The Cisco T1 DSU/CSU WAN interface card is an integrated, fully managed Data Service Unit/Channel Service Unit (DSU/CSU) for T1 or fractional T1 service. It is supported on the Cisco 1600, 1720, 2600, and 3600 Series Routers, and it provides a cost-effective router-DSU/CSU combination with the following features:
T1 or fractional T1 network interface
N X 64 kbps or N X 56 kbps non-channelized data rates (N = 1 to 24)
Standards-based, including ANSI T1.403 and AT&T Publication 62411
This card requires an RJ-45 to RJ-45 straight-through cable (provided by customer).
The following table provides the pinouts for T1/E1 trunk and digital voice ports (RJ-48).
1Any pin not referenced on a connector is not connected.
The table below provides the specifications for the T1/FT1 LEDs and the loopback button.
|LP||Yellow||Line or loopback state is detected or is manually set by the user.|
|AL||Red||No receive signal|
|Yellow||Remote station has an alarm condition.|
|Blue||The remote station is probably out of service. If the remote station is an IOS-based router, its interface may be shut down.|
|CD||Green||The internal DSU/CSU in the WAN interface card is communicating with another DSU/CSU. This LED is on during normal operation.|
|Loopback button||--||Push this button to put the WAN interface card into loopback mode. The service provider can send a signal to test the connection from your site to the central office switch. Push this button again to turn loopback mode off.|
