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.
