TeleSoft International is the original developer
of the TsLink3 range of high performance WAN protocols including
SIP, ISDN BRI and PRI, QSIG, CAS E1 R2, T1 RBS, AO/DI, ML-PPP, Frame
Relay, X.25, and also a range of hardware reference designs. TsLink3
protocol source code is exceptionally well engineered - tightly
coded for performance and compact footprint, with a quality that
delivers rock-solid stability.
TeleSoft's foundations go back to 1986 when the
first ISDN stack was released. Since then TeleSoft's protocols have
been proven in use by more than 200 customers worldwide. Pre-loaded
C source code and comprehensive documentation is provided to give
OEMs a rapid path to market-ready WAN products.

CompactSIP 3GPP/IMS, IETF, TsGATE
CompactSIP is a new highly efficient implementation of the SIP standard
with an exceptionally modular and scalable architecture that can
support compact embedded environments with a footprint as small
as 80Kb, while scaling up to support rich, full-featured terminal
implementations with a footprint typically less than 300Kb. There
are two versions of CompactSIP plus a SIP/PSTN Gateway:
IETF CompactSIP - a
richly featured yet very compact and scalable SIP stack with extensive
support for IETF standard SIP RFCs. It is ideally suited for embedded
applications including IP phones, PDAs, ATAs & Telematics.
3GPP/IMS CompactSIP
- developed in partnership with the world's leading mobile service
provider, it supports the needs of manufacturers developing 3G handsets,
3G datacards, 3G mobile platforms and 3G chipsets. It provides a
3GPP/IMS compliant software stack that supports the key 3GPP authentication
and security standards plus the required IETF SIP RFCs.
TsGATE - an integrated software
SIP to PSTN Gateway that works directly with CompactSIP to translate
the packetized messages on IP networks to the TDM messages used
on the digital PSTN networks.
ISDN BRI/PRI, DSS1, LAPD
TsLink3 Basic Rate and Primary Rate ISDN source code stacks are
amongst the most proven and feature-rich available today. In addition
to DSS1, AutoSPID, Autoswitch Detection, NFAS, and D-Channel Backup,
a wide range of conformance tested worldwide switch variants is
available. Full NT and TE side support is included. Q.921 LAPD and
Q.931 LAPB can be licensed either individually or as an integrated
stack.

ISDN & QSIG Supplementary Services
TeleSoft provides a rich set of Voice Supplementary Services (also
referred to as Q.932) for both QSIG and ISDN TE and NT sides. Customers
can license ISDN Supplementary Services for Lucent 5ESS, US National
ISDN-1 and National ISDN-2, and EuroISDN TBR3 (EuroISDN NET3).

T1 RBS / E1 CAS R2
TeleSoft provides a full range of DS1 signaling solutions by providing
T1 Robbed-bit Signaling (RBS) source code library and E1 R2 Channel
Associated Signaling (CAS) source code library, device drivers and
related software to accelerate development and conformance testing
of in-band signaling products. TeleSoft supplies a full implementation,
including Facilities Data Link (FDL) in source code.

QSIG/PSS1
TeleSoft's QSIG/PSS1 source code is a full-featured implementation
available as individual modules -- QSIG Basic Call (QSIG BC), QSIG
General Functional Procedures (QSIG GF), or QSIG Supplementary Services
(QSIG SS) or as an integrated stack.

AO/DI
TsLink3 Always On/Dynamic ISDN (AO/DI) consists of an AO/DI manager
tightly integrated with well-proven TsLink3 ML-PPP, BACP, and X.25
source code to provide a fully featured always-on, bandwidth-on-demand
service.

ML-PPP / DSL
TeleSoft's customers have used the TsLink3 ML-PPP source code library
to gain additional bandwidth on demand without compromising standards-based
interoperability or their development schedule. Recently, ADSL device
manufacturers have "bonded" two or more ADSL streams by
using TeleSoft's Multi-Link PPP protocol stack to multiply the bandwidth
of a single ADSL connection. TeleSoft also provides PPPoE and PPPoA,
as well as other DSL source code like MPoA.

Frame Relay / X.25
TeleSoft International provides protocol stacks, source code libraries,
and device drivers to accelerate development and conformance testing
of X.25, Frame Relay, V.120 and other WAN protocol stacks. TeleSoft
International provides the fastest path to market-ready ISDN products
for manufacturers worldwide. Both TsLink3 Frame Relay Permanent
Virtual Circuits (PVCs) and Frame Relay Switched Virtual Circuits
(SVCs) are available for license.

 Wrote
the Book...
TeleSoft's founders have been influential in protocol development
since 1982, and all are still with the Company. Charles K Summers,
VP of Engineering, an acknowledged expert on WAN protocols, has
written three popular books on ISDN and ADSL, the first of which
became a widely acknowledged reference work:
· ISDN: Implementor’s Guide
· ISDN: How to get hi-speed connection to the Internet
· ADSL: Standards, Implementation and Architecture
TeleSoft has been helping customers build successful
products since 1986. Let them help make your project a success!
