SinoV***0DE
1 E1 PCI-E digital card without EC module
SinoV***0DE-EC 1 E1 PCI-E digital card
with EC module
The SinoV***0DE is a with 1 ports,
selectable E1 (**-channel) or T1 (**-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 *2 channels dedicated to voice and *2 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.
By utilizing our TDMoE technology,
an exclusive Digium process, one can easily connect multiple PCs
equipped with the card and achieve voice quality on par with single
PBX implementations. Scalability for this product is derived from
adding multiple cards to each individual PC. Add addition cards as
you need them for your expanding applications.
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.
Of course, the asterisk card is
fully supported by Digium open source Asterisk PBX software. Used
in conjunction with Asterisk, the card offers the power to create a
seamless network, interconnecting PSTN with the emerging Voice-over
IP technologies. The card can be used to deliver a wide range of
PBX and IVR services to the network or handset including Three-Way
Calling, Call Conferencing,Voicemail ,and VoIP Gateways.
