Cabling the CE1 Frame Relay Port Adapter

Cabling the CE1 Frame Relay Port Adapter

This chapter describes supported cabling configurations for the channelized E1(CE1) Frame Relay 2.048-Mbps ATM port adapter, and 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 BNC or UTP port adapter interface with an external ATM network.

CE1 Frame Relay Port Adapter Supported Interfaces

The CE1 Frame Relay port adapter provides an interface to ATM switching fabrics for transmitting and receiving data at 2.048 Mbps bidirectionally. The actual data rate is determined by the physical layer interface module (PLIM). The CE1 Frame Relay port adapter can support interfaces that connect to the CE1 2.048-Mbps UTP cable with an RJ-48c connector.

Caution The CE1 Frame Relay ports must be connected to a network termination unit (NTU). NTU devices should comply with UL 1950, CSA 950, EN 60950, and IEC 950 standards.
Note For detailed descriptions of ATM cabling requirements, refer to the section "ATM Connection Equipment Requirements" in the chapter "Installing ATM Port Adapters."

CE1 Frame Relay Port Adapter Connectors

For the CE1 trunks, use an RJ-48c connector and UTP cable to connect the CE1 Frame Relay port adapter with the WAN or other switches. (See Figure 7-1.)

Note See the section "ATM Connection Equipment Requirements" in the chapter "Installing ATM Port Adapters" for a description of these connectors. (Figure 2-3 shows an RJ-48c connector.)

LED Description

CD (carrier detect)

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

RX (receive)

Off—No receive line activity
Flashing green—Cells being received: blinks every five seconds and pulse rate increases with data rate
Flashing yellow—Loopback
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.
