UMTS Services
The TANDBERG Entrypoint offers a variety of UMTS dial-in
services:
Direct Inward Dialling (DID) – the destination endpoint is •
determined from the dialled number
Interactive Video Response (IVR) – the destination endpoint •
can be selected via touch tones.
TMS Corporate Directory – the destination end point can be •
selected via a search in a TMS phonebook.
Menu – the destination end point or service can be selected •
via a menu.
Security
Secure Access - support XML/SOAP over HTTPS, Web (HTTP) •
encrypted password and the services that can be disabled.
Video Quality
H.263 video compression. •
Audio Quality
AMR, G.711 audio compression •

Interoperability
Worldwide compatibility with standards-based •
videoconferencing systems
Compatible with all available WCDMA H.324M video telephony •
capable handsets supporting DTMF tones.
Management Interfaces
SOAP (Simple Object Access Protocol) is a lightweight protocol
for exchange of information in a decentralized, distributed
environment.
XML (Extensible Markup Language) is a flexible way to create
common information formats and share both the format and
the data on the World Wide Web, intranets, and elsewhere.
This functionality can be used by management systems like the
TANDBERG Management Suite to control the Entrypoint
HTTP Web-interface for system management, call management
such as diagnostics and software uploads
HTTPS Hypertext Transfer Protocol over Secure Socket Layer is
a Web protocol that encrypts and decrypts user page requests
as well as the pages that are returned by the Web server. It uses
Secure Socket Layer (SSL) as a sublayer under its regular HTTP
application layering. HTTPS uses port 443 instead of HTTP port
80 in its interactions with the lower layer, TCP/IP. SSL uses a
40-bit key size for the RC4 stream encryption algorithm, which
is considered an adequate degree of encryption for commercial
exchange.
Network and Features
Call rate of 64 kbit on ISDN side and 768 kbps on IP side for •
each call is supported through the Entrypoint.
Interactive Video and voice Response (IVR). •

The TANDBERG Entrypoint enables sites on IP and UMTS
Handsets to participate in meetings with each other with the
quality and reliability found in all TANDBERG equipment. An
Entrypoint system opens up a wide range of interactive video
and call routing services.
Due to the fixed bandwidth of UMTS video telephony every
call will be limited to 64 Kbits/s. This offers a capacity of 30
simultaneous calls through an E1 PRI, 23 simultaneous calls
through a T1 PRI, or 8 calls through a 4 × BRI. Due to audio
transcoding (AMR to G.711) the bandwidth at IP side is 109
Kbits/s per session, 64 Kbits/s G.711 audio and 45 Kbits/s
H.263 video calling 3G to H.323 or SIP endpoints. For calls
between H.323 endpoints it is possible to set up 60 sessions
between 768 and 192 kbit.
