CONFIGURING DEVICE LEVEL DATABASES

On-node Device Entries

DIAL-OUT PHONE NUMBER(S)

This configuration element is required when the Dial-Out feature is used. The dial-out capability allows the CyberSWITCH to initiate connections to PPP or HDLC devices located at remote sites. A phone number must be defined for each remote device that will be dialed. This number includes any prefix digits, area codes, or extensions as required to dial the destination device. It is possible to specify eight phone numbers for the remote device.

The system dynamically controls the bandwidth in use between the system and other devices. This is accomplished by establishing and disconnecting up to 8 calls to a single remote site over the digital network. The system monitors the connections for utilization and will add and remove connections based on the device configurable parameters described above (Base Data Rate, Initial Data Rate, and Maximum Data Rate).

SUBADDRESS

The Subaddress is used by a CyberSWITCH when it attempts to make a connection to a remote device. A Subaddress allows the device to share a telephone number with other devices and yet still recognize calls destined for it.

PROFILE NAME

The device profile identifies which line or lines are reserved for a particular profile, which in turn are reserved for a particular device(s). The feature that uses this configuration element, Bandwidth Reservation, is described in detail, in the Configuring Call Control chapter.

H0 CALL SUPPORT

If enabled, provides support for ISDN H0 calls operating at 384 Kbps. This provides one full 384 Kbps channel through the ISDN network and reduces the overhead associated with aggregating multiple channels. It is also almost always less expensive than the equivalent six 64 Kbps calls.

Not all ISDN networks provide support for H0 calls. This is dependent upon the ISDN service provider as well as the switch manufacturer.

FRAME RELAY ACCESS CONFIGURATION ELEMENTS

Note: These elements are configured for Frame Relay devices only.

PVC CONFIGURED

Information of the already configured frame relay virtual circuit which will be used for connections to the remote device. Currently, only permanent virtual circuits (PVCs) are provided by frame relay. If this information appears in a device entry, frame relay will be used first for the connection (regardless of any backup ISDN information configured).

X.25 ACCESS CONFIGURATION ELEMENTS

Note: These elements are configured for X.25 devices only.

VIRTUAL CIRCUITS

Specify an already-configured virtual circuit (either PVC or SVC) to be used for connections to this remote device. (Any two communicating X.25 devices must have a virtual circuit association between them before they can exchange data.)
