DS3/E3 MIC

Software release

• Junos OS Release 11.4 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

• Eight E3 or DS3 ports

• DS3/E3 MIC ports can be configured as one of the following:

  • 8 clear-channel DS3 ports

  • 8 channelized DS3 ports

  • 8 clear-channel E3 ports

  Note:

  You can upgrade the DS3/E3 MIC with the S-MIC-3D-8CHDS3 software license (purchased separately) to support DS3 channelization. Channelized DS3/E3 MIC is supported only on queuing MPCs. On the MX80 router, you also need an S-MX80-Q software license.

• DS3 or E3 is configurable on a per-port granularity

• DS3 channelization for the 8-port Channelized DS3/E3 MIC:

  • 8 DS3 channels

  • 224 DS1 channels

  • 2038 DS0 channels

• Power requirement: 4.0 A @ 9 V (36W)

• Weight: 4.4 lb (2 kg)

• Model numbers:

  • DS3/E3 MIC: MIC-3D-8DS3-E3

  • Channelized DS3/E3 MIC: MIC-3D-8CHDS3-E3-B

Hardware features

• Ports are numbered 0 through 7, Tx0 through Tx7 and Rx0 through Rx7

Software features

• Maximum transmission units (MTUs) of up to 9192 bytes

• Framing: M13, C-bit parity, framed clear channel

• Subrate and scrambling:

  Note:

  Only DS3 interfaces support subrate and scrambling.

  • Digital Link/Quick Eagle

  • Kentrox

  • Larscom

  • ADTRAN

  • Verilink

• Internal and look clocking

• DS3 far-end alarm and control (FEAC) channel

• Full bit error rate test (BERT) for DS0, DS1, and DS3

• Encapsulations:

  • MPLS fast reroute

  • MPLS CCC (circuit cross-connection)

  • MPLS TCC (translational cross-connection)

  • Cisco High-Level Data Link Control (cHDLC)

  • Cisco HDLC CCC

  • Cisco HDLC TCC

  • Point-to-Point Protocol (PPP)

  • PPP for CCC

  • PPP for TCC

  • Flexible Frame Relay

  • Frame Relay

  • Frame Relay for CCC

  • Frame Relay for TCC

  • PPP over Frame Relay

  Note:

  Ethernet over Frame Relay is not supported.

• Encapsulations available only for Channelized DS3/E3 MIC (Junos OS Release 12.1 and later):

  • Multilink Point-to-Point Protocol (MLPPP)

  • Multiclass MLPPP

  • Multilink Frame Relay (MLFR) end-to-end (FRF.15)

  • Multilink Frame Relay (MLFR) UNI NNI (FRF.16, also referred to as MFR)

  • Compressed Real-Time Transport Protocol (CRTP)

  Note:

  When you configure multilink services on a MIC in an MX Series router, ensure that a Multiservices DPC is present in the same router.

Cables and connectors

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.

LEDs

OK/FAIL LED, one bicolor:

• Green—MIC is functioning normally
