Paired Digital Feature Phone/analog phone o
peration 
For someone wishing to have a Digital Feature Phone in his office and a cordless phone for roaming 
the building: 
1. 
Create a call forward key on the Digital Feature Phone to forward to the cordless phone. 
2. 
Program the call forward busy/no answer for the cordless station to the Digital Phone’s mail-
box. The user will then have all of his messages in one location (however, he/she can retrieve 
them from either phone). 
Overhead paging interface 
You can connect a dry-contact overhead paging device to the system through the first port card’s 66 
block. The overhead paging port’s access is fixed as extension 199 for programming purposes. The 
user can access it by: 
 (a.) Dialing 
1 9 9
 or  
 (b.) Programming 
199
 as a programmable key 
    and /or including 
199
 in one or more page zones. 
Note:
  DTMF can be transmitted to the overhead paging port after access, allowing for zone over-
head paging, if the paging unit supports zone paging.
