Narrative:

Conducting OJT with developmental at sector. Working sector 36 (ultra-high FL340-FL600) with approximately 8 aircraft on frequency. Fsop's require san arrs to cross eed VOR at FL300. Aircraft X at FL360 was issued a crossing restr of FL300 at eed with a good readback (pointout to sector 35 (FL240-FL330) approved). Approximately 8 mi from eed developmental noticed that aircraft X had not started descent. Developmental questioned aircraft X about restr and pilot responded; 'we're descending to FL300.' we coordination with receiving controller for 'descending to FL300;' then shipped aircraft X to ZLA 39. Good clearance; good readback; so I'm not sure what happened on the flight deck. On occasion; there is east/west traffic on J6 that is in confliction with this type of operation and we count on the eed at FL300 to clear that traffic. In this case -- no harm; no foul. We should have caught the lack of altitude change sooner; but were distraction by other traffic.

Title: ZLA CTLR PROVIDING OJT DESCRIBED ACR ALT CROSSING FAILURE; SUGGESTING HE AND/OR THE STUDENT SHOULD HAVE NOTED THE LACK OF DESCENT SOONER.

Narrative: CONDUCTING OJT WITH DEVELOPMENTAL AT SECTOR. WORKING SECTOR 36 (ULTRA-HIGH FL340-FL600) WITH APPROX 8 ACFT ON FREQ. FSOP'S REQUIRE SAN ARRS TO CROSS EED VOR AT FL300. ACFT X AT FL360 WAS ISSUED A XING RESTR OF FL300 AT EED WITH A GOOD READBACK (POINTOUT TO SECTOR 35 (FL240-FL330) APPROVED). APPROX 8 MI FROM EED DEVELOPMENTAL NOTICED THAT ACFT X HAD NOT STARTED DSCNT. DEVELOPMENTAL QUESTIONED ACFT X ABOUT RESTR AND PLT RESPONDED; 'WE'RE DSNDING TO FL300.' WE COORD WITH RECEIVING CTLR FOR 'DSNDING TO FL300;' THEN SHIPPED ACFT X TO ZLA 39. GOOD CLRNC; GOOD READBACK; SO I'M NOT SURE WHAT HAPPENED ON THE FLT DECK. ON OCCASION; THERE IS E/W TFC ON J6 THAT IS IN CONFLICTION WITH THIS TYPE OF OP AND WE COUNT ON THE EED AT FL300 TO CLR THAT TFC. IN THIS CASE -- NO HARM; NO FOUL. WE SHOULD HAVE CAUGHT THE LACK OF ALT CHANGE SOONER; BUT WERE DISTR BY OTHER TFC.
