The PC to CyberSWITCH Connection
USING AN AMP CONNECTION
If you want to use out-of-band management, want a replacement for a LAN connection, or want
local console access, you need an asynchronous management port (AMP) connection.
FOR OUT-OF-BAND MANAGEMENT
Out-of-band management allows you to manage the CyberSWITCH from some remote location
without making use of the LAN or WAN connections. Out-of-band refers to the fact that you are
not using normal data channels. The following graphic illustrates an out-of-band connection.
Connection instructions:
1. At the CyberSWITCH:
• complete your LAN and WAN (ISDN) connections
• using the
ampconf Manage Mode command, configure the CyberSWITCH for the modem
you will use
• connect a modem to the CyberSWITCH (using the Console connection)
• connect the modem to the analog line (use a standard PC modem RS232 cable for this, do
not use the supplied cable)
2. At the remote management site:
• connect the managing PC to a modem
• connect the modem to the analog line (use a standard PC modem RS232 cable for this, do
not use the supplied cable)
FOR LAN REPLACEMENT
There are two reasons for wanting a LAN replacement:
• to provide a connection to manage the CyberSWITCH without using a LAN connection, or
• no LAN connection is possible because your PC does not have a NIC card.
FOR LOCAL CONSOLE ACCESS
You may use the AMP connection for local console access. With this type of access allows you to
use a directly connected PC, monitor, and keyboard to manage your CyberSWITCH.

The ISDN Connection
THE ISDN CONNECTION
No matter which LAN connection method you use, you must have an ISDN connection. This
connection is your link to the outside world through ISDN lines. There is more than one ISDN
connection method possible. The method you use depends on the country you live in, and whether
or not you have an CyberSWITCH with the internal NT-1 option.
CYBERSWITCHSWITH INTERNAL NT-1S
For countries that require the customer to supply the NT-1s (for example, the United States), an
CyberSWITCH is available with an internal NT-1 option.

CYBERSWITCHSREQUIRING DSUS
For countries that require DSUs (for example, Japan), your CyberSWITCH will not have an internal
NT-1. You will need to use an external MJ and DSU in your connection to the network.
CONNECTION INSTRUCTIONS
1. If you are not using an CyberSWITCH with an internal NT-1:
a. Connect the CyberSWITCH to required intermediary devices (NT-1, or a MJ and CSU)
using a straight through cable (RJ45 connectors and twisted pair).
b. Connect the intermediary device to the network (for example, to your ISDN phone jack).
2. If you are using an CyberSWITCH with an internal NT-1, simply connect the CyberSWITCH to
the network using a straight through cable (RJ45 connectors with twisted pair).
TERMINATION SWITCHES
On the CyberSWITCH’s back panel(to theright of the BRI connector) there are a pairof termination
switches for multipoint connections. These switches are labeled Term. These DIP switches control
the terminating resistors for the Basic Rate Interface.
You must set both switches in the same direction or improper operation may result. The small
arrow points in the direction of the on position. When the switches are on, the resistors for the
connector are providing termination for the BRI line. Conversely, when the switches are off, the
resistors for the connector are not providing termination for the BRI line.
On an S/T interface, it is important to have the switches set correctly. On a U interface, the circuitry
is intended to operate properly no matter which switch setting is used; however, optimum
operation is achieved with the switches off.

THE POTS CONNECTION
The dual-line, Plain Old Telephone Service (POTS) feature allows one or both of the ISDN B-
channels to alternatively be used with traditional phone equipment (for example, a phone, a fax, or
an answering machine). When used with a LAN or AMP connection, this allows you to use one
ISDN line for both data and voice.
Note: The CyberSWITCH must have a power source for operation. Since POTS is an integral
feature of the CyberSWITCH, it too needs power. When power is off, you loose your
CyberSWITCH phone service. Therefore, do not rely on the phones connected to the
CyberSWITCH ports for emergency service (i.e., 911). In a home office or small office
situation, we recommend retaining a standard analog phone line for emergencies.
The POTS interface acts as a simple PBX or Key System. Note that the POTS interface responds to
DTMF (Dual Tone Multifrequency) signaling only; it does not support pulse dialing.
Use the following graphic and instructions to complete the connection.
1. Insert one end of a telephone line into Jack 1 (see above graphic).
2. Insert the other end of the line into your telephone equipment.
3. If you are connecting a second piece of telephone equipment, repeat the above steps using Jack
2.

B ASICS
Once your cabling is complete, power on the CyberSWITCH simply by plugging its power cord
into an electrical outlet. During the powering on sequence, the CyberSWITCH’s LED indicators
provide valuable information. We provide you with instructions for “reading” the LED indicators.
After powering on, but before putting the CyberSWITCH into normal operation, we recommend
that you read the Release Notes for important information.
READING THE LED INDICATORS
Refer to the following graphic for locating specific LED indicators:
During the CyberSWITCH’s power on sequence, you should see the following:
1. After plugging the CyberSWITCH in, the power indicator will light up and stay lit.
2. The service indicator will light up for the duration of the initialization tests. It will then blink if
there is a problem. For example, it will blink if your LAN is not properly terminated. For
further information, refer to Trouble Shooting.
3. The RX indicator blinks during port testing.
4. If you are using a 10BaseT connection, the 10BaseT indicator will light up if the connection is
good.
5. The SYNC indicator will light up if layer 1 comes up.
6. The D-CHAN indicator will light up if the data link comes up.
7. After power on is complete, check the log messages (issue the
dr console command) for any
warning or error messages.
