USER’S GUIDE

194 CyberSWITCH

X.121 ADDRESS

If you choose an SVC for your virtual circuit, you must provide the X.121 address of the remote

device you are currently adding to the Device Table. (The X.121 addresses for both local and remote

devices are provided by your X.25 provider.)

IGITAL MODEM CONFIGURATION ELEMENTS

Note: These elements are configured for digital modem devices only.

INE PROTOCOL

The available line protocols for ISDN access devices. The only available selection at this time is PPP.

AUD RATE

The baud rate at which data will be transmitted. The only selection at this time is Auto, which

implies the CyberSWITCH and remote modem will negotiate the baud rate automatically.

EARER CAPABILITIES

The information transfer capabilities that are used for digitized analog modem signals. Choices are:

Speech or 3.1 kHz Audio. The default value is Speech.

IAL OUT PHONE NUMBER

The phone number the CyberSWITCH will use to call out to this device.

UTHENTICATION CONFIGURATION ELEMENTS

PAP PASSWORD

This password is used by PPP line protocol for PAP authentication. This is an unencrypted

password value (a string of 1 to 12 ASCII characters) used as a security check when PAP Password

Security is enabled. (PAP is an authentication protocol defined in RFC 1334 as part of the PPP

protocol suite.) At connection establishment time, the calling party sends an unencrypted device

identifier and password combination over the WAN to the system. The system looks up the Device

Name based on the received device identifier and validates the password for that device. If the

password received matches the password configured for the identified device, the call is accepted.

Otherwise, the call is disconnected.

This value is stored in the same location as the bridge password, so a change to one password

affects the other.

CHAP S

ECRET

This field is used by PPP line protocol for CHAP authentication. This is a string of 1 to 17 ASCII

characters that is used as a security check when CHAP Challenge Security is enabled. (CHAP is an

authentication protocol defined in RFC 1334 as part of the PPP protocol suite.) CHAP is

characterized by a highly secure challenge and response mechanism which is performed at

connection setup, and which can optionally be repeated throughout the existence of the connection.

A shared CHAP Secret is configured for the devices at both ends of the connection. Refer to System

Information, system secret. As opposed to a password, a CHAP Secret is not sent across the link, and

therefore is not susceptible to interception. Instead, a calculation is done on the packets transmitted

between the two devices, and the results are compared to the shared CHAP Secret for validation.

If the calculation’s results do not match the expected results, the connection is terminated.
