Page 11: Settings Of Sw
FE1/V.35 Interface Converter set as External clock. Phase setting(SW-3) Bit 3 of SW in rear panel is used to set V.35 data phase. FE1/V.35 Interface Converter can auto detect the phase of receiving data. The phase of transmittal data can be set by this switch. Defied as below:... - Page 12 Definition Specification Default sample when rising SW-3 Phase setting of transmittal V.35 data OFF: sample when falling Table 9. Phase setting of transmittal V.35 data LOOP Setting (SW-4, SW-5, SW-6) BIT4, BIT5, BIT6 of SW (SW-4, SW-5, SW-6) are LOOP Setting, REM only can used in framed E1, defined as below: DEFINITION SPECIFICATION...

Page 15: Chapter 3 Installation
Check the power collocation of FE1/V.35 interface converter, if it is DC model, please pay attention to the voltage value and polarity, then connect the power supply referring to this manual. - Page 16 device may be caused permanent damages. The device has already adjusted optimal status before leaving factory, please don’t take apart the device privately if non technicians of our company. When the device has failure, you can make sure the failure range through self-loop function with the device, and contract with technical service center of our company in time.

Page 17: Chapter 4 Troubleshooting
Chapter 4 Troubleshooting Normal working status: when FE1/V.35 interface converter works normally, PWR (Green) indicator is bright, TXD (Yellow)、 RXD (Yellow) indicators are blinking, the others are off. When the device has failure, firstly make sure the failure range according to the status of the indicators, then deal with the problem. - Page 18 Please pay attention to the clock association when FE1/V.35 interface converter connect to DCE device via crossover cable, if DCE device is set to internal clock, then FE1/V.35 interface converter should be set to external clock; if DCE device is set to external clock, then FE1/V.35 interface converter should be set to internal clock.
