Switch Set S1, S1 Summary Table | Patton electronic 2703 guide

3.1.1 Switch Set S1

The configuration switches on S1 set clocking, rate adaptation, loopback enable, data invert, and interface (see also Switch S2). The default settings are summarized in table below.

S1 SUMMARY TABLE

Position	Function	Factory Default

S1-1	X.21/V.35	Off	V.35

S1-2	Reserved	Off

S1-3	Reserved	Off

S1-4	Rate Adaptation	Off	} 2.048 Mbps
S1-5	Rate Adaptation	Off	} 2.048 Mbps

S1-6	Data Inversion	Off	Not Inverted

S1-7	Clock Master/Slave	Off	Slave

S1-8	Test Enable	Off	Front Panel

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.

S1-1	Setting
Off	V.35 Interface
On	X.21/EIA-530 (RS-422) Interface

S1-2 and S1-3:Reserved for Future Use

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.

S1-4	S1-5	Setting
Off	Off	2.048	Mbps
On	Off	1.024	Mbps*
Off	On	512 kbps*
On	On	256 kbps*

*NOTE: Revision C. Firmware (or newer, Implemented 6/19/98) has been adopted to correct signal polarity at 1.024 Mbps, 512 kbps, and 256kbps. To operate Revision. C Firmware units with Revision B. (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.

S1-6	Setting
On	Data inverted
Off	Data not inverted

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.

S1-7	Setting
On	Model 2703 is master
Off	Model 2703 is slave, (clock is recovered
	from the network)
