Systems, devices, and methods are disclosed for enabling the reconfiguration of services supported by a network of devices. Such reconfiguration can be realized dynamically and in real time without compromising the security of the overall system from external threats or internal malfunctions. These systems, devices and methods may provide a first functional stack supporting a previous version of a specific service and the provisioning of a second functional stack dynamically and in real-time that supports an updated version of the specific service. In addition, an administration function may be included in the embodiment such that the administration function manages and controls the functional stacks and network operations. Using these mechanisms, an existing service can be changed dynamically or a new service can be added dynamically in a secure manner without interruption of other existing services.

An apparatus for handling back-to-back maintenance messages in extended superframe t telephone circuits includes a FIFO, a byte counter, and a message length register. According toga method of the invention, when messages are placed in the. FIFO, the byte counter counts the message length and places the message length in the message length register. A host controller is required to read the message length register in the time interval following complete receipt of a first message before complete receipt of a second message, but is only required to read the contents of the FIFO before it overflows. According to a presently preferred embodiment of the apparatus, a second register is provided for indicating the current depth of the FIFO. The second register sends an interrupt to the host controller when the contents of the FIFO exceed a threshold.

A method and apparatus for reliably detecting both AIS and AIS-CI signals in the presence of a bit error ratio up to 1&times;10 includes an AIS detector having an AIS indication output, a CI detector having a CI indication output, and a two signal AND gate having its inputs coupled to the respective outputs of the detectors and having an output indicative of an AIS-CI detection. The AIS detector has an adjustable zero threshold and the CI detector has a threshold output coupled to the AIS detector for adjusting the zero threshold. According to the method of the invention, the AIS detector zero threshold is normally set at the normal threshold (1&times;10 ) but is reset to a higher threshold (e.g., 2&times;10 ) when the CI detector detects the presence of the CI code word. The AIS signal is detected in a normal way and the AIS-CI signal is detected only when the CI detector detects the presence of the CI code word AND the AIS detector detects the presence of the AIS signal using the higher zero threshold. According to a preferred embodiment, the zero threshold is raised if the CI detector detects two consecutive CI code words, but the CI indication output is indicated only of the CI detector detects eight CI code words in 40 ms. The zero threshold is returned to normal when the CI detector detects ten consecutive absences of the CI code word.

Circuit board insertion circuitry is used in conjunction with a staggered electrical connector. The insertion circuitry includes an isolated circuit which receives a high system voltage upon first stage contact between the card and a high voltage bus, and uses that high system voltage to tristate the output of a transceiver on the circuit board prior to second stage contact being made between the transceiver and the backplane data bus. Override circuitry for overriding the tristating effects of the isolating circuit are provided such that when the bias circuit which controls the transceiver output is properly powered, the bias circuit will control the transceiver output, and not the isolated circuit. Additional circuitry which isolates the circuit board so that a power fault on the board will not impact other boards on the backplane is also provided. The additional circuitry preferably includes a relative large resistor and a Schottky diode which are provided in parallel between a 5 V bus and the protection diodes of the transceiver.

A duplex digital transmitter system is disclosed which permits simultaneous digital signal exchange over a two-wire loop. Two sets are provided at the ends of the loop, each having a three-port lattice adapted to separate the transmitted and received digital signals. The digital signals are encoded using a biphase scheme so that they have a zero D.C. component. Therefore the loop is used simultaneously to transmit D.C. power from one set to the other.
