2.4 Connecting to the telephony devices
The VOI-8000 supports three types of TIM. One is FXO, FXS and the other is E&M. Each
module has four ports for connecting to telephony devices.
The FXO module is designed for connecting to PBXs or central office switches.
The FXS module is designed for connecting to analog telephone sets or G3 fax machines.
Connecting the telephony devices to the appropriate RJ11 ports on the TIM.
The E&M module is designed for connecting to equipment (such as PBX or channel bank)
providing the tie-line connection. Connecting the tie-line port to the appropriate RJ45 port on
the TIM.
Warning: connection of incorrect telephony devices to the ports on the TIM can cause
permanent damage to the TIM and/or the VOI-8000
.
2.5 Connecting to the Network
The RJ45 network port on the front panel supports 10/100 Mbps half-duplex connection to
Ethernet. You can use either Category 3 or 5 straight-through UTP cable for 10 Mbps
connection, but use Category 5 for 100 Mbps connection. To connect to Ethernet, insert one
end of the Ethernet cable to the RJ45 port on the front panel of the VOI-8000 and other end
of the cable to an Ethernet switching hub or repeater hub.
2.6 Providing Power to the VOI-8000
To provide AC power to the VOI-8000 complete the following steps:
1. Turn the power switch on the rear panel of the VOI-8000 to the off position.
2. Connect one end of the power cord that came with the VOI-8000 to the power
receptacle on the rear panel.
3. Connect the other end of the power cord to an AC power outlet.
4. Turn the power switch on. The VOI-8000 will perform power on self-test. After
completing the self-test, the SYSTEM LED blinks continuously and the TIM indicators
on the front panel will turn on.
2.7 Assigning IP address to the VOI-8000
The IP address is the unique logical address identifying each IP node, such as the VOI-8000,
on an IP network. An IP address is a 32-bit number expressed as four decimal numbers from
0 to 255 separated by periods. The VOI-8000 needs static IP address and be aware of the
subnet mask and default gateway (typically a router) of your network to be able to send to
and receive data from the IP network. Consult your network manager to obtain a unique and
static IP address for the VOI-8000, the IP subnet mask and default gateway of your network,
and fill out the work sheet in Appendix A before configuring the gateway. Procedures for
assigning IP address, default gateway and subnet mask is available in Chapter 4.
