Cisco ASR 900 Series interface modules, including those enabled by the FLSASR900-1OC48 license, are designed to support a wide range of services, speeds, temperature ranges, and capabilities. They provide cost-effective delivery of converged circuit emulation, optical transport network, and business Ethernet services, overcoming limitations of legacy PDH, SONET, SDH networks by evolving to packet-based architectures.
Key Benefits
TDM/PDH/SONET/SDH Interface Modules
Migrating circuit-switched TDM/PDH/SONET/SDH to Ethernet/IP/MPLS is enabled by high-density modules supporting CEM standards, boundless scale over Flex LSP, central office modernization for DCS/ADM migration, smaller footprint with power savings.
The FLSASR900-1OC48 license activates one OC48/STM-16 port on compatible modules, supporting pay-as-you-grow with per-port activation. Modules support channelized OC48/STM-16 to clear channel T1/E1 (SAToP), DS3/E3 (SAToP), channelized T1/E1 (CESoP); clear channel CEP. Configurable SONET/SDH mode, line/internal clocking, high availability with ACR, 1+1 APS, MSP.
Supported Modules for OC48/STM-16
All modules support OIR for high uptime. Optics via pluggable SFP for OC48: ONS-SI-2G-I1 (IR 1310nm), L1/L2 (LR 1310/1550nm), S1 (SR 1310nm), industrial temp.
Ethernet Interface Modules Overview
ASR 900 Ethernet modules offer flexibility with time stamping for Y.1731 OAM, IEEE 1588-2008, SyncE; OIR support. Examples: 1-Port 100GE CPAK (A900-IMA1C), 2-Port 40GE QSFP (A900-IMA2F), 8-Port 10GE SFP+ (A900-IMA8Z), multi-mode Gigabit/10GE modules with extensive optics support (SFP/SFP+/QSFP/CPAK) for MMF/SMF/DWDM/CWDM/BiDi, reaches up to 80km+.
Multiservice Modules
Support legacy PPP/MLPPP/ATM/IMA/HDLC, PWE for TDM/ATM over IP/MPLS (CESoPSN/SAToP). Includes 6-Port E&M (A900-IMA6EM) for Smart-Grid/Teleprotection, 14-Port Serial RS-232 (A900-IMASER14A/S), 4-Port C37.94 for Utilities tele-protection.
Compatibility matrices ensure slot/IOS XE support across ASR 900 platforms (914/907/903/902) with RSP3C/RSP2A/RSP1A/B.
