Credit Limit
About credit 
limit
As the attendant, you can control credit limit on a 
per-station basis to regulate calling privileges for 
cash-paying customers. Your facility can choose from 
three versions of the credit limit feature as follows:
Table 2-2  Summary of credit limit types
Credit Limit 
Feature
Definition
Trunk disconnect
Trunk disconnect limits calls from a 
credit-limit station to a certain 
duration. Calls that exceed the 
duration are automatically 
disconnected. This method is 
intended for highly restrictive 
environments (e.g. prisons or 
businesses that limit usage on certain 
phones).
Lookahead credit
The lookahead option pre-calculates 
a charge and corresponding 
maximum call duration for each call 
type. Calls are automatically 
disconnected when the current credit 
value is exhausted. A warning tone is 
sent to the caller 60 seconds before a 
call is disconnected.
Positive value
The positive value credit limit never 
disconnects a call in progress. 
However, the station is not allowed 
to begin the call, unless the credit 
value is above zero.
