GL's Octal & Quad T1 E1 boards are high density and provide Four (4) or Eight (8) RJ-48 T1 E1 ports and multiples thereof. For example, configurations of 8, 12, 16, 64 T1 E1s in a single rack are possible.

GL's new STM-1 Mux is a cost-effective, compact (only 1U high), SDH (Synchronous Digital Hierarchy) multiplexer that is designed for applications in metro and access networks for efficient transport of traditional TDM and emerging data traffic.

GL's new tProbe™ is an enhanced version of our popular USB based T1 E1 VF Analyzer / Emulator. This hardware incorporates all the features of the previous analyzer such as portability, USB interface, remote accessibility, scripting, and a vast collection of optional applications.

The LightSpeed1000™ is our new dual OC3 / 12 STM1 /4 PCI-Express card for protocol analysis and emulation of ATM, POS, RAW, and Ethernet traffic. The card also sports 2 GigaBytes of DDR2 RAM, a GigE, and a USB 2.0 interface making this card one of the most versatile and powerful cards in GL’s repertoire.

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.

The Ultra T1 or E1 Analysis Cards (PCI) plug into any PC and convert it into a complete T1 and E1 test platform. The Ultra Cards are available with either a single or a dual interface. A wide ranging set of software applications are available to meet your particular testing needs.

GL's new USB based T1 E1 Analyzer is the world's most powerful, full featured, and complete BERT, voiceband, data, signaling, and protocol analyzer in the market. It can perform analysis and emulation of various signal types including voice, digits, and tones; various protocols including HDLC, ISDN, SS7, CAS, Frame Relay, GSM, GPRS, CDMA, and UMTS.

The T1 E1 J1 Switch provides non-intrusive failsafe monitoring and intrusive test and diagnostic capability for up to 8 full duplex T1, E1, and J1 lines. The unit provides two RJ-48c connectors for a thru connection for equipment and line connections and a Rj-48c monitor connector for monitoring both directions of a full duplex high speed line.

The Ultra T3 Analysis Cards (PCI) plug into PC expansion slots and provide digital T3 input/output for analyzing, testing, simulating, and monitoring T3 signals.

The Ultra OC-3 / STM-1 card (PCI) plugs into a PC expansion slot for analyzing, testing, simulating, and monitoring OC-3 and STS-1 signals.The Ultra OC-3 / STM-1 card may be used in conjunction with GL's Ultra T1 Card, Ultra E1 Card and Ultra T3 Card in the same PC to provide a complete OC-3 / STM-1, STS-1/STM-0, DS3, DS1, E1 and DS0 testing solution.

The T1 (or E1) Multiport Repeaters generate multiple identical T1 (or E1) outputs for each T1 (or E1) input. The repeaters are ideal for multicast (broadcast) applications and in lab environments for load testing and signal duplication purposes.

The GL Voice Recorder is used to manually capture the voice/data over a 2-wire Analog interface. Using the 2-wire Phone Tap adaptor, one can non-intrusively ‘tap’ into the analog 2-wire line via the RJ11 interface and capture the bi-directional voice/data. The recorded voice/data is automatically saved into a single PCM file.

The DCOSS APS (Analog Phone Simulator) converts a GL DCOSS into an analog phone simulator that simulates a bank of up to 384 analog telephones. Using a basic DCOSS with T1 trunks along with the APSCB24/48 external boxes, the DCOSS APS may be used to test a Central Office (CO), PBX, Gateway, or other telecommunications equipment, which provide local loop interfaces.

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.
