Software release

  • Junos OS Release 12.2 and later

For information on which MPCs support this MIC, see MIC/MPC Compatibility. For information on which MICs are supported on MX Series routers, see MICs Supported by MX Series Routers.

Description

  • Four OC3/STM1 ports

  • Rate-selectable using one of the following rates:

    • 4-port OC3/STM1

    • 1-port OC12/STM4

  • One channelized OC12/STM4 port (down to DS0)

  • SONET or SDH is configurable on a MIC level

  • OC3 channelization:

    • 4 OC3 channel

    • 336 DS1 channels

    • 2016 DS0 channels (combination of nxDS0)

  • SDH channelization:

    • 4 STM1 channel

    • 252 E1 channels

    • 2016 DS0 channels (combination of nxDS0)

  • Power requirement: 2.83 A @ 12 V (33.96 W)

  • Weight: 1.63 lb (0.74 kg)

  • Model number: MIC-3D-4COC3-1COC12-CE

Hardware features

  • Ports are numbered 0 through 3

Software features

  • Per-MIC SONET/SDH framing

  • Internal and loop clocking

  • Encapsulations:

    • Pseudo Wire Emulation Edge-to-Edge (PWE3) Architecture (RFC 3985)

    • Requirements for Pseudo-Wire Emulation Edge-to-Edge (PWE3) (RFC 3916)

    • Structure-Agnostic Time Division Multiplexing (TDM) over Packet (SAToP) (RFC 4553)

    • Structure-Aware Time Division Multiplexed (TDM) Circuit Emulation Service over Packet Switched Network (CESoPSN) (RFC 5086)

    • Pseudowire Emulation Edge-to-Edge (PWE3) Control Word for Use over an MPLS PSN (RFC 4385)

    • L2 Network Interconnections (protocol stitching):

    • Unified in-service software upgrade (unified ISSU)

Interfaces

Syntax: mediatype-fpc/pic/port where:

  • mediatype: coc3, coc12, cstm1, cstm4, or ds

  • fpc: Slot in the router where the MPC is installed

  • pic: 0 when installed in MIC slot 0 or 2 when installed in MIC slot 1

  • port: 0 through 3

For example, cstm4-1/2/0 is the channelized STM4 interface for port 0 on the MIC installed in MIC slot 1 on an MPC installed in slot 1.

Cables and connectors
Tip:

You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

The list of supported transceivers for the MX Series is located at https://pathfinder.juniper.net/hct/category/#catKey=100001&modelType;=All&pf;=MX+Series.

Note:

To extend the life of the laser, when a MIC is not being actively used with any valid links, take the MIC offline until you are ready to establish a link to another device. For information about taking a MIC offline, see the request chassis pic offline command in the Junos OS System Basics and Services Command Reference.

LEDs

OK/FAIL LED, one bicolor:

  • Green—MIC is functioning normally

  • Red—MIC has failed

LINK LED, one tricolor per port:

  • Off—Not enabled

  • Green—Online with no alarms or failures

  • Yellow—Online with alarms for remote failures

  • Red—Active with a local alarm; router has detected a failure

Alarms, errors, and events

Structure-agnostic alarms for T1 and E1 interface:

  • Alarm indication signal (AIS)

  • Loss of signal (LOS)

  • Line code violation (LCV)

  • Errored seconds (ES)

  • Line-errored seconds (LES)

  • Severely errored seconds (SES)

  • Unavailable errored seconds (UAS)

Structure aware alarms for T1 and E1 interface:

  • Severely errored frame (SEF)

  • Block error event (BEE)

  • Loss of frame (LOF)

  • Yellow alarm (remote alarm indication RAI)

  • Path code violation (PCV)

  • Severely errored frame seconds (SEFS)

  • Bursty errored seconds (BES)
