W A R N I N G

Preparing to Connect to a Network

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

The serial, console, and auxiliary ports contain safety extra-low voltage (SELV) circuits. BRI circuits are treated like telephone-network voltage (TNV) circuits. Avoid connecting SELV circuits to TNV circuits.

2-2

W A R N I N G

Installing the HP AdvanceStack Internet Router

Preparing to Connect to a Network

ISDN Connections

Use a BRI cable to connect the router directly to an ISDN. (See table 2-1.)

Network hazardous voltages are present in the BRI cable. If you detach the BRI cable, detach the end away from the router to avoid possible electric shock. Network hazardous voltages are also present on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned OFF.

The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by nonremovable, connect-one-time-only lug) must be made only by PTO staff or suitably trained engineers.

Table 2-1 lists the specifications for ISDN BRI Cables. Refer to the section “ISDN BRI Port and Cable Pinouts” in appendix A, “Cable Specifications” for pinouts.

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 2-2 to help you select the proper device type.

Table 2-2. Typical DTE and DCE Devices

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.

Signaling Standards Supported

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 from HP 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 DB-60 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. To order a shielded serial transition cable, refer to the section “Ordering Information” in chapter 1 “HP AdvanceStack Internet Router Overview” and appendix A, “Cable Specifications”.

N O T E	All serial ports configured as DTE require external clocking from a CSU/DSU
	or other DCE device.
	Although attempting to manufacture your own serial cables is not recom-
	mended (because of the small size of the pins on the DB-60 serial connector),
	cable pinouts are provided in appendix A, “Cable Specifications”.

Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal degrades significantly or is completely lost.

Table 2-3 lists the maximum speeds and distances for EIA/TIA-232 signals. This signalling standard supports unbalanced circuits at signal speeds up to 64 Kbps.

Table 2-3. EIA/TIA-232 Speed and Distance Limitations

Data Rate (Baud)	Distance (Feet)	Distance (Meters)
2400	200	60
4800	100	30

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than the EIA/TIA-232 signals. Table 2-4 lists the maximum speeds and distances for EIA/TIA-449, which are also valid for V.35, X.21, and EIA-530 signals.

Table 2-4. EIA/TIA-449, V.35, X.21, and EIA-530 Speed and Distance Limitations

Data Rate (Baud)	Distance (Feet)	Distance (Meters)

19200	513	156
38400	256	78
56000	102	31
154400 (T1)	50	15

C A U T I O N	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.

Console and Auxiliary Port Considerations

All router models include an asynchronous serial console and auxiliary port. The console and auxiliary ports provide access to the router either locally (with a console terminal) or remotely (with a modem). This section discusses important cabling information to consider before connecting a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port or modem to the auxiliary port.

The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control and the console port does not. Flow control paces the transmission of data between sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, a signal is sent to the sending device to suspend transmission until the data in the buffers has been processed. Because the auxiliary port supports flow control, it is ideally suited for use with the highspeed transmissions of a modem. Console terminals transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

Preparing to Connect to a Network

Console Port Connections

The router includes an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable. Your router comes with cables and adapters to connect a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port. To connect an ASCII terminal to the console port, use the RJ-45 roll-over cable with the female RJ-45-to-DB25 adapter (labeled Terminal). To connect a PC running terminal emulation software to the console port, use the RJ-45 roll-over cable with the female RJ-45-to-DB-9 adapter (labeled Terminal). The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The console port does not support hardware flow control. For detailed information about installing a console terminal, see the section “Connecting the Console Terminal and Modem” later in this chapter. See appendix A, “Cable Specifications” for cable and port pinouts.

Auxiliary Port Connections

The router includes 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. Your router includes a cable and an adapter to connect a modem to the auxiliary port. To connect a modem to the auxiliary port, use the RJ-45 roll-over cable with the male RJ-45-to-DB-25 adapter (labeled Modem). For detailed information about connecting devices to the auxiliary port, see the section, “Connecting the Console Terminal and Modem” later in this chapter. See appendix A, “Cable Specifications” for cable and port pinouts.
