Last Number Redial (LNR)
The function of the on-chip LNR store is to automatically retain a manually dialled
number for redialling later. The capacity of the store is 24 digits. If a number longer
than 24 digits is dialled, redialling will be inhibited.
The LNR store has two features designed to assist the user,viz: Moving Cursor
Facility and Mixed Mode Dialling.
Moving Cursor Facility:
This facility is provided to aid use in PABX applications,
where the user must first dial an access digit or digits, and then wait for a second dial-
tone before continuing dialling.
If the first digit(s) of a new number dialled match the contents of the LNR store, then
pressing LNR (redial button twice) will dial out the remaining digits. If there is a
mismatch in the number then redial is inhibited until the next on-hook and the LNR
store will contain the new number. If the user manually dials the first digit(s) matching
those stored in LNR, and then goes on-hook, the whole contents of the store will be
retained.
Mixed Mode Dialling:
In the case of a call which starts in LD mode and is switched
by the user (via the∗ or # keys) to DTMF mode, only the digits dialled in LD mode
will be retained. Provided that the number of digits dialled in LD mode does not
exceed 24, the digits will be retained regardless of the number of DTMF digits
entered subsequently.

Repertory Dialling (10 Numbers)
The SA545 provides 10 repertory stores each of which is 24 digits in length. Any
attempt to store a number greater than 24 digits, will cause the store to be
automatically cleared. No further digits will be accepted into the store until the whole
programming operation is repeated.
