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.
