test a wide variety of communications facilities and equipment including Asynchronous, Synchronous, T1, fractional T1, E1,
fractional E1, modems, multiplexers, CSU/DSUs, T1 ESF CSUs, DU, NTUs and TIUs.
Please visit the LinkTest™ SINGLE page for more information.
- LinkTest™ SINGLE+
GL’s LinkTest™ SINGLE+ is a sophisticated bit error rate tester in a compact, hand held package. The unit
can test a wide variety of communications facilities and equipment including DDS, T1, fractional T1, E1, fractional E1, T3and
E3NTUs, multiplexers, CSU/DSUs, T1 CSUs, DTUs and TIUs.
Please visit the LinkTest™ SINGLE+ page for more information.
- LinkTest™ DUAL
GL’s LinkTest™ DUAL is a sophisticated bit error rate tester in a compact, hand held package with dual
interfaces and a full color display. The unit can test a wide variety of communications facilities and equipment including T1,
fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU/DSUs, T1 CSUs, DTUs, NTUs and TIUs.
Please visit the LinkTest™ DUAL page for more information.
- LinkSim™
GL’s LinkSim™ simulates a variety of communications links, inserting delays and inserting errors such that
the user can determine what effects these impairments will have on their systems.
Please visit the LinkSim™ page for more information.
- Laptop T3/E3 Analyzer
GL’s T3/E3 analyzer unit used in conjunction with GL’s Laptop T1/E1 analyzer provides a complete T3/E3
(44.736/34.368 Mbps), T1/E1 (1.544 Mbps / 2.048Mbps), and DS0 (64Kbps) testing solution.
Please visit the Laptop T3/E3 Analyzer page for more information.
- DCOSS BRI Phone Simulator (BPS)
The BRI Phone Simulator (BPS) converts GL's DCOSS into a BRI ISDN Terminal Phone Simulator. The BPS can simulate a
bank of up to 128 BRI telephones (terminal side), each supporting one D-channel and two B-channels. Using a basic
DCOSS with E1 PRI ISDN trunks along with a BPS external box, the DCOSS BPS may be used to test a BRI Network.
Please visit the DCOSS BRI Phone Simulator (BPS) page for more information.
- 2-Wire Phone Tap
The 2-Wire Phone Tap connects non-intrusively to any analog telephone line and to the USB Interface of a PC for
recording incoming calls and outgoing calls. Voice in both directions, Caller ID, and DTMF digits are all recorded, detected,
and decoded. The 2-Wire Phone Tap can also connect to any IP, digital, analog, or chordless telephone at the handset
curly cord point.
Please visit the 2-Wire Phone Tap page for more information.
- Audio Processing Utility Software
Audio processing utility is a pre-processing application used for manipulating the input audio (tones, and voice) files
with impairments such as delay, noise, acoustic echo, line echo, and double talk. An echo file is generated if a
corresponding line or acoustic echo filter is specified. It analyzes the given coefficients files and calculates the applied
delay & ERL. The degraded audio output file can then be visually analyzed or used for further speech analysis with GL’s
Voice Quality Testing, Digital Echo Canceller & other applications.
Please visit the Audio Processing Utility page for more information.
- Near Real-time Voice-band Analyzer Software
The Near Real-time Voice-band Analyzer (VBA) is an analysis tool for monitoring voice band network traffic. The VBA
can host different analysis modules for monitoring speech and noise levels, line echo, and acoustic echo. The standard
modules included in the application are ITU-T P.56 Active Voice Level analysis, Line Echo (Hybrid) analysis, and Acoustic
Echo analysis. Other analysis modules such as ITU-T P.561, P.562, and P.563 can be hosted as plug-ins.
Please visit the Voice-band Analyzer page for more information.
- IPNetSim™ - IP Network Simulator
IPNetSim™ can simulate an entire IP network in a single box. All the conditions encountered in a real-time IP
network are simulated such as network latency, network delay variation (jitter), bandwidth, congestion, packet errors,
bit errors and other link impairments independently in both directions at speeds of up to 100 Mbps (or1Gbps per link).
It can be used to test IP end point devices such as (Gateways, IADs, IP phones, Soft phones, and so on) for voice, fax,
data, or multimedia transmission over IP.
Please visit the IPNetSim™ page for more information.
- MC-MLPPP Emulator - For Automated Testing of PPP, MLPPP, &
MC-MLPP using Client Server
Automated testing can be accomplished using client-server based PPP, MLPPP, & Multi-Channel (MC) MLPPP
Emulation and Analysis (MLPPPTerr) module. The application permits traffic generation and verification over PPP links
and may be accessed through a GUI or through command line scripts.
Please visit the MLPPP
and PPP Emulator page for more information.
- VQuad™
GL's VQuad™ makes assessing Voice Quality between and within differing networks easy, portable, and
convenient. The system provides all necessary capability for automatic measurement of Voice Quality and QOS for
any desired network including VoIP, TDM, Wireless, or Analog. The VQuad™ VQT System provides interfaces for
wireless/WiFi phones, VoIP/Digital phones, PSTN (2-wire) phones, VoIP (SIP/H.323) and T1/E1 (ISDN and CAS). Up to
8 devices can be controlled simultaneously on a single portable system.
Please visit the VQuad™ page for more information.
