Example ATM-Layer Loopbacks
The following sections provide an overview on running some segment loopbacks. For an:
• Avidia channel card to loopback at a modem, see page 62 .
• Avidia line card to loopback at an ATM switch, see page 63 (this can also be an end-to-end
loopback when a VPC or VCC terminates at the switch).
• Avidia line card to loopback at an ATM node beyond the ATM switch, see page 63 (this
can also be an end-to-end loopback when a VPC or VCC terminates at the ATM node).
• ATM switch to loopback at a modem, see page 64 (this can also be an end-to-end
loopback).
• ATM switch to loopback at an Avidia line card, see page 65 .
• ATM node beyond the ATM switch to loopback at a modem, see page 65 (this can also be
an end-to-end loopback).
• ATM node beyond the ATM switch to loopback at an Avidia line card, see page 66 .
The following sections provide an overview on running some end-to-end loopbacks. For an:

the switch), see
page 63 .
• Avidia line card to loopback at an ATM node beyond the ATM switch, see page 63 (this
can also be a segment test).
• Avidia line card to loopback at a modem, see page 67 .
• ATM switch to loopback at a modem, see page 64 .
• ATM node beyond the ATM switch to loopback at a modem, see page 65 .
You can also run loopbacks to subtended Avidia systems. For a subtended Avidia segment
loopback, see
page 68 . To configure and run any OAM loopbacks, go to “OAM Alarms and
Loopbacks” on page 57 .
