4. Getting Started
This chapter describes how to connect the OmniConnect/ISDN series access devices to the
network. In addition, configuration and installation information for a Windows ‘95/NT-based
network is provided. Refer to the diagrams in this chapter and in the previous chapter to
identify the connectors used during installation. The section contains the following:
•
Required connectors, cables and hardware
•
ISDN port connection
•
Ethernet connection
•
Windows ‘95/NT network adapter installation and configuration
•
External telephone connection
•
Power connection
•
Serial console port connection
4.1. Required connectors, cables and hardware
All connectors on the OmniConnect series access devices are on the rear panel of the unit. It
is not normally necessary to connect the serial console port to the OmniConnect unless a
FLASH upgrade is required. The following items will be needed in order to connect the
OmniConnect/ISDN series access device to the network and an external telephone:
•
Power Supply
•
10Base-T Ethernet Cable (RJ-45)
•
ISDN Cable (RJ-45)
•
Telephone Cable (RJ-11)
•
OmniConnect/ISDN Series Internet access device
4.2. ISDN port connection
In North America, OmniConnect/ISDN accesses ISDN lines through a network termination
device (NT-1). The OmniConnect/ISDN (U) access device has a built-in NT-1 capability, so
you can connect this access device directly to the line. If an OmniConnect/ISDN (ST) access
device is being used in North America, then a connection must first be made to an external
NT-1 device and then from the NT-1 device to the ISDN line.
The diagrams below illustrate the connections for both the OmniConnect/ISDN (ST) access
device and the OmniConnect/ISDN (U) access device.
The OmniConnect/ISDN (U) is connected to the ISDN line using the supplied RJ-45 (8-pin)
to RJ-45 (8-pin) cable, as shown in Figure 3-1. It is also possible to use an RJ-11 to RJ-45
cable. The U interface on the OmniConnect access device may also use either an RJ-11 or RJ-
45 cable for connection to the ISDN network since only the middle two pins are being used.
The OmniConnect/ISDN (ST) access device is connected to the NT-1 device line using the
supplied RJ-45 (8-pin) to RJ-45 (8-pin) cable, as shown in Figure 3-2. For the connection
from the NT-1 device to the ISDN line, it is also possible to use an RJ-11 to RJ-45 or RJ-11 to
RJ-11 cable. The S/T interface on the OmniConnect/ISDN access device may also use an RJ-
11 connector since only the middle four pins of the jack are used. Using the
