To prevent this fault, the enterprise leases an ISDN line as a backup of the IP network. The ISDN line is used only when faults occur on the IP network. This improves communication reliability.Figure 2-13 Configuring link backup using the interface backup mode on an ISDN network...
A 64 kbit/s ISDN leased line is configured. To configure multiple 64 kbit/s ISDN leased lines, choose different number values and repeat step 9. For CE1/PRI interfaces, the number value ranges from 1 to 31. For CT1/PRI interfaces, the number value ranges from 1 to 24. Follow-up Proc...
a customer first rings the operator and provides the phone number of the other party. The operator then determines the line that goes either directly to the other party or to another operator along a path to the other party. In the latter case, the operators talk to each other, decide how...
An H channel for controlling the use of network is selected to effectively use lines when a request for H communication is issued. An ISDN line channel selection method, whereby a plurality of B channels are bundled and serve as an H channel, and the B channels are selected according to a...
As the number of VCs passing through the switch increases, the time taken to search the table goes up. This indicates a possible scalability issue: As the number of VCs increases, a switch may not be able to cope with cells arriving rapidly, because it does not have sufficient time to ...

In addition, the network terminator can perform a method which allows two digital communication devices coupled to one S-bus to share a communication session. In another embodiment, up to a six way conference call can be established with an analog telephone coupled to an ISDN network via the ...
your windows nt workstation computer has three modems installed. an isdn line with two b-channels and a dedicated phone line are attached to your computer. each b-channel has a separate telephone number. the ras server to which you plan to connect has fo
We use articles from arXiv, which only goes back to the year 1992. However, of course, the field of AI exists at least since the 1960s75. Thus, this raises the question whether the omission of the first 30–40 years of research has a crucial impact in the prediction task we formul...
There is also no switching of the line or any manual action needed. It has high installation and maintenance costs which tends to preclude its use for mid-security risks. This system also takes up space at the monitoring point, and can have an excessive cost in working hours particularly if...
