Data Channel Local Loop Back Test (#111)
This test verifies the integrity of the dual por t RAM that is shared between the
software and hardware that comp oses the DATA-CHL. The dual port RAM is
placed in loc al loop back mod e such that data to be sent b y the DATA-CHL is
instead looped b ack to be received by the DATA-CHL. The loop back is done
within the dual port RAM, that is, the d ata is never sent over the TDM Bus. The
test checks that the data rec eived by the DATA-CHL is the same as the data that
was sent by the DATA-CHL.
NOTE:
If an Error Code is encountered that recommend s that an CDR Link, System
Printer Link, PMS Log Printer, Wakeup-Log Printer, and/or PMS Link be
busied out, restore each b usied-out link to service ac cording to the
PRI-CDR/ SEC-CDR ( PRI-CDR L ink), SYS-PRNT (Sys tem Pri nter L ink),
PMS-PRNT/J NL-PRNT ( PMS Print er Lin k), or PMS-LIN K (Prop erty
Management System Link) Maintenance do cumentation, respectively,
before concludi ng work on the problem.
PASS The target DATA-CHL, Processor circuit pack, TDM Bus (TDM-BUS), and
Tone-Clock circuit pack (TONE-BD, TONE-PT, TDM-CLK) are functioning.
Connections can be established over the target DATA-CHL.
