  Amazon.com: Signaling in Telecommunication Networks: Books: John G. van Bosse   (Site not responding. Last check: 2007-10-31)
The rapid growth of telecommunication in recent years has necessitated the creation of increasingly powerful and complex signaling systems and procedures.
Signaling System No. 7 (SS7) is treated in detail through a separate examination of its constituent elements-including its message transfer, telephone user, and ISDN user parts.
Providing the reader with a solid grasp of the concepts of channel-associated and common-channel signaling, it is an important basic resource for students approaching the subject for the first time as well as engineers and technical managers seeking up-to-date information on the latest technology.

  Switching system reliability - Patent 4943999
When signaling information defining a call destination at the second switch unit is received, from a line or trunk at the first switch unit, a control arrangement of the first switch unit transmits second call signaling information defining the call destination to the second switching system via a first trunk.
Signaling bits are passed from the processor 66 to signal processor 65 with indications of their destination channel on time-multiplex line 63.
When the call signaling information received by one switching module defines a subscriber set or trunk connected to another switching module, a path through the time-multiplex switch 10 is located and established by the central control 30 to complete the connection.

 U.S. Patent: 6118797 - Use of sub-rate out-of-band channel to transport signaling bits over time division multiplexed ...
A common technique for transporting call control signals over a digital telecommunication network, such as, but not limited to a T-1 data rate network, is the use of `robbed`-bit signaling, in which least significant bits are `robbed` from selected DS0 communication channels and used instead for the transport of in-band signaling information (termed ABCD bits).
Although in-band, robbed bit signaling allows the service provider to use all of the available TDM channels for customer traffic, and has been found to be generally acceptable for the transport of quantized voice, it can constitute a significant impairment to the quality of transported data traffic.
A signaling channel message for a respective one of the (N=384) communication channels is formed of a plurality of successively transmitted signaling channel nibbles of the subdivided DS0 communication channel.

 Buy.com - Signaling in Telecommunication Networks : John G. Van Bosse : ISBN 9780471662884
The first nineteen chapters are dedicated to signaling in telecommunication networks, with "telecommunication" used in the traditional sense.
Subscriber [S.sub.p] sends a request-for-service signal to exchange A (by lifting the handset of a telephone) and then signals the digits of the telephone number of [S.sub.r] (with the dial or keyset of the telephone).
Since telecommunication terms originated rather independently in different countries, technical literature in English still uses different terms for the same concepts, depending on whether the authors are from the United States, from the United Kingdom, or from other English-speaking countries, or documents are translations from other languages.

 Network Security And Reliability
Signaling is the aspect of telecommunication that deals with controlling the network to create, maintain, and dismantle these paths.
Signaling today is accomplished over a separate data network that carries only the signals needed for signaling, namely, the data signals that control the operation of the network.
Telecommunication programs are usually very large, and their production requires the considerable time and effort of many programmers.

 Connectionless Signaling Network Layer in UMTS
The signaling applications involved in the signaling procedure can be abstracted from the change of BTS by the signaling network layer, allowing the signaling procedure to complete regardless of the handover between BTSs.
In a connection oriented approach, the signaling transactions with each node in the fixed network must be transferred through separate connections, each of which must be handled separately thus increasing the load when more than one connection is needed.
Signaling applications in UMTS are expected to communicate using upper layer end-to-end protocols which can include the capability to detect message loss.

Examples of such signals are pink noise or spectrum-shaped Gaussian noise, which nevertheless cannot be referred to as ``artificial voice'' for the purpose of this Recommendation.
The artificial voice is a signal that is mathematically defined and that reproduces the time and spectral characteristics of speech which signifcantly affect the performance of telecommunication systems.
This signal reflects parameters of human conversation such as the length of the talk spurt, pause, double talk, and mutual silence.

 Configuring T1 CAS for VoIP on Cisco AS5800 Access Server
The biggest disadvantage of CAS signaling is its use of user bandwidth to perform signaling functions.
CAS signaling is often referred to as robbed-bit-signaling because user bandwidth is being "robbed" by the network for other purposes.
To configure a channel group using CAS signaling, the ds0-group command is used to specify the channels/timeslots to be allocated for the CAS group and the CAS signaling type.
