Preparing to Connect to a Network
Synchronous Serial Connections
Before you connect a device to the synchronous serial port, you will need to know the following:
■The type of device, DTE or DCE, you are connecting to the synchronous serial interface
■The type of connector, male or female, required to connect to the device.
■The signaling standard required by the device.
DTE or DCE
A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE device provides a clock signal that paces the communications between the devices and the router. A DTE device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation that came with the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper to select either mode.) If you cannot find the information in the documentation, refer to table
Device Type | Gender | Typical Devices |
|
|
|
DTE | Male1 | * Terminal |
|
| * PC |
DCE | Female2 | * Modem |
|
| * CSU/DSU3 |
|
| * Multiplexer |
1.If pins protrude from the base of the connector, the connector is male.
2.If the connector has holes to accept pins, the connector is female.
3.Channel service unit/data service unit.
