Hardware Architecture for Universal Testing System: Cable Modem Test
A hardware architecture for a universal testing system used for performing tests on cable modem devices (DUT) is disclosed. According to certain embodiments, a CMTS test harness enables the DUT to respond to test phone calls from the MOCA interface and which test phone calls terminate at the DUT's phone port.
1 . A hardware architecture of a system for testing a plurality of cable modem devices under test, the hardware architecture of the system comprising:
a plurality of Faraday cages;
wherein:
each Faraday cage of at least a subset of the plurality of Faraday cages is in communication with a FXO port of a test server that is associated with the testing of the plurality of cable modem devices; and
each Faraday cage of the at least a subset of the plurality of Faraday cages is in communication with a phone port of a respective cable modem device under test of the plurality of cable modem devices under test.
2 . The hardware architecture of claim 1 , wherein each Faraday cage of the at least a subset of the plurality of Faraday cages is configured to enable the respective cable modem device under test to communicate with an Ethernet port of the test sever.
3 . The hardware architecture of claim 1 , further comprising at least one MOCA LAN harness configured to communicate with an Ethernet port of the respective cable modem device under test.
4 . The hardware architecture of claim 1 , further comprising at least one CMTS harness configured to communicate with a COAX port of the respective cable modem device under test.
5 . The hardware architecture of claim 3 , wherein the at least one MOCA LAN harness is configured to communicate with an Ethernet port of the test server.
6 . The hardware architecture of claim 4 , wherein the at least one CMTS harness is configured to communicate with an Ethernet port of an FXO server associated with the system.
7 . The hardware architecture of claim 4 , wherein the at least one CMTS harness is configured to provide IP addresses for a SIP server running on the cable modem device under test.
8 . The hardware architecture of claim 4 , wherein the at least one CMTS harness enables the respective cable modem device under test to respond to test phone calls from a MOCA LAN harness associated with the system.
