    Default Various questions concerning a public tender

    Good morning (afternoon),

    Introduction :

    The tender comprises everything, i.e intranet, PC's, optical fiber, VHF radio, telecom, call centers, video confernce, geolocasition,security, LAN, routers etc.

    My questions concerns the Telecom part.
    We have 3 levels of data transmission links and all in star configuation
    - 5 main level with connection to the regional levels
    - 6 regional levels with connection to the local levels
    - 37 local levels with connection to the unit levels

    Four types of IP-PBX - 20 users (1.373 x IP-PBX), 50 users (126 x IP-PBX), 100 users (20 x IP-PBX) and 200 users (90 x IP-PBX) with, each one, links to the public telecom company (RTC or ISDN for the small ones (20 users) and E1/PRI (MIC) for the bigger ones)

    Questions :
    1 - Each IP-PBX must be redondant which is not easy for the small ones even with SIP-TUNNEL
    2 - For the 100 users IP-PBX we need 2xE1 interfaces and for the 200 users IP-PBX 4xE1
    3 - For the 50 users 1xE1 and 20 users 4xFO's
    4 - Barge-in for all IP-PBX
    5 - Integration of data and video

    If you have any suggestions thank you.

    Nice weekend
