About the STM-1 Electrical Interface Pod
About the STM-1 Electrical Interface Pod
Overview The HP E5123A STM-1 Electrical Interface Pod is a self-contained, plug-in
module. You use it in conjunction with the HP E5200A Broadband Service
Analyzer to test and analyze a system under test (SUT).
In the transmit direction, the interface pod
• automatically calculates and inserts Section/Regenerator Section BIP,
Line/Multiplexer Section BIP, and Path BIP
• maps the ATM cells into the Virtual Container (VC)
• automatically generates the framing pattern
In the receive direction, the interface pod
• uses the A1 A2 framing pattern to frame align the electrical signal
• applies frame descrambling
• carries out pointer processing to align to the VC
• detects line errors using the Section/Regenerator Section BIP,
Line/Multiplexer Section BIP, and Path BIP
• extracts ATM cells and passes them to the measurement system

Use the “hot swap” feature to insert and remove the interface pod while
the analyzer’s power is switched on. The analyzer automatically detects
the insertion of the interface pod and configures itself accordingly.
Immediately after you connect the interface pod to the SUT, the analyzer

To Set Up the Interface Pod
To Set Up the Interface Pod
Caution Handle the interface pod with care to avoid electrostatic discharge (ESD)
damage during unpacking, installation, and operation. The connectors on
the front and rear of the interface pod are susceptible to ESD.
1 Insert the interface pod into the analyzer.
See “T o Insert the Interface Pod” on page5. The procedure is the same for
all interface pods.
2 Connect the interface pod to the SUT.
See “To Connect to the System Under Test” on page6. The analyzer
automatically recognizes and configures the interface pod.
3 If you want to change any of the configuration parameters, see “To
Manually Configure the Interface Pod” on page 9.
4
To Set Up the Interface Pod
To Insert the Interface Pod
You can insert and remove interface pods at any time, even when the
analyzer is powered on. Initially, you insert an interface pod when you set
up the analyzer. Subsequently, you insert an interface pod when you
change the physical layer interface that you want to monitor.
1 Hold the interface pod with the front panel connectors facing you and
the Hewlett-Packard logo facing upwards.
2 Insert the interface pod into Port 1 or Port 2 of the analyzer.
3 Push the interface pod firmly into the analyzer until the connector at
the rear is properly seated. The clip on the base of the interface pod
clicks into place when the interface pod is fully inserted.
Caution You must always have two interface pods inserted in the the HP E5200A
Broadband Service Analyzer while it is operating. If your operations
require only a single interface pod, insert the blank interface pod
(provided with the analyzer) into the other port. The two interface pods
are necessary to maintain a balanced airflow for cooling of internal
components and to comply with EMC standards.
5
To Set Up the Interface Pod
To Remove the Interface Pod
When you remove the interface pod, make sure you store it in a dust free
location that meets the environmental requirements listed in
“Environmental Specifications” on page 13. An electrostatic-safe bag has
been supplied for the storage of each interface pod.
Gently press on the clip
underneath the
interface pod and pull
the interface pod out of
the analyzer.
To Connect to the System Under Test
Obtain a pair of 75 Ω coaxial cables with BNC connectors. Before you
connect the interface pod to the system under test (SUT), ensure that you
have
• connected the HP E5200A Broadband Service Analyzer to the
controlling computer (workstation or notebook PC)
• inserted the HP E5123A STM-1 Electrical Interface Pod
Connect the cables to the BNC connectors on the front of the interface
pod and to the equipment or link that you want to test. For example, you
might want to test a network element (for example, switch, service
gateway), service access equipment (for example, a multiplexer, router, or
PAD), or transmission link.

Common system connections and test connections are
• non-intrusive system connection—T-piece and passive test
connections
• intrusive system connection—network element, remote loopback, and
in-line test connections
• diagnostic system connection—transmit loopback and external
loopback test connections
See the HP E5200A Broadband Service Analyzer User’s Guide or the
User Online Help for details about these system connections.
The analyzer automatically sets the interface pod transmit and receive
parameters and configures according to the signal it receives from the
interface pod. See “Automatic Configuration Parameters” on page 8 for
more details.
If you “hot swap” the interface pod while you are logged in to the analyzer,
the screen displays the message

Automatic Configuration Parameters
After you insert the interface pod and connect it to the SUT, the analyzer
automatically configures to the STM-1 electrical signal.
The analyzer sets the remaining physical layer receive and transmit
parameters to the following defaults:
• reference (internal) clock
• 20 dB input gain off
• full duplex
See also User Online Help contains information about the ATM layer automatic
configuration parameters.

Avertissement
Cet appareil répond aux normes de la
“Classe de sécurité 1” et est muni d’un fil
de mise à la terre pour votre protection.
Pour prévenir les risques de choc électrique, la broche de mise à la terre du
cordon d’alimentation ne doit pas être désactivée.
Restrictions d’utilisation
L’utilisateur se doit d’observer les mesures
de précaution énumérerais-dessous pour
toutes les phases d’utilisation, de service et
de réparation de cet appareil. Le fait de ne
pas s’y conformer équivaut à ne pas
respecter les mises en gardes spécifiques
contenues dans ce manuel et constitue une
violation des normes de sécurité relatives à
la conception, la fabrication et l’utilisation
prévue de cet appareil. La société HewlettPackard n’assume aucune responsabilité
envers un client qui manquerait de se conformer à ces exigences.
Mise à la terre
Afin de minimiser les risques de choc électrique, le châssis et le cabinet de l’appareil
doivent être mis à la terre. L’appareil est
équipé d’un cordon d’alimentation muni
d’une fiche homologuée à trois lames, compatible c.a. La prise murale et la prise
femelle de la rallonge électrique doivent
respecter les normes de sécurité de la
“Commission Électrotechnique Internationale” (IEC).
Environnement
Ne faites pas fonctionner cet appareil en
présence de gaz inflammables ou de
vapeurs dangereuses. L’utilisation de
n’importe quel appareil électrique dans ces
conditions constitue un risque élevé pour
votre sécurité.
Service et ajustement
Des “tensions dangereuses” résident dans
cet appareil. Par conséquent, le service et
l’ajustement doivent être effectué uniquement par une personne qualifiée.
Ne remplacez pas de composantes lorsque
le cordon d’alimentation est sous tension. Il
pourrait y avoir présence de “tension dangereuses” même lorsque l’appareil est
déconnecté.
Manipulation du tube cathodique
Une manipulation brusque, ou le fait de
secouer l’appareil, peut provoquer le bris du
tube cathodique. L’implosion qui s’en suivrait entraînerait la dispersion à grande
vélocité d’éclats de verre. Le retrait ou
l’installation du tube cathodique ne doit
être exécuté que par un technicien qualifié,
portant un masque et des gants de sécurité
homologués.
Service non autorisé
L’installation de pièces étrangères, ou tous
modification apportée à l’appareil sans le
consentement de Hewlett-Packard est
formellement interdit. Le fait de procéder à
de tels modifications sans autorisation
pourrait entraîner l’annulation de la garantie de l’appareil ou de tout contrat de service.
Pour un service et des réparations
autorisées, retournez l’appareil à un point
de vente et service Hewlett-Packard.
