2-9. General Operating Procedures.
Operation of the TD-1337(V)/G consists of performing the procedures described in a through e below.
Operator functions are performed using the display and keyboard on the TD-1337(V)/G and the routines
in this chapter.
a. Power Turn-On. When the POWER ON/OFF circuit breaker is set to ON, the TD-1337(V)/G is auto-
matically operating in the same mode that it was in when it was turned off. When the TD-1337(V)/G
is turned on, it is possible that the ALARM horn will sound and one or more of the ALARMS indicators
will light. The turn-on procedures tell the operator how to evaluate these alarm conditions. If there are
no configuration requirements, or mode change required, the TD-1337(V)/G is operationally ready to process
user traffic if it is in a memory 1 or memory 2 mode of operation.
b. Orderwire Calls. A V1 or V2 model has the capability to answer or make orderwire calls using
the Vinson or H-250 handsets. The Vinson, H-250, or ANDVT equipment can be used with a V3 or V4
model. The types of orderwire used are determined by the network configuration in which the TD-1337(V)/G
is operating. If the TD-1337(V)/G is in the inactive or TD-976 mode of operation, the orderwires cannot
be used.
c. Monitoring for Faulty Operation. The ALARM horn sounds and one or more of the ALARMS indicators
light when a faulty condition is detected by the TD-1337(V)/G. Also, power faults are identified when the
POWER AC and/or DC indicators are off. Any time a faulty condition occurs, refer to the troubleshooting
procedures in chapter 3.
d. System Mode Change. You will only change the system mode of operation when authorized to
do so. As described in the system mode change routine, certain alarm conditions can occur and should
be evaluated as directed in the routine.
e. Configuration Routines. The configuration routines in section IV are used to enter configuration data
in the NVM only when authorized. When performing a configuration routine, you will be provided with
the required data. Authority that originates the operating configuration will provide the necessary configuration
data. To assist you in determining if you have all the data necessary to perform a given routine, the
data requirements for each routine are listed at the beginning of each routine. Use of the keyboard and
a description of the messages that can be displayed in the routines are in section I of this chapter.
Chapter 1 contains overall descriptions of the operating and configuration routines that you can use in
the operation of the TD-1337(V)/G.
