1. Overview 1.1. Introduction RC802/804/806-30B-FV35 series modular are devices that are deployed to transmit V.35 signals on fiber optics. They are widely used equipment in constructing Wide Area Networks, and provide solutions for connecting Routers distantly. RC802/804/806-30B-FV35 is modular type device and can be installed in our company’s RC002-16, RC002-4 and RC001-1 chassis.

2. Parameters 2.1. V.35 Interface Specification Physical characteristics: Connector type: Working mode： Interface bit rate： Complies with V.35 interface standard of ITU HDB26 Female, transfer to ISO 2593 female connector by accessory cable CBL-V35-HDB26M/M34F DCE (support cross connection with other DCE device) V.35 interface bit rate is N×64Kbps（N=1~31）at E1 fractional mode V.35 interface bit rate is 2048Kbps at E1 transparent mode 2.2.
2.5. Structure character Dimension: 91*25*178 (W*H*D) (mm) 2.6.
3. How to Use 3.1. Description of the Front Panel V35 TX RX ALM PWR/ PAT Figure 1 the front panel of RC802/804/806-30B-FV35 module 3.1.1. Power Supply/Error code test Indicator PWR power supply indicator (green/yellow): PWR/PAT Green/Yellow: Green, built-in power works in good condition. Yellow, when using built-in error code test function, if the fiber interface receives its own sending pseudo random sequence data the indicator will be in steady yellow.
This left figure is HDB26 connector, and it can connect to ISO2593 connector by cable provided by Raisecom. This left figure is ISO2593 connector of standard V.35 interface. The connector used for this series device is DCE Connector Face – 34 Pin Female which can be connected to standard DTE cable.

OFF. That is to say there must be some timeslot is enabled. 3.2.2.
There is an error code test unit inside this series device, and the main purpose of this unit is that produces pseudo random sequence (2E15-1) and sends them to optical line. This sequence can be uploaded to proper data channel through configuration, then via many loop back mode the returned sequence is sent to device for testing. The testing result will be displayed by the PWR/PAT indicator on front panel. When error code is captured the PWR/PAT indicator turns to green and keep for at least one second.
DTE or Error code equipment V.35 Local (Master) Remote (Slave) Fiber DTE or Error code equipment Local loop back: it actually includes local two direction loop back. Those are internal loop back on V.35 interface and external loop back on fiber interface, as above figure. To perform local loop back test please set SW5-6 and SW5-7 as ON. The interface inquiry result of local and remote router is loop back if the fiber and V.35 cable is good. DTE or Error code equipment V.
OFF Disable When fault pass enable, alarms of optical interface Rx and Tx will be transferred to DCD and CTS signal on V.35 interface; When fault pass disable the DSR, DCD and CTS signals of V.35 interface will be valid. When fault pass enable, if the device has local alarm (errors on fiber Rx interface) the DCD signal of V.35 interface will close and DTE device should have some denotation. When fault pass enable, if the device has remote alarm (errors on fiber Tx interface) the CTS signal of V.
In “Master Clock-Slave Clock” topology, if DXC, MUX devices are in E1 link, the DXC, MUX and remote modem should all be slave clock mode (follow the clock of E1 link) Master Clock (Clock Source) Slave Clock Fiber RC802-30BFV35 RC801-30BFV35 V.35 DTE wire V.35 DTE wire Router Router 3.4.2. Point-to-point, ‘Terminal Clock – Slave Clock’ Topology When the remote DTE must follow the timing resource of local V.35 clock, that is to say the TX CLOCK of local TX is inner clock source.
slave clock mode. 4. Installation & preparation 4.1.
If you do not use network management, please configure the device through DIP-switch be installation. 4.2. Cautions before Applying the Power Supply It is strictly forbidden to hot-swap the V.35 interface cable. If adopts the DC –48V power supply, please first connect the PGND (Protecting Ground the middle pin). They must not be reversely connected, connect -48 with low voltage input, BGND with high voltage input 4.3.
properly. YELLOW steady on in unframed mode after connecting optic fiber Answer: in unframed mode there will be yellow steady on when optical interface receives AIS. If the line works normal, please check the following conditions: V35 interface of remote site device does not connect to router, remote router is powered off or V35 interface of remote router is shutdown. When work with few venders’ router, there maybe yellow steady on or interval on, but they can communicate with each other.
