Page 1482 of 3156 FCC Compliance for DID Answer Supervision
553-3001-306 Standard 10.00 January 2002
Feature Group D and Japan DID trunks
Feature Group D trunks and Japan (JPN) DID trunks are not affected by this
feature.
ISDN trunks
Both incoming and outgoing Integrated Services Digital Network (ISDN)
trunks are affected by this feature.
• For ISDN incoming DID trunks, the connect message is returned when
answer supervision is returned or when the end of dial timer expires.
• For ISDN outgoing trunks, the end of dial timer is added to the protocol
to simulate the EOD timer when a connect message is not returned from
the far end; the Meridian 1 generates a pseudo-answer supervision to
send to the incoming trunk.
Intercept
Recorded Announcement
With this feature, incoming DID calls that are intercepted to a Recorded
Announcement (RAN) are provided with answer supervision.
Operating parameters
Allowing Meridian 1 equipment to be operated in such a manner as to not
provide proper answer supervision signaling is in violation of Part 68 rules.
This equipment returns answer supervision signals to the public switched
telephone network (PSTN) when:
• answered by the called station
• answered by the attendant
• routed to a Recorded Announcement that can be administered by the
Customer Premises Equipment (CPE) user, and
• routed to a dial prompt.
This equipment returns answer supervision on all DID calls forwarded back
to the PSTN. Permissible exceptions are when:
• a call is unanswered
