The following packet is a data packet from N7ALW to WA7GCI.
N7ALW*>WA7GCI:
Hi Bob, how are you this evening?
Remember that in the first example we saw the two stations Connect.
Now that they are connected, they may exchange data packets.
The following packet is a Beacon packet from KD7NM. Since we see the
packet is addressed to "MAIL" we know KD7NM is probably a Packet
Bulletin Board System (PBBS).
KD7NM*>MAIL:
Mail for: K6RFK N7ML
The data section of this packet says "Mail for: K6RFK N7ML". This
Beacon lets people know that K6RFK and N7ML have mail waiting on the
KD7NM PBBS without having to connect.
The following Beacon packet is intended as identification for a
NET/ROM level-3 packet networking switch.
N7HWD-8*>ID:
NET/ROM 1.3 (SEA)
In this case, the Packet Switch is using the callsign N7HWD-8, but
also uses the alias SEA as a callsign. There are many types of Packet
Switches now in use, but NET/ROM is one of the most popular. We will
briefly discuss using a NET/ROM switch later in this chapter since
most switches operate in much the same way.
The packet below was sent by the network switch SEA to N7ML.
SEA*>N7ML:
SEA:N7HWD-8> Connected to #SEA:N7HWD-7
The packet above from SEA contains the data "SEA:N7HWD-8> Connected to
#SEA:N7HWD-7". This message tells N7ML that he is now connected to
another port on the SEA Node named #SEA. Again, we will talk more
about how and why N7ML might want to do this later in the chapter.
The following packet is again from K6RFK to N7GMF and is being
digipeated through N7ALW. This packet indicates that K6RFK is
finished talking to N7GMF and wants to Disconnect. Again we see that
we are not hearing K6RFK, rather we are hearing N7ALW as indicated by
the asterisk (*) after his call.
K6RFK>N7ALW*>N7GMF [D]
The following packet is an acknowledgment (or simply called an ACK)
that lets K6RFK know that N7GMF has acknowledged the Disconnect
request sent above. K6RFK and N7GMF are no longer Connected.
N7GMF>N7ALW*>K6RFK (UA)
4/91 4-7
