OVERVIEW
An access defines the connection details the CyberSWITCH uses to reach the network. The default
access is ISDN access, a switched-network access. Configurable accesses are required for dedicated
network connections, for packet-switched network connections including X.25 and frame relay
connections. Refer to the information below for the alternate access you wish to add.
DEDICATED ACCESSES
CONFIGURING A DEDICATED ACCESS
USING CFGEDIT
1. Select Access from the Physical Resources menu, then follow the onscreen instructions to add a
dedicated access.
2. Select the line Id of the line you will use for this access.
3. For BRI and PRI lines: select the bearer channels the access will use.
4. Select the line protocol. In almost all cases, select PPP. Select HDLC only if you are connecting
to a device that uses HDLC over a dedicated access.
5. Enter the device name tied to this access (optional for accesses using PPP protocol, mandatory
for accesses using HDLC protocol).
Note: Device authentication must be enabled for dedicated accesses to properly identify the
remote device and provide switched backup and overflow to that device. Remote devices
using a dedicated connection must use PPP for device authentication. Authentication
configuration is described in Security Configuration.
