HP E1613A 6.3 Mb/s (J2) Electrical Line Interface

The HP E1613A 6.3 Mb/s (J2) Electrical Line Interface generates and analyses ATM cell streams contained within a J2 framing format as used by the user-network interface (UNI) of NTT's ATM Cell Relay service. It is a single-slot module that provides test capability at the physical and ATM cell layers for the HP E4200/E4210 Broadband Series Test System.

The industry-standard HP E4200/E4210 Broadband Series Test System (BSTS) is ideal for R&D engineering, product development, field trials and quality assurance. It supports the widest variety of standard interfaces of speeds up to 622 Mb/s, the broadest, most powerful range of signalling capabilities, the industry's most complete automated conformance test suites, time-savings features for monitoring, emulation, simulation, load generation, performance and automated testing.

Line interface modules can perform physical layer testing with a minimal BSTS configuration consisting of a line interface module and chassis.

Complete range of test software applications and dedicated test modules are available to perform upper layer testing.

Add the HP E4209 Cell Protocol Processor provides monitoring and simulation test functions at the ATM and adaptation layer by executing optional protocol testing software applications. The CPP performs many functions in hardware that are usually done in software -- such as an automatic segmentation and reassembly engine for sophisticated real-time ATM, AAL and other higher layer protocol testing.

The HP E4219A ATM Network Impairment Emulator module lets you find the limits of performance by inserting impairments into an ATM cell stream.

[ Features ]

Cell based implementation
Supports J2 framing format (NTT specification)
Operates in Terminal, Repeater, and Local Loopback modes
Provides physical layer measurements as well as error generation
Internal traffic generator has 1 foreground channel and up to 100 background channels
Works with Cell Protocol Processor

[ Specifications ]

Modes
Three Tx/Rx modes are available. In Terminal mode, full signal
generation and analysis functions are available. In Repeater mode,
the received signal is re-transmitted (physical layer loopback).
In Local Loopback mode, the transmit signal is electrically looped
to the receiver.


ATM Cell Generation
The transmitted cell stream can contain ATM cells generated by the 
HP E1613A and ATM cells generated by an optional HP E4209 Cell 
Protocol Processor module. ATM cells generated on-board can consist 
of one foreground channel to stimulate the channel under test, and 
up to one hundred background channels for loading purposes. Fill 
cells are used to occupy unused bandwidth.
