About the Cisco ASR 900 A900-IMA8D Cisco ASR 900 series module / router
The Cisco ASR 900 A900-IMA8D is managed through on-box Cisco IOS CLI with full support for centralised controller integration via NETCONF/YANG and SNMP — no separate licensing is required for the interface module itself, though management scalability depends on your ASR 900 chassis deployment model. This DS1/E1 channelized TDM interface module delivers eight ports of legacy circuit switching capacity within the Cisco ASR 900 Series platform, making it the ideal choice for network engineers bridging TDM and packet infrastructures in enterprise WAN environments.
The A900-IMA8D supports advanced routing protocols including OSPF, IS-IS, BGP, MPLS, and Segment Routing, enabling seamless integration into modern IP/MPLS networks. Circuit emulation over MPLS and IP is delivered via SAToP and CESoPSN pseudowire technologies, while precision timing is ensured through IEEE 1588v2 Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE). The module operates across 0°C to 45°C and is designed to meet NEBS Level 3 requirements per the ASR 900 platform. High availability features include hitless software upgrade (ISSU) capability, and management is unified across SNMP, NETCONF/YANG, and native Cisco IOS CLI interfaces.
Deployment Scenarios
- Legacy T1/E1 to MPLS service conversion in multi-site enterprise networks
- TDM circuit preservation and emulation for business-critical applications during network modernisation
- Carrier-class timing synchronisation across distributed branch locations using PTP and SyncE
- Integrated voice and data transport via pseudowire emulation over IP/MPLS backbone networks
- Redundant WAN edge connectivity combining channelized TDM with dynamic routing failover
Compatible with Cisco ASR 903 and Cisco ASR 907 platforms, the A900-IMA8D (manufacturer part number A900-IMA8D) is suitable for IT procurement teams and network architects standardising on carrier-grade edge routing. Contact Omnixon Global for a detailed specification review and to submit your RFQ.
