Filed:

Jun 27, 2000

Appl. No.:

09/603715

Inventors:

Robert J. McGuire - Richardson TX

Assignee:

Alcatel, societe anonyme - Paris

International Classification:

H04Q 720

US Classification:

455522, 455 671, 455 63, 455453, 37911205

Abstract:

A method for transmitting data is provided. The method includes receiving a service request for a standby subscriber terminal, such as when a call is placed to or from the standby subscriber terminal. The number of telecommunications channels carried by a trunk group is then changed, such as by increasing or decreasing the number of encoded telecommunications channels carried by the trunk group. The standby subscriber terminal is then assigned to one of the telecommunications channels of the trunk group.

Appl. No.:

6/155982

Inventors:

Ned E. Abbott - McKinney TX

Robert J. McGuire - Richardson TX

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H09J 314

US Classification:

370 16

Abstract:

A muldem (100) has a monitor (101) for testing data path failures and standby data protective switching means (108, 109) providing an alternate data path in the event of a malfunction. The system accepts up to fifty-six standard low speed T1 LS lines (1. 544 Mb/s), up to fourteen standard intermediate speed T2 lines (6. 312 Mb/s), or any combination of T1 and T2 lines to generate to standard HS lines (44. 736 Mb/s). The T1 circuitry is replaceably interchangeable with the T2 circuitry.

International Classification:

H04B 160

US Classification:

455 8

Abstract:

A concept is illustrated for protecting active components in a multiline repeater station switching system to a state of "fail operability". This is accomplished by dividing the signal received on the single spare IF transmission line into IF and baseband signals and applying the divided set of signals to two spare switches. Thus, there is provision for using the spare line as either a repeat line staying at the IF frequency or as a drop line at baseband frequency. The same concept is used in the transmit portion wherein the output of two spare switches is combined to be transmitted over a single IF line. Thus, the single line can be used to input either a repeated IF signal or an insert baseband signal. A further concept of the invention is to make both the IF and baseband switching modules identical in electrical contact construction so that the multiline switch can be easily altered into any desired set of repeat and drop or insert combinations.

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H04J 314

US Classification:

370 16

Abstract:

A muldem (100) includes a transmit multiplexer section (103, 104) combining a variety of low speed and intermediate speed data inputs into a single high speed data output and a demultiplexer section providing low and intermediate speed outputs from a high speed input. A monitor tests data paths of the muldem for detection of malfunctions and initiates protective switching through a standby alternate data path around the low or intermediate speed circuits and, independently, around the high speed circuits.

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H04J 314

US Classification:

370 16

Abstract:

A muldem (100) has a monitor (101) for testing data path failures through the muldem (100) by comparing the latter's input and output. The muldem (100) has normally on-line data paths (103, 104) therethrough, and includes normally off-line standby data protective switching means (108, 109) providing alternate data paths. The monitor (101) tests on-line and off-line data paths before and after protective switching to the standby alternate data path, to guard against silent failures and to prevent switching to an inoperative path. In an auto-revert mode, a latched display continues to display an alarm, after the malfunction is corrected and the muldem has switched from standby to main.

International Classification:

H04J 314

US Classification:

370 13

Abstract:

A muldem (100) has a monitor (101) for testing data path failures through the muldem (100) by comparing the latter's input and output. The monitor (101) tests itself by injecting errors into one of the compared data streams for detection thereof if the monitor (101) and comparing means (806, FIG. 13a and b) is operating properly. Error injection is particularly accomplished by an error generator (922, FIG. 14) synchronously clocked with a data stream (904) through an exclusive OR gate (938). The error generator (922) includes a free running gated oscillator (924) and a pair of ganged flip-flops (926, 928) toggled by a clock signal (936) recovered from the data stream (904).

US Classification:

370 17

Abstract:

A muldem (100) has a monitor (101) for testing data path failures through the muldem (100) by comparing the latter's input and output. The monitor (101) includes comparing means (806, FIGS. 13a and b) with a data comparator (880, FIGS. 13b and 17) for bit error detection by comparision of a pair of data streams (A+B) processed through the monitor (101) from the input and output of the muldem (100). The data comparator (880) delays one of the data streams (A) by a fixed amount and variably delays the other data stream (B), and then slipshifts the data streams in time until they are in alignment to be compared. The data comparator (880) detects noncoincidences of bits in the two data streams and counts such errors over a given sampling interval, providing a bit error rate. If this rate is above a user selectable threshold, then a malfunction in the tested data path is probable, so the path is retested, using a longer sampling interval, to improve the statistical accuracy of the test. If the number of bit errors increases accordingly, then a malfunction is indicated and standby data path protective switching may be initiated.
