  • Encapsulations:

    • High-Level Data Link Control (HDLC)

    • Frame Relay

    • Circuit cross-connect (CCC)

    • Translational cross-connect (TCC)

Cables and connectors

  • Duplex LC/PC Connector (Rx and Tx)

  • SONET/SDH OC48/STM16 fiber-optic SFP transceivers:

    • Short reach (SR-1) (model number: SFP-1OC48-SR)

    • Intermediate reach (IR-1) (model number: SFP-1OC48-IR)

    • Long reach (LR-1) (model number: SFP-1OC48-LR)

    Optical interface specifications—see SONET/SDH OC48/STM16 Optical Interface Specifications

Note: To extend the life of the laser, when a PIC is not being actively used with any valid links, take the PIC offline until you are ready to establish a link to another device. For information about taking a PIC offline, see the request chassis pic offline command in the CLI Explorer.


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

    • Bit interleaved parity (BIP) error B1

    • Bit interleaved parity (BIP) error B2

    • Bit interleaved parity (BIP) error B3

    • Loss of frame (LOF)
