Chapter 1 Overview
The router series supports hot swapping. Thus, you can remove or install FICs when
the router is running without disconnecting the power supply. But before that, you must
first execute the remove slot command; otherwise, unknown errors might occur. When
you replace the removed FICs, you do not need to execute the undo remove slot
command however.
If you execute the remove slot command inadvertently, you can cancel that operation
by using the undo remove slot command.

2.2 Router 1-Port Serial SIC
2.2.1 Introduction
1-port multiprotocol synchronous/asynchronous serial interface card (Router 1-Port
Serial SIC) supports both synchronous and asynchronous operating modes. It
supports:
zTransmission/Receiving and handling of synchronous and asynchronous serial
data streams;
zDifferent operating modes, such as V.24/V.35 and DTE/DCE, depending on the
actual applications;
z Automatic external cable type detection without the need of manual configuration;
z Local loopback and remote loopback, facilitating fault test and location.
I. Synchronous and asynchronous
In different operating modes, a synchronous/asynchronous serial interface supports
different signal standards and baud rates and the maximum transmission distance of
the signals is related to the baud rate setting. For the relationships between cable type,
baud rate setting and signal transmission distance, see the following table.

3Com Router 5000 and Router 6000 v2.41
Module Guide
Caution:
The baud rate cannot exceed 64 kbps if V.24 cable is used and the interface operates in synchronous
mode.
II. DTE and DCE
The synchronous serial interface supports both DTE (Data Terminal Equipment) and
DCE (Data Circuit-terminating Equipment) operating modes. Given that two devices
are directly connected, if one operates in the DTE mode, the other will operate in the
DCE mode. The DCE device provides the synchronous clock and specifies the
communicating rate. The DTE device receives the synchronous clock and
communicates at the specified rate. Generally, the Router is used as a DTE device. To
make sure that the device is a DTE or DCE, refer to the manual shipped with this
device. In addition, the following table may also help you to identify the type of the
device.
Chapter 2 Smart Interface Cards
Table 2-4 Typical DTE and DCE equipment
Equipment type Interface type Typical equipment
DTE Male PC, Router
DCE Female Modem, Multiplexer, CSU/DSU
Asynchronous serial interface is generally used as dialing port and connected to a
modem or a Terminal Adapter (TA). In this case, regardless of the operating mode of
the device, only an appropriate baud rate for the interface needs to be selected.
Synchronous serial interface is generally used for the direct connection to such a
device as DDN, frame relay, or X.25 switch.

Caution:
The relevant cables have been included in the standard configurations of Router 2-Port ISDN-S/T SIC
and Router 2-Port ISDN-U SIC.
2.3.6 Connecting Interface Cable
Caution:
z You should connect a cable to the port with the correct mark. Misplugging is prone to impair the
SIC/MIM and even damage the router.
z When using a telephone cable with ferrite core outdoors, you are recommended to install a special
lightning arrester on the input end of the cable in order to avoid lightning more effectively.
Chapter 2 Smart Interface Cards
If the SIC has been properly installed, follow these steps to connect the cable:
Step 1: Confirm the type of the ISDN line provided by your telecom service provider;
Step 2: Connect the cable;
zFor Router 2-Port ISDN-S/T SIC
If the ISDN U interface is adopted for the line, use NT1 for conversion. The connecting
procedure is to insert one end of the telephone cable with ferrite core into the BRI S/T
interface of Router 2-Port ISDN-S/T SIC and the other end into the NT1.
If the line uses the ISDN S/T interface, directly insert the cable with ferrite core into the
BRI S/T interface of the Router 2-Port ISDN-S/T SIC and the other end into the ISDN
S/T interface.
zFor Router 2-Port ISDN-U SIC
If the ISDN U interface is adopted for the line, directly insert the cable with ferrite core
into the BRI U interface of the Router 2-Port ISDN-U SIC and the other end into the
ISDN U interface.
If the line uses the ISDN S/T interface, contact the agent and replace the SIC with
