750.1GENERAL

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.

750.2HOW 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.

position key set. See Figure 700-22 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.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.

B.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,
