2-10 Router Installation and Configuration Guide
Preparing to Connect to a Network
Caution
The EIA/TIA-449 and V.35 interfaces support data rates up to 2.048 Mbps.
Exceeding this maximum could result in loss of data and is not recommended.
Signaling Standards
The synchronous serial port supports the following signaling standards: EIA/TIA-232,
EIA/TIA-449, V.35, X.21, and EIA-530. You can order a DB-60 shielded serial transition
cable that has the appropriate connector for the standard you specify. The router end of the
shielded serial transition cable has a DB-60 connector, which connects to the serial port on
the rear panel of the router. The other end of the serial transition cable is available with the
connector appropriate for the standard you specify. The documentation for the device you
want to connect should indicate the standard used for that device. The synchronous serial
port can be configured as DTE or DCE (except EIA-530, which is DTE only), depending
on the attached cable.
Note
All serial ports configured as DTE require external clocking from a CSU/DSU or
other DCE device.
Figure 2-1 shows the serial transition cables you can connect to the serial port on the rear
panel of the router.
