Bottom View E1 port Setup Switch, from top to button is 1-8 bits Right is ON left is OFF. It is needed to set up the Ethernet port working status of connected switches, hubs, or NICs according to following table: Switch Setup of Local Actual Working Port of Remote-site Equipment... - Page 8 OFF= No loop back. When equipment is working in normal status, it should be OFF. This bit of dip-switch can be set to test link status only when the equipment works in master clock mode and on fractional E1 pattern. Whether the remote-site loop-back is successful or not is judged by the RLP yellow indicator on the front panel (On).

- Page 12 Chapter 3 Equipment Connection Make sure E1 link cable matches the connected equipment. If the equipment connected with RC interface converters in E1 link are comprised of such equipment as PDH, SDH, etc., please refer to the manuals of these equipment for the type, definition and line impedance of E1 interfaces.
- Page 13 Notice: When connecting the twisted pair cables, TD and TD should be twisted as a pair, and RD and RD too. V. RC905 Ethernet to E1 interface converters should be utilized in pairs in point to point mode. It cannot be interconnected with third party Ethernet to E1 interface converters.

Chapter 4 Troubleshooting If there is any problem during installation and application please try to solve it according to the following suggestions. If it is not solved yet, please contact technical staff for support. Power indicator PWR is OFF There is fault with power supply system. Ethernet link indicator LNK is OFF Check whether the network cable is disconnected. - Page 15 If the E1 link is provided by other equipment, within the first several minutes after the power supply is applied, LER alarm indicator may be flashing, and this is in normal status. Please wait for a while, the alarm will gradually disappear. If LER is flashing for a very long time, the link is in abnormal status.
