commands (depending on the Virtual circuit type chosen) entered form the
SYSTEM_REQUEST command entry line from the terminal initiating communication with
the host.
Packet Size The number of bytes allowed in the data field of the
packet.
For SVCs , this parameter configures the maximum size
of call packets accepted by the controller - it sets the
limit on variable packet sizes.
For PVCs , the packet size value is not negotiable and
remains constant at the value selected.
0 = 64-byte packet
1 = 128-byte packet
2 = 256-byte packet
3 = 512-byte packet
Virtual Circuit Type This is the type of connection:
[1] = PVC only. Permanent Virtual Circuit; emulates
"End to End" connection.
[2] = SVC Ans. Incoming calls only; choose this option
ONLY if you do not intend to place any calls to the Host.
[3] = SVC Calls. Outgoing calls only. Choose this
option only if you do not intend to receive incoming calls
from the host system.
