3.4.6 DS1-14 and DS1N-14 Port-Level Indicators

3.4.6 DS1-14 and DS1N-14 Port-Level Indicators

You can obtain the status of the DS1-14 and DS1N-14 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.
3.5 DS1/E1-56 Card
Note For hardware specifications, see the “A.5.3 DS1/E1-56 Card Specifications” section on page A-19.
The ONS 15454 DS1/E1-56 card provides 56 Telcordia-compliant, GR-499 DS-1 po rts per card, or
56 E1 ports per card. Each port operates at 1.544 Mbps (DS-1) or 2.048 Mb ps (E1). The DS1/E1-56 card
operates as a working or protect card in 1:N protection schemes, wher e N <= 2. The DS1/E1-56 card can
be used with the XCVT, XC10G, or XC-VXC-10G cross-connect cards.
Note The DS1/E1-56 card does not support VT-2 (virtual tributary-2) circuit creation on E1 ports.
Caution When a protection switch moves traffic from the active (or working) DS1/E1-56 card to the standby (or
protect) DS1/E1-56 card, ports on the now standby (or protect) card cannot be moved to Out of Servi ce
state. Traffic is dropped if the ports are in Out of Service state.

3.5.1 DS1/E1-56 Slots and Connectors

For SONET applications, the DS1/E1-56 card requires a high-density (HD) shelf (15454-SA-HD),
UBIC EIA, and Software Release 6.0 or greater.
Note The UBIC-H EIA supports the termination of both DS-1 and E-1 signals when used with the appropriate
cables. The UBIC-V EIA only supports the termination of DS-1 signals.

Green (Active)
Amber (Standby)
The green/amber ACT/STBY LED indicates whether the card is operational
and ready to carry traffic (green) or in standby mode (amber).
Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,
or high BERs on one or more card ports.
