Card Descriptions
Table 91 Equipment LEDs on 4-Port ATM OC-3c/STM-1c IR Card
Label Activity Color Description
On Red A failure exists on the card.
(1)
FAIL
Off None No failure exists on the card.
On Green This card is in service.ACTIVE
Off None This card is either on standby (the STDBY LED is on) or has failed (the FAIL
LED is on).
On Yellow At least one of the ports on this card has been configured as a protection port.
(2)
STDBY
Off None None of the ports on this card has been configured as a protection port.
(1) A failure can be total, partial, or forced. Failure on any part of the card, including failure of any of its ports, results in
the FAIL LED being on.
(2) Protection for cards and ports depends on the release of the SmartEdge OS.
Table 92 Facility LEDs on 4-Port ATM OC-3c/STM-1c IR Card
Label Activity Color Description
On Green Signal is present and within specifications.
Blinking Green Signal is present and within specifications; receiving or transmitting packets
(not idle cells).
LINK
Off None Port is not configured, no signal is present, or signal is not within specifications.
On Yellow Local port is in an alarm state, such as a loss of frame (LOF).LOC
Off None Local port is in a normal state.
On Yellow Remote port cannot obtain synchronization, or has a defect or failure, such
as an alarm indication signal (AIS).
REM
Off None Remote port is in a normal state.
6.4 1-Port Enhanced ATM OC-12c/STM-4c Card
The 1-port Enhanced ATM OC-12c/STM-4c Intermediate Reach (IR) card
supports one SONET or SDH SMF port, which operates at 622 Mbps, and can
be used either as an optical line or optical trunk interface. In addition, this card
can be used to support subscriber circuits.
Note: The 1-port Enhanced ATM OC-12c/STM-4c IR card is also referred to
as a second-generation ATM OC-12c/STM-4c card.
The card uses two SAR devices. The ingress SAR performs the reassembly
function on the incoming ATM cell stream from the physical device. The egress
SAR performs the segmentation function to create the corresponding outgoing
ATM cell stream.
The hardware provides header error control (HEC) framing for the port. The
transmit clock can be derived either from the active controller card or from
the onboard local oscillator.
This card supports up to 16,000 ATM permanent virtual circuits (PVCs).
