Overview

GL's handheld telecom test instruments are simple and easy to use and are designed to test almost any network interface including TDM (Analog, T1, E1, T3, and E3) and IP (Ethernet) networks. They are portable, battery operated, rechargeable, and light.


Brief Description of our Latest Handheld Portable Products

IPNetSim™ Handheld - Ethernet, IP, WAN Network Emulator

GL's IPNetSim™ - Handheld is a handheld battery operated instrument that can simulate real-time IP and Carrier Ethernet network dynamics by means of hardware controlled packet delay, loss, jitter, errors, bandwidth constriction, congestion, and duplication. IPNetSim™ Handheld simulates network behavior of up to 1 Gbps rates with accuracy always better than 1ms. IPNetSim™ Handheld is equipped with a hardware based impairments generator, and dual GbE ports.

Some of the important Features

  • Shape and manage up to 16 independent flows of traffic with predefined QoS.
  • Impairment generation on each flow including Latency, Packet Loss, Duplication, Delay, Jitter
  • Impairments as per ITU-T Y.1541 standard
  • Jumbo frames support up to 17 kBytes
  • Traffic shaping and Traffic Policing
  • Events: Packet loss, delay, error, duplication, jitter, bandwidth limitations, and congestion,
  • Events are implemented at Ethernet layer

LinkTest™ Dual E1 - E1, DataCom, Jitter, Wander Testing

GL's LinkTest™ Dual E1 is a handheld dual-port tester for E1 and data communications (V.11 / X.24, V.24/RS232, V.35, V.36/RS449, EIA-530, EIA-530A) interfaces. With the support of a large range of software options for E1 services and sub rate multiplexing system, this handheld unit provides a scalable test solution for E1 and data testing. It provides a large, clear screen with a full set of physical layer tests for E1 balanced and unbalanced circuits including BERT, VF, round trip delay and signal level.

Some of the important Features

  • Multi-interface capability: V.24/RS232, V.11/X.24, V.35, V.36/RS449,
  • Supports ITU-T G.711 encoding with A law, G.703 (E1 2.048 Mbit/s), G.704, G.703 co-directional
  • ITU-T G. 821, G. 826, and M. 2100 performance analysis
  • Supported Line codes – HDB3 (High-density bipolar with three zeroes), AMI (Alternate mark inversion)
  • Rugged, handheld, battery operated, low-cost, and software upgradable design for field use
  • Carry out generation and analysis of both framed signals (as per ITU-T G.704) and unframed tests
  • Collection of call records from remote locations
