If you do not use network management, please configure the device through DIP-switch
be installation.
4.2. Cautions before Applying the Power Supply
z
It is strictly forbidden to hot-swap the V.35 interface cable.
z
If adopts the DC –48V power supply, please first connect the PGND (Protecting Ground
the middle pin). They must not be reversely connected, connect -48 with low voltage
input, BGND with high voltage input
4.3. Equipment deployment
z
In computer room and keep the room clean
z
Check the DIP-switch configuration other parameters again
4.4. Connection Diagnoses
z
Check if there is any alarm on local equipment
z
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.
5. F&Q
If there is any problem during installation and operation, please try the following solutions. If
the problems still cannot be solved, please contact distributors for technical support.
