5. Installation & Preparation

5.1. Before installation

 Please make sure that your V.35 cable matches the equipment you want to connect

 Please check whether the equipment has been destroyed

 If you do not use network management, please configure the device through

DIP-switch before installation.

5.2. Cautions before Applying the Power Supply

 It is strictly forbidden to hot-swap the V.35 interface cable.

 If adopts the DC –48V power supply, please firstly connect the Protecting Ground (the

middle pin PGND). They must not be reversely connected, connect -48V with low

voltage input, BGND with high voltage input.

5.3. Equipment Deployment

 Keep the center office clean

 The deployment and settlement should be in order.

 Configure the clock mode, time slot, master/slave setting and other parameters

according to the specific connection type.

5.4. Connection Diagnoses

 Check whether there is any alarm on local equipment

 Test whether data communication can be performed between local DTE and remote

equipment

If the test is failed, please try the following steps.

1. Local bidirectional loopback test. Refer to previous dip-switch setup for configuration

details or configure by software. If the Router indicates loopback successful, the V.35

interface is working in good condition. If the Router indicates loopback fails, please

firstly check the timing resource and bandwidth setup at local site, and then 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.
