2.4 USING LCR WITH CALLER ID
It is necessary to have LCR programmed on systems with Caller ID to enable certain
features with a DIAL/REDIAL option to be used. This is because the 10 digit CID
number format provided by the Central Office always contains the area code. This area
code must be stripped off in the LCR modified digits section to allow a local number to
be correctly dialed. To make this task easier, the system inserts a 1 in front of the
received digits. This makes it look like a normal 11 digit telephone number so LCR can
process the number and modify the digits.
For example, if the system is located in the 305 area code, the LCR digit table points
the entry 1305 to a modified digits entry that deletes the first four digits of the CID
number. Of course, this is a much simplified LCR scheme. As there are long distance
calls to be made within the home area code, additional entries are required to identify
these calls. This is illustrated in the sample table for MMC 710 below where entries 013
to XXX are the local area code (305 in the previous example) followed by the local CO
prefixes. This will tell the system which calls need to have the first four didits stripped
off using the modifiy digits table.
In MMC 710, program the following entries:
