3.6.4 DS3-12 and DS3N-12 Port-Level Indicators
You can find the status of the 12 DS3-12 and 12 DS3N-12 card ports by using the LCD screen on the
ONS 15454 fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen
displays the number and severity of alarms for a given port or slot.
3.7 DS3/EC1-48 Card
Note
For hardware specifications, see the
“A.5.4 DS3/EC1-48 Card Specifications” section on page A-20
.
The ONS 15454 DS3/EC1-48 card provides 48 Telcordia-compliant, GR-499 DS-3 ports per card. Each
port operates at 44.736 Mbps over a single 75-ohm 728A or equivalent coaxial span. The DS3/EC1-48
card operates as a working or protect card in 1:N protection schemes, where N <= 2.
Caution
When a protection switch moves traffic from the DS3/EC1-48 working/active card to the DS3/EC1-48
protect/standby card, ports on the now active/standby card cannot be taken out of service. Lost traffic
can result if you take a port out of service, even if the DS3/EC1-48 standby card no longer carries traffic.
3.7.1 DS3/EC1-48 Slots and Connectors
For SONET applications, the DS3/EC1-48 card requires an HD shelf (15454-SA-HD) and EIA (UBIC,
MiniBNC); Software Release 5.0 or greater; and XC10G or XC-VXC-10G cards.
Note
The DS3/EC1-48 card supports an errorless software-initiated cross-connect card switch when used in a
shelf equipped with XC-VXC-10G and TCC2/TCC2P cards.
You can install the DS3/EC1-48 card in Slots 1 to 3 or 15 to 17 on the ONS 15454, but installing this
card in certain slots will block the use of other slots.
Table 3-9
shows which slots become unusable for
other electrical cards when the DS3/EC1-48 card is installed in a particular slot.
Caution
Do not install low-density DS-1 cards in the same side of the shelf as DS3/EC1-48 cards.
