Broadcast Host™

 

Analog Desktop Digital Hybrid

 

Auxiliary Telephone

 

An auxiliary telephone provides you with an easy way to dial out or set up your 

calls. Broadcast Host will disconnect the auxiliary telephone when you press the 

<Call> button. If you need to take the call back on the aux telephone, simply pick 

up the telephone handset before the Broadcast Host’s <Drop> button is pressed. 
To use an auxiliary phone equipped with a “Hold” feature to place or screen a 

call, first set up the call and place the call on hold. When you are ready to take 

the call on Broadcast Host, press the <Call> button on the Broadcast Host and 

your telephone will automatically release the hold. 
Your phone will operate as a normal telephone anytime you are in Drop mode. 

Leaving the hybrid connected between the wall jack and your telephone will not 

affect normal use of your phone. Audio will only pass through the hybrid when 

you press the <Call> button.

Optional Jumper Settings

 

If the incoming Caller level is too high and peaking the red -3 dB LED, you may 

need to change the setting of an internal jumper. Disconnect power from the 

hybrid and remove the cover of the Broadcast Host to locate Jumper 1. The 

default position for this jumper is closed (covering both pins). Changing the 

jumper to the open position (either remove the jumper or cover just one pin) will 

provide 6 dB attenuation of the incoming audio signal.

Auto-Answer

The <Auto-Answer> feature will answer on the first ring. When <Auto- Answer> 

is enabled, you can still make calls manually using the <Call> button. 

When finished, you can either drop the call manually or allow the call to 

Auto-Disconnect. Broadcast Host will look for a CPC disconnect signal from the 

phone company to determine when a call has disconnected. This can take up to 

a minute.
