摘要： A processor-controlled integrated telephone line measurement and conditioning apparatus installable at a remote site provides a multiplicity of measurement and conditioning functions that are selectively executable in response to commands issued from a supervisory command site. The dual measurement and conditioning capabilities of the architecture of the present invention impart both remote measurement unit (RMU) functionality and metallic access unit (MAU) functionality that may be individually accessed and controlled. The RMU operates primarily as a test head that performs mechanized loop testing (MLT) tasks, while the MAU is operative to impart prescribed electrical conditions to a specified line circuit. When controllably accessed to operate as an RMU, the present invention responds to instructions from a command site (loop maintenance operations systems) and performs single-line demand tests on a line provided by a pair gain system. To operate as an MAU, the system receives commands from a direct access test unit (DATU) and performs line conditioning functions on the test line provided by the pair gain system.

摘要： An autobaud detection mechanism, installed as part of the communication control software of a serial communication device's microcontroller, enables the device to automatically determine the baud rate employed by a remote digital data communications device. Starting with a default baud rate, corresponding to the highest available baud rate, the mechanism steps through successively lower baud rates in the course of a search for the baud rate at which the remote device is transmitting. When an incoming call is received, respective bits of the received data are examined for the presence of transmission errors. If a transmission error is detected, the baud rate is stepped to the next lowest baud rate. If no error is detected, the received data bits are compared with a reference character. If the two compared data bit patterns match, the controller locks the baud rate at that baud setting for the remainder of the call. When the call is terminated, the baud rate reverts to its default setting. If the bit pattern comparison does not indicate a match, the baud rate is stepped to the next lowest baud rate. When the autobaud detection routine has stepped to a new baud rate entry, it initiates a prescribed time-out as a safeguard against the receiver becoming `out-of-sync` with a transmitter. Once, the lowest baud rate has been reached, the routine steps to the default setting and starts again.
摘要翻译： 作为串行通信设备的微控制器的通信控制软件的一部分安装的自动波特率检测机构使得设备能够自动确定远程数字数据通信设备所采用的波特率。 从与最高可用波特率相对应的默认波特率开始，该机制在搜索远程设备正在发送的波特率的过程中逐步降低波特率。 当接收到来电时，检查接收到的数据的各个比特是否存在传输错误。 如果检测到传输错误，则波特率步进到下一个较低的波特率。 如果没有检测到错误，则将接收的数据位与参考字符进行比较。 如果两个比较的数据位模式匹配，则控制器将在该波特率设置下锁定波特率以用于剩余的呼叫。 当呼叫终止时，波特率恢复为默认设置。 如果位模式比较不表示匹配，则波特率步进到下一个最低波特率。 当自动波特率检测程序进入新的波特率条目时，它会启动一个规定的超时，作为防止接收机与发射机“不同步”的保护措施。 一旦达到最低的波特率，例程就会进入默认设置并重新开始。

摘要： A remote measurement unit for testing and conditioning one or more telephone lines includes multiple electronically erasable flash memory banks, which contain respective versions of the operating system employed by the test unit's micro-controller. An operating system modification routine employed by the host processor of a remote site allows the functionality of the remote test unit to be selectively modified by electronically installing an upgraded or downgraded version of the operating system, or by electronically selectively activating or deactivating one or more operational features of the currently active operating system. A reset routine ensures that the operating system modification mechanism will only boot up the `correct` one of the two quasi-redundant systems available to the RMU's microcontroller after a system modification has been performed. In addition, the temporary insertion of a no-op code field just prior to the beginning of the program prevents the RMU's processor from accidentally booting up a modified system until the system has been verified as operational.

摘要： A subscriber line circuit test and conditioning arrangement for use with a non-metallic (fiber optic) digital communication path-based digital communication network employs a single (basic rate ISDN) metallic channel unit (BMCU) installed at a site terminating the fiber optic communication path. A BMCU communicates with a central office test system using an auxiliary B-ISDN communication `test` channel portion (2B+D) channels of the time division multiplexed digital communication DS0 channels. Digital command and response signals are transported by the two ISDN bearer (B) channels and are coupled directly to tip and ring digital signal processors in the central office test system, without the need for intermediate digital-to-analog and analog-to-digital conversion by a metallic channel unit at a central office terminal, and that additionally performed by a central office terminal and central office switch. The data (D) channel is employed to conduct access, calibration and control communications with the metallic channel unit.

摘要： The rate of change of a metallic subscriber loop charging characteristic and the period of time elapsed subsequent to the coupling of testing circuitry of a remote test unit coupled to the line are measured. The operation of the testing circuitry within the remote test unit is initiated in response to the rate of change of line voltage reaching a preselected rate of change, prior to the elapsed period of time reaching a prescribed time value. If the measured period of time reaches a prescribed value prior to the monitored rate of change of line voltage reaching the preselected rate of change, the last sampled value of the line voltage is stored and reported to a mechanized loop test system supervisory site.

The communications unit has a contact-sensitive visual display, which converts touch inputs into control signals that are transmitted to the test system and through which information associated with the operation of the test system is presented to the user. The user's communication unit is operative, in response to a user's request for the establishment of a communication path between the communications unit and the test system, to attempt to place the communications unit in wireless communication with the telephone office. If the wireless path is unavailable, a message is displayed instructing the user to use a wireline path.
