Overview
The ULTRA T1 (E1) is an enhanced third-generation product that consolidates the essential pieces of industry-standard test
equipment into a powerful, PC-Based T1 and E1 solution. Utilizing familiar computer user interfaces, it provides comprehensive
and versatile T1 or E1 testing capability at a competitive price.
The ULTRA T1 (E1) Card transforms your PC into a sophisticated T1 or E1 analyzer. Prior versions of the Ultra T1(E1) Cards were
designed for use in ISA slots, and the current Ultra T1(E1) cards are PCI. The newer PCI versions are available with either a single
T1(or E1) interface or with a dual T1(or E1) interfaces.
The ULTRA T1 (E1) features in-service monitoring of T1 (E1) circuit connections, including 64-Kbps channels within a T1 or E1.
It provides out-of-service troubleshooting such as bit-error-rate testing. Drop and Insert capabilities provide access to DS0s without
disrupting service.
The ULTRA T1 (E1) can be used for routine testing of errors, such as bit errors, frame errors, and bipolar violation; signals,
including received frequency, received signal level, and data bits; and timing including signal-loss seconds, test length etc. Alarm
monitoring and time-stamped logging provide windows into the network performance.
The ULTRA T1 (E1) emulates and decodes all 24 (32) channels simultaneously for Signalling Bits, Power Level, Frequency and
Multi-Frame Data. DTMF/MF generation and detection, signalling bit manipulation and recording provide complete signalling capabilities.
Graphical views simplify the understanding of PCM data. Time-domain is presented using an oscilloscope display, and frequency
domain using spectral displays.
Voice Frequency Access: Besides providing access to in-band PCM data, the ULTRA 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.
Remote testing and monitoring can be done by remoting the PC using familiar 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.
New Generation High Density T1 and E1 Boards
The new generation T1 and E1 boards can process hundreds of channels or timeslots simultaneously on T1 and E1 lines. These
boards are smaller, more efficient, and significantly faster as compared to older PCI boards.
Comparison and advantages of the new generation High Density T1/E1 cards with the older Dual PCI T1/E1 cards are given in
the following table.
| Feature |
High Density Dual T1/E1 cards(New generation cards) |
Dual PCI T1/E1Cards (old cards) |
| Size (form factor) |
Smaller (more than two inches shorter)
Benefit: Fits inside smaller form factor PCs |
Larger |
| Speed |
Significantly Faster - uses 32 bit wide bus, and is built on Direct Memory Access (DMA) technology
Benefit: DMA technology prevents conflicts with existing devices |
Uses only 16-bit wide bus and uses older interrupt driven technology |
| PC CPU Utilization |
Very CPU efficient. Compatible with Hyperthreading and Dual Processor architectures
Benefit:The on-board processing and the DMA technology make this board very CPU efficient. This will allow the
user to put up to 12 boards per system supporting 24 independent T1/E1 ports |
CPU requirements impose a limit of 4 boards per system
Not compatible with Dual Processors or Hyperthreading |
| Highly improved on-board logic |
The new on-board chips are faster, and have larger memories. These chips can store the entire logic for supporting various
applications. Hence loading different logic to support different applications are no longer necessary
Benefit: Gives the user the ability to run special applications simultaneously and without "T1 E1 line interference"
associated with unloading and loading of multiple loads.Newer applications that exploit the above features are available
(as well as current applications are being enhanced), see below for more details |
Cannot run multiple applications that require separate loads simultaneously |
Detailed Description of Advantages
General Description
The new generation boards have item numbers HDT001 and HDE001 for "High Density Dual T1" and "High Density Dual E1".
These replace the older DPT001 and DPE001 boards. They can be distinguished from the DP-series boards by the letters "HD"
appearing on the card bracket immediately below the T1 or E1 designator (Earliest productions of this board were distinguished by
red "E1" or "T1" lettering.) The serial numbers follow the scheme below:
- HDT001s - 766xxx older DPT001s - 755xxx
- HDE001s - 866xxx older DPE001s - 855xxx
Smaller Size
GL's new "high density boards" are smaller, The new board's
dimensions are 4.2" x 7.1" vs. the older boards 4.2" x 9.2".
High Density and High Speed
The HD boards are significantly faster, and
significantly more efficient than the older boards. The new boards use DMA and a 32-bit wide bus; the older boards used an
interrupt driven scheme and a 16-bit bus; the older boards sometimes conflicted with interrupts shared by other devices.
CPU Usage
CPU utilization with the newer boards is negligible with increasing
boards in a system. With the older boards, there was a practical limit of 4 dual boards to a system - with limitations in overall
capability as well. One can easily put 12 new dual boards in one rack system running many applications on all 24 ports
simultaneously. For example, one can simulate echo on hundreds of timeslots by running simultaneously "delay/attenuate" on all
24 T1 ports on all timeslots.
Unlike older boards, HD Boards are compatible with dual processor motherboards and
software that simulates dual processors (i.e. hyperthreading).
Improved On-board Logic
- The newer boards use an upgraded FPGA to handle almost all specialized functions with a "single load" vs. multiple loads on
older cards. This permits special applications to be run simultaneously and without "T1 E1 line interference" associated with
unloading and loading of multiple loads. For example FDL applications can be run simultaneously with BERT or Error Insertion
applications.
- There are significant BERT enhancements incorporated into the FPGA hardware. These are sub-channel BERT, non-contiguous
timeslot BERT, user defined programmable patterns, independent transmit and receive BERT sections, and inverting patterns.
Bit error rate insertion has also been incorporated into the FPGA. User software to take advantage of these capabilities will
soon be developed. Xilinx loads "t1pass.bit" and "e1pass.bit" are modified to improve multichannel BERT performance.
- The FPGA will also handle "signaling bits", called CAS (Channel Associated Signaling). The older cards implemented this through
software. User software to take advantage of this capability will soon be developed.
- An application has been developed for the high density boards that make special use of the large FPGA on these boards.
This application simulates "single channel low echo path delays" and is a complement to the software version the
"delay/attenuate" software. While the older software implementation imposes an internal delay of 20ms, the newer hardware
implementation shortens the internal delay to as low as about 1 ms.
- Another special application that allows handling of "A-law all bits inverted" on T1 lines is included. In general any code
conversion such as inversion can be performed in the FPGA of the high density boards.
- Application FPGA registers are built into the application Xilinx (a control block for most operation conducted by the board)
and help in controlling various settings on the board that affect he logic operations applied to the T1/E1 stream. Applications
manipulate these registers when certain settings are applied by the user. End users are not expected to know the detail
specifications of these registers.This feature includes registers useful during remote debugging.
- Application Xilinx also includes XOR capability for voice band client.
Currently high density boards are only available in dual t1 or dual e1 port versions. Single port versions are not available.
