# Agilent E1616A 1.5/45 Mb/s (DS1/DS3) Line Interface Module (Pre-Owned) # Agilent E1616A 1.5/45 Mb/s (DS1/DS3) Line Interface Module (Pre-Owned) ## Key Features At A Glance - Selectable DS1 (1.544 Mb/s) or DS3 (44.736 Mb/s) operation in a single module - Selectable direct or PLCP mapping per ANSI, ITU-T G.804, UNI 3.0, and Bellcore TR-TSV-000773 - Cell-based ATM generation and analysis at the physical and ATM cell layers - Internal traffic generator with 1 foreground channel and up to 100 background channels - Three operating modes: Terminal, Repeater, and Local Loopback - Physical layer error and alarm generation including AIS, Yellow, IDLE, and bit error injection - ATM cell capture (1,500 cells) and PLCP frame capture (256 frames) with manual or event triggering - Single-slot C-size VXI card designed for the E4200/E4210 BSTS chassis The Agilent E1616A 1.5/45 Mb/s (DS1/DS3) Line Interface is a single-slot module for the Broadband Series Test System (BSTS) that generates and analyzes ATM cell streams contained within DS1 or DS3 framing formats. Operating as part of the modular E4200/E4210 BSTS platform, the E1616A delivers test capability at both the physical and ATM cell layers, supporting direct and PLCP mapping schemes across the two transmission rates from a single instrument. The datasheet identifies the E1616A's applications across the Broadband Series Test System ecosystem: R&D engineering, product development, quality assurance, performance testing, type approval, and conformance testing of ATM and B-ISDN equipment. The module is used for transmission test functionality including traffic generation, cell error/loss/delay measurements, and traffic capture and playback. It pairs with other BSTS line interfaces, the E4209 Cell Protocol Processor for ATM and adaptation layer testing, and the E4219 ATM Network Impairment Emulator for impairment-based performance characterization. ValueTronics International specializes in legacy modular test platforms like the Agilent Broadband Series Test System and the line interface modules built for it. Modules like the E1616A are inventoried, inspected, and tested at our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where our technicians verify functional operation of these cards against the documented performance and confirm the accessory and configuration details before shipment. For labs maintaining established BSTS installations or sourcing replacement modules for production test systems built around this platform, having a domestic source that handles the hardware professionally — rather than relying on unverified marketplace listings for a discontinued modular platform — meaningfully reduces the risk of receiving a non-functional card. ## Brand Heritage The E1616A was originally developed and sold by Hewlett-Packard's test and measurement division and carries the Agilent Technologies branding from the 1999 spin-out of HP's test and measurement business. Agilent's electronic measurement business was subsequently transferred to Keysight Technologies in 2014. The Broadband Series Test System product line, including line interface modules like the E1616A, has been discontinued and is no longer in active production; documentation and historical product information remain associated with the Agilent and Keysight names depending on the era. ## Product Core & Specifications Category Parameter Specification Modes Tx/Rx Modes Terminal, Repeater, Local Loopback Total Bandwidth (DS1) 1.413 Mb/s Total Bandwidth (DS3) 40.704 Mb/s ATM Cell Generation Modes User-Network Interface (UNI) or Network-Node Interface (NNI) HEC Automatic generation Fill Cells Idle or unassigned Channel Priority Order Foreground, background, CPP (highest to lowest priority) Channel Control VCI, VPI, GFC, Payload Type, Cell Loss Priority SAR-PDU Support AAL-0, AAL-1 Foreground Channel Bandwidth DS1: 100 b/s to 1.413 Mb/s;
