Cisco Systems 1900 Series Manual De Usuario

The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. 
Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end 
of the cable.

For connection to a modem, your router is provided with an RJ-45-to-DB-9 cable and a DB-9-to-DB-25 
adapter.

For detailed information about connecting devices to the auxiliary port, see the 

For cable and port pinouts, refer to 

When setting up your router, consider distance limitations and potential electromagnetic interference 
(EMI) as defined by the applicable local and international regulations.

The following sections describe network connection considerations for several types of network 
interfaces:

The IEEE has established Ethernet as standard IEEE 802.3. The Cisco 1941 Ethernet implementations 
are as follows:

1000BASE-T—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded 
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).

100BASE-T—100 Mb/s full-duplex transmission over a Category 5 or better unshielded 
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).

10BASE-T—10 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair 
(UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
