2-11. System Mode Change Routine.
Perform the following routine to change the system mode of operation. If you are placing the TD-1337(V)/G
in the preliminary mode, you require the configuration data described in a below. The step-by-step procedures
for changing the system mode of operation are in b below.
NOTES
Do not perform this procedure without authorization. If a mode
change makes TD-1337(V)/G operate in a configuration that is
not compatible with other TD-1337(V)/G's in the network, user
traffic flow is interrupted.
Orderwire configuration data must be in NVM before TD-1337(V)/G
can be placed in preliminary mode of operation.
Following configuration data must be in appropriate NVM memory
area before TD-1337(V)/G can be placed in memory 1 or memory
2 mode of operation.
1. Orderwire configuration.
2. Local mux configuration data.
3. Configuration data for each active demux.
a. Data Required for Preliminary Mode Change. The data listed below is required to place the local
TD-1337(V)/G in the preliminary mode. This data is provided by the authority that originated the configuration.
In addition to the local TD-1337(V)/G, the composite rates of the SG'S from the remote TD-1337(V)/G's
in the network are required. These are the composite rates assigned to the active demux's in the local
TD-1337(V)/G. A nodal (V1 or V3) can use up to four demux's and a non-nodal (V2 or V4) uses only
demux No. 1.

b. Procedures for Change System Mode Routine. Perform the following procedures to change system
mode of operation.
NOTES
q When a message is displayed that you do not understand, go
to paragraph 2-6. All messages that can be displayed on TD-
1337(V)/G are listed in alphabetical order. The operator action
associated with each display is described in the paragraph.
q Start with step 1 and perform the action in the procedures as
directed. Messages that appear on the display are shown in bold
type.
