Asterisk 4E1/T1 PCI/PCI-E card

The RT-420D supports Up to 4 E1/T1 channels,and provides up to 16.4Mbps of full duplex data throughput or 120 voice calls over four T1 and or E1 lines to support high performance PCI-based routing and telephony systems. Because the WSS-4E/T1 improves I/O speed by up to 10 times, the result is reduced CPU usage and increased card density per server.

 

The RT-420D is a with 4 ports, selectable E1 (32-channel) or T1 (24-channel) card that supports all the functionality of the Digium quad T1/E1 card. This card supports both voice and data modes on its single span. For example, the card can support 12 channels dedicated to voice and 12 to data while passing all traffic through to the Asterisk PBX, which reliably routes the channels to their designated locations. This eliminates the need for an external router.


The card supports industry standard telephony and data protocols, including both RBS and Primary Rate ISDN (PRI) protocol families for voice and PPP, Cisco HDLC, and Frame Relay data modes. The board drives both line-side and trunk-side interfaces, including call features.

The card is a compact and powerful interface supporting voice and data transmission over T1, E1, and Primary Rate ISDN (PRI) connections. A low profile, half-length PCI form factor allows this device to fit within a 2U rackmount case or equivalent chassis, offer excellent density for call center, service provider, and other space-sensitive applications.
