Universal T1/E1 card
-- Test & Measurement World, 11/1/2008 2:00:00 AM
GL Communications has added a universal T1/E1 PCI 2.1-compliant card to its T1/E1 analyzer hardware and software test suite with Release 5.13. The universal board can process hundreds of channels or time slots simultaneously on T1 and E1 lines.
Unlike previous versions, which required separate boards for T1 and E1, the new card has integrated hardware support for both types of lines, allowing easy switching between T1 and E1 interfaces. What’s more, it can be plugged into either a 5-V or 3.3-V PCI bus slot. The new board is also smaller than its predecessors, with dimensions of just 4.2x7.1 in. The use of direct memory access and a 32-bit–wide bus make it faster and more efficient than the older boards.
The universal card 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, DTMF/MF generation and detection, and drop and insert capabilities.
