roaming decoder II
PCD5013
i:
Local ID (Table 59). A Local ID along with the Coverage
Zone, Country Code and Traffic Management Flags define
a specific simulcast coverage area for SSID roaming.
C:
Coverage Zone (Table 59). A Coverage Zone along
with a Local ID, Country Code and Traffic Management
Flags define a specific simulcast coverage area for SSID
roaming.
m:
month field (Table 59). 0001 to 1100 binary
correspond to January to December in month order.
d:
day field (Table 59). 00001 to 11111 binary correspond
to 1 to 31 days in the month.
Y:
year field (Table 59). This represents the year with
modulo 32 arithmetic. 00000 to 11111 binary representing
years 1994 to 2025 and 2026 to 2057.
S:
seconds field (Table 59). This represents a coarse
value of the seconds field. These bits represent the
seconds in
1
8
minute (7.5 s) increments.
000 to 111 binary correspond to 0 to 52.5 seconds.
M:
minute field (Table 59). 000000 to 111011 binary
correspond to 0 to 59 minutes.
H:
hour field (Table 59). 00000 to 10111 binary
correspond to 0 to 23 hours.
L:
daylight savings time (Table 59). When this bit is set,
the time being transmitted is local standard time. When it
is clear, the time being transmitted is daylight savings time.
z:
time zone (Table 59). These bits indicate the time zone
for the time which is being transmitted. The offset
from GMT is the offset for local standard time. Table 60
describes the values for z.
c:
Country code (Table 59) identified in the CCITT (ITU-T)
Standard E.212, Annex A.
T:
Traffic management flags (Table 59). indicate a
possible assignment of any combination of 4 groups of
traffic to an RF channel. Each roaming subscriber unit,
after finding an RF channel which matches its
programmed Local ID, Coverage Zone and Country Code
responds to only one of the 4 Traffic Management Flags.
When one or more of the transmitted Traffic Management
Flags are set to O, subscriber units assigned to those
traffic groups must find another RF channel with the same
LID, Coverage Zone and Country Code information with its
assigned Traffic Flag set to 1.
