The CCB also provides the following standard connectors:
• Music Channel 1 ‐ On Hold/Background Music Interface
• Music Channel 2 ‐ On Hold/Background Music Interface
• Control Contact (Loud Bell or External Page Relay)
• External Paging Equipment Interface
• RMP Serial Port ‐ for on ‐ site database programming
• SMDR Serial Port ‐ for connection to ancillary SMDR/Call Accounting equip ‐
ment
The CCB has two Option Strap jumpers one for database start ‐ up (J7) and one for
Music Channel One source (internal/external) selection (JP81).
• JP7 Cold Start/Normal : JP7 is used to force load database default factory
settings. This jumper will normally never require operation after the initial
power up sequence is completed. However should the need arise to return
the site database to the factory settings this jumper is used to accomplish the
task.
• JP81 Internal/External : J81 is used to select the Music Channel 1 source. The
Emerald ICE provides a synthesized music source for music on hold in appli ‐
cations where no music source is available. The synthesized tune is repeated.
JP81 is in the “External” position when it ships from the factory.
The CCB is equipped with a Heart ‐ beat LED that indicates processing activity on
the PCB. (The 610+2 peripheral processor is operating when the Heartbeat LED is
flashing.) The KSU1 operation LED (located next to the power switch) is tied to
the CCB Heartbeat LED. Therefore, when the LED next to the power switch is
flashing, the CCB is active..
