to indicate
an increase in the percentage of network utilization. When all six LEDs are ON,
the network utilization is greater than 90% of the AP Controller’s total capacity.
The utilization value is updated ten times per second. In addition, the LEDs
indicate the peak utilization for the previous three seconds by illuminating the
LED that corresponds to that utilization percentage. For example, you may
notice that all six LEDs turn ON momentarily and then the fourth and fifth turn
OFF while the sixth remains ON. The sixth LED is ON to indicate peak utilization
reached 90% within the last three seconds.

Rear Panel

Connectors and

LEDs

The following connectors and status LEDs are provided on the APC rear panel:

• Power Receptacle - Connect the APC an AC power source that provides 100 ­240 VAC, 1.5A max, at 50/60Hz.

• Serial Port - Use the APC serial port to connect your service PC to the APC
command line interface (CLI) to complete basic initial configuration the APC.

• Ethernet Port - The APC provides a 100 Base-T Ethernet interface with an RJ-45
connector to connect the APC to an available port on the ICN network switch.

• 100 Base-T LINK LED - Illuminates GREEN continuously when the APC has
established a 100 Mbps (NORMAL) connection. The LED is OFF when the APC
has established a 10 Mbps connection.

• LINK/ACT LED - This LED reflects link integrity as well as activity. When the
Ethernet LAN cable is physically connected to the Ethernet LAN (RJ-45
receptacle), the LED will illuminate YELLOW. When the cable is attached the
LED will remain ON/lit, and when there is activity, at which time the LED will
blink OFF momentarily. If there is a problem with the link, then the LED will
remain OFF (although the LED will blink ON momentarily when the unit attempts
to send data through its Ethernet port). A problem with an Ethernet link is
typically due to a damaged or improper Ethernet cable, or to a damaged port on
one of the linked devices.

• MASTER/SLAVE Toggle Switch - MASTER/SLAVE toggle switch (set manually) to
indicate the master SU of an installation. This MASTER switch disables the
alarm that would be generated by the lack of an upstream unit to provide a
reference signal to this unit. Slave units should receive a reference feed from a
master SU, and should be switched to the SLAVE position (operation). If the
reference feed fails, these units will free-run, and will also generate a technical
alarm.

• CABLE DELAY Switch - 10 Position rotary step switch compensates for cable
delay - lowest delay position 1 to highest delay position 10. Each switch
increment represents 50 m cable length.

• EXT 10MHz REF - Not used currently.

General Intellivue Telemetry System Data Flow

Data sent from the ITS transceiver to the IntelliVue Information Center traverses the
network as follows:

1. The transceiver sends its ECG data over the wireless link to an ITS Access Point.

2. The AP then “wraps” the ECG data into another message packet, with its
destination as the Access Point Controller that is assigned to handle the
management activities for that AP.

3. The wired network then treats the packet like a message to the APC.

4. The APC receives the packet, “unwraps” it and determines that the message is
for the IntelliVue Information Center.

5. The APC repackages the message and forwards it on with a destination address
of the IntelliVue Information Center.

Data sent from the IntelliVue Information Center to a patient-worn transceiver
traverses the network as follows:

1. The Information Center sends a message to the transceiver’s IP address. The
network “sees” the location of the transceiver’s IP address as the location of
the APC, and sends the message there.

2. The APC then looks at the message, determines which ITS Access Point is
currently connected to the transceiver it needs to send the message to, “wraps”
the message into a packet and forwards the packet on to the appropriate ITS
Access Point.

3. The network handles the packet as a message for the ITS Access Point.

IntelliVue Telemetry System Infrastructure Installation and Service Guide 1-13

Chapter 1: Overview

4. When the packet arrives at the ITS Access Point, the Access Point “unwraps” the
message, determines which transceiver the message is intended for, and sends
the message on to the transceiver over the wireless link.

Defined ITS Bandwidth

The ITS transceivers (portable patient-worn devices), wireless bedside monitors,
and infrastructure operate on the 1.4 GHz US Wireless Medical Telemetry Service
(WMTS) band or on the 2.4 GHz band for deployments outside of the US.

1.4 GHz ITS Bandwidth

In the United States, the IntelliVue Telemetry System operates in the radio bands of
1395 – 1400 MHz and 1427 – 1429.5 MHz. The FCC has designated this spectrum
(WMTS) for use by Medical Telemetry devices.

government communications, etc.):

• Pittsburgh, PA

• Metro Washington D.C.

• Richmond/Norfolk, VA

•Austin/Georgetown, TX

•Battle Creek, MI

•Detroit, MI

•Spokane, WA

In these seven areas, in contrast to the rest of the US, WMTS has primary status in
the 1429-1431.5 MHz band, but is secondary to non-medical telemetry operations

Required FCC

Registration

The FCC (Section 95.1111 of the FCC Rules) requires that all WMTS transmitters be
registered with the American Society for Healthcare Engineering (ASHE). If a
hospital doesn’t register, not only is it subject to being interfered with, but the FCC
can also shut down its telemetry system.

Hospitals using the IntelliVue telemetry System must register all 1.4 GHz patient­worn transceivers, wireless bedside monitors, and Access Points and Remote
Antennas.

Site registration with the frequency coordinator, American Society for Healthcare
Engineering (ASHE), is only required once and can be done online (www.ashe.org).
The frequencies and number of devices in use must be logged with the frequency
coordinator.

2.4 GHz ITS Bandwidth

Outside of the United States, the IntelliVue Telemetry System uses RF energy in the

2.4 GHz frequency space across 48 radio channels assigned from 2401.066 MHz

to 2482.272 MHz, with a channel spacing of 1.728 MHz.

Table 1-7 lists the 2.4 GHz ITS channels.
