HOWTO Configure AddPac200E (Part1)

We have a pair of distant offices in 1500km. There is an iternet connection at each office. The office stuff spent enough money on the telephone calls to consider the construction the own system of voice transfer over IP. AddPac200E have been chosen for this purpose. AddPac site - {external link}, device description - {external link}.

AP200 Type - E

• 1-Port FXO Voice Interfaces for VoIP Service
• 1-Port FXS Voice Interfaces for VoIP Service
• 2-Port 10Mbps Ethernet Interface for LAN & WAN Interfaces
• 1-Port RS-232C Console Port

Here we have 2 LAN interfaces 10Mbps. , one of them Ether1.0 always looks to the local net, and the another one, Ether0.0, always looks to the internet or where we transfer he VOIP traffic. Also this router can work in NAT regime to make more secure the local users connection to the internet. Port FXS (Foreign Exchange Station) is the place where the telephone or fax set have to be plugged in. Port FXO (Foreign Exchange Office) - is the place where the PBX (private branch exchange) have to be plugged in.

So we need that at every office there will be the router with NAT, one direct phone (voice port 0/1 only), and the office PBX (voice port 0/0 only). It is very difficult to find the documentation regarding this question. At least I can’t. The standart producer manual have some certian errors. Also there is a Russian speaking forum {external link}.

Let us assemble the simpliest layout with a pair of AddPac200E, viz. pic. The task is to perform the minimalistic configuration of every device to make it visible each other as the network nodes at least. Unobvious notes: ether0.0 interface of the AddPac device usually looks to the outside world; through this interface there will be VOIP transferred. ETH0.0 interfaces of each AddPac device have to be connected by cross-over cabling. Ether0.1 interface usually defines for the local network purposes. Connect with the cord from AddPac set the console and your COM port, start Hyperterminal or sort of on 9600 8N1, hit twice or so the , get the invitation login, answer root, password router. Configure each device.

^Z - means the button combinaion -Z for rapid quiting from configuration regime. After all the deal you’ll see that your PC is able to ping eth0.0(LEFT_AP200E), eth1.0(LEFT_AP200E), eth0.0(RIGHT_AP200E), eth1.0(RIGHT_AP200E). Left AP200E pings eth0.0(RIGHT_AP200E), eth1.0(RIGHT_AP200E).
