Solution Features
NPA Split Support
When DNs are exhausted within an NPA, an additional NPA is assigned to the region. The new NPA may
be allocated as an overlay over the existing NPA, in which case there is no major impact to the Cisco
BTS 10200 Softswitch. However, when the new NPA is assigned based on a geographical split of the
region, there are significant impacts. The assignment of the new NPA based on a geographical split is
referred to as split-NPA.
Legal Interception (CALEA)
The Cisco BTS10200, as well as the Cisco uBR7246VXR and the Cisco MGX 8850 support the
PacketCable Electronic Surveillance Specification. These products, in conjunction with a third party
mediation device, provide a MSO with the ability to comply with the requirements of the
Communications Assistance for Law Enforcement Act (CALEA) for providing call detail information
or call detail/call content information to law enforcement for a specific DN in response to a court order.
Other Network Features
Other network features on the Cisco BTS 10200 Softswitch consists of Dialing Parity, Toll-Free
Database Service and Trunk Testing.
Dialing Parity (IntraLATA Toll Presubscription)
Dialing parity—also known as intraLATA toll presubscription—allows subscribers to select a
telecommunications company for intraLATA calls (local toll calls) in the same way they select a long
distance provider. With dialing parity, subscribers are able to dial the number they want and have a
preselected carrier—a CLEC, ILEC, or a long distance carrier—automatically handle the call if it is a
local (intraLATA) toll call. Preselecting a local toll carrier eliminates the need for dial-around service
for local toll calls (101XXXX numbers).
Toll-Free Database Service
The Cisco BTS 10200 Softswitch provides the ability to translate inbound/outbound 800 numbers at the
FS using a local 800 database. The 800 service supports the following features:
• Origin dependent routing
• Time of day routing
• Percentage based routing
• Information digit-based screening
• Black/white list screening
The Cisco BTS 10200 Softswitch also supports optional DNIS service. In an 800 DNIS service, when a
call is terminated to a PBX (call center), 4 digits are outpulsed to the PBX to identify the originally
dialed 800 number. In case of custom DNIS, up to 22 digits can be outpulsed with additional information
such as:
• Original 800 number dialed
• Automatic number identification (ANI)
• Originating line information of the calling party
