JUNIPER MIC-4COC3-1COC12-CE-H Networks MX-series (MX104) Modular Interface Card family Router Line Card

The Juniper MIC-4COC3-1COC12-CE-H is a temperature-hardened, multi-rate channelized circuit-emulation Modular Interface Card (MIC) for Juniper Networks MX-series routers, specifically the MX104 platform. It provides either 4 ports of channelized OC3/STM1 or 1 port of channelized OC12/STM4 (configuring port 0 for OC12 disables ports 1-3), with channelization down to DS0 level, and requires a pluggable SFP optics module to operate. Circuit emulation MICs of this kind let an MX-series IP/MPLS router carry legacy TDM traffic (down to individual DS0 channels) across a packet-switched network, a common requirement when migrating SONET/SDH-era services onto modern router infrastructure. The “-H” designation marks this as the temperature-hardened variant, suited to environmentally uncontrolled cabinet or outside-plant deployments; this card is marked end-of-life by Juniper. Tech-Star (UK-based, shipped worldwide) supplies tested Juniper router line cards; contact our engineers to confirm compatibility with your specific MX104 configuration before ordering.
