Introduction
 

The D100 Series cards are the industry's first high density affordable PCI or PCI Express voice transcoding cards designed for optimum voice quality for low to high density systems, offering from 30 to 400 transcoding sessions (2-legged calls) in one compact 2U form factor! 

• Cards are ethernet based.
  D100 PCIe: system will recognize it as a Broadcom BCM5723 ethernet device.
                    --> Linux: Broadcom driver tg3
  D100 PCI:   system will recognize it as a Micrel ethernet device.
                    --> Linux: Micrel driver ks8842_pci
• D100 PCI/PCIe transcoding card has been designed with a general SNGTC API interface that can be used to develop transcoding applications.
  All media to and from the D100 card will be carried via RTP/IP.
• D100 PCI/PCIe can work with Asterisk & FreeSWITCH as a codec module.
• D100 Supports the following codecs (G729 is fully indemnified- no need to pay extra):
  
  

  Codec	P time (ms)		Codec	P time (ms)
  G711 ulaw	10,20,30,40,50ms (64 kbps/8 Khz)		G722	10,20,30,40ms (64 kbps/8 khz)
  G711 alaw	10,20,30,40,50ms (64 kbps/8 Khz)		GSM_FR	20 ms (13 kbps/8Khz)
  L16 linear	10,20,30,40,50ms (128 kbps/8Khz) 10,20,30,40,50ms (256 kbps/16Khz)		GSM_EFR	20ms
  G729 AB	10-200ms (8 kbps/8 Khz)		ILBC	20,40,60ms (15.2kbps/8Khz) 30,60ms (13.3kbps/8Khz)
  G723.1	30,60,90ms (5.3kbps/8Khz) 30,60,90ms (6.3kbps/8khz)		G726	10,20,30,40,50ms (32kbps/8Khz)
  G722.1 (Siren 7)	20ms (24kbps/16Khz) 20ms (32kbps/16Khz)		AMR	20,40ms (4.75kbps/8Khz) 20,40ms (5.15kbps/8Khz) 20,40ms (5.90kbps/8Khz)

  
                        
                         
  

   

 Known Issues

•  Asterisk codec module not supported for Asterisk 1.2 
• Broadcom has released a new ethernet tg3 driver for D100 PCIe cards
  that fixes a lot of  issues on new servers.
• It is highly recommended to install this driver before proceeding with sngtc installation.
  Download -- tg3-3.116j.tar.gz 
• D100 PCI cards are not fully compatible with Ubuntu systems due to a Micrel driver issue
