Cisco ASR5K-SPS3-BNC-K9 ASR 5000 BNC BITS SPIO with Stratum 3

BNC timing I/O with the Stratum 3 module

ASR5K-SPS3-BNC-K9 is listed by Cisco as Switch Processor I/O with BNC BITS and Stratum 3. The installation guide classifies it as a half-height card and distinguishes it from ASR5K-SPIO-BNC-K9, whose exact description does not include the Stratum 3 module.

Timing-specific acceptance

Verify the full PID, BNC timing cabling, intended synchronization source and slot compatibility. Do not substitute the 3-pin BITS variant or the non-Stratum-3 BNC SPIO merely because the connectors appear related.

Obsolete platform control

Cisco's ASR 5000 notice records January 30, 2016 as end of sale and January 31, 2021 as the last support date. Any retained unit needs documented spares, configuration custody and a migration plan; the notice directs migration evaluation toward later VPC platforms.
