Description

  • Sixteen E1 or T1 ports

  • Per-MIC E1/T1 framing

  • DS1 channelization per MIC:

    • 1 DS1 channel

    • 24 DS0 channels

  • E1 channelization per PIC:

    • 1 E1 channel

    • 32 DS0 channels

  • Internal and loop clocking

  • Power requirement: 2.21 A @ 12 V (26.55 W)

  • Weight: 1.57 lb (0.71 kg)

  • Model number: ACX-MIC-16CHE1-T1-CE

Hardware features

  • Ports are numbered:

    • Top row: 8 and 15 from left to right

    • Bottom row: 0 and 7 from left to right

Software features

  • Full bit error rate test (BERT)

  • DS1 and E1 interfaces are selectable on a per-port granularity

  • Per-port framing is not supported

  • You can configure the following framing modes using the CLI:

    • T1—SF, ESF, D4/superframe, ESF (extended superframe)

    • E1—G704, G704–no-crc4, unframed

  • Local, remote, and per-port loopback diagnostics

  • Encapsulations:

    • Pseudowire Emulation Edge to Edge (PWE3) Architecture (RFC 3985)

    • Requirements for Pseudowire 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)

Cables and connectors

  • RJ-48 connector

LEDs

OK/FAIL LED, one bicolor:

  • Green—MIC is functioning normally.

  • Yellow—MIC has failed.

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.
