According to Digium
, they just released their 8-port T1/E1 card designed for high density Asterisk deployments. The TE820 includes eight independently software-selectable digital telephony interfaces, supporting up to 192 channels (in T1/J1 mode) or 240 channels (in E1 mode).
In a Digium email announcement, Digium claims this is the highest single-card port density available for use with Asterisk - though Sangoma's A108 Octal 8-port T1/E1 card
might have something to say about that.
Features/Specs of the TE820:
- 8 T1 / E1 Spans using 4 RJ45 connectors (each supporting 2 circuits). Break out dongles included.
- Up to to 192 (T1/J1) or 240 (E1) concurrent calls per card
- PCI Express form factor / half-length, full-height card
- Interfaces are software selectable (T1, E1, or J1 Mode)
- Optional 128ms hardware echo cancellation module
The TE820 card supports industry standard telephony protocols, including multiple variants of Primary Rate ISDN. Each span can be configured as either CPE or network. The optional VPMOCT256 hardware echo cancellation module is based on the renowned Octasic chipset, which offloads the task of echo cancellation from the CPU, thereby increasing performance and call quality. You can also add this echo cancellation module later if you like. The card obviously works quite nicely with Asterisk software, which is used in PBXs, gateways, and other telecom applications.
