ECTU
ATM Fabric Card for the CNX-5 T1 IMA Configuration
Technical information
| Network Interfaces | |
|---|---|
| ATM 4 port DS1 IMA | |
| Supports mix of DS1 UNI and 1-2 IMA groups | |
| Inverse multiplexing for ATM; IMA v1.0, v1.1 | |
| ATM Functionality | |
| UNI 3.0 and UNI 3.1-based ATM interfaces; will migrate to support TM 4.0 | |
| Multiple classes of service including: CBR, UBR, VBR-rt, VBR-nrt, UBRmdcr; and in future GFR | |
| 16 VCs with combinations of QoS per subscriber line | |
| Network interface overbooking and traffic shaping capability. Upstream policing capability | |
| VC shaping is provided toward the subscriber lines for multiple network-side VP services across the network link. Guaranteed QoS can be offered for delay-sensitive applications | |
| Will migrate to support ILMI auto-configuration of ATU-R, subscriber side SVC, UNI-based SPVC for reduced network operations, and packet services. Large buffers with full multi-grained congestion management, including EPD/PPD and multiple watermarks | |
| Compatible with multi-protocol encapsulation over ATM. Compatibility includes, but is not limited to, PPP over Ethernet (RFC2516), PPP over ATM (RFC2364) and Classical IP (RFC2225) | |
| Comprehensive ATM OAM (I.610 FM & PM) and ATM/DSL MIBs | |
| Interfaces to Ciena ECUs over legacy SLC-5 backplane without new cabling | |
| Robustness | |
| AC Power Fail Detect Feature | Enables turn-down of DSL service in the event of a power outage to preserve lifeline POTS battery life |
| Easy Recovery | Relevant DSL provisioning data is stored in non-volatile memory to allow for DSL service recovery from a power outage without EMS intervention |
| Legacy Test Functions | |
| Support for AUB22 CTU functionality, including remote test access, diagnostics and configuration of special service channel units | |
| Local interface to Craft Interface Unit (CIU) or SCAT II system | |
| Management Interfaces | |
| Craft interface via EIA-232 or 10BaseT Ethernet Supports IP over ATM in-band manage | |
