Narrative:

Simultaneous visual approachs in use to runway 8 and runway 10. I was working west control sequencing to lagoon visual runway 8 approach. Aircraft X, a DH8 inbound from southwest descending to 1500 ft intercepting the runway 10 localizer, did not see the airport until he had penetrated the sju tower's local radar approach control airspace. I had been trying to call the tower on the local control override and the shout line but could not get a response. By the time I attempted to turn the aircraft out, he reported the airport in sight and I cleared him for the approach. The override line has not worked properly since the icss was worked on. It worked only periodically since it (the icss) was installed. The shout line is used by east control, west control, west final control, and flight data position. Flight data is called by the tower (ground control) to pass the departure line up. The line is tied up until you 'break for control' then you have to wait for ground control to tell local control to 'pick up' the line. In an approach control environment with radar-to-radar this seems inadequate.

Title: RPTR AT SAN JUAN CENRAP HAD TROUBLE TRYING TO CONTACT THE TWR ON EITHER OF THE 2 VOICE LINES. RPTR ALLEGES THAT THE OVERRIDE LINE ONLY WORKS PERIODICALLY AND THE OTHER LINE, THE SHOUT LINE, TAKES TOO LONG TO GET SOMEONE AT THE TWR. THIS SIT WAS BROUGHT TO LIGHT BY THE RPTR BECAUSE OF ACFT PENETRATING THE TWR'S LCL RADAR APCH CTL AIRSPACE WITHOUT PRIOR COORD.

Narrative: SIMULTANEOUS VISUAL APCHS IN USE TO RWY 8 AND RWY 10. I WAS WORKING W CTL SEQUENCING TO LAGOON VISUAL RWY 8 APCH. ACFT X, A DH8 INBOUND FROM SW DSNDING TO 1500 FT INTERCEPTING THE RWY 10 LOC, DID NOT SEE THE ARPT UNTIL HE HAD PENETRATED THE SJU TWR'S LCL RADAR APCH CTL AIRSPACE. I HAD BEEN TRYING TO CALL THE TWR ON THE LCL CTL OVERRIDE AND THE SHOUT LINE BUT COULD NOT GET A RESPONSE. BY THE TIME I ATTEMPTED TO TURN THE ACFT OUT, HE RPTED THE ARPT IN SIGHT AND I CLRED HIM FOR THE APCH. THE OVERRIDE LINE HAS NOT WORKED PROPERLY SINCE THE ICSS WAS WORKED ON. IT WORKED ONLY PERIODICALLY SINCE IT (THE ICSS) WAS INSTALLED. THE SHOUT LINE IS USED BY E CTL, W CTL, W FINAL CTL, AND FLT DATA POS. FLT DATA IS CALLED BY THE TWR (GND CTL) TO PASS THE DEP LINE UP. THE LINE IS TIED UP UNTIL YOU 'BREAK FOR CTL' THEN YOU HAVE TO WAIT FOR GND CTL TO TELL LCL CTL TO 'PICK UP' THE LINE. IN AN APCH CTL ENVIRONMENT WITH RADAR-TO-RADAR THIS SEEMS INADEQUATE.
