Chapter 1 Solution Overview
Solution Features
Information Service Calls (900 and 976)
Information service calls (ISC) provide a variety of announcement-related services on a national or local
basis. The two general categories of this service are Public announcement services (PAS)-Weather,
sports, horoscope, and so forth, and Media stimulated calling (MSC)-Telephone voting, radio station
call-ins, and so forth. National calls are dialed as 1-900-xxx-xxxx and local calls are dialed as
NPA-976-xxxx.
N11 support (311, 411, 611, 711, 811)
The N11 services supported by the Cisco BTS 10200 Softswitch are:
• Nonemergency Services (311)
• Directory Assistance (411)
• Repair Service (611)
• Telecommunications Relay Services (711)
• Local Billing Services (811)
Operator Services Subscriber Access (0,00,0+,01+,CAC+0+,CAC+01+)
Operator services is a call-processing function whereby callers can access either a live operator or an
automated function to complete calls or gain access to information. The service provider can provide this
feature or outsource it to a third-party vendor. Some additional functions accomplished by operator
services include automatic call distribution, billing detail recording, and information retrieval. The
numbers commonly used to access operator services are:
• 0—Local operator support
• 00—Operator support outside the “local” calling area, using a presubscribed interexchange carrier
(PIC)
• 0+ area code and number—Operator support when the destination number is known (that is, for
collect calls, calling card calls, person-to-person calls, and so forth), using PIC
• CAC+0+—Operator services, using a dialed carrier access code (CAC)
• 01+CC+NN—international operator services, using PIC
• CAC+01+CC+NN—International operator services, using a dialed CAC
Operator Services Busy Line Verification and Operator Interrupt
Busy line verification (BLV) service permits the user to obtain operator assistance to determine if a
called line is in use. The user dials 0, waits for the operator to pick up the line, and requests BLV service.
If not prohibited in advance by the party on the called line, the operator interrupts the conversation in
progress and relays a message. At the user’s request, the operator has the option to directly connect the
user to the called line.
Toll Free Services
The purpose of toll free services is to have the called party, rather than the calling party, charged for the
call. These calls are prefixed with the 1+800 or 1-8nn service access codes. The seven digits following
the 800/8nn codes are used for routing the call. The Cisco BTS 10200 Softswitch communicates with a
database called the toll-free database service, which contains information for routing the call. The
database service provides information about the network service provider selected to complete the call,
and information for translating the toll-free number to a specific 10-digit directory number (DN).
