LCR COS Priority
A station should be assigned a class of service for LCR. The LCR COS can be between 0 and 6,
with 0 being unrestricted and 6 being the most restrictive. Within the time period route List
table, line groups are given an LCR COS Priority assignment between 0 and 6.
A station using LCR is able to use only those CO (outside) line groups with a priority
assignment of equal or higher value than the station’s LCR Class of Service (e.g.,...

period to choose in the weekly schedule. The weekly schedule is then used to determine the
time period route list in the Route List Table to use for routing the call for a particular day of
the week. Times are entered in the 24-hour format.
