तारांकन सर्वर अतिरेक को लागू करना

1. सर्वर, उबंटू 10.04 - 2 पीसी (रेजरियों के वर्तमान संस्करण के लिए, डिगियम बिल्कुल उबंटू 10.04 या सेंटी 5.6 का उपयोग करने की सलाह देता है)
2. Digium R850 - 1 पीसी।
3. Digium TE420 बोर्ड - 2 पीसी।
4. यूएसबी फ्लैश ड्राइव (न्यूनतम 1 जीबी) -2 पीसी।

1. हम मास्टर सर्वर बोर्ड में प्राथमिक ई 1 को जोड़ते हैं
2. हम सेकेंडरी E1 को स्लेव सर्वर बोर्ड से जोड़ते हैं
3. प्राथमिक USB मास्टर सर्वर के लिए
4. सेकेंडरी USB टू स्लेव सर्वर
5. USB कंसोल (वैकल्पिक)
