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
