PSTN Digital Trunk Support NMS ISDN and NMS Digital CAS for T1 and E1
N
MS Communications’ ISDN and CAS protocol software, part of
the Open Access™ framework, enables any NMS AG or CG Series platform with T1 or E1 connections to interface with ISDN Primary Rate Interface (PRI) switches and with digital chan- nel-associated signaling (CAS) trunks worldwide. NMS offers the broadest digital trunking support in the industry. The Natural Access™ development environment’s line-, protocol-, and switch-independent call control API, Natural Call Control™ (NCC), reduces time to market for international deploy- ments. Downloadable DSP firmware executes the ISDN or CAS protocol onboard, enabling efficient call pro- cessing while offloading the host CPU.
NMS ISDN Features ■ Certified for use in over 20 countries ■ Provides NMS digital trunk platforms with cost-
effective, easy-to-use ISDN PRI connectivity ■ Basic Q.931 Call Control ■ Dialed Number Identification Service (DNIS)
and Automatic Number Identification (ANI) enhance call-routing and application features ■ Sub-addressing feature enables the
sharing of one phone number for multiple extensions/devices ■ User-to-User Information allows information
to be sent about the user to another ISDN site at the time of call set-up, connection, and clearing ■ Higher-layer compatibility functions allow
applications to set outbound call charact eristics (e.g., set type of call to “fax”), check characteristics of inbound calls, and reject incoming calls that do not match specified criteria ■ Support for network-side applications across
all supported variants ■ Multi-layer access to ISDN protocol stack ■ Channelized ISDN (Layer 4) ■ Flexible Layer 3 Messaging API allows appli-
cations to directly control messaging to/from the D-channel ■ Access to LAPD (Layer 2) allows develop-
ment of proprietary network protocols ■ Reports reason for SIT tone
NMS CAS Features ■ Supports worldwide digital protocols, includ-
ing: MFC-R2, European CAS protocols, CAS R1.5, Feature Group D, Australian P2, Ground Start, OPS/OPX, SS5, International wink start protocols, variations of Digital E&M protocols, and European MF Socotel protocol. ■ Trunk protocols are parameterized to cover
many country variants ■ Two-way trunk support enables applications
to support both incoming and outgoing calls uniformly on a dynamic basis ■ Versatile Automatic Number Identification/
Direct Inward Dialing (ANI/DID) digit presen- tation gives high-performance applications the ability to select whether called party, calling party numbers, and call category are returned one at a time or in a block ■ Vari-digits feature allows the application to
answer the call at any point during call setup, for example based on the first three digits of DID information rather than waiting until all address information is delivered by the network ■ Returns billing information to the originator of
a call ■ Selection of whether a call is answered as
a free or billed call on a call-by-call basis (supported by MFC-R2 only) ■ Ability to defer answering or rejecting an
inbound call until the outbound leg of the call has been set up for drop and insert applications ■ Automatic generation of country-specific
call tones ■ Reports reason for SIT tone
PSTN Digital Trunk Support Protocol Product Description NMS ISDN and CAS are a Natural Access extension and are integrated with firmware on the AG and CG platforms. Integration with Natural Access media APIs simplifies high-value application development. Single-slot solutions providing call control, fax, voice, and tone pro- cessing can be developed quickly and cost effectively using a single board. Natural Access supports access to the ISDN protocol stack at multiple layers. The
Natural Call Control API can be used to access ISDN services using standard Natural Access call control. In addition, a single switch- and protocol-independent messaging API interfaces to Layer 3 of ISDN, which enables developers to directly control messaging to and from the D-channel. Applications are developed once and can be deployed internationally by simple runtime configuration. For developers imple- menting proprietary network protocols, access
is also available to LAPD (Layer 2) of the ISDN protocol stack. Low-level CAS call control functions are also provided. These are usually used when the trunk is configured for no call control. NMS boards can be configured with a mix of different CAS and ISDN protocols, selectable during runtime. However, multiple ISDN protocols can only be configured if Natural Call Control is used.

DPNSS is a private network protocol origi nating in the UK before ISDN was an interna tional standard. Although NMS supports 11 feature-rich versions of ISDN, some switches still require DPNSS. NMS DPNSS is offered as a private network protocol version of NMS ISDN, providing the basic call set up, tear down and transfer functions. It also provides some basic additional services such as Dialed Number Identification Service (DNIS), Automatic Number Identification (ANI), and a means of sending transparent Information Elements, which allow sending of information about the user to another DPNSS site. The NMS DPNSS protocol stack can be accessed at multiple layers. The Natural Call Control API can be used to access DPNSS services using standard Natural Access call control. In addition, a single switch- and protocol-independent messaging API inter faces to Layer 3 of DPNSS, enabling develop ers to directly control messaging to and from the D-channel. Applications are developed once and can be deployed internationally by simple runtime configuration.
