DASS2/DPNSS Card - EXS-DAS-1000
The DASS2/DPNSS card (for Digital Access Signaling System2/Digital Private Network Signaling System protocols) provides D channel packet processing and call control procedures. Both variants are similar to European ISDN Primary Rate Interface: They allow simplified Link Access Procedure (Layer 2) and call control of 30 B channels using a D channel on Timeslot 16 (30B + D) over a 64 Kbps interface.
The card has 4 Mb of battery-backed RAM and can be used in conjunction with line cards for rate conversion.
The DASS2/DPNSS card resides in the front slots of a CSP 2090, CSP 2110 or CSP 2040 chassis.
The part number, serial number, model number, and revision are located on the back of the board.
The DASS2/DPNSS card is designed to the following electrical, physical and environmental specifications.
