The 4-wire Channel Service Unit/Data Service Unit (CSU/DSU) module uses a standard straight-through RJ-45 cable to connect from the RJ-48S jack on the CSU/DSU to the wall jack.
This connection requires a straight-through RJ-48S-to-RJ-48S or a straight-through RJ-48C-to-RJ-48C cable.
Follow these steps:
Verify that the router is OFF.
Connect one end of the cable to the card's 56/64 kbps port.
Connect the other end of the cable to the 56/64 kbps services wall jack.
The table below shows the different LEDs on the card and their meaning.
|56/64 Kbps WAN Interface Card LEDs|
|TD||Data is being transmitted to the Data Terminal Equipment (DTE) interface.|
|RD||Data is being received from the DTE interface.|
|LP||The internal DSU/CSU is in loopback mode. Solid illumination any time a loopback is active.|
|AL||One of these alarm conditions is present: no receive signal, loss of frame signal from the remote station, or out of service signal from the remote station. This LED is off during normal operation.|
|CD||The internal DSU/CSU in the WAN interface card is communicating with another DSU/CSU.|
