The HP E1614A 6.3 Mb/s (J2) Optical Line Interface generates and analyses ATM cell streams contained within a J2 framing format with 6.3 Mb/s and 1.5 Mb/s overheads 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 maudle and chassis.
Complete range of test software applications and dedicated test modules is 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.

Product Index page.
ModesThree 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 internally by the HP E1614A 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 backgroundchannels for loading purposes. Fill cells are used to occupy unused bandwidth. ATM cells are mapped into octets 1 through 96 of the G.704 frame payload. Octets 97 and 98 are used for framing and alarms for the four 1.5 Mb/s channels. Total Bandwidth 6.144 Mb/s Modes User-Network Interface (UNI) or Network-Node Interface (NNI) HEC Automatic generation Fill Cells Idle or unassigned Channel Priority Order OAM Fault-Management cells, foreground, background, CPP (highest to lowest priority) Channel Control VCI VPI GFC Payload Type Cell Loss Priority SAR-PDU Support AAL-0 AAL-1

ATM Erroring Control Error conditions can be introduced to simulate alarm signals and signal stressing. Error stressing is used to generate incorrect bytes in a test signal. Error Stressing Control Off On Pulse On (error condition is normally off; pulses on) Pulse off (normally on; pulses off) Sequence On (normally off; alternates on/off/on) Sequence Off (normally on; alternates off/on/off) ATM Error Injection Cell header or payload bytes with bit error masking Cell Loss Sequence number in the SAR-PDUis skipped and a fill cell is inserted PRBS Error Add Single bit error add to the PRBS pattern in the cell payload OAM Fault Management VP/VC-AIS and FERF cells transmitted at a rate of one per 0.2 to 10 seconds continuously or in bursts of 1 to 63 F4 or F5 level Segment and end-to-end OAM flows are supported Payload octets 2 to 46 can be edited Bit error masking on payload octets 2 to 48
