4.10.6 Add/Edit Profile Menu
Access the
Profile Menu
from the
ATM Menu
. Then press the Profile softkey. Change
the option to ‘Active’ and press the Enter softkey.
Table 4.36: Add Profile Options
Selected Option Description
Active A new default Profile is created and the menu moves directly to
the Edit screen for the new profile.
Not Active
This shows the Edit Profile screen which displaqs a further set of options which define the
connection parameters used to establish a connection to the network. Multiple profiles can be
added to the list, defining different endpoint addresses or parameters.
Table 4.37: Edit Profile Options
Selected Item Options Description
Profile Name Use the keypad to amend the profile name (if necessary).
SVC PP Switched Virtual Circuit (SVC).Point-to-Point (PP). PP indicates transmission to
a single Receiver.
SVC PMP Switched Virtual Circuit (SVC). Point-to-Multi-point (PMP). PMP indicates
simultaneous transmissions to several Receivers
PVC Permanent Virtual Circuit (PVC) connection.
VC Type:
This option enables the VC
Type to be set.
An SVC is a circuit which only exists for the duration of the session, after which it is usually disconnected. Also
referred to as “Bandwidth on-Demand”. A connection established via signalling.
A PVC is a circuit, equivalent to a dedicated leased line, yet over some form of packet switched network. A PVC
is set up once, usually through the management system of the network supporting it, and continues to exist until
it is removed, again via the management system.
ATM Address:
Allows an ATM address
value to be input. 0 to 255 Enter the ATM address value.
This option is only shown when VC Type = SVC PP or SVC PMP.
VPI:
Allows a Virtual Path
Identifier value to be input. 0 to 255 Enter the Virtual Path Identifier (VPI) value.
This option is only shown when VC Type = PVC.
50 to 65535
Values less than 49 are
reserved. Virtual Channel Identifier.
This option is only shown when VC Type = PVC. VCI:
Allows a Virtual Channel
Identifier value to be input.
Virtual Channel Identifier – a unique numerical tag as defined by a 16 bit field in the ATM cell header that
identifies a virtual channel, over which the ATM cell is to travel.
TX Transmit direction.
RX Receive direction.
Direction:
Enables the Direction to be
set.
TXRX Bi-directional.
AAL-1 FEC ATM adaptation layer and Forward Error Correction, used with the MPEG
transport stream.
AAL-1 ATM adaptation layer without Forward Error Correction, used with the MPEG
transport stream.
AAL-5 ATM adaptation layer, used with the MPEG transport stream and ATM
signalling.
AAL:
Enables the selection of an
ATM adaptation layer used
with the MPEG transport
stream.
ATM Adaptation Layer – the standards layer that allows multiple applications to have data converted to and
from the ATM cell.
