Cabling the 622-Mbps Port Adapter

Cabling the 622-Mbps Port Adapter

This chapter describes supported cabling configurations for the 622-Mbps port adapter, which provides single-mode, multimode, and single-mode long reach connections. This chapter is organized into the following sections:

For detailed, up-to-date configuration instructions, see the following publications:

  • Catalyst 8540 MSR Software Configuration Guide

  • LightStream 1010 ATM Switch and Catalyst 8510 MSR Software Configuration Guide

  • Catalyst 5000 Series Software Configuration Guide

For command-line interface (CLI) command descriptions, see the following publications:

  • Catalyst 8540 MSR Command Reference

  • LightStream 1010 ATM Switch and Catalyst 8510 MSR Command Reference

  • Catalyst 5000 Series Command Reference

Note All ATM interfaces are full duplex. You must use the appropriate ATM interface cable to connect the ATM single-mode or multimode interface with an external ATM network.

622-Mbps Port Adapter Supported Interfaces

The 622-Mbps port adapter can support interfaces that connect to the following physical layers:

  • SONET 622-Mbps multimode fiber-optic—STS-12C/STM 4

  • SONET 622-Mbps single-mode fiber-optic—STS-12C/STM 4

Note For descriptions of ATM cabling requirements, refer to the section "ATM Connection Equipment Requirements" in the chapter "Installing ATM Port Adapters."

622-Mbps Port Adapter Connectors

To connect the 622-Mbps multimode or single-mode port adapters to the external ATM switch, use an SC-type connector for multimode, single-mode, or single-mode long reach fiber-optic traffic. (See Figure 4-1.)

Note For a description of an SC-type connector, see the section "ATM Connection Equipment Requirements" in the chapter "Installing ATM Port Adapters."
(See Figure 2-2.)

Caution If you are attaching a short cable to the OC12, 622-Mbps long reach port adapter, you must add 10 decibels per milliwatt (dBm) of attenuation in the line or the transmitter can overdrive the receiver and introduce data errors.

622-Mbps Port Adapter LEDs

The LEDs provide status information for the individual 622-Mbps single-mode and multimode fiber-optic connections. The LEDs are described in Table 4-1 and shown in Figure 4-1.

LED Description

CD (carrier detect)

Off—Carrier detect signal not received
Green—Carrier detect signal received

RX (receive)

Off—Administration down
Flashing green—Cells being received: pulse rate increases with data rate
Red—Alarm (LOF1, LCD2, AIS3)

TX (transmit)

Off—No transmit line activity
Flashing green—Cells being transmitted: pulse rate increases with data rate
Flashing yellow—Loopback
Steady yellow—Alarm FERF4
1LOF = loss of frame.
2LCD = loss of cell delineation.
3AIS = alarm indication signal.
4FERF = far-end receive failure.
