1. The 1st and 2nd bit: Clock mode choosing dip-switch Timing1, Timing2 (default is OFF)

The Clock mode of device is defined by the 1st bit and 2nd bit of SW5, detail is shown in below table:

SW5-1 SW5-2 Clock Mode OFF OFF Master Clock (Internal clock) OFF ON ON OFF

V.35 terminal Clock ( Follow V.35 interface clock)

ON ON Slave Clock ( Follow fiber line clock)

2. The 3rd bit: Timeslot auto follow function TS_FLOW (default OFF)

SW5-3 Timeslot auto follow function

ON Enable

OFF Disable

To make local timeslot follow remote timeslot, below four conditions should be ensured:

(1) This series device is used point to point in pair. (2) There is no PCM device linked in E1 line. (3) Two end devices should not work in transparent mode. Firstly, the local device must be set to fractional mode. (The SW1-1 is ON and TS1 to TS31 should not be all OFF) (4) When local device works on slave clock mode the timeslot auto-follow function will be enabled automatically.

When all of above condition is satisfied, set the SW5-3 of local device as ON to open timeslot auto-follow function, the timeslot and frame mode (PCM30/PCM31) of local device will follow the configurations of remote device automatically.

3. The 4th bit: Error code test function choosing dip-switch BERT (default OFF)

SW5-4 Internal Error Code Test Function

ON Enable

OFF Disable

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. If there is no new error code occur the PWR/PAT indicator will come back to steady yellow status.

The device will add test sequence to user data channel after the error code test function is enabled. This function is available in fractional mode and unframed (transparent) mode, and when it is enabled the V.35 operation will intermit.

Notice: The error code test function can be operated with many loop back test. When the local dual-direction loop back function is disable the loop back can be realized by fiber, but the dual-fiber S3 and all single fiber are forbidden. At the time when PWR/PAT indicator is steady yellow it indicates that correct test code was received. If the remote dual-direction loop back is enabled accompanied with error code test, it means the whole information process will be tested.

4. The 5

bit: RC CLK Phase choosing dip-switch (default OFF)

SW5-5 Phase Choosing

ON RX CLK Reverse Phase

OFF RX CLK Positive Phase

The RX CLK phase choosing is provided according to the different V.35 clock and data phase of different brand router. On Cisco series router the test result of V.35 synchronization WAN interface is passing when this device is connected and its RX CLK is Positive.

RX CLK is Positive: Data will be sent to RD signal during RX CLK falling edge.

RX CLK

RX CLK is Reverse: Data will be sent to RD signal during RX CLK rising edge.

3.4. Basic Connection Type

The connection topologies introduced in this part is only for user reference. Users are advised to design and deploy the most appropriate topology according to their specific environment.

3.4.1. Point-to-point, ‘Master Clock – Slave Clock’ Topology

When connecting Routers or other V.35 interface equipment point to point, routers should work in DTE mode. For the convenience of installation and test, it is advised to set the local modem ‘Master Clock Mode’, and remote modem ‘Slave Clock Mode’. That is, the timing resource is from the local modem.

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)

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. In this condition, it is advised to set the local modem ‘Terminal Clock Mode’, and remote modem ‘Slave Clock Mode’. In (Terminal 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).

z 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. It is because remote router will send AIS when there is no data transporting.

z Enable loop back function, use the inner error code tester and power on, but the

status of PWR/PAT is not stable.

Answer: first make sure that the connection of optical interface is normal and there is no error code, and then make sure there is no loop back configuration on remote site equipment. In the first 15 seconds after being powered on, the local and remote equipments will change information with each other, it is normal. Please wait for some moments and then judge error code status according to PWR/PAT indicator.

z PRI of network management and DIP-switch

Answer: CPU will read the DIP-switch configuration once it is powered on, and then network management has higher privilege. (Notice that network management cannot configure Fault-Pass-Through function)

z Severe Packet Loss

Answer: this may be caused by the following conditions: There is more than one clock source in the network; Check the status of router’s V35 interface, if there is RX/TX data error, please adjust RX CLK phase of local and remote device.

z Compatibility

Answer: the optic interface of this equipment deploys PDH technology, and can only communicate with Raisecom RC800 series optical multiplexer. If the remote site is RC800-30B series single E1 multiplexer, the E1 interface can communicate with all the other venders’ equipments.

z Compatibility of V35 interface

Answer: RC800-30B-FV35 series can work with other Raisecom V35 equipments, and can provide a flexible network topology, including:

 Standalone RC903-V35FE1 V35 to fractional E1 interface converter  Modular RC904-V35FE1 V35 to fractional E1 interface converter  SUBM-FV35 (N×64K V.35) which is installed in extension slot of some Raisecom
