Digium TE220 : 2 ISDN PRI paths (2 x E1), support T1,E1,J1, PCI-Express x1 3.3V slot.
Dual-port T1/E1 PCI Express Asterisk interface.
The Digium TE220 card will support up to 60 channels of voice or data from two E1, T1 or J1 interfaces in the PCI Express form factor. By selecting per-port or per-card, Digium TE220 (TE220) allows you to mix E1 and T1 with full channel synchronization. Always supporting PCIe x1, TE220 can be used in any of the available PCIe 1.0 slots: 1x, x4, x8, and x16 without worrying about power supply, voltage selection or line size.
Digium TE220 (TE220p) can be combined with the Digium VPMOCT064 Octasic echo canceller, Wikonim and DSP (Digital Signal Processor). VPMOCT064 is based on the G.168 algorithm, which has clearly shown itself in the tests to be reduced within 128 ms (1024 outputs) on all 60 channels with E1 and all 48 channels with T1/J1.
The TE220 is designed by Digium to work seamlessly with Asterisk Business Edition, AsteriskNOW and Asterisk with open source code. The TE220 supports industry standard telephony protocols, including American and European Primary Rate signaling, standard Robbed Bit, Channel Associated Signaling in addition to standard PPP, HDLC and Frame Relay data mode.
