Apparatus and method for testing an xDSL transceiver unit-central office
First Claim
1. An apparatus for testing an xDSL transceiver unit-central office, comprising:
- a multiplexer for connecting all ports of a modem installed in a transceiver unit-central office, and for setting a link with a subscriber transceiver unit by selecting one of the ports of the modem according to a link setup control signal;
a line simulator for supplying line types designated according to a test environment setup control signal and line states in accordance with a set noise; and
a tester for storing a set test environment from a user, for transmitting the link setup control signal having a link number for test to the multiplexer, for transmitting the test environment setup control signal to the line simulator after designating line types and setting noise, for activating a port to be tested by transmitting the link setup control signal having the link number for test and a designated communication parameter value of the link to the transceiver unit-central office, and for receiving and storing link states from the transceiver unit-central office.

Abstract
A tester and related method test an xDSL transceiver unit-central office so as to measure performance of a transceiver unit by automatically converting many output ports by connecting a multiplexer to the xDSL transceiver unit. A transceiver unit-central office tester comprises: a multiplexer for connecting all ports of a modem installed in a transceiver unit-central office, and for setting a link with a subscriber transceiver unit by selecting one of the ports of the modem according to a link setup control signal; a line simulator for supplying types of lines designated according to a test environment setup control signal and line states in accordance with a set noise; and a tester for storing a set test environment from a user according to the set test environment, for transmitting the link setup control signal having a link number for test to the multiplexer, for transmitting a test environment setup control signal to the line simulator after designating the line types and setting the noise, for activating a port to be tested by transmitting the link setup control signal having the link number for test and a designated communication parameter value of the link to the transceiver unit-central office, and for receiving and storing a link state from the transceiver unit-central office.

8. A method of testing an xDSL transceiver unit-central office, comprising the steps of:
-
(a) initializing a line simulator, a multiplexer, and a transceiver unit-central office;
(b) transmitting a link setup control signal designating communication parameter values of a link as predetermined values to the transceiver unit-central office, and making the transceiver unit-central office set the link according to the designated communication parameter values;
(c) transmitting a test environment setup command including line type information and noise environment information to the line simulator, and making the line simulator set line types and a noise environment;
(d) selecting a port among a plurality of modem ports of the transceiver unit-central office, and making the multiplexer set a link by controlling the multiplexer; and
(e) activating a port to be tested by transmitting a port activation command to the transceiver unit-central office, and storing link states transmitted from the transceiver unit-central office. - View Dependent Claims (9, 10)
