The router ser ial interf ace connects to the W AN via a 2707/C (V .35) E1 NTU and to the remote 2707/I with suppor t for PPP bridging.
9 4.0 CONFIGURATION The Model 2707/I f eatures configuration capability via hardware DIP s witches. This section describes all possible DIP s witch configurations of the Model 2707/I. 4.1 DIP SWITCH CONFIGURATIONS The Model 2707/I has an internal DIP switch that enables configur ation f or a wide range of applications.
10 Switch S1 settings T able 1 sho ws the settings f or DIP s witch S1-1 thru S1-8. SW1-1 Line Coding: HDB3 (default) Use Switch SW1-1 to control the Network Line Coding options. Set these options to be the same as the Line Coding given to y ou by your Service Provider .
11 The receiver recogniz es these special violations and decodes them as zeros . This method enables the network to meet minimum pulse den- sity requirements. Unless AMI is required in your application, HDB3 should be used whene ver possib le. • AMI .
12 5.0 INSTALLATION Once the Model 2707/I is properly configured, it is ready to connect to the G.703 interf ace, to the Ethernet por t, 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.
13 Connecting Dual Coaxial Cable (75 ohm) to the G.703 Netw ork Ref er to Figure 5 to make the proper connections . Figure 5. Rear panel, showing location of connectors Note The outer conductor of the coax cables are isolated from system ear th ground.
14 Connecting the T wisted Pair (120 ohm) to the G.703 Network Ref er to the pinout and signals chart in Figure 6 to connect the 120-ohm G.703 network channel.
15 Figure 8. 10Base-T cross-ov er cable connection Connecting the 10Base-T Ethernet P or t to a Hub The 10Base-T interf ace is configured as DTE (data terminal equipment), just like a 10Base-T netw ork interface card in a PC . Theref ore, it “e xpects” to connect to a 10Base-T Hub using a straight-through RJ-45 cable .
16 DC Power . The 36-60 VDC DC to DC adapter is supplied with the DC version of the Model 2707/I. The black and red leads plug into a DC source (nominal 48VDC) and the barrel power connector plugs into the barrel power supply jac k on the 2707/I. (See Figure 10).
17 6.0 OPERATION When the Model 2707/I has been properly configured and installed, it should operate transparently . This section descr ibes power-up , LED sta- tus monitors, and the b uilt-in loopback test modes .
