摘要： A modular multi-service telecommunication access device includes a controller card and card slots for six peripheral cards and a power supply. Any of several types of peripheral cards can be inserted into the six card slots. A card present/protocol scheme allows an inserted card to recognize its address and communicate same as well as its communication protocol to the controller card via a PCM highway. The controller card sends both signaling information and management information to the peripheral cards via another PCM highway. A unique communication protocol allows for both real time signaling information and non-real time management information to be sent on the same channel. A microprocessor on the controller card includes an algorithm for managing messages to the various peripheral cards in the various card slots. A unique tributary addressing scheme allows for a simplified address used by external users to be converted to a more detailed internal address. A battery sense circuit includes a variable resistive element used in conjunction with additional circuitry to sense conditions relevant to the battery. A unique ringer circuit includes a boost converter for producing a sufficiently high voltage for the circuit. A faceplate provided on each of the circuit cards has resilient fingers thereon for selective mating with the chassis of telecommunication device.

摘要： A multiplexer for multiplexing and demultiplexing signals between a low-speed network and a higher speed network includes 7 quad DSX-1 cards and 1 spare card. The spare card is connected to the DSX-1 cards to allow the spare card to automatically be switched in for one of the DSX-1 cards or to allow interface electronics on the spare card to replace selected ones of interface electronics on different DSX-1 cards simultaneously. A pair of controller cards, a primary card and a secondary card, perform M1-3 multiplexing and demultiplexing and the DS-3 framing and transceiving. The controller cards can be selected or deselected in a short time period alarms are not set off and so that the transition is hitless by electronically enabling and disabling the transceiver. The multiplexer is connectable to 2 different T-3 links to provide network redundancy. An array of relays connected either controller card to either of the T-3 links. The controller cards are externally connectable to a computer network for external control thereof. The multiplexer is housed within a reduced volume which occupies a single rack unit on a standard vertical rack used for telecommunications equipment due to a dual backplane architecture in which an external backplane serves as the external connector plane while a separate internal backplane serves as the connection to the DSX-1 cards and controller cards.

摘要： A multiplexer device for multiplexing and demultiplexing signals between a low-speed network including 28 DSX-1 signals and a relatively higher speed network including a DS-3 signal. The multiplexer device includes 7 quad DSX-1 cards and 1 spare card. The spare card is connected to the other 7 DSX-1 cards in a fashion that allows the spare card to automatically be switched in for one of the DSX-1 cards or to allow interface electronics on the spare card to replace selected ones of the interface electronics on various different DSX-1 cards simultaneously. A pair of controller cards, a primary card and a secondary card, perform the M1-3 multiplexing and demultiplexing and the DS-3 framing and transceiving. The controller cards can be selected or deselected by distributed logic in a sufficiently short time period so that alarms are not set off and so that the transition is hitless. This is accomplished by electronically enabling and disabling the transceiver. The multiplexer device is connectable to 2 different T-3 links to provide network redundancy. An array of relays provides for the connection of either controller card to either of the T-3 links. The controller cards are externally connectable to a computer network such as an Ethernet for external control thereof through SNMP or Telnet sessions. The multiplexer device is housed within a significantly reduced volume which occupies only a single rack unit on a standard 19" or 23" wide vertical rack used for telecommunications equipment. The significantly reduced volume is partially due to a dual backplane architecture in which an external backplane serves as the external connector plane while a separate internal backplane serves as the connection to the various DSX-1 cards and controller cards.
