RDS ODA-1 ODA-2 (Tuner-1 Tuner-2)
This test checks alarms and traps on ODA services of a Radio tuned on frequency 100.5MHz.
The test was carried out on both tuners and performed on each ODA service.
The system can monitor either two user specific registered ODA services on tuned radio.
Control parameters are similar to those one of TMC and RT+. In addition we found an input mask for the Application ID
(AID) related to each ODA service (a four digit hexadecimal field).
Alarm conditions raise up as we’ve seen in TMC and RT+ tests. Moreover, like as for TMC and RT+, data prints (e.g.
“NO DATA”, “NO REG”, etc.) follow the same rules.
For the test in Static Mode we have tuned on 100.5 MHz a radio that broadcast an ODA1 service with AID=5A14.
We set Data Timeout=20 sec. Group Timeout=30 sec. and Hold Time=40 sec.
Tested in Scan mode with 3 frequencies:
F1: 100.5 MHz
F2: 95.3 MHz
F3: 96.7 MHz
AID=5A14 - Data Timeout=20 sec.
– Reg. Timeout=30 sec. - Hold Time=40 sec. as depicted below.
Tested in SmartScan with the same setup depicted above for ‘normal’ Scan Mode.
If an alarm condition is found on a channel, instead of state an alarm condition, system stops on channel for a period
(depending on tested service that cause alarm condition) collecting more data. In this state no alarm or Trap was
reported. The Channel Memory index reports the cause(s) of the stop (see below: “1 of 3 (ODA1)”).
