H.320 H.320 is a protocol for defining videoconferencing over ISDN networks.
H.323 H.323 is a widespread set of protocols governing the communication
between endpoints in videoconferences and point-to-point calls. It defines
the call signaling, control, media flow, and bandwidth regulation.
H.323 Alias See Alias on page 201.
H.350 H.350 is the protocol used to enhance LDAP user databases to add video
endpoint information for users and groups.
H.460 H.460 enhances the standard H.323 protocol to manage firewall/NAT
traversal, employing ITU-T standards. Endpoints which are already H.460
compliant can communicate directly with the PathFinder server, where the
endpoint acts as an H.460 client to the PathFinder server which acts as an
H.460 server.
HD
A HD ready device describes its high definition resolution capabilities of
720p, a video resolution of 1280 x 720 pixels.
High Availability High availability is a state where you ensure better service and less
downtime by deploying additional servers. There are several strategies for
achieving high availability, including deployment of redundant servers
managed by load balancing systems.

HTTPS HTTPS is the secured version of the standard web browser protocol HTTP.
It secures communication between a web browser and a web server
through authentication of the web site and encrypting communication
between them. For example, you can use HTTPS to secure web browser
access to the web interface of many Scopia

KBps Kilobytes per second (KBps) measures the bitrate in kilobytes per second,
not kilobits, by dividing the number of kilobits by eight. Bitrate is normally
quoted as kilobits per second (kbps) and then converted to kilobytes per
second (KBps). Bitrate measures the throughput of data communication
between two devices.
kbps
Kilobits per second (kbps) is the standard unit to measure bitrate,
measuring the throughput of data communication between two devices.
Since this counts the number of individual bits (ones or zeros), you must
divide by eight to calculate the number of kilobytes per second (KBps).
LDAP
LDAP is a widespread standard database format which stores network
users. The format is hierarchical, where nodes are often represented
