A switching architecture interconnecting remote switches to a central processor via standard links which may be set up through any number of intervening switching systems utilizing standard switching procedures. The standard links are ISDN links that may be set up dynamically via switching networks within the switching system or via the public switching network. The fact that an ISDN goes through a portion of the switching system or the public switching network is transparent to both the central processor and remote switch. Upon detecting that a primary central processor is no longer in control, each remote switch attempts to obtain an alternate path to the primary central processor. If a remote switch is unable to obtain an alternate path to the primary central processor, the remote switch switches to an alternate central processor on the assumption that the primary central processor has failed. Because the paths can be made on directly connected ISDN links, through the switching system, or through the public switching network to either the primary central processor or the alternate central processor, there is a high probability of a remote switch being able to obtain such a path.

A mobility management system and a traditional telecommunication switching system provide telecommunication terminal features by the mobility management system executing a software architecture that utilizes a unique terminal management application for each type of wireless terminal and a unique terminal emulator application for each type of telecommunication link that interconnects the mobility management system to the telecommunication switching system. There is an individually assigned telecommunication link for each wireless terminal. The terminal management applications and the terminal emulator applications communicate utilizing an internal message protocol. In response to a wireless terminal requesting actuation of a feature, a terminal management application converts that request into the required internal protocol messages and transmits the internal protocol messages to the terminal emulator application that controls the telecommunication link assigned to the wireless terminal. In response to the internal protocol messages, the terminal emulator application emulates the type of telecommunication terminal that normally would be connected to the assigned telecommunication link. The telecommunication switching system is responsive to the emulation to provided the requested feature as if telecommunication terminal was connected to the assigned link.

A switching architecture with identical switching nodes having a topology which allows for multiple paths between any two endpoint switching nodes without intervening switching nodes being involved in call control on those paths. This architecture is made feasible by a new type of link, the flexible rate interface (FRI) link. The FRI link has its own signaling channel distinct from the signaling channel of a standard link and is transparent to intervening switching nodes. Only endpoint switching nodes are aware of the existence of the FRI link with respect to call control. A standard protocol is utilized on the signaling channels of both the standard link and the FRI link. Advantageously, the standard link may be an ISDN link and the standard protocol may be the ISDN protocol. An FRI signaling channel of the FRI link may be established by using any of the following: a B channel of a standard ISDN link, standard ISN user information transport facilities, or a logical link of a D channel of a standard ISDN link. In combination with the FRI signaling channel, the FRI link may utilize B channels from a number of standard ISDN links for FRI B channels.

In a telecommunication switching system having a plurality of switch nodes with each of the switch nodes responsive to a failure of a communication link within a group of communication links to establish a flexible rate interface (FRI) link upon there being no spare channels within the group of communication links and to switch active calls from the channels of the failed communication link to the channels of the newly established FRI link. Advantageously, the group of communication links can be a non-facility access service (NFAS) group. Advantageously, this allows for additional B channels to be added to the NFAS group even though there are no remaining physical communication links between the two switch nodes being interconnected by the NFAS group. The establishment of the FRI link allows for the addition of B channels to the NFAS group with these B channels being routed through other switch nodes of the communication switching system. The FRI link becomes part of the NFAS group and control is provided for the B channels of the FRI link by the primary D channel of the NFAS group.

A communication switching system having a plurality of switch nodes with each of the switch nodes responsive to a failure of a communication link within a group of communication links to switch active calls from channels of the failed communication link to idle channels of other communication links within the group of communication links. If no idle channels are available within the group of communication links when the communication link fails, a predefined time is waited for a channel to become idle or a new communication link to be added to the group of communication links before the active channels are abandoned. Advantageously, the switching of the active calls to idle channels occurs quickly so that only a momentary interruption of the calls occurs. The group of communication links may advantageously be a non-facility access service (NFAS) group having a combination of ISDN BRI and PRI communication links. The calls can be either voice, video, or data calls.

An apparatus for establishing a flexible rate interface (FRI) link on a standard ISDN link. The FRI link has its own signaling channel that is distinct from the signaling channel of the standard ISDN link, and the signaling channel of the FRI link is transparent to intervening switching systems. There are no geographical restrictions on a FRI link. The signaling channel of a FRI link may be established by designating a B channel of a standard link, by using a logical link of a D channel of a standard ISDN link, or by using standard ISDN user information transport facilities to communicate the signaling channel. FRI transport channels are B channels of a standard ISDN link or subchannels of a B channel.

Routing calls using a new protocol message which is a redirect message in a telecommunication system having a number of switching nodes to avoid circular paths among the switching nodes and for rerouting calls in the event of failures or overload conditions. During the establishment of a call from an originating switching node to a destination switching node where the call path has already been setup from the originating switching node through an intermediate switching node, a switching node is responsive to a setup message from the intermediate switching node requesting extension of the call path through the switching node to determine if such an extension would create a circular path. If circular path would be created, the switching node redirects the call (by using the redirect message) back to the intermediate switching node and indicates in that message to which switching node the call path should be extended. In response to the redirect message, the intermediate switching node reroutes the call path.

A communication switching system having a plurality of switching nodes in which each switching node upon initialization completely establishes its own internal configuration. This establishment of internal configuration includes the number and type of switching modules and within each switching module: type of module control processor, type of internal switching network, printed board carriers, type and number of auxiliary circuits, and type and number of link interfaces. Each unit of a switching module reports relevant information to the module control processor; and in turn, the module control processor reports its own information and the information of the other units to a node processor (the main processor within a switching node). Further, each switching node and interfaces of the switching node automatically identifies the other switching nodes connected by communication links and switching paths to those switching nodes. Each interface upon being initialized automatically performs low level initialization operations over the connected link with the far end interface.
