2. CBL-V35-HDB26M/M34M-X Cable making Instruction
This cable is cross connection cable which is used to link the V.35 (DCE) interface of node equipment as
DDN to the V.35 interface of the RC802-30B-FV35 series device. Using this cable if the clock resource is
provided by node equipment the RC802-30B-FV35 series device should be configured to V.35 terminal
mode. If the clock is provided by fiber-optic multiplexer the node equipment's clock should be slave
mode.
