About the STM-1 Electrical Interface Pod

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

Operating modes	The interface pod has four operating modes: full-duplex, transmit
	loopback, receive loopback, and regenerator.
Components	The interface pod is shipped with
	∙ a Calibration Certificate
	∙ this set up guide
Application	The HP E5123A STM-1 Electrical Interface Pod requires an E5200A base
	unit with Application Version number A.01.2 or greater.
