Part No. 001-5100-001
Each SMARTNET/SmartZone system can be pro-
grammed with up to 256 talk groups.
- Clicking this button deletes the cur-
rently selected talk group (the one displayed in the
“Talk Group” box).
Failsoft Channel
Enable
- Enables a failsoft channel on the talk group
if a controller failure occurs (see Section 2.7.11).
Disable
- The failsoft mode is not entered if the con-
troller fails.
Tx/Rx Frequency
- Programs the failsoft channel
frequency if “Enabled” is checked.
Analog/Project 25
This selects the type of SMARTNET/SmartZone
channel as analog or Project 25 (digital).
Strapping Parameters
The Strapping Parameters program the channel
type (analog or Project 25 digital) and encryption on
the talk group as follows:
Clear Mode
- All transmissions on the talk group
occur in the clear (unscrambled) mode.
Coded Mode
- All transmissions on the talk group
occur in the secure (scrambled) mode selected as
follows.
Switched Mode
- The clear or secure status of the
talk group is selected by the Clear/Secure option
switch.
NOTE: Refer to Section 2.7.15 for more
SMARTNET/SmartZone encryption information.
460 Scrambling/SecureNet Mode
- These options
select either the Transcrypt 460 or DES type of
secure communication when either the coded or
switched strapping mode is selected.
Tx DES/DES-XL
- Selects either DES or DES-XL
encryption protocol.
Rx Secure Autodetect
- With the SecureNet protocol,
selecting “Secure” enables automatic detection of
encrypted receive signals. This may increase the
response time of the radio to an incoming signal.
Selecting “Proper Key” causes the radio to search the
available SecureNet keys until it finds a match for the
current transmission.
Encryption Key
- Selects the encryption key used on
the talk group. This is a number from 0-15 that refers
to a hardware location in the radio that contains the
real key.
