D IAL -O UT P HONE N UMBER ( 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).
S 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.
P ROFILE N AME
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 S UPPORT
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.
F RAME R ELAY A CCESS C ONFIGURATION E LEMENTS
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 C ONFIGURATION E LEMENTS
Note: These elements are configured for X.25 devices only.
V IRTUAL C IRCUITS
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.)
