Hardware Installation
If you are already familiar with OnSite device installation and configuration, this chapter will enable you to fin-
ish the job quickly. Installation consists of the following:
•
Preparing for the installation (see section “What you will need” )
•
Installing the T1/E1 WAN interface cable (see section “Interface cable installation” )
•
Installing the AC power cord (see section “Installing the AC power cord” on page 20)
•
Verifying that the unit will power up, and running a HyperTerminal session (see section “Logging onto the
OnSite device” on page 22)
•
Changing the IP address from the factory default setting (see section “IP address modification” on page 23)
•
Installing the Ethernet cable (see section “Installing the Ethernet cables” on page 23)
•
Launching a web browser in preparation for configuring the modem (see “Web Operation and Configura-
tion” on page 24)

Interface cable installation
The OnSite NTU comes with a selectable T1/E1 WAN interface (see figure 3 on page 20). Located on the
back of the OnSite device, the T1 and E1 interfaces are presented on an RJ-48C connector with selectable line
impedances of 100-ohms for T1 and 120-ohms for E1 lines (see
figure 4 ). The NTU also comes with dual
BNC for alternate connection to unbalanced 75-ohm E1 lines (see figure 3 on page 20).
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
