GL Communications Inc. in a press statement, conveyed today the availability of its versatile PCI Based Universal T1 E1 Cards- that provide comprehensive and versatile T1 or E1 testing capability. Mr. Vijay Kulkarni CEO of the company said, "The Universal HD T1 E1 is an enhanced PC-Based T1 and E1 solution that utilizes familiar computer user interfaces, to provide comprehensive and versatile T1 or E1 testing capability at a competitive price.

The Universal HD T1/E1 card is capable of both T1 and E1 interfacing. This features in-service monitoring and emulation of T1 and E1 circuit connections. It provides out-of-service troubleshooting such as bit-error-rate testing, alarm monitoring, signaling bit manipulation and recording, DTMF/MF generation and detection, and Drop and Insert capabilities."

He added, "The T1 (E1) Pulse Mask Application compares incoming T1 (E1) pulses against the pulse shape mask specified by the ITU G.703 standard. Jitter measurement application can measured in the incoming T1/E1 signal for any unwanted variations. Graphical views simplify the understanding of PCM data. Time-domain is presented using an oscilloscope display, and frequency domain using spectral displays. Besides providing access to in-band PCM data, the T1 (E1) provides VF interface for monitoring and inserting audio with Drop and Insert. The unit also provides convenient handset interface for voice over the T1 or E1 line."

Mr. Kulkarni further added, "Remote testing and monitoring can be done using simple script based or GUI based client software.

Precision Delay Measurement under basic software measures the Round trip Delay of a system. Round trip delay measurement is done by sending a BER pattern with the insertion of an errored bit and timing the reception of the errored bit. Measurement is precise and accurate to the microsecond level. A delay up to 8 seconds can be measured. The internal delay of the card is subtracted from the round trip delay."

• Universal Boards are capable of T1 and E1 interfacing. Only software drivers differentiate whether T1 or E1 signals are being processed.
• Universal boards can be plugged into either a 5 V or 3.3 V PCI bus., i.e. (PCI 2.1 Complaint)
• Smaller Size - The boards are smaller, with dimensions are 4.2" x 7.1" vs. the older boards 4.2" x 9.2"
• High Density and High Speed - The boards are significantly faster, and significantly more efficient than the older boards. The new boards use DMA and a 32-bit wide bus.
• CPU Utilization - CPU utilization with the boards is negligible. For example, one can simulate echo on hundreds of timeslots by running simultaneously "delay/attenuate" on all 24 T1 ports on all timeslots. The new boards are compatible with dual processor motherboards and software that simulates dual processors (i.e. hyperthreading)
• Universal boards have adjustable transmit clock frequency (+ / - 300ppm) for testing frequency lock sensitivity of T1 or E1 equipment. The transmit clock can be adjusted + / - 300 PPM
