750.1 GENERAL
This section is intended to provide the user with a
complete understanding of how to program the LCR
subsystem. It is strongly recommended that this
section be read in its entirety BEFORE attempting the
actual programming.
This will allow more efficient
programming.
750.2 HOW TO USE THIS SECTION
The remainder of the programming section (Section
750) is divided into the following subsections:
PROGRAMMING SYSTEM NPM FOR LCR (Section
750.3) describes in detail, the related programming
areas within the system memory blocks which are
required to properly implement the LCR feature.
LCR PROGRAMMING CONSTRUCTION (Section
750.4) provides a basic description of how the LCR
subsystem is configured within the Electra Mark11
Digital Telephone system, and provides an explanation
of the various parameters of the LCR data
programming.
i
INITIALIZING THE PC-8300 (Section 750.5) explains
-
how to initialize the PC-8300 portable computer in
preparation for LCR programming and how to set it up
to allow the automatic execution of the LCR data
program upon power up of the PC-8300.
PROGRAMMING LCR DATA (Section 750.61 explains
how data is entered into the LCR program via the
PC-8300.
INPUT OF DATA (Section 750.7) explains the general
flow of programming and provides detailed examples
on how the various sections of the program are
accessed.
EXPLANATION OF LCR COMMANDS (Section
750.8) describe each command and gives examples of
their use.
ERROR MESSAGES (Section 760.91 explains the
various possible error messages as well as the reasons
why they occur and possible solutions for each of them.
750.3 PROGRAMMING SYSTEM MEMORY
FOR LCR
1. Programming System Data
Prior to programming LCR data using the
programming computer, system data relating to
LCR must be programmed from a programming

Keys.
IMPORTANT NOTE
Before going into system data programming, make
sure the switch SW1 on the LCR-E ETU is turned ON
for battery backup of system data.
NOTE: Memory Blocks 2C1,2C2 and 2C3 may have to
be referenced for proper LCR operation.
Incoming Tie lines can use tandem access to seize
outgoing trunks. Economy of service can be achieved
by assigning LCR to the tandem ports associated with
those Tie lines. This allows the system to route the
tandem calls to the most economical line available.
A.
B.
Override of LCR
Override can be assigned by class of service on
a station basis. When it is programmed to a
station, LCR does not apply to the station.
LCR 1 Plus Dialing Assignment
LCR 1 plus dialing assignment must be
programmed if the location of the system is a 1
plus dialing area. This assignment is on a
system basis,
