Digium just announced the release of two new products: the TE820 Octal Digital Interface Card and the R-Series family of redundancy / failover appliances.

The TE820 is an eight-port digital interface card. It can handle up to 8 T1, E1 or J1 connections. That's up to 192 concurrent calls in T1 or J1 mode, or 240 calls in E1 mode, making it the highest-density card made for use with Asterisk. As an optional enhancement to TE820, we are also launching the VPMOCT256, an echo cancellation module that can handle up to 256 concurrent calls. The TE820 will be available in PCI Express form factor.

The TE800 Series cards consists of 4 RJ45 ports and eight status LEDs. The ports are used for connecting T1, E1, or J1 cables via Y-adapter dongles, which are included in the shipment of the TE800 Series card. The TE800 Series cards can be used without Y-adapter dongles, but only spans 1 through 4 will be accessible.

Digium’s Redundancy Series (aka “R-Series”) products are a family of inexpensive, versatile appliances that enable physical-layer failover of analog (POTS) and digital (T1, E1, PRI or BRI) telephony connections to Asterisk-based communications systems. The R-Series devices allows Asterisk administrators to create high-availability solutions that insure uninterrupted business communications, even in the event of a catastrophic hardware or software failure.
