• Three 2212s with AIS V3.3 and higher
• One 9783s with one HSP card
• Two FXS analog adapter cards
• Two analog telephones
• Two RJ11 cables
• Six serial cables (DTE-DCE and DTE-DCE)
4.2.4.2 Network Description
Figure 49 on page 106 shows the network diagram used in the lab to set up
back-to-back connections. If branch office Chiba wants to dial branch office
Yokohama, the voice setup message from 2212 Chiba goes through wan port 0
DLCI 16 and connects to 2212 Tokyo WAN port 3 DLCI 16. Since voice
forwarding is enabled on this interface, it forwards the setup message to the 9783
data port A2 DLCI 19. The IBM 9783 then routes the voice setup message to
2212 Yokohama through 2212 Tokyo using data port A2 DLCI 17. Then Tokyo
2212 forwards the voice setup message to 2212 Yokohama and the call is
established. So every time a call is made from branch office Chiba to branch
office Yokohama, the call is routed by the headquarters Tokyo IBM 9783 and vice
versa.
