Rx ABCD * * * * * * F F 0 * F F F F
F F F F F F F F F F Time slot that bypasses between port 0 and 1 carry Channel Associated
Signaling (CAS). CAS signaling comprises four bits: Bit A, C, C and D. This
line shows CAS signaling for each voice channel by which you can determine
channel status based on the current CAS value. It is a debug aid. Channels
marked with an asterisk (*) are read as follows:
• 1 ‐ On the displayed port, timeslot 10 is used for data and is marked with
an asterisk (*)
• 2 ‐ On the complementary port, (the other port of the card) timeslots 1
through 6 are used for data.
• 3 ‐ All time slots not used for data on neither port are bypassed between
the two ports and their CAS ‐displayed.
T3 0/1/0 is up T3 controller in slot 0 is operating. The controllerʹs state can be up, down, or
administratively down. Loopback conditions are shown as (Locally looped) or
(Remotely Looped).
Applique type Channelized or Non Channelized.
Alarms detected Any alarms detected by the controller are displayed here. Any active alarm
will bring the controller to Oper Down state. The YELLOW LED beside the port
connector is ON for all physical alarms, but stays OFF for loopback modes.
The following alarms are listed:
• Transmitter is sending remote alarm (TxRAI).
• Transmitter is sending TxAIS.
• Receiver has loss of signal (LOS).
• Receiver is getting RxAIS.
• Receiver has loss of frame(LOF).
• Receiver has remote alarm (RxRAI).
• Receiver has no alarms (NONE).
• Controller is set into a Payload Loop back (PayLd) from the network.
• Controller is set locally or from the network into any type of Loopback
(LOOP) from the network.
Network Line Loopback • None ‐ normal operation
• DS3 Line Loopback (applicable for C‐bit parity only)
MDL transmission is disabled Status of the maintenance data link (either enabled or disabled).
