Technical Reference Guide
Power requirements
The NTAK79 obtains its power from the backplane, drawing maximums of 2
amps on +5 V, 50 mA on +12 V and 50 mA on -12 V.
Off
The NTAK79 2MB PRI is not in a disabled state. The
OOS LED will be red.
RED
On (Red)
A red alarm state has been detected. This represents
a local alarm state of:
Loss of Carrier (LOS)
Loss of Frame (LFAS), or
Loss of CRC Multiframe (LMAS).
Off
No red (local) alarm.
YEL
On (Yellow)
A yellow alarm state has been detected. This
represents a remote alarm indication from the far
end. The alarm may be either Alarm Indication (AIS)
or Remote Alarm (RAI).
Off
No yellow (remote) alarm.
LBK
On (Green)
2MB PRI is in loop-back mode.
Off
2MB PRI is not in loop-back mode.
CC
On (Red)
The clock controller is switched on and disabled.
On (Green)
The clock controller is switched on and is either
locked to a reference or is in free run mode.
Flashing (Green)
The clock controller is switched on and is attempting
to lock (tracking mode) to a reference. If the LED
flashes continuously over an extended period of
time, check the CC STAT in LD60. If the CC is
tracking this may be an acceptable state. Check for
slips and related clock controller error conditions. If
none exist, then this state is acceptable, and the
flashing is identifying jitter on the reference.
DCH
On (Red)
DCH is equipped and disabled.
On (Green)
DCH is equipped and enabled, but not necessarily
established.
Off
DCH is switched off.
