Channelized OC3/STM1 Circuit Emulation PIC with SFP (M7I Router)

Image g002615.gif

Software release

  • JUNOS 9.3 and later

Description

  • Four OC3/STM1 ports
  • Power requirement: 0.52 A @ 48 V (25 W)
  • Channelization: DS1

    Channelization down to E1/T1

    Each port can be channelized as 84 T1 ports for a total of 336 T1 pseudowires or 63 E1 ports for a total of 252 pseudowires.

  • Full bit error rate test (BERT)
  • Encapsulations: Structure-agnostic time-division multiplexing (TDM) over packet (SAToP) (RFC 4553)

Cables and connectors

  • Duplex SC/PC connector (Rx and Tx)
  • Optical interface support—See Table 5

LEDs

OK LED, one tricolor:

  • Off—PIC is offline and it is safe to remove it from the router.
  • Green—PIC is operating normally.
  • Yellow—PIC is initializing.
  • Red—PIC has an error or failure.

APP LED, one bicolor:

  • Off—Monitoring application is not running.
  • Green—Monitoring application is running under acceptable load.

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 interface:

  • Alarm indication signal (AIS-L, AIS-P)

  • Unavailable errored seconds (UAS)
  • Bipolar violation (BPV)
  • Controlled slip (CS)
  • Line code violation (LCV)

Structure agnostic alarms for E1 interface:
