Specifies the maximum propagation delay of the link for
the TG. Propagation delay represents the time needed for a signal
to travel from one end of the link to the other.
- PDELAY=NEGLIGIB
- Indicates a local area network delay (less than .48 milliseconds).
- PDELAY=TERRESTR
- Indicates telephone network delay (between .48 and 49.152 milliseconds).
- PDELAY=PACKET
- Indicates a packet-switched network delay (between 49.152 and
245.76 milliseconds).
- PDELAY=LONG
- Indicates a satellite delay (greater than 245.76 milliseconds).
Recommendations: - When specified on the PORT statement, VNGROUP and VNNAME (or VNTYPE=GLOBAL)
must also be specified on the PORT statement and the value applies
to the TG to the connection network specified in VNNAME (or IP.IP
if VNNAME is defaulted for VNTYPE=GLOBAL).
- When specified on the GROUP statement, VNNAME or VNTYPE=GLOBAL
must also be specified on the GROUP statement. If the GROUP is not
defined as a connection network, the TG characteristics cannot be
specified on the GROUP definition statement. They must be specified
on the PU definition statement in the switched major node (or for
dynamically created dial-in EE PUs on the DYNTYPE=EE model major node)
for the PU being dialed to establish the connection.
Guideline: Although an Enterprise Extender connection
network, including the virtual node name, type, and all TG characteristics,
can be defined on the PORT definition statement, you should define
your Enterprise Extender connection network on the corresponding GROUP
definition statement instead. By coding all connection network and
TG characteristics operands on the GROUP statement, the VNGROUP operand
is no longer needed. Also, because there can be multiple connection
networks defined in an Enterprise Extender XCA major node with multiple
GROUP definition statements, defining all of the operands on the GROUP
statement to which they apply provides more clarity.
