Abstract
When receiving a request from a telecommunications switch (106) for a telephone call to a party, a loop carrier (108) checks for errors and availability in the distribution resources that couple the called party to the digital loop carrier (108). For a distribution resource error or unavailability, the digital loop carrier (108) generates a distribution resource error message that is transmitted to the telecommunication switch (106). The telecommunication switch (106) applies terminating call features for the called party, such as voice mail or call forwarding, in response to the distribution resource error message.
