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

Hot swap and automatic configuration

Operating modes The interface pod has four operating modes: full-duplex, transmit

Application The HP E5123A STM-1 Electrical Interface Pod requires an E5200A base

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 automatically conﬁgures the receive and transmit parameters according to the signal it receives.

Online Help

The User Online Help provides all the information you need to use the analyzer. Use the following sections to learn how to performtasks:

• Getting started

• Monitoring

• Capturing

• Running tests

• Simulating

• System administration

Use the Reference section to ﬁnd information about framing formats, alarms, errors, and measurements.

To Access User Online Help

There are four ways to access information in the User Online Help.

• Click the Help button that appears on most screens and windows to display information about that screen or window.

• From the main screen Help menu, select User to display the User Contents screen.

• Press F1. If the cursor is in an input ﬁeld, you see help for that ﬁeld; otherwise you see the User Help Contents screen.

• Press Shift+F1, or from the main screen Help menu, select Help on Item, to change the mouse pointer into a question mark (?). Move the question mark around the screen and place on the item for which you want help; then click the mouse. Use this option to get help on non-input ﬁelds.

(green LED) Lights each time the interface pod is accessed by the network.

(yellow LED) Lights when a valid signal is present at the input connector. (BNC) Accepts an electrical signal from the SUT. (BNC) Provides a signal to the SUT.

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.
