TNs

For Nortel IP Phones, there are two kinds of TNs to consider:
• physical TN – represents a physical unit of the Voice Gateway Media
Card
• virtual TN – configured on a virtual superloop and represents an IP
Phone
Physical TNs
Physical TNs, that are seen as trunk units, are managed using existing LD 32
commands.
Virtual TNs
Because virtual TNs are configured on a virtual superloop, virtual TN
maintenance has no meaning; that is, what is already provided by the
Meridian 1 and CS 1000 for phantom loops.
In LD 32, any command affecting a phantom loop leads to an NTP665
message because the loop does not physically exist. LD 32 supports STAT,
DISU, ENLU, and IDU commands on an IP Phone Virtual TN. All other
commands generate the NPR047 message.
ECNT PEC <PEC> Prints the number of IP Phones with specified PEC, where:
<PEC> – Product Engineering Code
ECNT PEC is equivalent to ECNT PEC ALL; that is, the list containing
the PECs and the quantity of IP Phones with this PEC is printed.
