Preprogrammed Dialer Features
When you program emergency numbers or make test calls to emergency numbers using Sie-
mens products with preprogrammed dialer features, stay on the line and briefly explain to the
dispatcher the reason for the call before hanging up. Perform these activities in off-peak hours,
such as early morning or late evening.
Connecting Off-Premises Station Facilities
Customers who intend to connect off-premises station (OPS) facilities must inform the telecom-
munication company of the OPS class for which the equipment is registered and the connection
desired.
Direct Inward Dialing Answer Supervision
Customers operating any Siemens system discussed in this section without providing proper
answer supervision are in violation of Part 68 of the FCC rules.
Each Siemens system discussed in this section returns proper answer supervision to the
●
public switched telephone network (PSTN) when DID calls are:
– Answered by the called station.
– Answered by the attendant.
– Routed to a recorded announcement that can be administered by the customer.
Each Siemens system discussed in this section returns proper answer supervision on all
●
DID calls forwarded to the PSTN. Permissible exceptions are when:
– A call is unanswered
– A busy tone is received
– A reorder tone is received
Equal Access Requirements
Call aggregators, such as hotels, hospitals, airports, colleges and universities, and so on, must
provide the end user with equal access to the carriers of the user's choice. The current equal
access codes (also known as carrier access codes [CACs]) are 10xxx and 101xxxx, and 800/
888 and 950, where xxx or xxxx represents the carrier identification code.
To select the carrier of choice for a call, the user dials the equal access code before dialing the
called party number. Equal access is also obtained by dialing the 800/888 or 950 number of the
carrier of choice.
