3.9.5 DS3XM-6 Port-Level Indicators
You can find the status of the six DS3XM-6 card ports by using the LCD screen on the ONS 15454
fan-tray assembly. Use the LCD to quickly view the status of any port or card slot; the screen displays
the number and severity of alarms for a given port or slot.
3.10 DS3XM-12 Card
Note For hardware specifications, see the “A.5.8 DS3XM-12 Card Specifications” section on page A-23.
The DS3XM-12 card, commonly referred to as a transmux card, provides twelve Telcordia-compliant,
GR-499-CORE M13 multiplexing ports. The DS3XM-12 converts up to 12 framed DS-3 network
connections to 12 x 28 VT1.5s.
3.10.1 Backplane Configurations
The DS3XM-12 card has 12 framed DS-3 physical ports (known as “ported” mode). The card also
supports a maximum of 12 “portless” DS3-mapped STS1 interfaces depending on the type of
cross-connect used. Each physical port corresponds to two portless ports. If a circuit is provisioned to a
physical port, its associated portless pair becomes unavailable and vice versa. See the “11.4 Portless
Transmux” section on page 11-15 for more information.
The DS3XM-12 card is compatible with the XCVT, XC10G, and XC-VXC-10G cross-connect cards.
Note The DS3XM-12 card supports an errorless software-initiated cross-connect card switch when used in a
shelf equipped with XC-VXC-10G and TCC2/TCC2P cards.
Caution During an upgrade of the DS3XM-6 card to DS3XM-12 card, the DS-3XM-12 card (in slots 1 to 5)
encounters an insufficient cable loss of margin when the LBO setting on the DS-3 input ports are set
between 225 to 450 feet cable lengths.

card is operational and in standby in a 1:1 protection group.
