Abstract

A master test system may comprise cable modem termination systems, resource servers, provisioning/Session Initiation Protocol (SIP) servers, call management system (CMS) servers, Data over Cable Service Interface Specification/Wide Area Network (DOCSIS/WAN) servers, test controller servers, etc. Servers on the master test system may facilitate tests of devices under test (DUTs) coupled to the master test system. Servers on the master test system and/or slave test systems may facilitate tests of DUTs coupled to slave test systems that are coupled to the master test system. The slave test system(s) may comprise resource servers and test controller servers. In various implementations, the servers on the slave test system(s) may facilitate tests of DUTs coupled to the slave test system(s).

identifying first resource test protocols, the first resource test protocols providing a basis to test compliance of one or more resource parameters of the first plurality of devices under test;

identifying second resource test protocols, the second resource test protocols providing a basis to test compliance of one or more resource parameters of the second plurality of devices under test;

configuring a group of shared probes at the master test system to implement the shared test protocols on the first plurality of devices under test and the second plurality of devices under test;

configuring a first group of resource probes at the master test system to implement the first resource test protocols on the first plurality of devices under test; and

providing to the first slave test system instructions to configure a second group of resource probes at the first slave test system to implement the second resource test protocols on the second plurality of devices under test.

2. The method of claim 1, wherein the first plurality of devices under test are housed in a first plurality of test slots configured to protect the first plurality of test devices under test from electromagnetic interference.
