Nortel Networks Circuit Card 311 - Manual (Page 171)

Physical description 171
The Lineside T1 card mounts into any two consecutive IPE slots. The card
consists of a motherboard and a daughterboard. The motherboard circuitry
is contained on a standard 31.75 by 25.40 cm. (12.5 by 10.0 in) printed
circuit board. The daughterboard is contained on a 5.08 by 15.24 cm (2.0 by
6.0 in) printed circuit board and mounts to the motherboard on six standoffs.
The Lineside T1 card mounts into any two consecutive IPE slots. The
card consists of a motherboard and a daughterboard; both are printed on
standard circuit board.
In general, the LEDs operate as shown in Table .

LED State Definition
On (Red) The NT5D14AA card either failed its self-test or it hasn’t yet
been configured in software. STATUS
Off The card is in an active state
On (Red) A red alarm has been detected from the T1 link. (This
includes, but is not limited to: not receiving a signal, the
signal has exceeded bit error thresholds or frame slip
thresholds.) RED
Off No red alarm exists.
On (Yellow) A yellow alarm state has been detected from the terminal
equipment side of the T1 link. If the terminal equipment
detects a red alarm condition, it may send a yellow alarm
signal to the Lineside T1 card (this depends on whether or
not your terminal equipment supports this feature). YEL
Off No yellow alarm.
On (Red) The card detects whether tests are being run or that alarms
are disabled through the Man-Machine Interface. The LED
remains lit until these conditions are no longer detected. MAINT
Off The Lineside T1 card is fully operational
Card connections
The Lineside T1 card uses the NT8D81AA Tip and Ring cable to connect
from the IPE backplane to the 25-pair amphenol connector on the IPE I/O
input/output (I/O) panel. The I/O panel connector then connects directly
to a T1 line, external alarm, and an MMI terminal or modem using the
NT5D13AA Lineside T1 I/O cable available from Nortel.
