• 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

• RJ-48 connector

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.
