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).

UBADDRESS

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.

ROFILE 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 C

ALL 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.

RAME RELAY ACCESS CONFIGURATION ELEMENTS

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

PVC C

ONFIGURED

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 A

CCESS CONFIGURATION ELEMENTS

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

IRTUAL 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.)
