In a nationwide carrier backbone, operators leverage the SPA-1XCHSTM1/OC3-Cisco ASR 9000 Adapter SPA-1XCHSTM1/OC3 1-port Channelized STM-1/OC-3c to DS0 Shared Port Adapter to channelize OC-3c circuits into 63 DS0 channels for legacy TDM voice and leased-line services. This deployment maximizes link utilization, reduces provisioning time by 50%, and ensures carrier-grade availability with full SLA compliance.
Global banks integrate the SPA-1XCHSTM1/OC3 adapter on Cisco ASR 9000 routers to partition STM-1 links into dedicated DS0 circuits for secure PBX trunking across international branches. This solution delivers low-latency voice connectivity, streamlines trunk provisioning by 40%, and enforces PCI DSS and ISO 27001 compliance through isolated TDM channels.
Municipal public safety agencies deploy the SPA-1XCHSTM1/OC3 module on Cisco ASR 9000 platforms to convert OC-3c feeds into granular DS0 channels for mission-critical voice and data circuits. The adapter provides sub-50 ms failover, channel isolation for multi-agency interoperability, and ensures uninterrupted 24/7 communication during emergencies.

The SPA-1XCHSTM1/OC3 is a Cisco ASR 9000 adapter that converts a single STM-1/OC-3c port into up to 63 DS0 time-division multiplexed channels for voice, data, and TDM services.
The SPA-1XCHSTM1/OC3 is supported on Cisco ASR 9000 Series routers equipped with SPA-aware slots, including the ASR 9904, ASR 9906, ASR 9912, and ASR 9922 chassis.
The adapter offers up to 63 individually channelized DS0 timeslots over a single STM-1/OC-3c interface, enabling granular service delivery.
It supports ITU-T G.703 framing and accepts both G.823 compliant clocking and adaptive clock recovery for STM-1/OC-3c transport.
The module delivers up to 155.52 Mbps of aggregate bandwidth on the STM-1/OC-3c interface, with DS0 sub-rate allocation per configured channel.
Key features include channelized DS0 mapping, precision clocking support, hot-swappable installation, comprehensive SNMP monitoring, and End-to-End performance statistics.
Power down the router, insert the SPA into a compatible SPA slot until it clicks, resecure the slot cover, power on the system, and verify module detection in IOS-XR.
Use an ST-multimode fiber connector for OC-3c applications or a 75 Ω coaxial cable for 2048 kbps DS1 framing with an optional BNC transition.
It’s ideal for TDM service aggregation, legacy voice migration to packet networks, leased line replacement, and interworking between TDM and Ethernet/MPLS services.
It consumes under 15 W, operates between 0 °C and 45 °C, requires a relative humidity of 5–85% non-condensing, and meets NEBS Level 3 requirements.
It supports Channelized E1/T1, Clear Channel, HDLC, PPP, Frame Relay, and voice codecs when combined with voice gateway functionality on Cisco IOS-XR.
Cisco recommends IOS-XR Release 5.3.3 or later for full feature support, performance enhancements, and ongoing security fixes.
Use Cisco IOS-XR CLI for interface and DS0 mapping commands, and monitor performance via SNMP MIBs (CISCO-ENTITY-SENSOR-MIB, IF-MIB) or Embedded Event Manager.
Verify physical layer status with “show controllers stm1/oc3”, confirm clocking configuration, check cable continuity, and review syslog for CRC and LOS alarms.
Order by SKU SPA-1XCHSTM1/OC3. Each unit ships in an anti-static bag with mounting screws, product documentation, and a Cisco warranty registration card.
The adapter includes a limited lifetime hardware warranty, and optional Cisco SMARTnet support provides 24×7 access to Cisco TAC, software updates, and advance hardware replacement.
