7845 ISDN NT Extended

   The 7845 Network Terminator Extended connects analog telephone equipment over the same ISDN service.  The second B channel is converted into a standard analog interface.  This allows the 7845 ISDN Network Terminator Extended to drive an existing telephone loop at the customer premises, or to provide an additional analog service, at the same time providing a digital data connection to the terminal equipment. 
       A single ISDN service can provide a digital data connection and a standard analog telephone service that operate independently and concurrently. 
       The 7845 ISDN Network Terminator Extended can also act as a standard NT1, passing both B channels and the D channel to the terminal equipment. 
    When using analog telephone equipment, the Network Terminator Extended offers several custom calling features similar to those offered by the telephone companies as options with regular analog telephone service.  These features are: 
o   Speed Dialing 
o   Re-dial of last number dialed 
o   Repetitive re-dialing of the last busy number 
o   Return of the last incoming call 
o   Call Hold 
o   Call Retrieve 
o   Call Waiting 
o   Three or Six-way Conferencing 

By being able to program the 7845 ISDN Network Terminator Extended for the desired custom calling features, the Network Terminator Extended can provide much of the flexibility you have with your present analog phone service. 

BATTERY BACKUP:  A rechargeable battery provides  backup power to the analog phone service, if the home or office experiences a power outage.  The included battery, when fully charged, provides up to 18 hours of standby power (up to six hours off hook).  An audible alarm is superimposed on the call when approximately 10 minutes of power remain. 
       Traditional analog telephone sets receive electrical power from the telephone company central office.  Therefore, phone service is not interrupted if your home or office should lose A/C power. 
ISDN phones and network terminators must be powered from electrical outlets in the home or office.  Therefore, a neighborhood power failure normally causes a loss of phone service.  The battery backup feature ensures the customer will not lose the analog telephone service provided through the NT Extended during power outages lasting up to 18 hours (up to six hours off-hook). 

Connecting the WaveRunner to the NT1
        1. To attach the WaveRunner to the NT1, you will  need the cable with RJ-45 connectors (incl.with adapter). connect one end of the cable to the adapter Warning Do not connect a headset or handset to the WaveRunner. Doing so may cause  damage to the headset or handset. 
        2. Connect the other end of the cable to the NT1 in the slot marked TE or S/T. Or, if the NT1 is part of the ISDN, connect the other end of the  cable to the wall socket.
