It is strictly forbidden to hot-swap the V.35 interface cable
Please read the user manual carefully.
Prepare all the wires and cables that are needed. Make sure there is no reverse connection,
disconnection or short circuit connection. Refer to Appendix A for details of cable making.
Make sure that the voltage of the power supply is within the tolerance range and the chassis is
grounded with the earth.
If you do not use network management, please configure the device through DIP-switch be installation.
Prepare the Bit Error Rate Tester and optical power test-meter for the test of link quality.
Fix the optical multiplexer into RC002-16 (19-inch 3U chassis). Pay attention to the ambience
requirement.
Installation
Check if there is any alarm on local equipment
Test if data communication can be performed between local DTE and remote equipment
If the test is failed, please try the following steps.
1.
Local bi-direction loop-back test. Refer to previous dip-switch setup for details. If the Router
indicates loop-back successful, the V.35 interface is working in good condition. If the Router indicates
loop-back fails, please first check the timing resource and bandwidth setup at local site, and try to
adjust the TX CLK and RX CLK phase option switch.
2.
If the E1 interface of remote equipment is connected with the ATM E1 interface, please make sure
that there is only on clock source in the network and the time slot configuration of both equipments is
the same
If the link still remains disconnected, please contact the technical support from the local distributors.
