2. When the CO/IP line used for the original call is busy, the system will select an idle line from
the same CO/IP line Group to place the call.
3. Using Last Number Redial will cancel Automatic Called Number Redial if active.
4. The LNR buffer is not stored in non-volatile memory and is erased if power to the system is lost.
5. Manually dialing a Flash during an outgoing call will cause only those digits dialed after the

2.50 LCR (LEAST COST ROUTING)
Description
The LCR Tables are employed to define appropriate routing for outgoing calls based on the dialed
number. Generally, the LCR Tables are structured to define the Least Cost Route for Long Distance
calls.
User dialed digits are compared to table entries and modified based on time of day, day of week, and
assigned routes. There are four LCR Tables: LCR Control Attributes, LCR Leading Digit, LCR Digit
Modification and LCR Initialization Tables.
LCR Access modes are assigned in the LCR Control Attributes Table. These modes define the
manner in which the user accesses the LCR function. LCR may be disabled or one or more of the
three access modes can be allowed to access LCR. The basic modes are:
1. Internal LCR
If the user dialed digits match an Internal LCR code in the LDT (Leading Digit Table), a CO/IP path is
selected and digits are modified using the DMT (Digit Modification Table).
2. Loop LCR
If the user dials 9 (the 1
st
available CO line access code) or presses a {POOL} or {LOOP} button to
place a call, the Loop LCR mode is accessed. Dialed digits are compared to the Loop LCR codes in
the LDT; the system will seize a CO/IP line from the assigned CO/IP Group and sends digits from the
DMT.
3. Direct CO LCR
If the user selects a {
CO}/{IP} or {CO/IP GROUP} button, the Direct CO LCR mode is accessed. If the
user-dialed number matches a Direct LCR code in the LDT and the seized CO/IP line belongs to the
assigned Direct CO LCR group, the system will send digits modified based on the DMT.
