UNIT WARNINGS
(Top+Bottom lines of disp')
Warning: TX CARRIER IS MUTED as power
outage, CARRIER: 1=Restore 2=Mute
Warning: Int' temp <nn>C, Tx CARRIER
WILL MUTE outside operating range 0-60C
Warning: 10MHz Reference clk in failed,
IF & Clocks switched to int' 1PPM ref.
TX TRAFFIC FAULTS
(Top line of display)
Tx Warn: Reconfiguring Tx path
Tx Fault: <line> off, terr <DTE/DCE> not
ready
Tx Fault: <line> off, nothing to send
Tx Fault: No clock from interface
Tx Fault: Data input is all ones (AIS)
Tx Fault: No Incoming Octet Timing
P300H
Description / Cause / Notes
Unit Warnings: Deferred alarm relay only
The Tx carrier is set to mute after a power fail. The power has failed and returned and the operator
is offered the option to restore the Tx carrier status to ON. The Tx carrier is set under Change, Tx,
Mod, Carrier
This message refers to the internal unit temperature, Check the modem vent slots are clear and
the rear fan has not failed. This Tx Mute may be disabled, see Fault Mode = 8 in Appendix E
The station clock, set to 10MHz, has been selected as the reference the Tx & Rx synthesisers, but
it has failed. Check the signal applied to the station clock port.
Tx Traffic Faults: Tx OK LED Off and Tx Traffic (prompt) relay.
The modem is reconfiguring the Tx path (after a user parameter change).
<line> depends on the interface in use (eg RS422 DCE="TR", V.35="DTR"). This is a DC co ntrol
line which is used to indicate the terrestrial equipment is functioning properly. The <line> switching
off may be user set to cause this fault or be ignored (Change, Terr-Int, Control Lines).See note 5.
<line> depends on the interface in use (eg RS422 DCE="RS", V.35="RTS"). This is a handshake
line which is used to indicate the terrestrial equipment has data to send. The <line> switching off
may be user set to cause this fault or be ignored (Change, Terr-Int, Control Lines). The Modem can
be set to mute the Tx carrier if this line is off (Change, Tx, Mod, Carrier). If carrier is set to mute
when this line is off but this line is set to ignore, then there is no alarm when this line mutes the
carrier. See note 5
The modem is set to use the "Tx Clock In" (Change, Tx, Clocking), but no clock is being provided.
The clock generation will use the internal clock as a backup to maintain the carrier and any
framing/ESC integrity. Check the data connector is attached and for activity on the clock input lines
The data supplied to the modem is all ones (AIS). This is normally used to indicate an upstream
equipment fault, it is not a modem fault. See note 4
This message is only displayed if a 64kbps G.703 card is fitted. It indicates the card has detected
that there is no incoming octet timing on the G.703 signal. The monitoring of this octet timing may
be enabled and disabled with Change, Terr-Int, Card Specific.
