ATLAS 800 Series System Manual VCOM Option Module
Status
Frame Type Read security: 5
Displays the kind of frame the ATLAS 800 Series receives from the frame relay
endpoint connected to the VCOM channel, allowing users to monitor the kind of
data being carried on the network and processed by the ATLAS 800 Series. (The
ATLAS 800 Series interprets the most-recently received frame from the
endpoint.)
During a voice connection, the frame type displays as
VOICE. For a FAX
connection, a variety of frame types display. Initially,
VOICE displays indicating
that although the call has completed, the answering FAX machine has not yet
announced its 2100 HZ tone. After completing the 2100 Hz, both FAX
endpoints repeat a V.21 cycle for each page of the FAX document.
Each packet the ATLAS 800 Series receives from its connected frame relay
endpoint is classified into one of the following groups:
Some voice compression standards may be used only under specific licensing
arrangements due to existing patents. The ATLAS 830 provides complete management
of these licensed resources; therefore, users are not required to take additional steps to
ensure conformance with licensing provisions. For example, the ATLAS 830 manages
its resources so users never exceed the maximum licensed number of simultaneous
connections.
