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.

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.

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
optical multiplexer
