5.0 INSTALLATION

Once the Model 2707/I is properly configured, it is ready to connect to the G.703 interface, to the Ethernet port, and to the power source. This section describes how to make these connections.

5.1 CONNECTING TO THE G.703 NETWORK AND ETHERNET LAN

This section describes installing the G.703 (75-ohm and 120-ohm), Ethernet LAN, and power connections (shown in Figure 4). Refer to the following to detemine which installation procedures you will use:

The 75-ohm dual-coax female BNCs (TXand RX) are used for con- necting to a 75-ohm dual coax G.703 network interface. If your G.703 network terminates via dual coaxial cables, refer to section “Connect- ing Dual Coaxial Cable (75 ohm) to the G.703 Network” on page 13

The 120-ohm RJ-48C jack is used for connecting to a 120-ohmtwisted-pair G.703 network interface. If your G.703 network terminates with a RJ-48C, refer to section “Connecting the Twisted Pair (120 ohm) to the G.703 Network” on page 14.

The Ethernet 10Base-T port is configured as DTE (Data Terminal Equipment). If the Model 2707/I is to connect to another DTE device such as a 10Base-T network interface card in a PC, refer to “Connect- ing the 10Base-T Ethernet port to a PC (DTE)” on page 14. Otherwise, refer to “Connecting the 10Base-T Ethernet Port to a Hub” on page 15.

Refer to “Power Connection” on page 15 to connect the Model 2707/I to a 100–240 VAC source or to a 36–60 VDC DC-to-DC adapter.
