The ONS 15454 DS3-12E card provides 12 Telcordia-compliant ports per card. Each port operates at 44.736 Mbps over a single 75 ohm 728A or equivalent coaxial span. The DS3-12E card provides enhanced performance monitoring functions. The DS3-12E can detect several different errored logic bits within a DS-3 frame.

Each DS3-12E port features DSX-level outputs supporting distances up to 450 feet. With the proper backplane EIA, the card supports BNC or SMB connectors.

The Cisco ONS 15454 SONET 48-Port DS-3/EC-1 Interface Card provides a cost-effective, high-density DS-3/EC-1 interface solution for hand-offs and aggregation of large numbers of DS-3 and EC-1 circuits between networks. The card's high-density design frees up shelf-assembly slots for additional service-interface types.

15454E-DS3IN-12 12-port DS-3 Interface Card provides twelve ITU-T G.703, GR-499, ITU-T G.704 compliant DS-3 ports per card. Each port operates at 44.736 MBits/s (Mbps) over a 75 ohms coaxial cable. The DS3iN-12 can detect several different errored logic bits within a DS-3 frame. It is designed to terminate DS-3 signals originating on a Cisco ONS 15454 SDH platform; operates as either a working or protection card, industrial temperature rated, SONET system.
