Chapter 1 Overview
1.1 What is Asterisk
The Definition of Asterisk is described as follows:
Asterisk is a complete PBX in software. It runs on Linux, BSD, Windows (emulated) and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in four protocols, and can interoperate with almost all standard-based telephony equipment using relatively cost-effective hardware. Asterisk provides Voicemail services with Directory, Call Conferencing, Interactive Voice Response, Call Queuing. It supports three-way calling, caller ID services, ADSI, IAX, SIP, H323 (as both client and gateway), MGCP (call manager only) and SCCP/Skinny (voip-info.org).

1.2 What is D830E/DE830E?
DE830E is a D830E with an EC module, they are new products of the Digital cards. It’s supposed to be the most advanced 8 port T1/E1/J1 Asterisk® card with superior quality in the open source community. The leading innovation ensures users to adjust the interrupt frequency to reduce the CPU load up to 70% and adjust the interrupt pin to avoid interrupt number sharing or conflict. DE830P offers an on-board Octasic® DSP-based echo cancellation module. It supports T1, E1, and J1 environments and is selectable on a per-card or per-port basis. The Octasic® DSP-based EC module enables users to eliminate echo tails up to 128ms or 1024 taps across all 256 channels in E1 mode or 192 channels in T1/J1 modes. Furthermore, this module takes advantage of the Octasic® Voice Quality Enhancement to provide superior sound quality on all calls. D830P/DE830P supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported.
D830E/DE830E works with Asterisk®, Elastix®, FreeSWITCH™, PBX in a Flash, trixbox®, Yate™ and IPPBX/IVR projects as well as other Open Source and proprietary PBX, Switch, IVR, and VoIP gateway applications. RoHS compliant Certificates: CE and FCC
- Voice-over Internet Protocol (VoIP) Services
- Complex IVR Trees
- "Meet-Me" Bridge Conferencing
- Calling Card Platforms
- VoIP Gateways (support SIP, H.323, and IAX)
- Legacy PBX/IVR Services
- Voice/Data Router (replace expensive routers)
- PRI/Switch Compatibility-Network or CPE
Chapter 2 Hardware Setup
...
- The computers that have D830E/DE830E card installed must comply with the country’s specific safety regulations.
- Only service personnel should go to install D830E/DE830E card.
- Before installing D830E/DE830E card, please unplug the power cord and remove the cover from your PC.
- For avoiding personal injuries and damages to your machine and D830E/DE830E card, make sure bracket of the card is secured to the PC’s chassis ground by fastening the card with a screw.
- Electrical Surges, ESD are very destructive to the equipment. To avoid it, make sure there is a low impedance discharge path from your computer to chassis ground.
- To reduce the risk of damage or injury, please follow all steps or procedures as instructed.

Chapter 2 Hardware Setup
There are some points that should be paid attention to when set up D830P/DE830P.
...
A part of system.conf which is one of the basic channel configuration files is displayed.
2. Country mode modification
...
Additional function
Users should run command "cat /proc/interrupts" to check D830P/DE830P has independent interrupt. If it shares interrupt with other device, it may cause some problems even cannot work normally. While D830P/DE830P allows users to modify interrupt pin during firmware upgrade for avoiding conflict. Or you can see if the EC module is working as follows:
