Product SummaryRAD's SPD-703-1 G.703 codirectional rate and interface converter transfers between the G.703 interface and other data communication interfaces. The SPD-703-1 codirectional converter converts the ITU G.703 64 kbps codirectional interface to V.35, V.36/V.11 or X.21/V.11, RS-530, V.24 or a built-in Ethernet bridge. Benefits• Enables straightforward communication between different products with different interfaces and data rates Further Product InformationG.703 interface conversionThe SPD-703-1 rate and interface converter transfers between the G.703 interface and other data communications interfaces. The SPD-703-1 codirectional converter converts the ITU G.703 64 kbps codirectional interface to V.35, V.36/V.11 or X.21/V.11, RS-530, V.24 or a built-in Ethernet bridge. Operating full duplex at a transmission rate of 64 kbps, the SPD-703-1 has a range of 800 meters (0.5 miles) from the G.703 equipment. It has a built-in BERT complying with the V.52 standard that provides fault isolation capability with the activation and monitoring performed via the front panel. V.54 diagnostic capabilities provide local analog, local digital and remote digital loopbacks. These may be activated from the front panel or via the interface control signal. The SPD-703-1 is available as a standalone unit that can be mounted in a 19" rack, or as a card for the ASM-MN-214 rack.
