USER’S GUIDE

calls. The system will not accept or make a call when the added bandwidth will exceed the configured maximum. The value is configured as a number from 2,400 bps to 3,072,000 bps. You may configure any value in this range. For example, if you have configured the base data rate at 64,000 bps, and the maximum data rate at 512,000 bps, the system would use a maximum of eight calls (connections) running in parallel to open up bandwidth (512,000 / 64,000 = 8). The value need not be a multiple of the Base Data Rate. The default configuration for the maximum data rate is 128,000 bps.

Note: A condition may occur in which the number of connections has reached the point where the maximum data rate will be exceeded with the next additional connection, and yet the remote device may initiate another call to the system. This inbound call causes the maximum data rate to be exceeded and the system will drop a connection. If the remote device is auto-dialing, this flip-flop condition will continue until you manually correct the problem. To correct this problem, configure the Throughput Monitor information to be identical on the CyberSWITCH and the remote device, or disable Throughput Monitoring on one of the devices. The Internet Engineering Task Force (IETF) is working on a standard solution to this problem.

If you are using multiple connections running in parallel (i.e., to the same device), the maximum number of connections that can be aggregated is 32. For maximum performance, however, we recommend aggregating no more than eight connections at a time.

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.
