However, users can adopt RC802-30B series E1 fiber optic modem, which will convert the optical signals to G.703 compliant E1 electrical signals, and then, connect with a V.35 to fractional E1 interface converter. Users can adopt Raisecom series interface converters such as RC903-V35FE1 and RC904-V35FE1, and also other brand name interface converters. -

In the extended connection solutions in Chapter 2.3, if errors occur at the remote transmit and receive link, then LAL and RAL can be used to indicate this alarm. If users do not adopt Raisecom V.35 to fractional E1 interface converter (i.e. RC903-V35FE1), then the RAL indicator is invalid. -
Page 11: Fiber Optic Interface
Raisecom Technology Co., Ltd. http://www.raisecom.com 3.1.3 Fiber Optic Interface For the dual-strand models, the fiber optic interface is DSC/PC. TX stands for optical signal output (transmit); RX stands for optical signal input (receive). 3.2 Dip-switch SW1 Setup on the Bottom Panel The dip-switch SW1 on the bottom panel must be set up before use. - Page 12 Raisecom Technology Co., Ltd. http://www.raisecom.com 13×64K=832K 14×64K=896K 15×64K=960K 16×64K=1024K 17×64K=1088K 18×64K=1152K 19×64K=1216K 20×64K=1280K 21×64K=1344K 22×64K=1408K 23×64K=1472K 24×64K=1536K 25×64K=1600K 26×64K=1664K 27×64K=1728K 28×64K=1792K 29×64K=1856K 30×64K=1920K (Max bandwidth 1) 31×64K=1984K (Max bandwidth 2) In the above table, ‘1’ stands for OFF status of the switch, and ‘0’ stands for ON status. For example, the binary code corresponding to 384kbps bandwidth is ‘00110’.

If any of the three conditions cannot be met, then both modems shall be set to Master Control and the first 5 bits will be used to configure the actual bandwidth. Please note that when N=0, the equipment is working at transparent mode and this bit switch is invalid. - Page 14 Raisecom Technology Co., Ltd. http://www.raisecom.com Loop-back Normal Remote Positive Positive PCM31 Enable Loop-back Since the relationships between V.35 data and clock phase are different on different brand Routers, TX CLK and RX CLK phase options are used to solve the problem. When TX CLK and RX CLK are both set to Positive, the RC801-30B-FV35 modem has passed the test at the V.35 synchronous WAN interface of CISCO series Routers.

- Page 17 3． Cable loose. Compatibility with similar equipment of other brands Answer: Raisecom RC801-30B-FV35 cannot cooperate with similar products of other brands. It is because the signal coding and protocols at optical interface are different. However, users can refer to Chapter 2.3 for details of extended connection types.
