DDS Testing
For testing at a D4 channel bank, the DDS DS0A/B Module enables the FIREBERD 6000 to analyze DDS subrate circuits, with DS0A, DS0B, and clear channel compatibility for all data rates. The module provides complete loopback support, which allows a DDS circuit to be completely sectionalized in either direction using alternating and latching loopbacks. For testing DDS four-wire facilities to the customer premises, the DDS Local Loop Module emulates a DSU/CSU at all data rates, including 64 kb/s clear channel service. Unique stress and signal capabilities provide quick detection of marginal circuits and equipment. You can perform frame relay testing from any DDS access point¿both the DDS DS0A/B Module and the DDS Local Loop Module are completely compatible with the FIREBERD 6000 Frame Relay Option.
Features
