UNIVERGE SV8100
Description
H.323 is an International Telecommunication Union (ITU) standard for Packet Based Multimedia
Communication Systems. The UNIVERGE SV8100 can use H.323 to connect to another UNIVERGE
SV8100 system or a third party product.
The feature set is limited. When using H.323, it is not possible to use the advanced networking features. If
these features are required, use IP KCCIS. The UNIVERGE SV8100 Voice over IP Trunk Blade H.323
package sends the real-time voice over the corporate LAN or WAN. The voice from the telephone is
digitized and then put into frames to be sent over a network using Internet Protocol.
The UNIVERGE SV8100 Voice over IP Trunk – H.323 blade package allows communication using
standard H.323 (Normal and Fast Start) Protocol and allows connectivity to any H.323 standards
compliant voice gateway and gatekeeper. This VoIP Trunk Blade also allows Registration and
Authentication Server (RAS) support to register with an RAS Server and use Gatekeeper for dynamic call
routing.
The PZ-(x)IPLA blade – H.323 is an optional interface that can provide IP trunks and Tie Lines. It can
operate in the following modes:
COI
COID
DID
TLI
DTI
Depending on the requirements and resource allocation in the LAN/WAN/Internet, the IAD(8)-U( ) ETU -
H.323 can be configured to use any of the following voice compressions:
G.729 Low bandwidth requirement, and is used on most Wide Area Network links.
G.711 High bandwidth requirement - usually used on Local Area Networks.
G 722 This codec is useful in fixed network, Voice over IP applications, where the required
bandwidth is typically not prohibitive.
G.723 This codec is a ITU-T standard wide band speech codec. This is an extension of
Recommendation G.721 adaptive differential pulse code modulation to 24 and 40 kbit/s for digital
circuit multiplication equipment application.
