Atm Connections - Cisco 7000 Series Hardware Installation And Maintenance Manual

Connecting Interface Cables

ATM Connections

All AIP ATM interfaces are full-duplex. You must use the appropriate ATM interface cable to
connect the AIP with an external ATM network. The AIP provides an interface to ATM switching
fabrics for transmitting and receiving data up to 155 megabits per second (Mbps) bidirectionally; the
actual data rate is determined by the PLIM.
The AIP can support interfaces that connect to the following physical layers:
•
•
•
•
•
Connect the AIP interface cables as shown in Figure 3-7. For detailed descriptions of ATM cabling
requirements, refer to the section "Distance Limitations" in the chapter "Preparing for Installation"
and the section "ATM Connection Equipment" in the chapter "Preparing for Installation."

clip (CLIP-E3-EMI) on the receive port (RCVR); the DS3 PLIM connection does not require this
clip. Figure 3-8 shows the EMI filter clip assembly that is required for the E3 PLIM. Do not operate
the E3 PLIM without this assembly.
The E3 and DS3 PLIMs require cable CAB-ATM-DS3/E3. If you have an E3 PLIM, you must
follow Steps 1 through 3 to install the CAB-ATM-DS3/E3 cable and EMI filter assembly. If you do
not have an E3 PLIM, proceed to the appropriate section for your configuration.

To ensure compliance with EMI standards, the E3 PLIM connection requires an EMI filter
Attach the CAB-ATM-DS3/E3 cable to the transmit (XMTR) and receive (RCVR) ports on
the E3 PLIM. (See Figure 3-8a.)
One portion of the cable has a white insulator on both ends to ensure that the
receive-to-transmit and transmit-to-receive relationship is maintained between the E3
PLIM and your ATM switch. The portion of the cable with the white insulator should attach
between receive and transmit or transmit and receive ports of the E3 PLIM and your ATM
switch, respectively.
Hold the EMI filter clip as shown in Figure 3-8b and attach it to the receive cable as shown
in Figure 3-8c.
