Switch S1-1: Terminal Interface (Works in Conjunction with Switch S2)

Set Switch S1-1 (as well as S2-1 and S2-2)to determine whether the signals passed between the Model 2703 and the terminal device will follow the EIA-530 (RS-422), CCITT X.21 or CCITT V.35 standard. If S2-1 and S2-2 are set for “EIA-530/X.21,” then the setting for S1-1 determines which of those two interfaces is selected. Note: If S2-1 and S2-2 are set for “V.35,” switch S1-1 must be set to “off.” Regardless of the pin-out standard chosen, the physical connector is a female UD-26.

Switches S1-4 and S1-5: Rate Adaptation

Set Switches S1-4 and S1-5 together to allow the Model 2703 to adapt to terminal devices that run at data rates less than 2.048 Mbps (The network rate remains 2.048 Mbps regardless of the terminal rate adaptation setting). The setting you select must match the data rate of your terminal device.

(or older) units at one of these sub-rates, you must invert the data (Switch S1-6 On. See Below) (Firmware revision level is printed on the label on the bottom of the unit).

Switch S1-6: Data Inversion

Set Switch S1-6 to determine whether or not the data stream from the local DTE is inverted within the Model 2703 before being passed to the G.703 network. You may need to invert the data stream when you use the Model 2703 with an imbedded G.703 device that inverts the data on the remote end. Normally, data inversion is not necessary.

Switch S1-7: Master/Slave Clock

Set Switch S1-7 to allow the Model 2703 to provide the master clock, or recover the clock from the G.703 network.
