TE405/410 Interface Card

Description: OpenSS7 Hardware Selection TE405/410.


These cards are no longer supported. Use one of the C400P/E cards instead. These cards are long deprecated and no longer supported by any OpenSS7 driver.


The TE405 and TE410 cards are 4- E1/T1 PCI cards manufactured by Digium. The figure below shows a picture of a TE405 card.

(Not as shown.)

The TE405 and TE410 cards have the lowest level of signalling performance due to the lack of on-board HDLC functions. Transfers to the host processor over the PCI bus use PCI I/O ports and memory mapping.

Driver

These cards are supported by the X410 driver. (But see the Status page for this card.)

The function of the TE405/410 Channel driver is to provide for the termination of 2.048Mbps, 1.544Mbps, 64kbps and 56kbps digital paths. This driver provides direct access to the channelized or unchannelized T1 or E1 digital paths to OpenSS7 media and signalling protocol modules as well as providing T1 or E1 management, framing, coding, alarms, and synchronization.

Features

Following are some features of the TE405/410 card:

  • 4 T1 or E1 spans per card.
  • Sierra framer.
  • PLX PCI 9030 PCI bus chip.
  • Xilinx Spartan XC2S50 processor.
  • Raw transfer of octets from framers to PCI bus.
  • Uses OpenSS7 Soft-HDLC engine for SS7, ISDN and ISO.
  • 96 channels per card (T1)
  • 124 channels per card (E1).
  • Full span addressable.

Advantages

Following are the advantages of the TE405/410 card:

  • Medium cost.
  • PC Compatibility.
  • Runs on high speed buses.
  • Zaptel driver support.

Disadvantages

Following are the disadvantages of the TE405/410 card:

  • Lower performance.
  • No on-board HLDC.
  • Cannot TDM switch on card or between cards, media channels must be transferred through host to switch between cards.
  • I/O Port and Memory Map instead of PCI DMA bus-mastering and burst transfers.
  • No integrated Ethernet for SIGTRAN and VoIP applications.
  • Synchronization per-card instead of per-system.

Ultimately, the performance limiting factor of the TE405/410 cards is the bandwidth of the PCI bus and the ability of the processor to perform Soft-HDLC and TDM switching in software. A 350MHz processor is capable of processing the bandwidth of an entire TE405 E1 card (124 signalling links) with a combined link throughput of 8.192 Mbps.

For the OpenSS7 VoIP Switch, this performance is more than adequate. A medium grade 2GHz PC should be capable of handling 2 cards (248 SS7 links) with adequate excess capacity available for background operations.

These cards are very cost-effective and can provide 64kbps SS7 links at average incremental interface cost of approximately $8.00 USD per signalling link.
