The CR53-P10-4xATM/STM1-SFP is a 4-port OC-3c/STM-1c ATM flexible interface card with SFP slots, delivering up to 155.52 Mbps per port for high-speed backbone and edge aggregation.
This card supports any industry-standard OC-3c/STM-1c SFP transceiver that complies with Telcordia GR-253, including modules from Cisco, Finisar, and other major vendors.
Each port auto-negotiates OC-3c/STM-1c line rates at 155.52 Mbps, supporting both ATM and STM-1c framing modes.
The card provides four independent SFP-based interfaces, each configurable as OC-3c/STM-1c ATM ports for flexible network deployment.
Built-in support includes ATM AAL5/AAL2, OAM F4/F5, VC/VP multiplexing, and STM-1c SDH framing for seamless integration with legacy and modern networks.
Ideal use cases include ATM backbone aggregation, SDH trunking, TDM migration, Metro Ethernet backhaul, and multi-service edge deployments.
Designed for CRTIME and compatible chassis suites that accept PIC-style cards; verify slot compatibility in your router or switch documentation.
Power down the chassis, insert the card into an available PIC slot, secure with captive screws, power up, and verify detection via the system CLI.
Under full load, the card consumes approximately 5 W, well within typical chassis power budgets.
Supported protocols include native ATM, PPP over ATM, SDH/SONET, ILMI, OAM, and multi-protocol encapsulation over VC-maps.
Use the device CLI or web GUI to assign logical interfaces, select OC-3c/STM-1c mode, set line protocol, and apply SFP type parameters.
Yes, when installed in a chassis that supports PIC hot-swapping, the card can be inserted or removed without powering down the system.
Operating temperature ranges from 0 °C to 45 °C, with relative humidity from 5 % to 85 % non-condensing.
Management options include SNMPv2/v3, CLI, web UI, and RMON counters for real-time performance and fault monitoring.
Yes, it provides per-VC QoS, traffic shaping, policing, and priority queuing to ensure deterministic service levels.
The card includes a one-year limited hardware warranty; extended maintenance and support contracts are available for purchase.
