actual number. Spaces used in this way will have the
following results;
0 or 1 space speaker always off
2 spaces speaker on when dialing only
3 spaces speaker always off
4 spaces speaker on during incoming
calls only
If no “T” or “P” is used, the speaker will default to off.
Special characters provide the following functions:
, Provides 2 second (default) delay
W Wait for dial tone
T Tone (touch tone/pushbutton) type phone
P Pulse (rotary) type phone
SPAC Controls speaker when placed
immediately after T or P, otherwise no
function.
Notes:
1. The T or P should be the lead character when used.
Usually for “T” type systems the T can be omitted. “P”
must be used for rotary systems.
2. Use “,” (delay) or “W” (wait for dial tone) with phone
systems that take a while for the dial tone, particularly
for those that require a 7, 8, or 9 first to get a line.
3. Avoid overuse of special characters. Many systems
require no special characters at all.
MODEM INIT STRING (PGDN FROM PHONE #’s)…
Used to set modem initialization string per modem
manufacturer’s recommendations.
SPECIAL FUNCTION CIRCUIT MAPPING
Applies to MDM100 and MIST only. This feature allows
the local controller’s time clock circuits to be activated
by the MDM100 or MIST. Special function bits 1-32 are
issued by the master and are received by the LMD
through the system comm port.
PG DWN… For Special functions 9- 24…..
-Circuit specifies which clock ckt function gets activated
by the special function bit.
-Delay specifies how long the LMD will wait to activate
the specified function after receiving the bit. Delays can
vary from intersection to intersection to provide
sequenced operation such as route pre-empt below.
Special function circuits could, for example, be used for
“route pre-emption” whereby a series of local
controllers are pre-empted by the master. By utilizing
the time delay feature in varying amounts at each
intersection, a sequenced pre-emption can be
performed. Intersections within the system that are not
associated with the route simply do not have a ckt
assigned to the special function bit.
SYSTEM MAP CICUITS (For MDM100 only)
This programming area defines which phases will be
displayed on the system wide map at the Central Office
Monitor. The System Wide Map Signal Assignments
are sent back to the Central Office Monitor via the
MDM100.
From PROGRAM/READ, selection 8…COMM SET-
UP…then selection 4….SYS MAP PHASES….
TBC BACK-UP DELAY…
TBC is the back-up mode for comm interconnect. The
back-up delay defines how long the LMD will wait to
implement the TBC back-up after carrier (comm) is lost
(which may only be brief).
REPORTS
The LMD is capable of logging a number of significant
events by time and date. These logs can then be
assigned to a specific schedule and, in the direct dial
mode automatically called in to Central. Reports can
also be uploaded (only) upon request.
