A900-IMA8D-RF

ASR 900 8 port RJ48C T1/E1 Interface Module REMANUFACTURED

The A900-IMA8D-RF is a professionally remanufactured 8-port channelized T1/E1 interface module for the Cisco ASR 900 Series Aggregation Services Routers, designed for service provider mobile backhaul, TDM-over-MPLS, and circuit emulation deployments. Providing 8 independent T1/E1 ports with DSubminiature (DB-78 or RJ-48) connectors, this module enables aggregation of legacy TDM circuits into modern MPLS/IP transport networks. The IMA8D supports CESoP, SAToP, ATM IMA, and clock recovery via Synchronous Ethernet (SyncE) and PTP/1588v2.

This remanufactured interface module has been professionally inspected, tested, and restored to meet Cisco's quality standards for ASR 900 Series carrier-grade infrastructure. Each unit undergoes verification of all 8 T1/E1 ports, framing/line-code testing, and validation of clock recovery and timing distribution functions.

Key Features:
• 8 channelized T1/E1 ports configurable per-port for T1 (1.544 Mbps) or E1 (2.048 Mbps) operation
• Compatible with Cisco ASR 903 and ASR 907 chassis interface module slots
• Circuit Emulation Service over Packet (CESoP) and Structure-Agnostic TDM over Packet (SAToP)
• ATM Inverse Multiplexing (IMA) for legacy ATM transport over MPLS
• Synchronous Ethernet (SyncE) and IEEE 1588v2 PTP for precision timing distribution
• Hot-swappable design for non-disruptive insertion and removal in live chassis

This refurbished interface module is ideal for mobile network operators, wholesale carriers, and enterprises maintaining legacy T1/E1 circuits requiring migration to MPLS/IP transport while preserving timing and circuit integrity. Choosing remanufactured ASR 900 modules allows service providers to extend TDM-over-MPLS deployments cost-effectively while preserving full Cisco IOS XE software compatibility and Smart Licensing eligibility.
