1). The E1/T1 Card is with 1 E1/T1 port
2). Supports Issabel ,asterisk,FreePbx....
3). It is with Low Profile for 2U server.

The T1/E1 card is a single span, selectable T1 (24-channel) or E1 (32-channel) card that supports all the functionality of Issabel /Freepbx.
This card supports both voice and data modes on its single span.
For example, the asterisk card can support 12 channels dedicated to voice and 12 to data while passing all traffic through to the 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 brings a high-performance, cost-effective, and flexible single span togglable T1/PRI or E1/PRI interface to the line-up of telephony interface devices.
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 card is fully supported open source voip PBX software.
