5.6 5.6.1 STS-24c Restriction
switches (such as 1+1 automatic protection switching [APS], path protection, or bidirectional line switch
ring [BLSR]). Full provisioning support is possible through Cisco Transport Controller (CTC),
Transaction Language One (TL1), or Cisco Transport Manager (CTM).
The circuit sizes supported are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c.
5.6.1 STS-24c Restriction
Due to hardware constraints, the card imposes an additional restriction on the combinations of circuits
that can be dropped onto a G-Series card. These restrictions are transparently enforced by the
ONS 15454, and you do not need to keep track of restricted circuit combinations.
When a single STS-24c terminates on a card, the remaining circuits on that card can be another single
STS-24c or any combination of circuits of STS-12c size or less that add up to no more than 12 STSs (that
is a total of 36 STSs on the card).
If STS-24c circuits are not being dropped on the card, the full 48 STSs bandwidth can be used with no
restrictions (for example, using either a single STS-48c or 4 STS-12c circuits).
Note The STS-24c restriction only applies when a single STS-24c circuit is dropped; therefore, you can easily
minimize the impact of this restriction. Group the STS-24c circuits together on a card separate from
circuits of other sizes. The grouped circuits can be dropped on other G-Series cards on the ONS 15454.
5.6.2 G1000-4 Card-Level Indicators
The G1000-4 card faceplate has two card-level LED indicators, described in Table 5-11.
5.6.3 G1000-4 Port-Level Indicators
The G1000-4 card has one bicolor LED per port. Table 5-12 describes the status that each color
represents.
Table 5-11 G1000-4 Card-Level Indicators
Card-Level LEDs Description
FAIL LED (red) The red FAIL LED indicates that the card’s processor is not ready or that a
catastrophic software failure occurred on the G1000-4 card. As part of the
boot sequence, the FAIL LED is turned on, and it turns off if the software is
deemed operational.
The red FAIL LED blinks when the card is loading software.
ACT LED (green) A green ACT LED provides the operational status of the G1000-4. If the
ACT LED is green, it indicates that the G1000-4 card is active and the
software is operational.
