Each row item appearing in the Network Area is described below.
• ISDN and ATM Network Services - This section describes the
available bandwidth, in Bearer Channels (B channels), for each type of
ISDN and ATM network connection. Only the installed types of
connections are displayed:
— 155 - Number of B channels available with an ATM-155 Mbps card
—
25 - Number of B channels available with an ATM-25 Mbps card
—
E1 - Number of B channels available with E1 ISDN spans
— T1 - Number of B channels available with T1 ISDN spans
• T1-CAS Network Services - This section describes the available
number of channels (B channels) for each T1-CAS span. Each T1-CAS
span consists of 24 channels. Each T1-CAS (Audio Only) participant is
allocated one network channel and one Audio+ port.
• MPI Network Services - This section describes the available number of
ports for each type of MPI connection - Data Terminal Equipment (DTE)
or Data Communication Equipment (DCE). For more information about
these types of MPI connections, see “Defining an MPI Network Service”
on page 3-99. Only the installed types of connections are displayed:
— DCE - The number of ports configured as DCE
— DTE - The number of ports configured as DTE
•
IP Services - IP resources per participant type. This section describes the
available ports for each possible type of IP (H.323 and SIP) participant.
The available number of ports in any particular row represents the
total
bandwidth and resources available for all types of participants , so if
one type of participant were to use some resources, the available
resources for all other types of participants (rows) would be less.
The Resources Report displays the total number of IP ports available
according to the Conference Type, Line Rate, and Encryption in the
format:
Media_Line Rate_Conference Type . Media may include Voice , Video or
Encrypted Video ports. For example: VOICE_ONLY, designating Audio
Only participant resources; VIDEO-128-SOFT_CP, designating video
participants using a line rate of 128 Kbps in a Software Continuous
Presence conference.
